You’ve been at your job for years, you know how to write code good enough to get you by comfortably, yet every now and then there’s a ticket, a ticket that lingers on-and-on on that kanban board, red with delays, reschedules and “is this done?” comments. “I’ll pick it up first thing in the morning” is what you told yourself yesterday, and the day is already dusking off. <img src="https://media4.giphy.com/media/5q3NyUvgt1w9unrLJ9/200w.gif?cid=6c09b952va9i6h9jue6xqe50vw4o7n9vbwl2cfvn3jbwxnc1&ep=v1_gifs_search&rid=200w.gif&ct=g"/> We as programmers and developers are likely to procrastinate, and there are good enough reasons for it. And being lazy might be one of them, but the documentation of our brains is much bigger than that. ## Why programmers are likely to procrastinate ### Cognitive overload 😵‍💫 As problem-solvers, we tend to use the ‘most-contextual’ part of the brain way too often, i.e the **Frontal Cortex**. The frontal cortex is responsible for executive functions, which involve analyzing information, identifying patterns, decision making, and most importantly, _doing-the-right-thing-even-if-it-is-the-hard-thing-to-do_ actions. <img src="https://i.pinimg.com/originals/00/69/51/0069513d884baad8cee121e091fb51ad.gif"/> For these seemingly-simple tasks, the frontal cortex needs **bucket-loads of energy**, exhibiting a very high metabolic rate. We, as mere mortals with anti-bluelight glasses, have fixed reserves of energy, and when we expend them, compromises start to occur. _Behave’s_ author Sapolsky point out that when the frontal cortex is overloaded, subjects become less prosocial, they lie more, are less charitable, and are more likely to cheat on their diets. > “Willpower is more than just a metaphor; self-control is a finite resource”, he says, stating that _doing-the-right-thing-even-if-it-is-the-hard-thing-to-do_ is not merely an emotional and moral choice, but is far deeply tied to the physiology of the brain. ### I’m just a kid We have all had our fair share of beginner-developer moments. When we plowed through nights and days trying to learn and retain how that _x_ language or _y_ framework functions. And the number of times we almost gave up. <img src="https://gifdb.com/images/high/what-a-noob-puppet-misyfy7rmepive8a.gif"/> But after a certain threshold, coding didn’t seem to have that big of a draining effect. And there’s a good reason for it. When we practice and learn something, we start shifting the cognitive processes to the more reflexive (stemming from a reflex action, an automatic “muscle memory”) parts of the brain, like the cerebellum. And once that is achieved, we reduce the burden of computation on the Frontal cortex, making the tasks less energy-taxing. ### Decision Fatigue Cognitive tasks are not limited to logic-oriented, calculative, cautious tasks that one does as a programmer. It also includes a seemingly simple task: **Decision making**, like using the correct approach to write readable code, or something as simple as which task should I ship first? And like cognitive loads, decision-fatigue is tied to your energy reserves too, and can ultimately affect your productivity. ## Process rather than Procrastinate Now that we have broken down Procrastination, it's time to actually tackle it. ### 1. Germinate To achieve anything, whether it’s your jira-ticket’s completion, or a side project, one must start to build. _“Am I taking the most efficient, readable, perfectly orchestrated approach to solve this problem”_; the friction of uncertainty and self doubt usually make it hard enough to begin with. Opening your laptop is the first victory to overcome the code-block. And the only way to do that is to have something certain, some anchor that doesn’t give you any unease. <img src="https://media4.giphy.com/media/ZXWWsIMwaHjiHMtNf4/200w.gif?cid=6c09b952ibhnhiqzxzxah6ue2m3owb9grbhswhlclie2nk62&ep=v1_gifs_search&rid=200w.gif&ct=g"/> I’ve had times where I tried to find a perfect time window to start programming on a weekend, that was me trying to find a unicorn. So I made it a point that at a certain hour in the morning, I will open Monkey Type and try to hit the day’s first 80+ words a minute. It’s something I stole from Atomic Habits, and it helped immensely. This simple ritual in the first 5 minutes of my day consisted of adrenaline-rushed, muscle-memory reflexes that had nothing to do with uncertainty of my task. Thus, I could be eased into opening my IDE to complete that Jira ticket, whose dread had haunted my jira board for a week. ### 2. Granular-ize Something I learnt fairly recently is to plan in a way that your programming journey will have little to no decision making once you start with writing code. Everything else can, and should be pre-planned, into its utmost smallest task-granules, making things as clear as they possibly can be. <img src="https://media2.giphy.com/media/Ig9dsuczC9dDkOKrIa/200w.gif?cid=6c09b952ay2xn8tymf29sg01ctdyj2c08tiwrwybh1uymklh&ep=v1_gifs_search&rid=200w.gif&ct=g"/> The concept of **Engineering Requirements Document** (ERDs) was something I looked down upon as a corporate scut-work for the upper management to feel included in the process. Turns out I was wrong, and it’s intended to make sure that all the decision fatigue occurs during initial stages, and the rest of the shipment of tickets spread throughout the week remains relatively unharmed from taxing your Frontal cortex’s energy reserves. ### 3. Game-ify Updating my Jira tickets on my kanban board didn’t give me enough belongingness to the fruits of my labor. Neither was I able to track my personal progress of what I completed, what I shipped and what I spilled. <img src="https://www.jenlivinglife.com/wp-content/uploads/2019/01/gyi7eys35a32b61551d35012060362_499x280.gif"/> So I kept a set of my mini daily tasks on a local Microsoft’s To Do list. The satisfying chime of completing the task gave me a big boost on being on track, without having to worry about what is left undone and what is yet to be picked up. Since this was personal, I could add tasks like “get a brownie on 3 completions” and wait for it to ping up when I marked it as done. Motivation is a cocktail of neurotransmitters, make sure you zap your brains with some hits, every now and then. Another tool that can help in the same is Middleware’s Project Overview. It systematically gave the reason for my spills and overcommitment in a sprint, and can help give an overview of your Jira Boards and Projects. ### 4. Gauge, Grapple and Give-up (not totally) Friction in the building process goes far beyond decision-fatigues. You fail at something for long enough and you are likely to not want to do that thing anymore. <img src="https://64.media.tumblr.com/tumblr_lifd0k25wJ1qaakxao1_500.gif" /> It's wise to gauge the problem, allocate a time-duration, and wrestle with the problem with all your might. But when you know that it’s time-up, ask for help. You need to make a voluntary decision to make the problem smaller than your hands, or add more hands to it. There’s nothing wrong with an extra set of limbs, or brains. Homo erectus showed the first signs of ordered-socialization within communities, and then came homo sapiens with their big-brains of computation. Companionship precedes cognition, at least within evolution. ## 5. Conclusion We as developers often forget how human we are, I mean we are running services that cater to millions of humans. >_Who are we, but gods on keyboards_? But, something as little as a missed breakfast can affect our productivity, and something as big as a system-failure can drive us to work harder. We are complex machines with simple values. As a developer who would rather write a script for an hour, rather than clicking 4 buttons in 4 seconds, I can vouch, it’s always wise to fix a process rather than the absolute problem. Fix habitual actions, and you fix procrastination.

https://dev.to/rishiabee/finding-your-true-north-a-concise-guide-to-authenticity-5cbp

authenticity, leadership, management

Authenticity. It's a word thrown around a lot these days, but what does it truly mean? At its core, authenticity is about being genuine, acting with integrity, and living according to your inner compass. It's the unwavering sense of "you" that shines through in your actions, decisions, and even your style. --- > "**The only person you are destined to become is the person you decide to be.**" - Ralph Waldo Emerson _(This quote emphasizes the power of self-discovery and living according to your own choices.)_ > "**The greatest danger for most of us is not that our aim is too high and we miss it, but that it is too low and we reach it.**" - Michelangelo _(This quote reminds us that true fulfillment comes from striving to be our authentic selves, even if it's challenging.)_ --- So, how can you cultivate your own authentic self? Here's your roadmap: - **Craft a Personal Manifesto:** Take time to reflect on your values, your passions, and your non-negotiables. Write them down! This personal manifesto will serve as your guiding light. - **Embrace Vulnerability:** Let people see the real you, flaws and all. Authenticity thrives on connection, and connection requires vulnerability. Share your passions, your struggles, and your true opinions. - **Consistency is Key:** While your style or hobbies may evolve, your core values should remain constant. This consistency builds trust and allows others to understand who you are at your core. - **Set Boundaries:** Respecting your limitations and saying "no" is crucial for authenticity. Don't spread yourself thin trying to please everyone. Prioritize what aligns with your values and protects your well-being. - **Know When to Stop:** Don't force a certain image or behavior. Authenticity isn't about maintaining a facade. It's about allowing your true self to shine through, even when it's messy or inconvenient. - **Transparency Matters:** Be honest and upfront in your communication. Authenticity doesn't mean blurting out every thought, but it does mean striving for genuineness. - **Embrace Your Range:** You can be both a nature enthusiast and a techie, a lover of classical music and a dab hand at baking. Embrace the multifaceted nature of your personality! Remember, authenticity is a journey, not a destination. There will be stumbles and moments of doubt. But by staying true to your core values and letting your genuine self shine through, you'll find the path to your own unique and powerful form of authenticity. --- > "**To thine own self be true.**" - William Shakespeare _(A timeless quote reminding us to stay faithful to our authentic selves.)_ --- ## The Stories Within Consider Sarah, a graphic designer with a whimsical, artistic streak. Her colleagues know her for her vibrant clothing choices and her infectious laugh. But when it comes to client work, Sarah is a meticulous professional, delivering polished designs that prioritize functionality. This is authenticity in action. Sarah embraces her full self, both the playful and the serious, without compromising her core values of creativity and excellence. Now, there's Michael, a history teacher known for his dry wit and passion for obscure historical events. At home, however, Michael is a devoted family man, indulging in silly movie nights with his kids. This apparent contradiction isn't inauthenticity; it's simply the multifaceted nature of a person. Michael's dedication to his students and his family stems from the same core value: a love for learning and connection. --- > "**Authenticity is a collection of choices that reflect your inner values.**" - Frederic Buechner _(This quote highlights that authenticity is an active process based on your core beliefs.)_ --- ## Be You, Unapologetically: Bullet points to Authenticity **Know Your Values:** Craft a personal manifesto that reflects your core principles and what matters most to you. **Embrace Vulnerability:** Let people see the real you, strengths and weaknesses. Build connections through open communication. **Live with Consistency:** While your style may change, your core values should remain constant. This builds trust and allows others to understand who you are. **Set Boundaries:** Respect your limits and say "no" when needed. Focus your energy on what aligns with your values and protects your well-being. **Be Transparent:** Strive for honesty and genuineness in your communication. **Embrace Your Multifaceted Self:** You can have a range of interests and passions. Authenticity celebrates the unique blend that makes you, you. **The Journey Matters:** Authenticity is a continuous process. There will be challenges, but staying true to yourself is the path to a fulfilling life. --- > "**Authenticity is the new rebellion.**" - Margaret Mead _(This quote suggests that living authentically can be a form of nonconformity in a world that often pressures us to fit in.)_ ---

As the digital landscape continues to evolve, businesses must stay ahead of the curve to remain competitive. Here are some of the key trends shaping the future of digital marketing in 2024: 1. AI and Machine Learning Integration Artificial Intelligence (AI) and Machine Learning (ML) are no longer just buzzwords; they are integral parts of digital marketing strategies. AI-driven tools can analyze vast amounts of data to provide insights into customer behavior, predict trends, and automate tasks. Chatbots and virtual assistants powered by AI enhance customer service by providing instant responses and personalized experiences. 2. Personalization at Scale Consumers expect brands to understand their preferences and deliver personalized experiences. Advanced data analytics and AI enable marketers to create highly targeted campaigns that resonate with individual users. Personalization extends beyond email marketing to include dynamic website content, personalized product recommendations, and tailored social media ads. 3. Voice Search Optimization With the increasing use of smart speakers and voice-activated devices, optimizing for voice search is becoming crucial. Voice search queries are typically longer and more conversational, requiring a shift in SEO strategies. Marketers need to focus on natural language processing and optimizing content for voice-specific keywords. 4. Video Marketing Dominance Video content continues to dominate digital marketing, with platforms like YouTube, TikTok, and Instagram Reels leading the charge. Live streaming, interactive videos, and short-form content are particularly effective in capturing audience attention. Marketers should invest in high-quality video production and leverage storytelling to engage viewers. 5. Sustainability and Social Responsibility Consumers are increasingly concerned about the ethical and environmental impact of their purchases. Brands that demonstrate a commitment to sustainability and social responsibility can build stronger connections with their audience. Transparency in supply chains, eco-friendly practices, and social advocacy are becoming important aspects of brand identity. 6. Augmented Reality (AR) and Virtual Reality (VR) AR and VR technologies are transforming the way consumers interact with brands. From virtual try-ons to immersive brand experiences, these technologies offer innovative ways to engage customers. As AR and VR become more accessible, marketers should explore how these tools can enhance their campaigns. 7. Privacy and Data Security With increasing concerns about data privacy, marketers must prioritize transparency and compliance with regulations such as GDPR and CCPA. Building trust with consumers through clear data policies and secure data handling practices is essential. Brands that respect user privacy will stand out in a crowded market. 8. Influencer Marketing Evolution Influencer marketing continues to be a powerful strategy, but its landscape is evolving. Micro-influencers and nano-influencers are gaining traction due to their highly engaged and loyal followings. Authenticity and genuine connections are key, as consumers are becoming more discerning about influencer endorsements. 9. Omnichannel Marketing An omnichannel approach ensures a seamless customer experience across multiple touchpoints, including online and offline channels. Integrated marketing strategies that provide consistent messaging and personalized interactions can drive higher engagement and conversions. Brands should focus on creating cohesive journeys that cater to the preferences of their target audience. 10. Blockchain for Digital Advertising Blockchain technology offers potential solutions to some of the challenges faced in digital advertising, such as ad fraud and transparency issues. By providing a decentralized and secure way to verify transactions, blockchain can enhance the credibility and effectiveness of digital ad campaigns. Conclusion The [digital marketing](https://amandigitalswag.in/shantipuram/ ) landscape is rapidly changing, driven by technological advancements and shifting consumer behaviors.

webtesting, webhostingcompany

Web hosting is a fundamental component of the internet, serving as the backbone for websites and online applications. For anyone looking to establish an online presence, understanding web hosting is crucial. This guide will delve into what web hosting is, the types of web hosting available, and how to choose the right web hosting service for your needs. **What is Web Hosting?** **[Web hosting](https://www.riteanswers.com/)** refers to the service that allows individuals and organizations to make their websites accessible via the World Wide Web. Web hosting providers supply the technologies and services needed for a website or webpage to be viewed on the internet. Websites are hosted, or stored, on special computers called servers. When internet users want to view your website, all they need to do is type your website address or domain into their browser. Their computer will then connect to your server and your web pages will be delivered to them through the browser. **Types of Web Hosting** Shared Hosting: This is the most common and affordable type of web hosting. In shared hosting, multiple websites share a single server's resources, including bandwidth, storage, and processing power. It's ideal for small websites and blogs with low to moderate traffic. **VPS Hosting**: Virtual Private Server (VPS) hosting provides a middle ground between shared hosting and dedicated hosting. A VPS hosting environment mimics a dedicated server within a shared hosting environment. It is suitable for websites that have grown beyond the limitations of shared hosting. **Dedicated Hosting**: With dedicated hosting, you get an entire server to yourself. This type of hosting is best for websites with high traffic volumes or those requiring substantial resources. It offers the highest level of performance, security, and control. **Cloud Hosting**: Cloud hosting uses a network of servers to ensure maximum uptime and scalability. This type of hosting is perfect for websites that experience fluctuating traffic levels, as it allows for resources to be allocated dynamically based on demand. **Managed Hosting**: In managed hosting, the hosting provider takes care of all server-related issues, including maintenance, security, and updates. This option is excellent for those who do not have the technical expertise to manage a server or who prefer to focus on their core business activities. Choosing the Right Web Hosting Service When selecting a **[web hosting service](https://www.riteanswers.com/ )**, consider the following factors: **Performance**: Look for hosting services that guarantee high uptime and fast load times. **Security**: Ensure that the hosting provider offers robust security measures, including SSL certificates and regular backups. **Support**: Opt for providers that offer 24/7 customer support to help resolve any issues promptly. **Scalability**: Choose a hosting service that can grow with your website, offering options to upgrade resources as needed. **Cost**: Compare the pricing plans of different providers to find one that offers good value for your specific requirements. Understanding the various aspects of web hosting will enable you to make an informed decision that best suits your website's needs. Whether you're starting a personal blog or running a large e-commerce site, the right web hosting service is critical to your online success.

A node is a **local maxima** if the current node has a value **strictly greater** than the previous node and the next node. A node is a **local minima** if the current node has a value **strictly smaller** than the previous node and the next node. Note that a node can only be a local maxima/minima if there exists **both** a previous node and a next node. Given a linked list `head`, return _an array of length 2 containing `[minDistance, maxDistance]` where `minDistance` is the **minimum distance** between **any two distinct** critical points and `maxDistance` is the **maximum distance** between **any two distinct** critical points. If there are **fewer** than two critical points, return `[-1, -1]`_. **Example 1:**  - **Input:** head = [3,1] - **Output:** [-1,-1] - **Explanation:** There are no critical points in [3,1]. **Example 2:**  - **Input:** head = [5,3,1,2,5,1,2] - **Output:** [1,3] - **Explanation:** There are three critical points: - [5,3,1,2,5,1,2]: The third node is a local minima because 1 is less than 3 and 2. - [5,3,1,2,5,1,2]: The fifth node is a local maxima because 5 is greater than 2 and 1. - [5,3,1,2,5,1,2]: The sixth node is a local minima because 1 is less than 5 and 2. - The minimum distance is between the fifth and the sixth node. minDistance = 6 - 5 = 1. - The maximum distance is between the third and the sixth node. maxDistance = 6 - 3 = 3. **Example 3:**  - **Input:** head = [1,3,2,2,3,2,2,2,7] - **Output:** [3,3] - **Explanation:** There are two critical points: - [1,3,2,2,3,2,2,2,7]: The second node is a local maxima because 3 is greater than 1 and 2. - [1,3,2,2,3,2,2,2,7]: The fifth node is a local maxima because 3 is greater than 2 and 2. - Both the minimum and maximum distances are between the second and the fifth node. - Thus, minDistance and maxDistance is 5 - 2 = 3. - Note that the last node is not considered a local maxima because it does not have a next node. **Constraints:** - The number of nodes in the list is in the range <code>[2, 10⁵]</code>. - <code>1 <= Node.val <= 10⁵</code> **Solution:** ``` /** * Definition for a singly-linked list. * class ListNode { * public $val = 0; * public $next = null; * function __construct($val = 0, $next = null) { * $this->val = $val; * $this->next = $next; * } * } */ class Solution { /** * @param ListNode $head * @return Integer[] */ function nodesBetweenCriticalPoints($head) { $result = [-1, -1]; // Initialize minimum distance to the maximum possible value $minDistance = PHP_INT_MAX; // Pointers to track the previous node, current node, and indices $previousNode = $head; $currentNode = $head->next; $currentIndex = 1; $previousCriticalIndex = 0; $firstCriticalIndex = 0; while ($currentNode->next != null) { // Check if the current node is a local maxima or minima if (($currentNode->val < $previousNode->val && $currentNode->val < $currentNode->next->val) || ($currentNode->val > $previousNode->val && $currentNode->val > $currentNode->next->val)) { // If this is the first critical point found if ($previousCriticalIndex == 0) { $previousCriticalIndex = $currentIndex; $firstCriticalIndex = $currentIndex; } else { // Calculate the minimum distance between critical points $minDistance = min($minDistance, $currentIndex - $previousCriticalIndex); $previousCriticalIndex = $currentIndex; } } // Move to the next node and update indices $currentIndex++; $previousNode = $currentNode; $currentNode = $currentNode->next; } // If at least two critical points were found if ($minDistance != PHP_INT_MAX) { $maxDistance = $previousCriticalIndex - $firstCriticalIndex; $result = [$minDistance, $maxDistance]; } return $result; } } ``` - **[LinkedIn](https://www.linkedin.com/in/arifulhaque/)** - **[GitHub](https://github.com/mah-shamim)**

Have you ever been in the middle of an intense gaming session or an important chat on Discord, only to have your voice sound like a robot or become annoyingly distorted? You're not alone. This issue can be incredibly frustrating, but fortunately, there are several solutions you can try to resolve it. In this article, we'll dive into why this problem occurs and offer practical, easy-to-follow steps to fix it. Plus, we’ll cover some related tips, such as how to use free phone numbers for Discord and free phone numbers for Discord verification, which can come in handy for troubleshooting and enhancing your overall Discord experience. Understanding the Issue: Why Does Your Voice Sound Robotic or Distorted on Discord? Before we jump into the solutions, it’s essential to understand why this problem occurs. A robotic or distorted voice on Discord is typically due to one or more of the following reasons: - Network Issues: Poor internet connection or high latency can disrupt the audio quality. - Hardware Problems: Issues with your microphone or headset. - Software Conflicts: Other applications or settings interfering with Discord. - Server Problems: Issues with the Discord servers or the specific voice channel you’re using. Fixing Network Issues Check Your Internet Connection Your internet connection is the backbone of a smooth Discord experience. Here's what you can do: 1. Speed Test: Run an internet speed test to ensure you have a stable and fast connection. 2. Wired Connection: If possible, use a wired connection instead of Wi-Fi to reduce latency. 3. Restart Router: Sometimes, a simple router restart can resolve temporary connectivity issues. Optimize Discord’s Voice Settings Discord has several settings that can be tweaked to improve voice quality: 1. Open Discord and go to User Settings (cog icon). 2. Select Voice & Video. 3. Under Input Sensitivity, enable Automatically determine input sensitivity. 4. Set the Input Mode to Voice Activity. 5. Adjust the Quality of Service (QoS) setting by disabling Enable Quality of Service High Packet Priority. Addressing Hardware Problems Microphone and Headset Check Ensure your microphone and headset are functioning correctly: 1. Check Connections: Ensure all cables are securely connected. 2. Test with Other Apps: Use your microphone and headset with another application to see if the issue persists. 3. Update Drivers: Make sure your audio drivers are up to date. You can do this through Device Manager on Windows or via your hardware manufacturer’s website. Reduce Background Noise Background noise can cause distortion: 1. Use Noise-Cancelling Features: Many modern headsets come with noise-cancelling features. Enable these if available. 2. Discord Noise Suppression: Enable Krisp, Discord’s built-in noise suppression feature, by going to User Settings > Voice & Video > Advanced and toggling Noise Suppression. Resolving Software Conflicts Close Background Applications Other applications running in the background can interfere with Discord: 1. Close Unnecessary Programs: Use Task Manager (Ctrl + Shift + Esc) to close any unnecessary applications. 2. Check for Conflicts: Ensure no other voice chat applications are running that might conflict with Discord. Update Discord Always use the latest version of Discord: 1. Check for Updates: Discord usually updates automatically, but you can check manually by restarting the app. Adjust Quality of Service Settings QoS settings can sometimes cause issues: 1. Disable QoS: Go to User Settings > Voice & Video > Quality of Service and disable Enable Quality of Service High Packet Priority. Server Problems and Solutions Switch Servers or Regions Sometimes, the issue might be with the Discord server or region you are connected to: 1. Change Server Region: If you are an admin of the server, go to Server Settings > Overview > Server Region and change to a different region. 2. Join a Different Voice Channel: Sometimes, simply switching to another voice channel can resolve the issue. Enhancing Your Discord Experience: Using Free Phone Numbers for Verification Verification is an essential step for securing your Discord account and avoiding spammers. Here’s how to use free phone numbers effectively. Why Use Free Phone Numbers for Discord Verification? Using a temp number for Discord can be beneficial: 1. Privacy: Protect your number. 2. Convenience: Easily get past verification steps without using your real number. How to Get a Temp Phone Number for Discord 1. Online Services: Use services like LegitSMS.com as the best and most reliable provider of free phone numbers for Discord. 2.

PYTHON THE BEAST!

https://dev.to/daphneynep/python-the-beast-24mp

Alright Python is an object-oriented programing language. It makes development of new applications useful for high-level built-in data structures and dynamic typing. Also, it’s useful for scripting or “glue” code to combine existing components written in different languages. Ok as I am diving more into python, learning the modules and doing some of the labs given I am getting nervous because it’s not clicking to me yet! I mean most people says python is their favorite program language. Maybe It could be because it’s “simple and easy to learn syntax emphasizes readability and therefore reduces the cost and complication of long-term program maintenance” (Flatiron School, Intro to Python). Why didn’t I know Python was so difficult? As much as it makes since it’s also confusing at the same time. Sounds crazy right? I just feel like there’s a lot of layers that just keeps coming one after the other as you finish one part, it’s like a mystery. It’s crazy but I really feel challenged to continue learning and having a more understand on how to code with Python. For example, below I am currently stuck on something like this: **# Wrong:** def foo(x): if x >= 0: return math.sqrt(x) def bar(x): if x < 0: return return math.sqrt(x) **# Correct:** def foo(x): if x >= 0: return math.sqrt(x) else: return None def bar(x): if x < 0: return None return math.sqrt(x) When I try to follow the correct way to write my code it doesn’t seem to work. Although What I am working on is a bit different from these codes above but the idea is the same. I’m not sure what I am doing wrong yet but I’ll keep running it again and again until I get it right.

🌀Huracán: El proyecto educativo para ingenieros aprendiendo ZK

Aprender sobre ZK hoy no es una tarea fácil. Es una tecnología nueva, sin mucha documentación....

https://dev.to/turupawn/huracan-el-proyecto-educativo-para-ingenieros-aprendiendo-zk-2dl4

--- title: 🌀Huracán: El proyecto educativo para ingenieros aprendiendo ZK published: true description: tags: # cover_image: https://direct_url_to_image.jpg # Use a ratio of 100:42 for best results. # published_at: 2024-06-26 16:56 +0000 --- Aprender sobre ZK hoy no es una tarea fácil. Es una tecnología nueva, sin mucha documentación. Huracán nace de mi propia necesidad de aprender sobre ZK de una manera práctica, orientada a desarrolladores e ingenieros. Huracán es un proyecto totalmente funcional, capaz de hacer transacciones privadas en Ethereum y blockchains EVM. Está basado en proyectos de privacidad actualmente en funcionamiento, pero con el código mínimo para facilitar el proceso de aprendizaje. Vamos a cubrir cómo esta tecnología puede adaptarse a nuevos casos de uso y futuras regulaciones. Además, al final del artículo comparto qué se necesita para llevar este proyecto de pruebas en testnet a uso real en producción. Al terminar esta guía vas a poder ir a otros proyectos de la misma naturaleza entender cómo están construidos. ¿Prefieres ver el código completo? [Dirígete a Github](https://github.com/Turupawn/Huracan) para encontrar la totalidad del código en esta guíua. _Cómo está construído Huracán:_ * Circuito hecho con Circom * Hasheo con Poseidon * Contratos de lógica de depósito y retiro en solidity * Construcción de merkle trees en js y solidity, verificación en Circom * Frontend con html y js vainilla * web3.js para interacción con web3 y snarkjs para probar en el navegador (zk-WASM) * Relayer con ethers.js 6 y express para preservar el anonimato de los usuarios ## Tabla de contenido 1. [Cómo funciona Huracán](#1-cómo-funciona-huracán) 1. [El circuito](#2-el-circuito) 1. [Los contratos](#3-los-contratos) 1. [El frontend](#4-el-frontend) 1. [El relayer](#5-el-relayer) 1. [¿Cómo llevar Huracán a producción?](#6-cómo-llevar-huracán-a-producción) 1. [Ideas para profundizar](#7-ideas-para-profundizar) ## 1. Cómo funciona Huracán Huracán es una herramienta DeFi que protege la identidad de sus usuarios utilizando la técnica conocida como _pruebas de inclusión anónima_ para realizar lo que comúnmente llamamos _mixer_. Este sistema es capaz de demostrar que un usuario ha depositado ether en un contrato sin demostrar cual de todos fué.  <p><small><em>Cada usuario que deposita Ether en Huracán es colocado como una hoja en un merkle tree dentro del contrato</em></small></p> Para lograr esto, necesitamos un smart contract donde se depositarán los fondos y al hacerlo generará un merkle tree donde cada hoja representa un depositante. Adicionalmente, ocuparemos un circuito que generará las pruebas de inclusión que mantendrán al usuario anónimo al momento de retirar los fondos. Y también un relayer que ejecutará la transacción en nombre del usuario anónimo para proteger su privacidad.  <p><small><em>Los usuarios pueden luego retirar sus fondos demostrando que parte del merkle tree sin revelar cuál hoja les pertenece</em></small></p> A continuación el código, la explicación breve y los materiales de apoyo necesarios para construir y lanzar tu propio proyecto con privacidad. ## 2. El circuito _Material de apoyo: [Smart Contracts privados con Solidity y Circom](https://dev.to/turupawn/smart-contracts-privados-con-solidity-y-circom-3a8h)_ El circuito se encarga si eres parte del merkle tree, es decir, que eres uno de los depositantes sin revelar cuál eres pues mantienes los parámetros privados pero generas una prueba de inclusión que es capaz de ser verificada por un smart contract. ¿Cuáles parámetros privados? Durante el depósito, hasheamos una llave privada y un nulificador para crear así una nueva hoja en el árbol. La llave privada es un parámetro privado que nos servirá para luego demostrar que somos nosotros los dueños de esa hora. El nulificador es otro parámetros cuyo hash será pasado al contrato de solidity al momento de redimir los fondos, esto para prevenir que un usuario retire fondos 2 veces seguidas (double spend). El resto de parámetros privados son la ayuda que ocupa el circuito para reconstruir el árbol y revisar que somos parte de él. Iniciamos instalando la librería `circomlib` que contiene los circuitos de poseidon que estaremos utilizando en este tutorial. ```bash git clone https://github.com/iden3/circomlib.git ``` Ahora creamos nuestro circuito `proveWithdrawal` que prueba que hemos depositado en el contrato sin revelar quién somos. `proveWithdrawal.circom` ```js pragma circom 2.0.0; include "circomlib/circuits/poseidon.circom"; template switchPosition() { signal input in[2]; signal input s; signal output out[2]; s * (1 - s) === 0; out[0] <== (in[1] - in[0])*s + in[0]; out[1] <== (in[0] - in[1])*s + in[1]; } template commitmentHasher() { signal input privateKey; signal input nullifier; signal output commitment; signal output nullifierHash; component commitmentHashComponent; commitmentHashComponent = Poseidon(2); commitmentHashComponent.inputs[0] <== privateKey; commitmentHashComponent.inputs[1] <== nullifier; commitment <== commitmentHashComponent.out; component nullifierHashComponent; nullifierHashComponent = Poseidon(1); nullifierHashComponent.inputs[0] <== nullifier; nullifierHash <== nullifierHashComponent.out; } template proveWithdrawal(levels) { signal input root; signal input recipient; signal input privateKey; signal input nullifier; signal input pathElements[levels]; signal input pathIndices[levels]; signal output nullifierHash; signal leaf; component commitmentHasherComponent; commitmentHasherComponent = commitmentHasher(); commitmentHasherComponent.privateKey <== privateKey; commitmentHasherComponent.nullifier <== nullifier; leaf <== commitmentHasherComponent.commitment; nullifierHash <== commitmentHasherComponent.nullifierHash; component selectors[levels]; component hashers[levels]; signal computedPath[levels]; for (var i = 0; i < levels; i++) { selectors[i] = switchPosition(); selectors[i].in[0] <== i == 0 ? leaf : computedPath[i - 1]; selectors[i].in[1] <== pathElements[i]; selectors[i].s <== pathIndices[i]; hashers[i] = Poseidon(2); hashers[i].inputs[0] <== selectors[i].out[0]; hashers[i].inputs[1] <== selectors[i].out[1]; computedPath[i] <== hashers[i].out; } root === computedPath[levels - 1]; } component main {public [root, recipient]} = proveWithdrawal(2); ``` Para compilar el circuito necesitamos tener instalado ambos circom y snarkjs. Si no lo tienes instalado usa la guía de instalación de Circom. {% collapsible Guía de instalación de Circom %} Coloca estos comandos para instalar circom y snarkjs. ```bash curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh git clone https://github.com/iden3/circom.git cd circom cargo build --release cargo install --path circom npm install -g snarkjs ``` {% endcollapsible %} Ejecuta los comandos para generar la trusted setup y generar los archivos artefactos que estaremos usando más adelante en el frontend. ```bash circom proveWithdrawal.circom --r1cs --wasm --sym snarkjs powersoftau new bn128 12 pot12_0000.ptau -v snarkjs powersoftau contribute pot12_0000.ptau pot12_0001.ptau --name="First contribution" -v snarkjs powersoftau prepare phase2 pot12_0001.ptau pot12_final.ptau -v snarkjs groth16 setup proveWithdrawal.r1cs pot12_final.ptau proveWithdrawal_0000.zkey snarkjs zkey contribute proveWithdrawal_0000.zkey proveWithdrawal_0001.zkey --name="1st Contributor Name" -v snarkjs zkey export verificationkey proveWithdrawal_0001.zkey verification_key.json ``` Ahora podemos generar el contrato verificador en `verfier.sol`. ```bash snarkjs zkey export solidityverifier proveWithdrawal_0001.zkey verifier.sol ``` ## 3. Los contratos _Material de apoyo: [Solidity en 15 minutos](https://dev.to/turupawn/como-lanzar-un-dex-paso-a-pasox-2cnm)_ Los contratos son la garantía transparente que todo ha funcionado de manera correcta. Nos permite llevar un conteo de cuánto se ha depositado y también verifican que las pruebas sean válidas para así liberar los fondos. Es importante que todo lo que ocurre en los smart contracts es público, es la parte de nuestro sistema que no es anónima. Haremos uso de tres contratos. El primero es el contrato verificador que recién generamos en el archivo `verifier.sol`, lánzalo ahora. El segundo contrato es el de poseidon, si estás en Scroll Sepolia simplemente usa el que yo ya lancé en `0x52f28FEC91a076aCc395A8c730dCa6440B6D9519`. Si quieres usar otra blockchain descolapsa y sigue los pasos: {% collapsible Lanza el contrato de poseidon %} La versión de poseidon que usamos en nuestro circuito y contrato deben ser exactamente compatibles. Por lo tanto usamos la versión en `circomlibjs` tal y como lo muestro, solo asegúrate de colocar tu llave privada y url RPC en `TULLAVEPRIVADA` y `TUURLRPC`. ```bash git clone https://github.com/iden3/circomlibjs.git node --input-type=module --eval "import { writeFileSync } from 'fs'; import('./circomlibjs/src/poseidon_gencontract.js').then(({ createCode }) => { const output = createCode(2); writeFileSync('poseidonBytecode', output); })" cast send --rpc-url TUURLRPC --private-key TULLAVEPRIVADA --create $(cat bytecode) ``` {% endcollapsible %} Ahora lanza el contrato `Huracan` pasando como parámetro la dirección del contrato verificador y de poseidon. ```js // SPDX-License-Identifier: MIT pragma solidity >=0.7.0 <0.9.0; interface IPoseidon { function poseidon(uint[2] memory inputs) external returns(uint[1] memory output); } interface ICircomVerifier { function verifyProof(uint[2] calldata _pA, uint[2][2] calldata _pB, uint[2] calldata _pC, uint[3] calldata _pubSignals) external view returns (bool); } contract Huracan { ICircomVerifier circomVerifier; uint nextIndex; uint public constant LEVELS = 2; uint public constant MAX_SIZE = 4; uint public NOTE_VALUE = 0.001 ether; uint[] public filledSubtrees = new uint[](LEVELS); uint[] public emptySubtrees = new uint[](LEVELS); address POSEIDON_ADDRESS; uint public root; mapping(uint => uint) public commitments; mapping(uint => bool) public nullifiers; event Deposit(uint index, uint commitment); constructor(address poseidonAddress, address circomVeriferAddress) { POSEIDON_ADDRESS = poseidonAddress; circomVerifier = ICircomVerifier(circomVeriferAddress); for (uint32 i = 1; i < LEVELS; i++) { emptySubtrees[i] = IPoseidon(POSEIDON_ADDRESS).poseidon([ emptySubtrees[i-1], 0 ])[0]; } } function deposit(uint commitment) public payable { require(msg.value == NOTE_VALUE, "Invalid value sent"); require(nextIndex != MAX_SIZE, "Merkle tree is full. No more leaves can be added"); uint currentIndex = nextIndex; uint currentLevelHash = commitment; uint left; uint right; for (uint32 i = 0; i < LEVELS; i++) { if (currentIndex % 2 == 0) { left = currentLevelHash; right = emptySubtrees[i]; filledSubtrees[i] = currentLevelHash; } else { left = filledSubtrees[i]; right = currentLevelHash; } currentLevelHash = IPoseidon(POSEIDON_ADDRESS).poseidon([left, right])[0]; currentIndex /= 2; } root = currentLevelHash; emit Deposit(nextIndex, commitment); commitments[nextIndex] = commitment; nextIndex = nextIndex + 1; } function withdraw(uint[2] calldata _pA, uint[2][2] calldata _pB, uint[2] calldata _pC, uint[3] calldata _pubSignals) public { circomVerifier.verifyProof(_pA, _pB, _pC, _pubSignals); uint nullifierHash = _pubSignals[0]; uint rootPublicInput = _pubSignals[1]; address recipient = address(uint160(_pubSignals[2])); require(root == rootPublicInput, "Invalid merke root"); require(!nullifiers[nullifierHash], "Vote already casted"); nullifiers[nullifierHash] = true; (bool sent, bytes memory data) = recipient.call{value: NOTE_VALUE}(""); require(sent, "Failed to send Ether"); data; } } ``` ## 4. El frontend _Material de apoyo: [Interfaces con privacidad en Solidity y zk-WASM](https://dev.to/turupawn/interfaces-con-privacidad-en-solidity-y-zk-wasm-1amg)_ El frontend es la interfaz gráfica con la que estaremos interactuando. En esta demostración estaremos usando html y js vainilla para que los desarrolladores podamos adaptarla a cualquier frontend framework que estemos usando. Una característica muy importante del frontend es que debe ser capaz de producir las pruebas zk sin soltar información privada en el internet. Por eso es importante la tecnología zk-WASM que permite de una manera eficiente construir pruebas en nuestro navegador.

Nota: Cambia el nombre de myCircuit_0002.zkey por myCircuit_final.zkey * `index.html`, `js/blockchain_stuff.js` y `js/zk_stuff.js` los detallo a continuación El archivo de HTML contiene la interfaz necesaria para que los usuarios interactén con Huracán. `index.html` ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> </head> <body> <input id="connect_button" type="button" value="Connect" onclick="connectWallet()" style="display: none"></input> <p id="account_address" style="display: none"></p> <p id="web3_message"></p> <p id="contract_state"></p> <input type="input" value="" id="depositPrivateKey" placeholder="private key"></input> <input type="input" value="" id="depositNullifier" placeholder="nullifier"></input> <input type="button" value="Deposit" onclick="_deposit()"></input> <br> <input type="input" value="" id="withdrawPrivateKey" placeholder="private key"></input> <input type="input" value="" id="withdrawNullifier" placeholder="nullifier"></input> <input type="input" value="" id="withdrawRecipient" placeholder="recipient"></input> <input type="button" value="Withdraw" onclick="_withdraw()"></input> <br> <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/web3/1.3.5/web3.min.js"></script> <script type="text/javascript" src="js/zk_stuff.js"></script> <script type="text/javascript" src="js/blockchain_stuff.js"></script> <script type="text/javascript" src="js/snarkjs.min.js"></script> </body> </html> <script> function _deposit() { depositPrivateKey = document.getElementById("depositPrivateKey").value depositNullifier = document.getElementById("depositNullifier").value deposit(depositPrivateKey, depositNullifier) } function _withdraw() { withdrawPrivateKey = document.getElementById("withdrawPrivateKey").value withdrawNullifier = document.getElementById("withdrawNullifier").value withdrawRecipient = document.getElementById("withdrawRecipient").value withdraw(withdrawPrivateKey, withdrawNullifier, withdrawRecipient) } </script> ``` Ahora colocamos toda lo logica relacionada a web3, es decir la conexión a la wallet en el browser, lectura del estado y llamado de funciones. `js/blockchain_stuff.js` ```js const NETWORK_ID = 534351 const HURACAN_ADDRESS = "0x8BD32BDC921f5239c0f5d9eaf093B49A67C3b9d0" const HURACAN_ABI_PATH = "./json_abi/Huracan.json" const POSEIDON_ADDRESS = "0x52f28FEC91a076aCc395A8c730dCa6440B6D9519" const POSEIDON_ABI_PATH = "./json_abi/Poseidon.json" const RELAYER_URL = "http://localhost:8080" var huracanContract var poseidonContract var accounts var web3 let leaves function metamaskReloadCallback() { window.ethereum.on('accountsChanged', (accounts) => { document.getElementById("web3_message").textContent="Se cambió el account, refrescando...";

El relayer ¿De qué sirve usar pruebas de anonimato zk si al final nosotros mismos la ejecutamos? Si hacemos esto perderíamos la privacidad porque en Ethereum todo es público. Por eso ocupamos a un relayer. Un intermediario que ejecuta la transacción on-chain a nombre de del usuario anónimo. Iniciamos creando el archivo del backend. `relayer.mjs` ```js import fs from "fs" import cors from "cors" import express from "express" import { ethers } from 'ethers'; const app = express() app.use(cors()) const JSON_CONTRACT_PATH = "./json_abi/Huracan.json" const CHAIN_ID = "534351" const PORT = 8080 var contract var provider var signer const { RPC_URL, HURACAN_ADDRESS, RELAYER_PRIVATE_KEY, RELAYER_ADDRESS } = process.env; const loadContract = async (data) => { data = JSON.parse(data); contract = new ethers.Contract(HURACAN_ADDRESS, data, signer); } async function initAPI() { provider = new ethers.JsonRpcProvider(RPC_URL); signer = new ethers.Wallet(RELAYER_PRIVATE_KEY, provider); fs.readFile(JSON_CONTRACT_PATH, 'utf8', function (err,data) { if (err) { return console.log(err); } loadContract(data) }); app.listen(PORT, () => { console.log(`Listening to port ${PORT}`) }) } async function relayMessage(pA, pB, pC, publicSignals) { console.log(pA) console.log(pB) console.log(pC) console.log(publicSignals) const transaction = { from: RELAYER_ADDRESS, to: HURACAN_ADDRESS, value: '0', gasPrice: "700000000", // 0.7 gwei nonce: await provider.getTransactionCount(RELAYER_ADDRESS), chainId: CHAIN_ID, data: contract.interface.encodeFunctionData( "withdraw",[pA, pB, pC, publicSignals] ) }; const signedTransaction = await signer.populateTransaction(transaction); const transactionResponse = await signer.sendTransaction(signedTransaction); console.log('🎉 The hash of your transaction is:', transactionResponse.hash); } app.get('/relay', (req, res) => { console.log(req) var pA = req.query["pA"].split(',') var pBTemp = req.query["pB"].split(',') const pB = [ [pBTemp[0], pBTemp[1]], [pBTemp[2], pBTemp[3]] ]; var pC = req.query["pC"].split(',') var publicSignals = req.query["publicSignals"].split(',') relayMessage(pA, pB, pC, publicSignals) res.setHeader('Content-Type', 'application/json'); res.send({ "message": "the proof was relayed" }) }) initAPI() ``` Instala la librería de coors para puedas correr el relayer de manera local. ``` npm install cors ``` Ahora lanza el servidor reemplazando `TUURLRPC`, `TUHURACANADDRESS`, `TULLAVEPRIVADA`, `TUADDRESS` en el comandos a continuación. ```bash RPC_URL=TUURLRPC HURACAN_ADDRESS=TUHURACANADDRESS RELAYER_PRIVATE_KEY=TULLAVEPRIVADA RELAYER_ADDRESS=TUADDRESS node relayer.mjs ``` Ahora estás listo para depositar y retirar fondos en Huracán desde la interfaz web.  ## 6. ¿Cómo llevar Huracán a producción? **a. Guarda el histórico de raíces on-chain** Al solo estar guardando la raíz más reciente, la prueba generada debe usar esta. Esto significa que si justo después de generar una prueba de retiro alguien hace un depósito, y por consiguiente modifica la raíz, la prueba generada será inválida y se tendrá que generar una nueva. _Cambios necesarios:_ Guardar todo el histórico de las raíces on chain en, por ejemplo un mapping `mapping(uint id => uint root) public roots;` y al momento de generar una prueba usar la más reciente. Si alguien hace un depósito y cambia la raíz no habrá problema pues la verificación se hará ente cualquier raíz que haya sido guardada históricamente usando una función, por ejemplo `isKnownRoot(uint root)`. **b. Indexa el merkle tree en un lugar accesible** Para generar una prueba de inclusión, ocupamos leer el estado actual del árbol. Actualmente lo leemos de la variable `commitments` pero este proceso es lento y requiere muchas llamadas RPC si el tamaño del árbol es grande. _Cambios necesarios:_ Almacenar e indexar en un lugar accesible la totalidad del árbol. Pienso que el lugar ideal para esto es un subgraph. **c. Incentiva al relayer** Es necesario ofrecer una recompensa al relayer pues él es quien paga las comisiones de transacción on-chain. _Cambios necesarios:_ Al momento de generar la prueba, otorga un porcentaje de la note al relayer. Puedes hacer esto agregándo un parámetro extra en los circuitos, por ejemplo `signal input fee;` y en solidity enviar ese valor al `msg.sender` o a quien el relayer determine. **d. Usa librerías adecuadas** En la webapp, en vez de html y js vainilla deberías usar un frontend framework como react, angular o vue para ofrecer una mejor experiencia a los usuarios y desarrolladores. En el relayer, en vez de express se debería de usar un backend más robusto y hostearlo en una máquina equipada para soportar un número de transacciones alto y con mecanismos anti-DoS, con un firewall adecuado ya que los fondos del relayer para usar como gas son un motivo para hackear el servidor. **e. Define el tamaño del merkle tree** Este ejemplo funciona para 4 depositantes, tendrás que reflejar los cambios en el circuito y contrato para hacerlo funcionar. _Cambios necesarios:_ Comienza cámbiando [la cantidad de niveles en el circuito](https://github.com/Turupawn/Huracan/blob/master/circuits/proveWithdrawal.circom#L67) actualmente está establecida en 2 pues es la cantidad necesaria para un árbol con 4 hojas. Además actualiza las constantes `LEVELS` y `MAX_SIZE` [en el contrato](https://github.com/Turupawn/Huracan/blob/master/contracts/Huracan.sol#L16). Si tu árbol es muy grande, puedes ahorrar gas en el lanzamiento hardcodeando los valores default de un árbol vacío [en vez de usar un ciclo](https://github.com/Turupawn/Huracan/blob/master/contracts/Huracan.sol#L33) como lo he mostrado. **f. Recuerda, muy importante, todo lo que hemos usado está en etapas experimentales** Los circuitos y contratos en esta guía no están debidamente auditados, al igual que las librerías que se usan. Como por ejemplo Poseidon, que es una nueva función de hasheo que es muy prometedora y que usamos en vez del tradicional Pedersen. Y también recuerda, en este tutorial no hemos hecho una trusted setup segura. Para hacer esto es recomendado hacer una ceremonia abierta, con tiempo suficiente para abrir la participación. ## 7. Ideas para profundizar **a. Pruebas de exclusión** De la misma manera que en este ejemplo manejamos pruebas de inclusión, podemos hacer pruebas de exclusión que _demuestren que que no somos parte de un grupo blacklisteado_. Esto puede ayudar a ser compatibles con futuras regulaciones que determinen los estados. **b. Usar ERC20s en vez de Ether** En vez de usar la ether como moneda nativa en Solidity, podemos usar un ERC20 específico. Los cambios únicamente se harán en los contratos de solidity y webapp. Pues los circuitos pueden quedar exactamente igual. **c. Experimentar con Re-staking** Una vez integres ERC20s me parece que una buen paso para continuar es experimentar con la generación de ganancias pasivas usando LSTs. **d. ¡Piensa en otros casos de uso!** Las pruebas de inclusión anónimas tienen muchos casos de uso, inclusive fuera de DeFi. Piensa cómo puedes implementar lo que has aprendido en sistemas de votos y gobernanza, redes sociales, videojuegos, etc... **¡Gracias por leer esta guía!** Sígueme en dev.to y en [Youtube](https://www.youtube.com/channel/UCNRB4tgwp09z4391JRjEsRA) para todo lo relacionado al desarrollo en Blockchain en Español.

strapi, nextjs, webdev, beginners

It is true that maintaining a healthy diet can be a challenge especially because we often find ourselves short on time, unsure about what to eat, or struggling to track our nutritional intake. A nutrition planning app can be a valuable tool in overcoming these issues. This guide will walk you through the process of building a nutrition planning app using Strapi, a user-friendly headless content management system (CMS), and Next.js, a powerful framework for building modern web applications. With these technologies, you can create a personalized app that helps you achieve your dietary goals. This guide is designed for individuals with a basic understanding of web development concepts. We will provide clear explanations and step-by-step instructions, making the process accessible even for those new to Strapi and Next.js. **Prerequisites** To begin with, there are a few essential tools you'll need to have installed on your system. 1. Node.js and npm (or yarn) Installing Node.js and npm (or yarn) Both Node.js and npm (or yarn) are typically installed together as part of the Node.js download. Here's how to get them set up on your system: * Download Node.js: Head over to the official Node.js website: https://nodejs.org/en/download Choose the appropriate installer for your operating system (Windows, macOS, or Linux).  * Install Node.js: Follow the on-screen instructions during the installation process. In most cases, the default settings will be sufficient. * Verify Installation: Once the installation is complete, open your terminal or command prompt. Type the following commands and press Enter after each: ``` bash node -v npm -v ``` These commands should display the installed versions of Node.js and npm, confirming successful installation. **Alternatively, using yarn:** If you prefer using yarn as your package manager, you can install it globally after installing Node.js: ``` bash npm install -g yarn ``` Then, verify the installation by running: ``` bash yarn --version ``` By following these steps, you'll have Node.js, npm, and optionally yarn ready to use for building your nutrition planning app and other JavaScript projects. 2. Creating a Next.js project using create-next-app command Now that you have Node.js and npm (or yarn) set up, let's create the foundation for your nutrition planning app using Next.js. Here's how to do it with the `create-next-app` command: * Open your terminal or command prompt. * Navigate to the directory where you want to create your project. You can use the `cd` command to change directories. For example: ```bash cd Documents/MyProjects ``` * Run the following command to create a new Next.js project: ```bash npx create-next-app@latest my-nutrition-app ``` * `npx`: This is a tool included with npm that allows you to execute packages without installing them globally. * `create-next-app@latest`: This is the command that initiates the project creation process. You can also specify a specific version of `create-next-app` if needed, but `@latest` ensures you're using the most recent stable version. * `my-nutrition-app`: Replace this with your desired project name. * Press Enter.  The `create-next-app` command will download the necessary dependencies and set up the basic project structure for your Next.js application. This process might take a few moments. Once finished, you'll see a success message in your terminal indicating that your project has been created.  ## Initializing the Strapi project: Navigate to the root directory of your Next.js project (cd my-nutrition-app). Use `npx create-strapi-app@latest strapi-api`. This creates a Strapi API project named **strapi-api** within your Next.js project.  In the case of Strapi, when you initialize a new project using `npx create-strapi-app@latest strapi-api`, the Strapi CLI takes care of installing the necessary dependencies for you. This includes the core Strapi framework, database drivers (if applicable), and other packages required for Strapi to function. So, you typically **don't need to manually install dependencies** after initialization. The `npm install` command is usually run during the initialization process itself. Here's what happens during initialization: 1. **Downloads Packages:** The Strapi CLI downloads the required packages from the npm registry and installs them in your Strapi project's `node_modules` directory. 2. **Configures Project:** The CLI configures your project based on your choices during initialization (e.g., database type). This involves setting up configuration files. The address displayed after initialization (`http://localhost:1337/admin` by default) indicates that Strapi has started successfully and the admin panel is accessible. This confirms that the dependencies were installed and configured correctly. **Exceptions:** - **Custom Dependencies:** If you plan to use additional functionalities beyond the core Strapi features, you might need to install specific npm packages for those features within your Strapi project. - **Manual Installation:** If you encounter issues during initialization or prefer a more manual approach, you can install Strapi globally using `npx create-strapi-app@latest my-project ` and then create your project using `strapi new strapi-api`. However, this global installation is generally not recommended for managing individual project dependencies. You can access the Strapi admin panel at http://localhost:1337/admin. ## Getting Started with Strapi When you start a Strapi server, you'll see a login page because Strapi provides an admin panel for managing your content and configurations. This is a secure way to access and modify your Strapi data.  **Login with your credentials:** If you haven't set up any user accounts yet, you'll likely find default credentials in the Strapi documentation or project setup instructions. These default credentials are usually for initial setup purposes and should be changed for security reasons. Quick Start Guide: https://docs.strapi.io/dev-docs/quick-start Installation: https://docs.strapi.io/dev-docs/installation Setup and Deployment: https://docs.strapi.io/dev-docs/quick-start You can refeer to these documentations to guide you with setting up Strapi ## Defining Strapi Content Types for Your Nutrition App Strapi uses content types, also known as models, to define the structure of your data. These models will represent the different entities in your nutrition planning app. Here's how we'll set them up for our project: 1. **Navigate to your Strapi project directory:** Use the `cd` command in your terminal to change directories, for example: ```bash cd my-strapi-api ``` 2. **Start the Strapi development server:** ```bash strapi develop ``` This command will launch the Strapi admin panel in your web browser, typically accessible at http://localhost:1337/. 3. **Access the Content-Type Builder:** In the Strapi admin panel, navigate to the **Content-Type Builder** section (usually found in the left sidebar).  4. **Create each content type:** * Click on **"Create a new collection/single type"**.  * Choose whether it's a **Collection Type** (for Users, Foods, Meals) or a **Single Type** (for Daily Plans) based on the model description above. * Define the name and attributes for each content type, matching the ones listed previously. * Save the content type after adding attributes. ## Creating Content Types in Strapi for your Nutrition App Here's a guide on creating the content types you mentioned for your Personalized Nutrition Planning App in Strapi: We'll create each content type (Food, Meal, Plan) one by one: **a. User:** - Attributes: - Username (Text, unique) - Email (Email, unique) - Password (Password) - **(Optional for personalization):** - Age (Number) - Weight (Number) - Height (Number) - Activity Level (Text options: Sedentary, Lightly Active, Moderately Active, Very Active) - Dietary Restrictions (Text or JSON format for multiple restrictions) - Goals (Text or JSON format for multiple goals: Weight Loss, Muscle Gain, Maintain Weight Strapi comes with a pre-built "User" content type by default. This is a common approach in content management systems (CMS) like Strapi. Since you already see the User content type in your Strapi admin panel, you don't need to create one from scratch as we will be utilizing the default user content type **b. Food:** 1. Go to the **Collection types** sub-navigation. 2. Click on **Create a new collection type**. 3. In the **Display name** field, enter "Food". 4. Leave the **API ID (singular)** and **API ID (plural)** pre-filled values (usually "food" and "foods"). 5. Now, define the attributes for Food: * Click **Add another field**. * In the **Name** field, enter "Name". * Select **Short Text** as the data type. * Repeat for the following attributes with their corresponding data types: * Description (Text) * Calories (Number) * Protein (Number) * Carbs (Number) * Fat (Number) * For **Micronutrients**, create a new field with: * Name: "Micronutrients" * Data type: **JSON**. (This allows storing various micronutrient values as a key-value pair) * For **Image**, create a new field with: * Name: "Image" * Data type: **Media**. (This allows uploading an image for the food item)  **c. Meal:** 1. Go to the **Collection types** sub-navigation. 2. Click on **Create a new collection type**. 3. In the **Display name** field, enter "Meal". 4. Leave the **API ID (singular)** and **API ID (plural)** pre-filled values (usually "meal" and "meals"). 5. Define the attributes for Meal: * Name (Text) * Description (Text) (optional) * Foods (Relation): * Click **Add another field**. * Name: "Foods" * Data type: **Relation**. * Select "foods" (the Food collection type) in the **Target collection** dropdown. (This allows linking multiple food items to a meal) * Total Calories (Number) (This will be a calculated field based on associated foods, we'll configure this later) * Total Macronutrients (Number) (This will also be calculated based on associated foods) **d. Plan:** 1. Go to the **Collection types** sub-navigation. 2. Click on **Create a new collection type**. 3. In the **Display name** field, enter "Plan". 4. Leave the **API ID (singular)** and **API ID (plural)** pre-filled values (usually "plan" and "plans"). 5. Define the attributes for Plan: * User (Relation): * Click **Add another field**. * Name: "User" * Data type: **Relation**. * Select "users" (assuming you have a User collection type) in the **Target collection** dropdown. (This links a plan to a specific user) * Name (Text) * Description (Text) (optional) * Start Date (Date) * End Date (Date) (optional) * Meals (Relation): * Click **Add another field**. * Name: "Meals" * Data type: **Relation**. * Select "meals" (the Meal collection type) in the **Target collection** dropdown. (This allows linking multiple meals to a plan) * Total Daily Calories (Number) (This will be a calculated field based on associated meals, we'll configure this later) * Total Daily Macronutrients (Number) (This will also be calculated based on associated meals) * **Optional for personalization:** * Target Daily Calories (Number) * Target Daily Macronutrient Ratios (JSON): This can be another field with JSON data type to define percentages for protein, carbs, and fat. **. Saving and Defining Relations:** * Once you've defined all the attributes for each content type, click **Save**. * Strapi will create the content types with the specified attributes. **Personalization Considerations:** - The "User" content type captures information that allows for personalized recommendations. Utilize the optional fields to gather details about a user's activity level, dietary restrictions, and goals. - When creating "Meals" and "Plans," consider allowing users to create custom meals and plans. You can also pre-populate some plans with sample meals based on different dietary needs or goals. - The "Plan" content type's optional fields (Target Daily Calories and Macronutrient Ratios) enable you to calculate these values based on the user's profile and goals, creating a personalized meal plan. **Note:** - You can further customize these content types based on your specific app features. - Explore Strapi's documentation ([https://docs.strapi.io/](https://docs.strapi.io/)) for detailed explanations of attribute types and functionalities. ## Strapi API Development: Connecting Next.js to Your Strapi Backend Now that you have Strapi set up with the necessary content types, let's connect your Next.js frontend to this powerful API. Here's what we need to do: **1. Setting Up Environment Variables for Strapi URL:** To access your Strapi API from Next.js, you'll need to store the Strapi URL as an environment variable. This keeps your API endpoint configuration separate from your code and allows for easy management. There are two main approaches to setting environment variables: * **.env File:** This is a common approach for development environments. Create a file named `.env.local` in the root directory of your Next.js project (**my-nutrition-app**). Inside this file, define a variable named `STRAPI_URL` with the value of your Strapi API endpoint URL. For example: ```bash STRAPI_URL=http://localhost:1337 # Assuming Strapi runs on localhost ``` **Important:** Remember to **exclude the .env file from version control** (e.g., Git) to avoid storing sensitive API URLs publicly. * **System Environment Variables:** This approach is more suitable for production environments. You can set environment variables directly on your server or hosting platform. Consult the documentation for your specific hosting provider for instructions on setting environment variables. ## Connecting Next.js to Strapi API Once you have the Strapi URL stored as an environment variable, you can use it within your Next.js components to fetch data from your Strapi API. Here are two common methods: * **`getStaticProps`:** This function is used for pre-rendering data at build time. It's ideal for static pages that don't require frequent updates. ```javascript // Example: Fetching all foods in a component export async function getStaticProps() { const response = await fetch(`${process.env.NEXT_PUBLIC_STRAPI_URL}/foods`); const foods = await response.json(); return { props: { foods }, }; } function MyComponent({ foods }) { // Use the fetched foods data in your component } ``` * **`getServerSideProps`:** This function fetches data on every request to the server. It's useful for dynamic pages that require up-to-date information. ```javascript // Example: Fetching daily plans for a specific user export async function getServerSideProps(context) { const userId = context.params.userId; const response = await fetch(`${process.env.NEXT_PUBLIC_STRAPI_URL}/daily-plans?user=${userId}`); const dailyPlans = await response.json(); return { props: { dailyPlans }, }; } function MyComponent({ dailyPlans }) { // Use the fetched daily plans data in your component } ``` The choice between `getStaticProps` and `getServerSideProps` depends on your specific needs. Use `getStaticProps` for static content that doesn't change frequently. If you require dynamic updates based on user interaction or other factors, `getServerSideProps` is a better option. For the sake of this tutorial, let's use `getStaticProps` to keep things simpler and focus on the core concepts. ## User Authentication (Optional): Integrating Strapi and Next.js While user accounts aren't essential for a basic nutrition planning app, they can unlock features like personalized meal plans and progress tracking. This section explores implementing user authentication with Strapi and Next.js (optional). **1. Setting Up Strapi User Accounts:** If you choose to include user accounts, you'll need to enable the Users & Permissions plugin in Strapi: * In the Strapi admin panel, navigate to **Settings** > **Plugins**. * Find the **Users & Permissions** plugin and click **Install**. This plugin provides user registration, login functionalities, and JWT (JSON Web Token) based authentication. You'll need to define the User model within Strapi, including attributes like username, email, and password. **2. Implementing User Registration and Login in Next.js:** Strapi's user functionalities are exposed through API endpoints. You'll use Next.js components and libraries like Axios to interact with these endpoints: * **Registration:** Create a form component that captures user information (username, email, password) and sends a POST request to the Strapi `/auth/local/register` endpoint. * **Login:** Implement a login form that sends user credentials (email, password) to the Strapi `/auth/local` endpoint for authentication. Upon successful login, Strapi will return a JWT token. **3. Storing JWT Tokens in Next.js:** Once you receive the JWT token from Strapi upon login, you'll need to store it securely in Next.js. Here are two common approaches: * **Local Storage:** You can store the JWT token in the user's browser local storage. This is a convenient option for simple scenarios but has security limitations (tokens are accessible to JavaScript code). * **Cookies (HttpOnly Flag):** Setting the HttpOnly flag on a cookie prevents JavaScript from accessing it directly, offering better security for storing JWT tokens. However, this approach requires additional configuration in your Next.js app. **4. Protecting Routes with Authorization:** To protect specific routes or functionalities in your app that require user authentication, you can implement authorization checks using the stored JWT token. This involves checking if a valid token exists before rendering protected components or fetching sensitive data. Libraries like `next-auth/jwt` can simplify JWT authentication management in Next.js. **Important Note:** This section provides a high-level overview of user authentication. Implementing secure and robust authentication is a complex topic. Refer to the Strapi documentation and Next.js resources for more detailed instructions and best practices: * Strapi User & Permissions Plugin: [https://strapi.io/blog/a-beginners-guide-to-authentication-and-authorization-in-strapi](https://strapi.io/blog/a-beginners-guide-to-authentication-and-authorization-in-strapi) * NextAuth.js library: [https://next-auth.js.org/](https://next-auth.js.org/) **Remember:** If you choose not to implement user accounts, you can skip this section and proceed to building the core functionalities of your nutrition planning app. ## Building the Next.js Frontend: Reusable Components Now that you have the data flowing from Strapi to your Next.js application, let's focus on building the user interface using reusable components. Here's how to create some essential components for your nutrition planning app: **1. Layouts (header, footer, navigation):** These components will provide a consistent structure across all your app pages. * Create a directory named `components` in your Next.js project's root directory (`my-nutrition-app/components`). * Inside `components`, create a file named `Layout.js`. This will be your main layout component. ```javascript // components/Layout.js import React from 'react'; function Layout({ children }) { return ( <div className="container"> <header> <h1>My Nutrition Planner</h1> {/* Navigation links can be added here */} </header> <main>{children}</main> <footer>© Your Name or Company 2024</footer> </div> ); } export default Layout; ``` * You can create separate components for specific navigation elements within the `Layout` component if needed. **2. Food Cards (displaying food information):** These components will display individual food items with details like name, calories, and macros. * Create a file named `FoodCard.js` inside the `components` directory. ```javascript // components/FoodCard.js import React from 'react'; function FoodCard({ food }) { return ( <div className="food-card"> <h3>{food.name}</h3> <p>{food.calories} kcal</p> <p>Carbs: {food.carbs}g Protein: {food.protein}g Fat: {food.fat}g</p> {/* Add button or link for adding food to a meal plan (optional) */} </div> ); } export default FoodCard; ``` **3. Meal Sections (breakfast, lunch, etc.):** These components will represent individual meals within a daily plan, potentially containing a list of associated food cards. * Create a file named `MealSection.js` inside the `components` directory. ```javascript // components/MealSection.js import React from 'react'; import FoodCard from './FoodCard'; // Import the FoodCard component function MealSection({ title, foods }) { return ( <section className="meal-section"> <h2>{title}</h2> <ul> {foods.map((food) => ( <li key={food.id}> <FoodCard food={food} /> </li> ))} </ul> </section> ); } export default MealSection; ``` **4. Daily Plan Overview:** This component will display the overall structure of a daily plan, potentially including meal sections and functionalities for adding/removing foods. * Create a file named `DailyPlan.js` inside the `components` directory. ```javascript // components/DailyPlan.js import React, { useState } from 'react'; import MealSection from './MealSection'; // Import the MealSection component function DailyPlan({ plan }) { const [selectedFoods, setSelectedFoods] = useState([]); // State for selected foods // Functions for adding/removing foods from the plan (implementation details omitted) return ( <div className="daily-plan"> <h2>Daily Plan</h2> {/* Display date or other relevant information about the plan */} {plan.meals.map((meal) => ( <MealSection key={meal.id} title={meal.name} foods={selectedFoods.filter((food) => food.mealId === meal.id)} /> ))} {/* Buttons or functionalities for adding/removing foods and managing the plan */} </div> ); } export default DailyPlan; ``` **Explanation:** * These are basic examples, and you can customize them further with styling (CSS) and additional functionalities like user interactions for managing meal plans. * Notice how we import and utilize the previously created components (`FoodCard` and `MealSection`) within these components, promoting reusability. ## Data Display and Management in Your Nutrition App Now that you have the reusable components and data flowing from Strapi, let's explore how to display information and implement functionalities in your Next.js app. **1. Populating Components with Fetched Data:** We'll use the data fetched from Strapi using `getStaticProps` or potentially `getServerSideProps` (depending on your chosen approach) to populate your components. Here's an example: * In a page component (e.g., `pages/plans/index.js`), you can fetch daily plans and then use the data within your `DailyPlan` component: ```javascript // pages/plans/index.js import { getStaticProps } from 'next'; import DailyPlan from '../../components/DailyPlan'; // Import the DailyPlan component export async function getStaticProps() { // Fetch daily plans data from Strapi const response = await fetch(`${process.env.NEXT_PUBLIC_STRAPI_URL}/daily-plans`); const dailyPlans = await response.json(); return { props: { dailyPlans }, }; } function PlansPage({ dailyPlans }) { return ( <div> <h1>My Daily Plans</h1> {dailyPlans.map((plan) => ( <DailyPlan key={plan.id} plan={plan} /> ))} </div> ); } export default PlansPage; ``` * Within the `DailyPlan` component, you can access the `plan` prop containing the fetched data and use it to display details and associated meals with `MealSection` components. **2. Adding/Removing Foods from Meals (Optional):** This functionality requires managing the state of selected foods within a meal plan. Here's a basic example: * In the `DailyPlan` component, you can introduce state for selected foods using `useState`: ```javascript function DailyPlan({ plan }) { const [selectedFoods, setSelectedFoods] = useState([]); // State for selected foods const handleAddFood = (food) => { setSelectedFoods([...selectedFoods, food]); // Add food to selected list }; const handleRemoveFood = (foodId) => { setSelectedFoods(selectedFoods.filter((food) => food.id !== foodId)); // Remove food from list }; // ... (rest of the component) } ``` * You can then pass these functions and the `selectedFoods` state as props to the `MealSection` component, allowing it to display the selected foods and potentially offer functionalities for adding/removing them based on user interaction. **3. Creating/Editing Daily Plans:** * This functionality involves creating forms or interfaces for users to add new daily plans and potentially edit existing ones. * You'll need to implement form handling and logic to send data (new plan details) to your Strapi API for creation. Libraries like `Formik` or `React Hook Form` can simplify form management. * Editing plans might involve fetching a specific plan's details, pre-populating a form with existing data, and sending updates back to Strapi upon user submission. ```js// pages/plans/edit.js import React, { useState, useEffect } from 'react'; import axios from 'axios'; // Assuming using Axios for API calls import { useRouter } from 'next/router'; // For routing after update function EditPlanPage({ planId }) { const router = useRouter(); const [date, setDate] = useState(''); // State for plan date // Fetch plan details on initial render useEffect(() => { const fetchData = async () => { try { const response = await axios.get(`${process.env.NEXT_PUBLIC_STRAPI_URL}/daily-plans/${planId}`); const plan = response.data; setDate(plan.date); // Set fetched date } catch (error) { console.error('Error fetching plan:', error); // Handle errors (e.g., redirect to error page) } }; fetchData(); }, [planId]); // Fetch data only on planId change const handleSubmit = async (event) => { event.preventDefault(); const updatedPlan = { date, }; try { const response = await axios.put(`${process.env.NEXT_PUBLIC_STRAPI_URL}/daily-plans/${planId}`, updatedPlan); console.log('Plan updated successfully:', response.data); router.push('/plans'); // Redirect to plan list after successful update } catch (error) { console.error('Error updating plan:', error); // Handle errors appropriately (e.g., display error message) } }; return ( <div> <h1>Edit Daily Plan</h1> <form onSubmit={handleSubmit}> <label htmlFor="date">Date:</label> <input type="date" id="date" value={date} onChange={(e) => setDate(e.target.value)} /> <button type="submit">Update Plan</button> </form> </div> ); } export async function getServerSideProps(context) { const { planId } = context.params; return { props: { planId, }, }; } export default EditPlanPage; ``` **4. Tracking Nutritional Goals (Optional):** * This feature requires additional functionalities. You might need to: * Define nutritional goals (calories, macros) for users. * Calculate and display total nutrient intake based on selected foods within a meal plan. * Potentially store and visualize progress over time. ```js // components/DailyPlan.js (modified) import React, { useState } from 'react'; import MealSection from './MealSection'; // Import the MealSection component function DailyPlan({ plan, foods }) { const [selectedFoods, setSelectedFoods] = useState([]); // State for selected foods const handleAddFood = (food) => { setSelectedFoods([...selectedFoods, food]); // Add food to selected list }; const handleRemoveFood = (foodId) => { setSelectedFoods(selectedFoods.filter((food) => food.id !== foodId)); // Remove food from list }; const calculateTotalNutrients = () => { let totalCalories = 0; let totalCarbs = 0; let totalProtein = 0; let totalFat = 0; selectedFoods.forEach((food) => { totalCalories += food.calories; totalCarbs += food.carbs; totalProtein += food.protein; totalFat += food.fat; }); return { calories: totalCalories, carbs: totalCarbs, protein: totalProtein, fat: totalFat }; }; const nutrients = calculateTotalNutrients(); return ( <div className="daily-plan"> <h2>Daily Plan - {plan.date}</h2> {/* Display other plan details (optional) */} {plan.meals.map((meal) => ( <MealSection key={meal.id} title={meal.name} foods={selectedFoods.filter((food) => food.mealId === meal.id)} onAddFood={handleAddFood} onRemoveFood={handleRemoveFood} /> ))} {/* Buttons or functionalities for adding/removing foods and managing the plan */} <div className="nutrient-summary"> <h3>Nutrient Summary</h3> <p>Calories: {nutrients.calories} kcal</p> <p>Carbs: {nutrients.carbs}g ``` **Note:** * These are simplified examples, and you'll need to implement the logic for data manipulation, user interactions, and API calls based on your specific requirements. * Consider using state management libraries like Redux or Zustand for managing complex application state across components. ## Integrating with External Food Databases (USDA) While Strapi can manage your own custom food data, you can also leverage external food databases like the USDA FoodData Central API ([https://www.ers.usda.gov/developer/data-apis/](https://www.ers.usda.gov/developer/data-apis/)) to enrich your app's functionality. Here's an approach to integrate with the USDA API: **1. USDA FoodData Central API:** The USDA FoodData Central API provides a vast dataset of standardized food information, including nutrients, descriptions, and standard units. **2. API Access and Calls:** * You'll need to register for an API key from the USDA website ([https://www.ers.usda.gov/developer/data-apis/](https://www.ers.usda.gov/developer/data-apis/)). * The USDA API uses a RESTful architecture, allowing you to make HTTP requests to retrieve data based on your needs. **3. Example Code (using Axios):** ```javascript import axios from 'axios'; const USDA_API_URL = 'https://fdc.nal.usda.gov/api/foods'; // Base URL for USDA API const YOUR_API_KEY = 'YOUR_USDA_API_KEY'; // Replace with your actual API key async function searchUSDAFoods(searchTerm) { const params = { api_key: YOUR_API_KEY, q: searchTerm, sort: 'n:asc', // Sort by name ascending (optional) pageSize: 10, // Limit results per page (optional) }; try { const response = await axios.get(USDA_API_URL, { params }); const foods = response.data.foods; return foods; } catch (error) { console.error('Error fetching USDA foods:', error); // Handle errors appropriately (e.g., display an error message) return []; } } // Example usage: const searchTerm = 'apple'; searchUSDAFoods(searchTerm).then((foods) => { console.log('USDA Foods search results:', foods); // Use the fetched food data (e.g., display search results) }); ``` * This code defines the USDA API URL and utilizes your API key. * The `searchUSDAFoods` function takes a search term and builds the API request parameters. * It retrieves food data based on the search term and returns an array of results. * Remember to replace `YOUR_USDA_API_KEY` with your actual key. **Important Considerations:** * The USDA API has usage limits and terms of service. Ensure you comply with their guidelines. * Consider implementing search debouncing to avoid overwhelming the API with excessive requests. * You might need additional logic to handle potential discrepancies between your Strapi food data and the USDA data (e.g., matching based on identifiers or names). ## Implementing a Meal Suggestion Engine Enhancing your nutrition planning app with a meal suggestion engine based on user preferences and goals can significantly improve its value proposition. Here's a breakdown of the steps involved: **1. User Preferences and Goals:** * Collect user data regarding dietary restrictions (vegetarian, vegan, etc.), allergies, and food preferences (dislikes, favorite cuisines). * Allow users to set goals like weight management (calories) or targeted nutrient intake (protein, carbs, fat). ```js // components/UserProfile.js import React, { useState } from 'react'; function UserProfile() { const [preferences, setPreferences] = useState({ dietaryRestrictions: [], // List of dietary restrictions (vegetarian, vegan, etc.) allergies: [], // List of allergies dislikes: [], // List of disliked foods favoriteCuisines: [], // List of favorite cuisines }); const [goals, setGoals] = useState({ calories: null, // Daily calorie target macros: { protein: null, // Target protein intake carbs: null, // Target carbs intake fat: null, // Target fat intake }, }); // Handle user input for preferences and goals (form fields or selection components) return ( <div> <h2>User Profile</h2> {/* Form or components to capture user preferences and goals */} </div> ); } export default UserProfile; ``` **2. Food Data Integration:** * Utilize your existing Strapi food data and potentially integrate with external databases like USDA (as discussed previously). ``` js // utils/foodData.js import axios from 'axios'; const USDA_API_URL = 'https://fdc.nal.usda.gov/api/foods'; // Base URL for USDA API async function fetchStrapiFoods() { const response = await fetch(`${process.env.NEXT_PUBLIC_STRAPI_URL}/foods`); return response.json(); } async function searchUSDAFoods(searchTerm) { const params = { api_key: YOUR_USDA_API_KEY, q: searchTerm, }; try { const response = await axios.get(USDA_API_URL, { params }); return response.data.foods; } catch (error) { console.error('Error fetching USDA foods:', error); return []; } } export { fetchStrapiFoods, searchUSDAFoods }; ``` This code defines functions for fetching both Strapi food data and searching the USDA API (replace YOUR_USDA_API_KEY with your actual key). * Ensure your food data includes relevant information like calories, macronutrients (carbs, protein, fat), and potentially micronutrients (vitamins, minerals). **3. Meal Planning Algorithm:** The core of your suggestion engine is a logic that recommends meals based on user preferences and goals: - **Filter Foods:** Based on user preferences, filter out foods that don't fit their dietary restrictions or allergies. ```js function filterFoods(foods, userPreferences) { return foods.filter((food) => { // Check if food aligns with dietary restrictions, allergies, and dislikes const restrictionsMet = !userPreferences.dietaryRestrictions.includes(food.dietaryRestriction); const noAllergens = !userPreferences.allergies.some((allergen) => food.allergens.includes(allergen)); const notDisliked = !userPreferences.dislikes.includes(food.name); return restrictionsMet && noAllergens && notDisliked; }); } ``` This function filters the food data based on user preferences. - **Prioritize Based on Goals:** If the user has set goals (e.g., calorie deficit for weight loss), prioritize foods that align with those goals. You can implement scoring mechanisms based on calorie/nutrient content. ```js function prioritizeFoods(foods, goals) { // Implement logic based on your goal criteria (e.g., calorie deficit) // Here's a simplified example prioritizing lower calorie foods: return foods.sort((food1, food2) => food1.calories - food2.calories); } ``` - **Meal Composition:** Consider building balanced meals with appropriate proportions of macronutrients (e.g., balanced protein, carbs, and fat for most meals). - - **Variety:** Introduce variety by suggesting different food options within a meal category while still adhering to preferences and goals. ```js function suggestMeal(filteredFoods, goals) { const meal = []; let remainingCalories = goals.calories; // Track remaining calories for balanced meal // Iterate through food categories (protein, carbs, fat) for (const category of ['protein', 'carbs', 'fat']) { const categoryFoods = filteredFoods.filter((food) => food.category === category); // Select a food prioritizing lower calorie options while considering variety const selectedFood = prioritizeFoods(categoryFoods, goals)[0]; if (selectedFood && selectedFood.calories <= remainingCalories) { meal.push(selectedFood); remainingCalories -= selectedFood.calories; } } return meal; } ``` This function suggests a balanced meal with variety, considering remaining calorie budget from user goals. **Code Snippet (Simplified Example):** ```javascript function suggestMeals(userPreferences, goals, foods) { // Filter foods based on user preferences (restrictions, allergies) const filteredFoods = foods.filter((food) => { // Implement logic to check if food aligns with user preferences }); // Prioritize based on goals (e.g., calorie deficit) filteredFoods.sort((food1, food2) => { // Implement logic to compare foods based on goal criteria (e.g., calorie content) }); // Suggest meals with balanced macronutrients and variety const suggestedMeals = []; for (let i = 0; i < 3; i++) { // Suggest 3 meals for example const meal = []; // Implement logic to select and add foods to the meal while considering variety suggestedMeals.push(meal); } return suggestedMeals; } // Example usage: const userPreferences = { vegan: true }; const goals = { calorieTarget: 1800 }; const foods = yourStrapiFoodData; // Replace with actual food data const suggestedMeals = suggestMeals(userPreferences, goals, foods); console.log('Suggested meals:', suggestedMeals); ``` * This is a simplified example. The actual logic for filtering, prioritizing, and suggesting meals will involve more complex calculations and considerations. * Consider using libraries like Lodash for utility functions like filtering and sorting. **4. User Interface Integration:** * Present the suggested meals within your app's interface, allowing users to easily view and potentially customize them based on their preferences. * Provide options for users to provide feedback on the suggestions, further refining the engine over time. **5. Machine Learning (Optional):** * For a more advanced approach, explore integrating machine learning techniques like collaborative filtering to personalize meal suggestions based on user behavior and historical data. **Note:** * Implementing a robust meal suggestion engine requires careful consideration of user preferences, goal alignment, and dietary balance. * Start with a basic approach and gradually improve the recommendation logic based on user feedback and potential machine learning integration. ## Grocery List Generation Based on Planned Meals Here's how to implement grocery list generation based on planned meals in your nutrition app: **1. Data Integration:** * Ensure you have access to: * Planned meals data, including the list of ingredients for each meal. * Food data containing information like quantity units (e.g., grams, cups). **2. Logic for Grocery List Generation:** ```javascript function generateGroceryList(plannedMeals, foods) { const groceryList = {}; // Map to store ingredients and their quantities plannedMeals.forEach((meal) => { meal.ingredients.forEach((ingredient) => { const existingItem = groceryList[ingredient.foodId]; const foodData = foods.find((food) => food.id === ingredient.foodId); // Handle existing item in the list if (existingItem) { existingItem.quantity += ingredient.quantity; } else { // Add new item to the list with appropriate quantity and unit groceryList[ingredient.foodId] = { name: foodData.name, quantity: ingredient.quantity, unit: foodData.unit, // Assuming unit information exists in food data }; } }); }); return Object.values(groceryList); // Convert map to an array for easier display } ``` * This function iterates through planned meals and their ingredients. * It checks the grocery list for existing entries based on the food ID. * If an item already exists, it adds the new quantity to the existing one. * If a new item is encountered, it adds it to the list with details like name, quantity, and unit. **3. User Interface Integration:** * Display the generated grocery list in a dedicated section of your app. * Allow users to potentially: * Edit quantities for ingredients on the list. * Mark items as purchased or collected. * Export the list (e.g., print or share as a text file). ```javascript // components/GroceryList.js import React from 'react'; function GroceryList({ groceryList }) { return ( <div> <h2>Grocery List</h2> <ul> {groceryList.map((item) => ( <li key={item.name}> {item.quantity} {item.unit} - {item.name} </li> ))} </ul> </div> ); } export default GroceryList; ``` * This component displays the generated grocery list with item details (quantity, unit, name). **4. Additional Considerations:** * You might need to handle cases where a food item is used in multiple planned meals, ensuring accurate quantity accumulation in the grocery list. * Consider allowing users to set preferred grocery stores and potentially integrate with grocery delivery services (optional, advanced feature). ## Progress Tracking and Reports for Your Nutrition App **1. Data Collection and Storage:** * Track user data relevant to progress, such as: * Daily calorie intake and macronutrient (carbs, protein, fat) breakdown. * Weight measurements (if user chooses to track it). * Notes or reflections on meals and overall progress. * Utilize a database like Strapi to store this data securely. **2. User Interface for Tracking:** * Provide user-friendly interfaces for entering and reviewing progress data: * Allow users to log daily meals and their corresponding calorie/nutrient information. * Offer options for weight entries, potentially with charts visualizing weight trends over time. * Include a dedicated section for notes or reflections. ```javascript // components/DailyProgress.js import React, { useState } from 'react'; function DailyProgress({ date, onMealAdd, onWeightUpdate, onNoteSubmit }) { const [calories, setCalories] = useState(0); const [macros, setMacros] = useState({ carbs: 0, protein: 0, fat: 0 }); const [weight, setWeight] = useState(null); const [note, setNote] = useState(''); // Handle user input for calories, macros, weight, and notes return ( <div> <h2>Daily Progress - {date}</h2> <form onSubmit={(e) => onMealAdd(e, calories, macros)}> // Submit form to add meal data {/* Input fields for calories and macros */} </form> <form onSubmit={(e) => onWeightUpdate(e, weight)}> {/* Submit form to update weight */} <label htmlFor="weight">Weight:</label> <input type="number" id="weight" value={weight} onChange={(e) => setWeight(e.target.value)} /> </form> <textarea value={note} onChange={(e) => setNote(e.target.value)} /> {/* Text area for notes */} <button onClick={() => onNoteSubmit(note)}>Add Note</button> </div> ); } export default DailyProgress; ``` **3. Progress Reports:** * Generate reports summarizing user progress over a chosen period (week, month, etc.). * Utilize charts and graphs to visually represent trends in calorie intake, macronutrient distribution, and potentially weight changes (if tracked). * Allow users to compare progress against their initial goals or targets. ```javascript // components/ProgressReport.js import React, { useState, useEffect } from 'react'; import { Chart } from 'chart.js'; // Assuming using Chart.js library for charts function ProgressReport({ startDate, endDate, progressData }) { const [chartData, setChartData] = useState(null); useEffect(() => { // Prepare chart data based on progressData (e.g., daily calorie intake) const labels = progressData.map((day) => day.date); const calorieData = progressData.map((day) => day.calories); setChartData({ labels, datasets: [ { label: 'Daily Calorie Intake', data: calorieData, backgroundColor: 'rgba(255, 99, 132, 0.2)', borderColor: 'rgba(255, 99, 132, 1)', borderWidth: 1, }, ], }); }, [progressData]); return ( <div> <h2>Progress Report ({startDate} - {endDate})</h2> {chartData && <Chart type="line" data={chartData} />} {/* Display calorie intake chart */} {/* Display additional charts or metrics based on progressData */} </div> ); } export default ProgressReport; ``` **4. Additional Considerations:** * Allow users to customize the data displayed in reports (e.g., filter by date range, specific nutrients). * Integrate with wearable devices or fitness trackers to import weight and activity data (optional, advanced feature). * Provide motivational messages or insights based on user progress. ## Deployment Strategies for Your Nutrition App: Here's a breakdown of deployment options and considerations for your Next.js nutrition app: **1. Choosing a Deployment Platform:** * **Vercel:** A popular platform offering seamless deployment for Next.js applications. It integrates well with Git providers like GitHub and provides features like serverless functions and custom domains. * **Netlify:** Another popular option with a user-friendly interface and features like continuous deployment, environment variables, and global CDN (Content Delivery Network) for fast delivery. **2. Configuring Environment Variables:** Both Vercel and Netlify allow you to manage environment variables securely. These variables store sensitive information like API keys or database connection strings that shouldn't be exposed in your code. **Steps (using Vercel as an example):** 1. Go to your Vercel project settings. 2. Navigate to the "Environment" section. 3. Add key-value pairs for your environment variables (e.g., `NEXT_PUBLIC_STRAPI_URL` for your Strapi API endpoint, `USDA_API_KEY` for your USDA API key). 4. Access these variables in your Next.js app using `process.env.VARIABLE_NAME`. **3. Setting Up CI/CD Pipeline (Optional):** Continuous Integration/Continuous Delivery (CI/CD) automates the process of building, testing, and deploying your application.

### What is a Proxy Server and How Does it Work? A proxy server acts as an intermediary between a user’s computer and the internet. When you use a proxy server, your internet traffic is routed through the proxy, which makes requests on your behalf. This can enhance privacy, improve security, and allow you to bypass content restrictions.  #### Types of Proxy Servers 1. **Forward Proxy** - This is the most common type of proxy. It sits between a client and the wider internet, forwarding client requests to the internet. It can cache data, filter content, and manage bandwidth usage. 2. **Reverse Proxy** - Reverse proxies handle requests from the internet to internal servers. They are often used for load balancing, caching static content, and enhancing security by hiding the details of backend servers from the client. 3. **Web Proxy** - Specifically designed for web traffic, web proxies handle HTTP and HTTPS requests. They allow users to browse the internet anonymously by masking their IP addresses. 4. **Anonymous Proxy** - These proxies hide the user’s IP address from the destination server, offering a basic level of anonymity. They are commonly used to prevent tracking and protect user privacy. 5. **High Anonymity Proxy** - High anonymity proxies provide a higher level of privacy by frequently changing IP addresses and ensuring that the proxy server itself is not identifiable as a proxy. 6. **Transparent Proxy** - Transparent proxies do not modify the request or hide the user’s IP address. They are often used in organizational settings for content filtering and caching. 7. **Distorting Proxy** - These proxies provide a fake IP address to the destination server, offering an additional layer of anonymity by hiding the user’s true IP address. 8. **Rotating Proxy** - Rotating proxies change the IP address for each request, providing higher levels of anonymity and reducing the risk of IP bans. #### How Proxy Servers Work 1. **Client Request** - The client (your computer) sends a request to access a resource on the internet. This request is directed to the proxy server instead of directly to the destination server. 2. **Proxy Server** - The proxy server receives the client’s request, processes it, and then forwards it to the destination server. The destination server sees the request as coming from the proxy, not the client. 3. **Fetching the Resource** - The destination server processes the request and sends the response back to the proxy server. The proxy server then relays this response to the client. 4. **Caching** - Proxy servers often cache the responses from destination servers. If another client requests the same resource, the proxy can deliver it directly from its cache, improving load times and reducing bandwidth usage. #### Benefits of Using Proxy Servers 1. **Privacy and Anonymity** - By masking your IP address, proxies can help protect your identity online and prevent tracking by websites. 2. **Security** - Proxies can filter malicious content, block access to harmful sites, and protect against some types of cyber attacks. 3. **Access Control** - Organizations use proxies to restrict access to certain websites, ensuring that employees or users adhere to usage policies. 4. **Bandwidth Savings and Speed** - Caching frequently accessed content reduces bandwidth usage and improves loading times for users. 5. **Bypass Restrictions** - Proxies can help users bypass geographical restrictions and access content that might be blocked in their region. #### Risks and Considerations 1. **Lack of Encryption** - Most proxies do not encrypt your traffic, leaving it vulnerable to interception by hackers or third parties. 2. **Trust Issues** - Users must trust the proxy server provider as it can potentially monitor and log user activities. 3. **Performance** - Proxies can introduce latency and slow down internet connections, especially if they are overloaded or poorly configured. 4. **Legal and Ethical Concerns** - Using proxies to bypass restrictions or access blocked content can sometimes violate terms of service or local laws. Proxy servers are versatile tools that can enhance your online experience by providing privacy, security, and access control. However, it’s essential to choose the right type of proxy and understand its limitations and risks.  For more detailed information on proxy servers, you can visit resources such as [Kinsta](https://kinsta.com), [Wikipedia](https://en.wikipedia.org), [TechRadar](https://www.techradar.com), and [AVG](https://www.avg.com).

## What is HTTPS and How Does it Work? ### Introduction HTTPS, which stands for Hypertext Transfer Protocol Secure, is an advanced version of the standard HTTP protocol. It adds a layer of security by encrypting data transmitted between a user's browser and a web server. This encryption ensures that sensitive information remains confidential and protected from eavesdropping and tampering.  ### How HTTPS Works HTTPS utilizes two primary components: the HTTPS protocol and the Transport Layer Security (TLS) protocol. #### Encryption and Authentication 1. **TLS Encryption**: HTTPS encrypts data using TLS, formerly known as SSL (Secure Sockets Layer). TLS employs asymmetric encryption, which uses a pair of keys: a public key to encrypt data and a private key to decrypt it. This ensures that even if data is intercepted, it cannot be read without the private key. 2. **Digital Certificates**: Websites using HTTPS have a digital certificate issued by a Certificate Authority (CA). This certificate verifies the website's identity, ensuring users that they are communicating with the legitimate site and not an imposter. #### The HTTPS Process 1. **SSL/TLS Handshake**: When a user connects to an HTTPS-secured website, their browser and the server perform a handshake. During this process, the server presents its digital certificate to the browser. 2. **Certificate Verification**: The browser checks the certificate against a list of trusted CAs. If the certificate is valid, the browser and server establish a secure, encrypted connection. 3. **Data Transmission**: Once the secure connection is established, data can be transmitted safely between the browser and the server. This encrypted data cannot be intercepted or altered by third parties. ### Benefits of HTTPS 1. **Enhanced Security**: HTTPS protects against various attacks, including man-in-the-middle attacks, where an attacker intercepts and possibly alters the communication between two parties. 2. **Data Integrity**: HTTPS ensures that data transferred between the browser and the server is not tampered with during transmission. 3. **Privacy**: It keeps user data confidential, protecting sensitive information like login credentials, credit card details, and personal information. 4. **Trust and SEO**: Websites using HTTPS are often marked with a padlock icon in the browser's address bar, signaling to users that the site is secure. This fosters trust and can positively impact user behavior. Additionally, search engines like Google use HTTPS as a ranking signal, potentially improving a site's visibility in search results. ### Why HTTPS is Important Without HTTPS, data transmitted over the internet is sent in plain text, making it vulnerable to interception and manipulation. HTTPS encrypts this data, providing a secure communication channel that protects against eavesdropping and data breaches. It is crucial for protecting user privacy, maintaining data integrity, and securing online transactions. ### Conclusion HTTPS has become the standard for secure internet communication, providing essential protection for users and their data. By ensuring encrypted and authenticated data transmission, HTTPS plays a vital role in securing the modern web. ### Images and Visuals Including images that illustrate the SSL/TLS handshake process, the appearance of the HTTPS padlock in browsers, and examples of encrypted versus plain text data can help visualize the concepts discussed in this article.  ### References 1.

### Understanding SSL: The Backbone of Internet Security **Introduction** In the digital age, secure communication is paramount. Secure Sockets Layer (SSL), and its successor Transport Layer Security (TLS), are cryptographic protocols designed to provide security over a computer network. Although SSL has been largely replaced by TLS, the term SSL is still widely used to refer to both protocols.  **What is SSL?** SSL stands for Secure Sockets Layer, a protocol developed to ensure secure, encrypted communications between a client (like a web browser) and a server (such as a web server). SSL was designed to prevent eavesdropping, tampering, and message forgery over the internet. ### How SSL/TLS Works The primary function of SSL/TLS is to encrypt data being transmitted between two systems, ensuring that any data transferred remains private and integral. Here’s a simplified breakdown of the process:  1. **Handshake Process**: - **Client Hello**: The client sends a request to the server, including supported encryption methods and a randomly generated data string. - **Server Hello**: The server responds with its own random data string, chosen encryption method, and its SSL certificate. - **Certificate Verification**: The client verifies the server's SSL certificate with a trusted Certificate Authority (CA). - **Session Keys**: The client generates a session key, encrypts it with the server's public key, and sends it to the server. The server decrypts the session key with its private key. - **Encrypted Session**: Both parties use the session key for symmetric encryption of data, ensuring secure communication for the duration of the session【7†source】【9†source】. ### Types of SSL/TLS Certificates SSL/TLS certificates authenticate the identity of the website and encrypt the data. There are several types of certificates based on the level of validation: 1. **Domain Validated (DV) Certificates**: Basic level, verifying the domain owner. 2. **Organization Validated (OV) Certificates**: Involves checking the organization behind the domain. 3. **Extended Validation (EV) Certificates**: Provides the highest level of security and assurance by validating the organization's identity extensively【8†source】. ### Benefits of SSL/TLS - **Encryption**: SSL/TLS ensures that data transmitted between a client and a server is encrypted, protecting it from interception and tampering. - **Authentication**: Validates that the website you are communicating with is indeed the intended site. - **Data Integrity**: Ensures that data cannot be altered during transfer without being detected. - **SEO Benefits**: Search engines like Google give preference to HTTPS websites, potentially boosting rankings【9†source】. ### SSL/TLS in Use: HTTPS The visible indicator of SSL/TLS in action is HTTPS (Hyper Text Transfer Protocol Secure). When you see "https://" in your browser’s address bar along with a padlock icon, it means the site is secured by SSL/TLS, ensuring encrypted and authenticated communication between your browser and the server【7†source】【8†source】. ### Conclusion SSL/TLS are critical components of internet security, safeguarding data from interception and tampering. By encrypting communications and verifying identities, SSL/TLS helps maintain privacy and trust online. Whether you run a blog, an e-commerce site, or any other online service, implementing SSL/TLS is essential for protecting your users and ensuring secure communication.

In this article, I will analyze my decision to combine Bootstrap, the most popular CSS framework for developing responsive and mobile-first websites, with a CSS preprocessor, specifically SASS, for my personal project. Bootstrap simplifies the process of writing CSS by allowing you to add classes to elements, while SASS enhances CSS with additional features, making your code more efficient and maintainable. Combining these tools can streamline your workflow and improve the overall quality of your web projects. ## Installing Bootstrap There are two ways to install Bootstrap in your project. **Include from CDN** Using a Content Delivery Network (CDN) is quick and easy. To include Bootstrap via CDN, add the following lines of code to your HTML file: ``` <link rel=”stylesheet” href=”https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css”rel=”nofollow” integrity=”sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm” crossorigin=”anonymous”> ``` And for JS place this line of code at the bottom of the body element( for what's included in this script, please read more [here](https://getbootstrap.com/docs/5.0/getting-started/introduction/)): ``` <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js" integrity="sha384-MrcW6ZMFYlzcLA8Nl+NtUVF0sA7MsXsP1UyJoMp4YLEuNSfAP+JcXn/tWtIaxVXM" crossorigin="anonymous"></script> ``` **Download files locally** Another way of importing Bootstrap to HTML is to directly download the files locally to your HTML project folder. The files can be downloaded from the following links: Bootstrap 4: [https://getbootstrap.com/docs/4.3/getting-started/download/](https://getbootstrap.com/docs/4.3/getting-started/download/) Bootstrap 5: [https://v5.getbootstrap.com/docs/5.0/getting-started/download/](https://v5.getbootstrap.com/docs/5.0/getting-started/download/) ## SASS SASS (Syntactically Awesome Style Sheets) is a CSS preprocessor that allows you to write more flexible and maintainable CSS. It adds features such as variables, nested rules, and mixins, which streamline your CSS and make it more powerful. ## Installing sass One easy and simple way to install SASS in your project is by using a package manager. For this project, I used npm. To install SASS, run the following command: ``` npm install sass ``` ## Why combine Sass and Bootstrap Combining SASS and Bootstrap allows you to leverage the best of both worlds. Bootstrap helps you build your layout quickly with pre-designed components, while SASS enables you to write reusable and modular CSS for custom parts of your design. Although it might add some unused CSS to your project, the benefits of reusability and maintainability outweigh this downside. ## Benefits combining Sass with Bootstrap - **Quick Layout Building**: Bootstrap’s predefined classes help you create responsive layouts rapidly. - **Custom Styling**: SASS allows you to write custom styles that can be reused across your project, making your CSS more efficient. - **Maintainability**: Using SASS features like variables and mixins can make your CSS easier to manage and update. ## Conclusion In conclusion, combining Bootstrap with SASS can significantly enhance your web development workflow. Bootstrap’s ready-to-use components, paired with SASS’s powerful features, allow you to create efficient, maintainable, and scalable web designs. While it may introduce some unused CSS, the benefits of customizability and reusability make it a worthwhile approach. I encourage you to try this combination in your projects and experience the improved productivity and organization it brings.

https://dev.to/devdera/linux-user-creation-bash-script-1hfm

[As part of the HNG Internship program, we were tasked with creating a bash script named create_users.sh to automate the creation of new users and groups on a Linux system. Checkout (https://hng.tech/internship) and (https://hng.tech/premium) for more information] **Overview** This script, create_users.sh, automates the creation of users and their associated groups, sets up their home directories, generates random passwords, and logs all actions. The script reads from a specified text file containing usernames and group names. **Prerequisites** The script must be run with root privileges. Ensure the input file with usernames and groups is formatted correctly and exists. **Script steps** I created a file called Create_Users.sh Using vim editor, I created a log file , password.txt file . Ensure my script is run as root and set up specific instructions and permissions. Below is the content of the script. ##!/bin/bash # Create log file and secure password file with proper permissions LOG_FILE="/var/secure/user_management.log" PASSWORD_FILE="/var/secure/user_passwords.txt" # Ensure the script is run as root if [[ "$(id -u)" -ne 0 ]]; then echo "This script must be run as root." exit 1 fi # Ensure the log file exists touch "$LOG_FILE" # Setup password file if [[ ! -d "/var/secure" ]]; then mkdir /var/secure fi if [[ ! -f "$PASSWORD_FILE" ]]; then touch "$PASSWORD_FILE" chmod 600 "$PASSWORD_FILE" fi # Check if the input file is provided if [[ -z "$1" ]]; then echo "Usage: bash create_users.sh <name-of-text-file>" echo "$(date '+%Y-%m-%d %H:%M:%S') - ERROR: No input file provided." >> "$LOG_FILE" exit 1 fi # Read the input file line by line while IFS=';' read -r username groups; do # Skip empty lines [[ -z "$username" ]] && continue # Remove whitespace username=$(echo "$username" | xargs) groups=$(echo "$groups" | xargs) # Create user if not exists if ! id "$username" &>/dev/null; then # Create the user with a home directory useradd -m -s /bin/bash "$username" if [[ $? -ne 0 ]]; then echo "$(date '+%Y-%m-%d %H:%M:%S') - ERROR: Failed to create user $username." >> "$LOG_FILE" continue fi echo "$(date '+%Y-%m-%d %H:%M:%S') - INFO: User $username created." >> "$LOG_FILE" # Generate a random password for the user password=$(openssl rand -base64 12) echo "$username:$password" | chpasswd # Save the password to the secure password file echo "$username,$password" >> "$PASSWORD_FILE" echo "$(date '+%Y-%m-%d %H:%M:%S') - INFO: Password for user $username generated and stored." >> "$LOG_FILE" else echo "$(date '+%Y-%m-%d %H:%M:%S') - INFO: User $username already exists." >> "$LOG_FILE" fi # Create groups and add user to them IFS=',' read -ra group_list <<< "$groups" for group in "${group_list[@]}"; do group=$(echo "$group" | xargs) # Create group if not exists if ! getent group "$group" >/dev/null; then groupadd "$group" echo "$(date '+%Y-%m-%d %H:%M:%S') - INFO: Group $group created." >> "$LOG_FILE" fi # Add user to the group usermod -a -G "$group" "$username" echo "$(date '+%Y-%m-%d %H:%M:%S') - INFO: User $username added to group $group." >> "$LOG_FILE" done # Set ownership and permissions for the home directory chown -R "$username:$username" "/home/$username" chmod 700 "/home/$username" echo "$(date '+%Y-%m-%d %H:%M:%S') - INFO: Home directory for user $username set up with appropriate permissions." >> "$LOG_FILE" done < "$1" echo "$(date '+%Y-%m-%d %H:%M:%S') - INFO: User creation script completed." >> "$LOG_FILE" exit 0# Next, I created an employees.txt file for the usernames and groups. Granted permission to the Create_Users.sh file using chmod +x /home/kali/Desktop/HNG/Create_Users.sh (this is the file path) and sudo /home/kali/Desktop/HNG/Create_Users.sh /home/kali/Desktop/HNG/employees.txt. **Verify Execution** Input the following to verify execution id John for user creation verification Groups John to verify the groups John is in. Cat /var/log/user_management.log to print log details.

nextjs, middleware, authjs, security

In modern web development, implementing a robust authentication system is crucial for securing user data and providing a seamless user experience. In this blog post, we'll explore how to implement authentication in a Next.js application using JSON Web Tokens (JWT) and MongoDB. We'll cover the key aspects of this implementation, including middleware, token management, and user registration and login. **Setting Up Middleware for Route Protection** The middleware function plays a crucial role in protecting routes and ensuring that users are authenticated before accessing certain pages. Here's the implementation of the middleware function: ``` import { getToken, verifyToken } from "@/lib/auth"; import { NextResponse } from "next/server"; import type { NextRequest } from "next/server"; export async function middleware(request: NextRequest) { const token = getToken(request); const { pathname } = request.nextUrl; if (token) { const payload = await verifyToken(token); if (payload) { if (pathname === "/" || pathname === "/register") { return NextResponse.redirect(new URL("/home", request.url)); } return NextResponse.next(); } } if (pathname !== "/" && pathname !== "/register") { return NextResponse.redirect(new URL("/", request.url)); } return NextResponse.next(); } export const config = { matcher: ["/((?!api|_next/static|_next/image|favicon.ico).*)"], }; ``` This middleware function checks if a token exists and verifies it. If the token is valid, it allows the user to proceed to the requested route. If the token is invalid or missing, it redirects the user to the login page. **Managing Tokens with JSON Web Tokens (JWT)** To handle token generation and verification, we use the jose library. Below are the utility functions for managing JWTs: ``` import { jwtVerify, SignJWT } from 'jose'; import { NextRequest } from "next/server"; export function getToken(req: NextRequest) { return req.cookies.get("token")?.value; } export async function verifyToken(token: string) { if (!token) return null; try { const secret = new TextEncoder().encode(process.env.JWT_SECRET); const { payload } = await jwtVerify(token, secret); return payload as { userId: string }; } catch (error) { console.error('Token verification failed:', error); return null; } } export async function createToken(payload: { userId: string }) { const secret = new TextEncoder().encode(process.env.JWT_SECRET!); const token = await new SignJWT(payload) .setProtectedHeader({ alg: 'HS256' }) .setExpirationTime('1d') .sign(secret); return token; } ``` These functions handle retrieving the token from cookies, verifying the token, and creating a new token. The verifyToken function ensures that the token is valid and extracts the payload, while createToken generates a new token with a specified payload. **User Registration and Login** For user registration and login, we need to handle form data, hash passwords, and create tokens. Here's how we achieve this: ``` "use server"; import { cookies } from "next/headers"; import bcrypt from "bcryptjs"; import { connectToDB } from "@/lib/db"; import User from "@/models/User"; import { loginSchema, registerSchema } from "@/zod/schema"; import { createToken } from "@/lib/auth"; export async function registerUser(formData: FormData) { await connectToDB(); const parsedData = registerSchema.parse( Object.fromEntries(formData.entries()) ); const existingUser = await User.findOne({ email: parsedData.email }); if (existingUser) { throw new Error("Email already exists"); } const hashedPassword = await bcrypt.hash(parsedData.password, 10); const newUser = await User.create({ ...parsedData, password: hashedPassword, createdAt: new Date(), }); const token = await createToken({ userId: newUser._id.toString() }); const cookieStore = cookies(); cookieStore.set("token", token, { httpOnly: true, secure: process.env.NODE_ENV === "production", }); } export async function loginUser(formData: FormData) { const { email, password } = loginSchema.parse( Object.fromEntries(formData.entries()) ); await connectToDB(); const user = await User.findOne({ email }); if (!user) { throw new Error("Invalid credentials"); } const isPasswordValid = await bcrypt.compare(password, user.password); if (!isPasswordValid) { throw new Error("Invalid credentials"); } const token = await createToken({ userId: user._id.toString() }); const cookieStore = cookies(); cookieStore.set("token", token, { httpOnly: true, secure: process.env.NODE_ENV === "production", }); } export async function logoutUser() { cookies().set("token", "", { expires: new Date(0) }); } ``` registerUser: This function handles user registration. It connects to the database, parses the form data, checks if the email already exists, hashes the password, creates a new user, generates a token, and sets the token as an HTTP-only cookie. loginUser: This function handles user login. It parses the form data, connects to the database, verifies the user's credentials, generates a token, and sets the token as an HTTP-only cookie. logoutUser: This function handles user logout by clearing the token cookie. **Conclusion** Implementing authentication in a Next.js application using JWT and MongoDB provides a secure and efficient way to manage user sessions. By leveraging middleware, JWT, and MongoDB, we can protect routes, verify tokens, and handle user registration and login seamlessly.

nextjs, react, authjs, otp

In today's digital age, ensuring the security of user authentication is paramount. One effective method is using One-Time Passwords (OTPs) for login. In this post, we'll walk through how to implement an OTP-based login system using Next.js, with both email and phone number options. **Why Use OTP?** OTPs add an extra layer of security by requiring a temporary code sent to the user's email or phone number. This method reduces the risk of unauthorized access, as the code is valid for a short period. **Setting Up the Frontend** We start by creating a login component that captures the user's email or phone number and handles OTP sending and verification. ``` //login component "use client"; import { useState, useEffect } from "react"; import { Input } from "@/components/ui/input"; import { Lock, Mail, Phone } from "lucide-react"; import { Button } from "@/components/ui/button"; import { InputOTP, InputOTPGroup, InputOTPSlot, } from "@/components/ui/input-otp"; import { SendOTP } from "@/utils/SendOTP"; import { useRouter } from "next/navigation"; import { signIn } from "next-auth/react"; const Login = () => { const [contact, setContact] = useState(""); const [otp, setOtp] = useState(false); const [otpCode, setOtpCode] = useState(""); const [receivedOtpCode, setReceivedOtpCode] = useState(""); const [timeLeft, setTimeLeft] = useState(60); const [timerRunning, setTimerRunning] = useState(false); const [resendClicked, setResendClicked] = useState(false); const [hasPassword, setHasPassword] = useState(false); const [password, setPassword] = useState(""); const [isIncorrectOTP, setIsIncorrectOTP] = useState(false); const router = useRouter(); const handleSendOtp = async () => { setOtp(true); startTimer(); setResendClicked(true); const data = await SendOTP(contact); if (data?.hasPassword) { setHasPassword(data?.hasPassword); } if (data?.otp) { setReceivedOtpCode(data?.otp); } }; const handleLogin = async () => { if (otpCode === receivedOtpCode) { await signIn("credentials", { redirect: false, email: isNaN(contact) ? contact : contact + "@gmail.com", }); router.push("/"); } else { setIsIncorrectOTP(true); } }; const startTimer = () => { setTimeLeft(60); setTimerRunning(true); }; const resendOTP = () => { setTimerRunning(false); startTimer(); setResendClicked(true); handleSendOtp(); }; useEffect(() => { let timer; if (timerRunning) { timer = setTimeout(() => { if (timeLeft > 0) { setTimeLeft((prevTime) => prevTime - 1); } else { setTimerRunning(false); } }, 1000); } return () => clearTimeout(timer); }, [timeLeft, timerRunning]); useEffect(() => { if (contact === "" || contact === null) { setOtp(false); setOtpCode(""); setTimeLeft(60); setTimerRunning(false); setResendClicked(false); } }, [contact]); return ( <div> <div className="relative w-full max-w-sm"> {contact === "" || isNaN(contact) ? ( <Mail className="absolute left-3 top-1/2 transform -translate-y-1/2 text-gray-400" size={20} /> ) : ( <Phone className="absolute left-3 top-1/2 transform -translate-y-1/2 text-gray-400" size={20} /> )} <Input type="text" name="contact" value={contact} placeholder="Email or phone" onChange={(e) => setContact(e.target.value)} disabled={contact && otp} className="pl-10" /> </div> {hasPassword ? ( <div className="relative w-full max-w-sm mt-4"> <Lock className="absolute left-3 top-1/2 transform -translate-y-1/2 text-gray-400" size={20} /> <Input type="password" name="password" value={password} placeholder="Password" onChange={(e) => setPassword(e.target.value)} className="pl-10" /> </div> ) : ( <div> {contact && otp && ( <div className="text-center text-green-500 text-base mt-1"> OTP sent successfully. Please enter OTP below. </div> )} {contact && otp && ( <div className="space-y-2 w-full flex flex-col items-center justify-center my-2"> <InputOTP maxLength={4} value={otpCode} onChange={(value) => setOtpCode(value)} isError={isIncorrectOTP} > <InputOTPGroup> <InputOTPSlot index={0} /> <InputOTPSlot index={1} /> <InputOTPSlot index={2} /> <InputOTPSlot index={3} /> </InputOTPGroup> </InputOTP> <div> {resendClicked && timeLeft > 0 ? ( <p className="text-sm"> Resend OTP available in{" "} <span className="text-blue-500"> {timeLeft > 0 ? `${timeLeft}` : ""} </span> </p> ) : ( <Button variant="link" onClick={resendOTP} className="text-blue-500" > Resend OTP </Button> )} </div> </div> )} </div> )} {receivedOtpCode ? ( <Button onClick={handleLogin} className="w-full mt-4 bg-green-500 hover:bg-green-400" > Login </Button> ) : ( <Button onClick={handleSendOtp} className="w-full mt-4 bg-green-500 hover:bg-green-400" > Next </Button> )} {isIncorrectOTP && ( <p className="text-red-500 text-sm text-center mt-2"> Incorrect OTP. Please try again. </p> )} </div> ); }; export default Login; ``` This component manages the user interaction for entering their contact information, sending the OTP, and handling the login process. It includes state management for various aspects such as OTP verification, countdown timer, and error handling. **Backend API for OTP Generation and Sending** Next, we'll set up the backend to handle OTP generation and sending. The OTP can be sent via email or SMS based on the user's contact information. ``` //OTP Generation and Sending import { sendVerificationSMS } from "@/lib/sendSMS"; import User from "@/models/user"; import { NextResponse } from "next/server"; import { connectToDB } from "@/lib/db"; import nodemailer from "nodemailer"; const generateOTP = () => { const digits = "0123456789"; let OTP = ""; for (let i = 0; i < 4; i++) { OTP += digits[Math.floor(Math.random() * 10)]; } return OTP; }; const sendVerificationEmail = async (contact, otp) => { try { let transporter = nodemailer.createTransport({ service: "gmail", auth: { user: "[email protected]", pass: "your-email-password", }, }); let info = await transporter.sendMail({ from: `"Your Company" <[email protected]>`, to: contact, subject: "Verification Code", text: `Your verification code is: ${otp}`, }); return info.messageId; } catch (error) { console.error("Error sending email:", error); throw new Error("Error sending verification email"); } }; export async function POST(req, res) { try { await connectToDB(); const otp = generateOTP(); const { contact } = await req.json(); const existingUser = await User.findOne({ email: isNaN(contact) ? contact : contact + "@gmail.com", }); if (isNaN(contact)) { await sendVerificationEmail(contact, otp); return NextResponse.json({ message: "Verification code has been sent to your email", otp, }); } else { await sendVerificationSMS(contact, otp); return NextResponse.json({ message: "Verification code has been sent", otp, }); } } catch (error) { console.error(error); return NextResponse.error( "An error occurred while processing the request." ); } } ``` This backend code handles OTP generation and sends it either via email or SMS depending on the user's input. The generateOTP function creates a random 4-digit OTP, and the sendVerificationEmail and sendVerificationSMS functions send the OTP to the user. **Conclusion** Implementing an OTP-based login system enhances the security of your application by adding an additional verification step. This system ensures that only users with access to the provided email or phone number can log in, protecting against unauthorized access. Feel free to modify and expand upon this basic implementation to suit your specific requirements. Happy coding!

https://dev.to/tim_shantel/automating-user-and-group-management-with-bash-ooc

### Introduction As a SysOps engineer, managing users and groups on a server is one of your routine tasks. This process can be quite time-consuming and susceptible to errors, particularly when handling numerous users. Automating these tasks is crucial for achieving efficiency and reliability. This article will guide you through a Bash script that automates the creation of users and groups, sets up home directories with correct permissions, generates random passwords, and logs all actions. ### Bash Bash which stands for "Bourne Again Shell" is a command language interpreter and scripting language commonly used in Unix-like operating systems, such as linux and macOS. It's the default shell for most linux distributions and is widely used for automation tasks, managing system operations, and write scrips. #### What is Bash script? A Bash script is a file typically ending with the extension .sh that contain a logical series of related commands to be executed This project was inspired by HNG internship 11 https://hng.tech/hire, DevOps track of stage one. visit https://hng.tech/internship to learn more about the program ### Prerequisite Before we start, ensure you have: - Access to a linux server with root privileges - Basic knowledge of Bash scripting ### Script Overview The script we'll create will: 1. Create users and groups 2. set up home directories with the correct permissions 3. Generate random passwords for users 4. Log all actions to a specified log file ### User Management Automation project Let's dive into an extensive project that will show us a step by step guide on how to create user and group management with Bash script. Here is a step by step guide on how to create user and groups management: ## Creating the script file First and foremost, Create a new Bash script file ``` touch create_user.sh ``` Open the file in your preferred text editor: ``` vim create_user.sh ``` Create an employee file where users and group would be located ``` touch employeefile.txt ``` edit your user_data.txt file with a text editor and enter the following user and group below: ``` vim employeefile.txt ``` ### Example Input File light; sudo,dev, www-data idimma;sudo mayowa;dev,www-data **Insert the following script below into your 'create_users.sh' file** ### The Script ``` #!/bin/bash # Define log and password files LOG_FILE="/var/log/user_management.log" PASSWORD_FILE="/var/secure/user_passwords.txt" # Create log and password files if they don't exist touch $LOG_FILE mkdir -p /var/secure touch $PASSWORD_FILE # Function to log messages log_message() { echo "$(date +'%Y-%m-%d %H:%M:%S') - $1" | tee -a $LOG_FILE } # Function to generate random password generate_password() { tr -dc A-Za-z0-9 </dev/urandom | head -c 12 ; echo '' } # Check if the input file is provided if [ $# -ne 1 ]; then echo "Usage: $0 <input_file>" exit 1 fi # Read the input file INPUT_FILE=$1 # Check if the input file exists if [ ! -f $INPUT_FILE ]; then echo "Input file not found!" exit 1 fi while IFS=';' read -r username groups; do # Remove leading and trailing whitespaces username=$(echo $username | xargs) groups=$(echo $groups | xargs) if id "$username" &>/dev/null; then log_message "User $username already exists. Skipping..." continue fi # Create a personal group for the user groupadd $username if [ $? -ne 0 ]; then log_message "Failed to create group $username." continue fi log_message "Group $username created successfully." # Create user and add to personal group useradd -m -g $username -s /bin/bash $username if [ $? -ne 0 ]; then log_message "Failed to create user $username." continue fi log_message "User $username created successfully." # Create additional groups if they don't exist and add user to groups IFS=',' read -ra group_array <<< "$groups" for group in "${group_array[@]}"; do group=$(echo $group | xargs) if [ -z "$group" ]; then continue fi if ! getent group $group >/dev/null; then groupadd $group if [ $? -ne 0 ]; then log_message "Failed to create group $group." continue fi log_message "Group $group created successfully." fi usermod -aG $group $username log_message "User $username added to group $group." done # Set up home directory permissions chmod 700 /home/$username chown $username:$username /home/$username log_message "Permissions set for home directory of $username." # Generate random password and store it password=$(generate_password) echo "$username:$password" | chpasswd echo "$username:$password" >> $PASSWORD_FILE log_message "Password set for user $username." done < "$INPUT_FILE" log_message "User and group creation process completed." exit 0 ``` **Make the script executable** ``` chmod +x create_user.sh ``` **Execute the script** ``` sudo bash ./create_users.sh employeefile.txt ``` ## Defining the Script Start by defining the script header and setting some initial variables: **Define Log and Password Files** ``` #!/bin/bash # Define log and password files LOG_FILE="/var/log/user_management.log" PASSWORD_FILE="/var/secure/user_passwords.txt" ``` These lines set the paths for the log file and the file where passwords will be stored. **Create Log and Password Files if They Don't Exist** ``` # Create log and password files if they don't exist touch $LOG_FILE mkdir -p /var/secure touch $PASSWORD_FILE ``` - touch $LOG_FILE creates the log file if it doesn't already exist. - mkdir -p /var/secure creates the directory /var/secure if it doesn't exist. - touch $PASSWORD_FILE creates the password file if it doesn't exist. **Function to Log Messages** ``` # Function to log messages log_message() { echo "$(date +'%Y-%m-%d %H:%M:%S') - $1" | tee -a $LOG_FILE } ``` This function logs messages with a timestamp. tee -a $LOG_FILE appends the log message to the log file while also displaying it on the console. **Function to Generate Random Password** ``` # Function to generate random password generate_password() { tr -dc A-Za-z0-9 </dev/urandom | head -c 12 ; echo '' } ``` This function generates a random 12-character password using characters from A-Z, a-z, and 0-9. **Check if the Input File is Provided** ``` # Check if the input file is provided if [ $# -ne 1 ]; then echo "Usage: $0 <input_file>" exit 1 fi ``` This part ensures that the script is called with exactly one argument (the input file). If not, it displays a usage message and exits. **Read the Input File** ``` # Read the input file INPUT_FILE=$1 ``` This assigns the first argument (input file) to the variable INPUT_FILE. **Check if the Input File Exists** ``` # Check if the input file exists if [ ! -f $INPUT_FILE ]; then echo "Input file not found!" exit 1 fi ``` This checks if the input file exists. If not, it prints an error message and exits. **Process Each Line of the Input File** ``` while IFS=';' read -r username groups; do # Remove leading and trailing whitespaces username=$(echo $username | xargs) groups=$(echo $groups | xargs) ``` - IFS=';' read -r username groups reads each line of the input file, splitting the line into username and groups using ; as a delimiter. - xargs is used to trim leading and trailing whitespaces from username and groups. **Check if the User Already Exists** ``` if id "$username" &>/dev/null; then log_message "User $username already exists. Skipping..." continue fi ``` This checks if the user already exists. If the user exists, it logs a message and skips to the next iteration. **Create a Personal Group for the User** ``` # Create a personal group for the user groupadd $username if [ $? -ne 0 ]; then log_message "Failed to create group $username." continue fi log_message "Group $username created successfully." ``` - groupadd $username creates a new group with the same name as the user. - $? checks the exit status of the groupadd command. If it's not zero (indicating an error), it logs a failure message and skips to the next iteration. - If the group is created successfully, it logs a success message. Create the User and Add to Personal Group ``` # Create user and add to personal group useradd -m -g $username -s /bin/bash $username if [ $? -ne 0 ]; then log_message "Failed to create user $username." continue fi log_message "User $username created successfully." ``` - useradd -m -g $username -s /bin/bash $username creates the user with a home directory and assigns the personal group. - The exit status is checked, and appropriate messages are logged. **Create Additional Groups and Add User to Them** ``` # Create additional groups if they don't exist and add user to groups IFS=',' read -ra group_array <<< "$groups" for group in "${group_array[@]}"; do group=$(echo $group | xargs) if [ -z "$group" ]; then continue fi if ! getent group $group >/dev/null; then groupadd $group if [ $? -ne 0 ]; then log_message "Failed to create group $group." continue fi log_message "Group $group created successfully." fi usermod -aG $group $username log_message "User $username added to group $group." done ``` - IFS=',' read -ra group_array <<< "$groups" splits the groups string into an array. - The script iterates over the array, trims whitespaces, checks if the group is empty, and continues to the next iteration if it is. - It checks if each group exists using getent group $group. If the group does not exist, it creates it. - The user is added to the group using usermod -aG $group $username. Appropriate messages are logged throughout **Set Up Home Directory Permissions** ``` # Set up home directory permissions chmod 700 /home/$username chown $username:$username /home/$username log_message "Permissions set for home directory of $username." ``` - chmod 700 /home/$username sets the permissions of the user's home directory. - chown $username:$username /home/$username changes the ownership of the home directory to the user. - A log message is recorded. **Generate Random Password and Store It** ``` # Generate random password and store it password=$(generate_password) echo "$username:$password" | chpasswd echo "$username:$password" >> $PASSWORD_FILE log_message "Password set for user $username." ``` - password=$(generate_password) generates a random password. - echo "$username:$password" | chpasswd sets the user's password. - The password is stored in the password file. - A log message is recorded. **Complete the Process** ``` done < "$INPUT_FILE" log_message "User and group creation process completed." exit 0 ``` - The done statement ends the while loop. - A log message indicates that the process is complete. - exit 0 exits the script successfully. This detailed breakdown should help you understand each part of the script and its function as you run it in your terminal.

Lit and Figma

In this article I will go over how to set up a Lit web component and use it to create a figma plugin....

https://rodydavis.com/posts/figma-and-lit/

--- title: Lit and Figma published: true date: 2021-05-10 00:00:00 UTC tags: canonical_url: https://rodydavis.com/posts/figma-and-lit/ --- In this article I will go over how to set up a [Lit](https://lit.dev/) web component and use it to create a figma plugin. **TLDR** You can find the final source [here](https://github.com/rodydavis/figma_lit_example). ## Prerequisites [#](#prerequisites) - Vscode - Figma Desktop - Node - Typescript ## Getting Started [#](#getting-started) We can start off by creating a empty directory and naming it with `snake_case` whatever we want. ``` mkdir figma_lit_examplecd figma_lit_example ``` ### Web Setup [#](#web-setup) Now we are in the `figma_lit_example` directory and can setup Figma and Lit. Let's start with node. ``` npm init -y ``` This will setup the basics for a node project and install the packages we need. Now lets add some config files. Now open the `package.json` and replace it with the following: ``` { "name": "figma_lit_example", "version": "1.0.0", "description": "Lit Figma Plugin", "dependencies": { "lit": "^2.0.0-rc.1" }, "devDependencies": { "@figma/plugin-typings": "^1.23.0", "html-webpack-inline-source-plugin": "^1.0.0-beta.2", "html-webpack-plugin": "^4.3.0", "css-loader": "^5.2.4", "ts-loader": "^8.0.0", "typescript": "^4.2.4", "url-loader": "^4.1.1", "webpack": "^4.44.1", "webpack-cli": "^4.6.0" }, "scripts": { "dev": "npx webpack --mode=development --watch", "copy": "mkdir -p lit-plugin && cp ./manifest.json ./lit-plugin/manifest.json && cp ./dist/ui.html ./lit-plugin/ui.html && cp ./dist/code.js ./lit-plugin/code.js", "build": "npx webpack --mode=production && npm run copy", "zip": "npm run build && zip -r lit-plugin.zip lit-plugin" }, "browserslist": ["last 1 Chrome versions"], "keywords": [], "author": "", "license": "ISC"} ``` This will add everything we need and add the scripts we need for development and production. Then run the following: ``` npm i ``` This will install everything we need to get started. Now we need to setup some config files. ``` touch tsconfig.jsontouch webpack.config.ts ``` This will create 2 files. Now open up `tsconfig.json` and paste the following: ``` { "compilerOptions": { "target": "es2017", "module": "esNext", "moduleResolution": "node", "lib": ["es2017", "dom", "dom.iterable"], "typeRoots": ["./node_modules/@types", "./node_modules/@figma"], "declaration": true, "sourceMap": true, "inlineSources": true, "noUnusedLocals": true, "noImplicitReturns": true, "noFallthroughCasesInSwitch": true, "experimentalDecorators": true, "skipLibCheck": true, "strict": true, "noImplicitAny": false, "outDir": "./lib", "baseUrl": "./packages", "importHelpers": true, "plugins": [{ "name": "ts-lit-plugin", "rules": { "no-unknown-tag-name": "error", "no-unclosed-tag": "error", "no-unknown-property": "error", "no-unintended-mixed-binding": "error", "no-invalid-boolean-binding": "error", "no-expressionless-property-binding": "error", "no-noncallable-event-binding": "error", "no-boolean-in-attribute-binding": "error", "no-complex-attribute-binding": "error", "no-nullable-attribute-binding": "error", "no-incompatible-type-binding": "error", "no-invalid-directive-binding": "error", "no-incompatible-property-type": "error", "no-unknown-property-converter": "error", "no-invalid-attribute-name": "error", "no-invalid-tag-name": "error", "no-unknown-attribute": "off", "no-unknown-event": "off", "no-unknown-slot": "off", "no-invalid-css": "off" } }] }, "include": ["src/**/*.ts"], "references": []} ``` This is a basic typescript config. Now open up `webpack.config.ts` and paste the following: ``` const HtmlWebpackInlineSourcePlugin = require("html-webpack-inline-source-plugin");const HtmlWebpackPlugin = require("html-webpack-plugin");const path = require("path");module.exports = (env, argv) => ({ mode: argv.mode === "production" ? "production" : "development", devtool: argv.mode === "production" ? false : "inline-source-map", entry: { ui: "./src/ui.ts", code: "./src/code.ts", app: "./src/my-app.ts", }, module: { rules: [{ test: /\.tsx?$/, use: "ts-loader", exclude: /node_modules/ }, { test: /\.css$/, use: ["style-loader", { loader: "css-loader" }] }, { test: /\.(png|jpg|gif|webp|svg)$/, loader: "url-loader" }, ], }, resolve: { extensions: [".ts", ".js"] }, output: { filename: "[name].js", path: path.resolve(__dirname, "dist"), }, plugins: [new HtmlWebpackPlugin({ template: path.resolve(__dirname, "ui.html"), filename: "ui.html", inject: true, inlineSource: ".(js|css)$", chunks: ["ui"], }), new HtmlWebpackInlineSourcePlugin(HtmlWebpackPlugin), ],}); ``` Now we need to create the ui for the plugin: ``` touch ui.html ``` Open up `ui.html` and add the following: ``` <my-app></my-app> ``` Now we need a manifest file for the figma plugin: ``` touch manifest.json ``` Open `manifest.json` and add the following: ``` { "name": "figma_lit_example", "id": "973668777853442323", "api": "1.0.0", "main": "code.js", "ui": "ui.html"} ``` Now we need to create our web component: ``` mkdir srccd srctouch my-app.tstouch code.tstouch ui.tscd .. ``` Open `ui.ts` and paste the following: ``` import "./my-app"; ``` Open `my-app.ts` and paste the following: ``` import { html, LitElement } from "lit";import { customElement, query } from "lit/decorators.js";@customElement("my-app")export class MyApp extends LitElement { @query("#count") countInput!: HTMLInputElement; render() { return html` <div> <h2>Rectangle Creator</h2> <p>Count: <input id="count" value="5" /></p> <button id="create" @click=${this.create}>Create</button> <button id="cancel" @click=${this.cancel}>Cancel</button> </div> `; } create() { const count = parseInt(this.countInput.value, 10); this.sendMessage("create-rectangles", { count }); } cancel() { this.sendMessage("cancel"); } private sendMessage(type: string, content: Object = {}) { const message = { pluginMessage: { type: type, ...content } }; parent.postMessage(message, "*"); }} ``` Open `code.ts` and paste the following: ``` const options: ShowUIOptions = { width: 250, height: 200,};figma.showUI( __html__ , options);figma.ui.onmessage = msg => { switch (msg.type) { case 'create-rectangles': const nodes: SceneNode[] = []; for (let i = 0; i < msg.count; i++) { const rect = figma.createRectangle(); rect.x = i * 150; rect.fills = [{ type: 'SOLID', color: { r: 1, g: 0.5, b: 0 } }]; figma.currentPage.appendChild(rect); nodes.push(rect); } figma.currentPage.selection = nodes; figma.viewport.scrollAndZoomIntoView(nodes); break; default: break; } figma.closePlugin();}; ``` ## Building the Plugin [#](#building-the-plugin) Now that we have all the code in place we can build the plugin and test it in Figma. ``` npm run build ``` #### Step 1 [#](#step-1) Download and open the desktop version of Figma. [https://www.figma.com/downloads/](https://www.figma.com/downloads/) #### Step 2 [#](#step-2) Open the menu and navigate to “Plugins > Manage plugins”  #### Step 3 [#](#step-3) Click on the plus icon to add a local plugin.  Click on the box to link to an existing plugin to navigate to the `lit-plugin` folder that was created after the build process in your source code and select `manifest.json`.  #### Step 4 [#](#step-4) To run the plugin navigate to “Plugins > Development > figma\_lit\_example” to launch your plugin.  #### Step 5 [#](#step-5) Now your plugin should launch and you can create 5 rectangles on the canvas.  If everything worked you will have 5 new rectangles on the canvas focused by figma.  ## Conclusion [#](#conclusion) If you want to learn more about building a plugin in Figma you can read more [here](https://www.figma.com/plugin-docs/intro/) and for Lit you can read the docs [here](https://lit.dev/).

## Introduction ASP.NET Core NET Core is a powerful framework for building web APIs. In this tutorial, we will walk you through creating a simple API for testing. Whether you are a beginner or looking to refresh your knowledge, this guide will help you set up a basic web API project in no time. ## Prerequisites Before we begin, ensure you have the following installed on your development machine: - Visual Studio (2019 or later) - .NET Core SDK (I am using 8 for this tutorial) ## Step-by-Step Guide to Creating a Simple ASP.NET Core API **Step 1: Create a New Web API Project** - Open Visual Studio. - Click on Create a new project. - Select the template ASP.NET Core NET Core Web API Application and click Next.  - Name your project and click Next. - Provide Additional information. I am selecting . NET 8.0 as a framework. Click Create.  - Once the project gets created. You will find one controller by default available called WeatherForecastController.  **Step 2: Create our API** - Right click on Controllers > Add > Controller. - Click on API on the left and select API Controller — Empty.  - Give it a name and click on Add. - Add the following code. I am adding one get method which is just returning “Hello World!”. ``` using Microsoft.AspNetCore.Http; using Microsoft.AspNetCore.Mvc; namespace TestApi.Controllers { [Route("api/[controller]")] [ApiController] public class TestApiController : ControllerBase { [HttpGet] public IActionResult Get() { return Ok(new { Message = "Hello, World!" }); } } } ``` **Step 3: Run the Application** - Press F5 to run the application. - You will see the Swagger UI with your API endpoints listed.  **Step 4: Test the API Endpoints** - Using the Swagger UI, you can test the endpoints. - Click on execute and it will give the data as response.  - If you want to check which URL it’s hitting then open developer tools and go to network tab. Click on execute button for the endpoint and you will see one request on the network. Click on it. On the Headers tab, you will get the Request URL. That’s the API URL.  - You can even run the URL on the new tab and it will give the response.  ## Conclusion Congratulations! You’ve successfully created a simple ASP.NET Core NET Core API for testing purposes. This basic setup can serve as a foundation for more complex APIs. Remember, practice makes perfect, so continue experimenting and building upon what you’ve learned. In the next blog, we will schedule this test API call with Hangfire. Here’s the [link](https://shekhartarare.com/Archive/2024/6/step-by-step-guide-to-scheduling-api-calls-with-hangfire) for that blog.

php, webdev, programming, javascript

As a powerful integrated [web development tool](https://www.servbay.com), ServBay comes with Composer, and its usage is very straightforward. Composer is a dependency management tool for PHP, widely used in modern PHP development. It helps developers easily manage project dependencies and automatically handle dependency relationships. With ServBay, developers can effortlessly introduce third-party libraries, manage project dependencies, and autoload class files. ### Introduction to Composer Composer is a tool for managing dependencies in PHP projects. It allows developers to declare the external libraries their project relies on and automatically install and update these libraries. Composer can manage not only PHP libraries but also other types of packages, such as frameworks and plugins. ### Main Features 1. **Dependency Management**: Composer can automatically handle project dependencies, ensuring compatibility of all library versions. 2. **Autoloading**: Composer provides an autoloading feature to help developers automatically load class files. 3. **Version Control**: Composer allows developers to specify the versions of the dependency libraries, ensuring project stability and compatibility. 4. **Package Management**: Composer can manage various types of packages, including PHP libraries, frameworks, and plugins. 5. C**ommunity Support**: Composer has a rich community resource and package repository where developers can easily find the needed libraries. ### ServBay's Built-in Composer [ServBay](https://www.servbay.com) supports multiple PHP versions and has Composer enabled by default. There is no need for additional installation steps, and developers can directly use Composer in ServBay for project management. ### Managing Project Dependencies with Composer Composer manages project dependencies through the `composer.json` file. Here are the steps to create and use a `composer.json` file. Creating the composer.json File 1. Create a `composer.json` file in the root directory of the project with the following content: ```json { "require": { "monolog/monolog": "^2.0" } } ``` 2. Run the following command to install dependencies: ```sh composer install ``` 3. Composer will download and install the needed libraries according to the dependencies specified in the `composer.json` file and generate a `vendor` directory to store these libraries. ### Autoloading Composer provides an autoloading feature to help developers automatically load class files. Here’s how to use Composer's autoloading feature. 1. Create a composer.json file in the root directory of the project with the following content: ```json { "autoload": { "psr-4": { "App\\": "src/" } } } ``` 2. Run the following command to generate the autoload files: ```sh composer dump-autoload ``` 3. Include the autoload file in the project code: ```php require 'vendor/autoload.php'; use App\MyClass; $myClass = new MyClass(); ``` ### Updating Dependencies Composer can easily update the project dependencies. Here’s how to update the dependencies. 1. Run the following command to update all dependencies: `composer update` 1. Composer will download and install the latest versions of the libraries based on the dependency information in the `composer.json` file and update the `composer.lock` file. ### Managing Composer Projects with ServBay Through ServBay, developers can more conveniently manage and use Composer for project development. Here are some tips for using Composer in ServBay: 1. **Quick Start**: ServBay comes pre-installed with Composer; developers can directly use Composer commands in the project directory without additional installation. 2. **Multiple Version Support:** ServBay supports multiple PHP versions; developers can choose the appropriate PHP version to run Composer commands. 3. **Convenient Management**: ServBay provides convenient project management tools, allowing developers to easily manage project dependencies and configurations. ### Example Project Here is an example project using Composer to manage dependencies: 1. Create a project directory and enter it: ```sh mkdir my_project cd my_project ``` 2. Create the composer.json file: ```json { "require": { "guzzlehttp/guzzle": "^7.0" } } ``` 3. Install dependencies: ```sh composer install ``` 4. Create a PHP file and use the dependency libraries: ```php <?php require 'vendor/autoload.php'; use GuzzleHttp\Client; $client = new Client(); $response = $client->request('GET', 'https://api.github.com/repos/guzzle/guzzle'); echo $response->getBody(); ``` 5. Run the PHP file: ``` php your_file.php ``` ### Conclusion ServBay provides a convenient way to manage and use Composer. With simple configurations and command operations, developers can quickly use Composer for project management in different PHP versions. The dependency management, autoloading, and version control features of Composer make it an indispensable tool in modern PHP development. With ServBay and Composer, developers can build efficient and reliable PHP applications, improving development efficiency and code quality. --- Big thanks for sticking with ServBay.

Written by Travis McPeak, Resourcely CEO. In [part 2 of this series](https://www.resourcely.io/post/death-of-devsecops-part-2), I explored the promises of DevSecOps and where they went wrong. To wrap up this series, we’ll propose how to solve the current problems in security and software development and highlight some early success cases using this approach. DevSecOps has two primary problems: we asked developers to be the primary owners of security configuration at the expense of their primary responsibilities, and we haven’t provided automation tools that can take SecOps off their plate. The result? Developers are burning down never-ending tickets, going through tedious threat modeling exercises across all of their applications, and undergoing hours of training for all vulnerability classes. ## Secure-by-default The solution is secure-by-default: an approach that shifts responsibility onto systems, not people. Secure defaults integrate security and configuration guidelines into tools that developers are using, leveraging new libraries that make security the default, all supported by a new security team. In short, systems ****should be responsible for security, not people. Secure-by-default can help developers move faster and reduce incidents by automatically taking care of secure configuration without requiring developers to make complex, nuanced decisions - and stepping in to help them, when they make incorrect ones. ## New technologies The past ~10 years of DevSecOps have taught us some valuable lessons about developer behavior: they are not security experts, and they don’t like to leave their standard development and CI workflow. To accomplish secure-by-default, any automated tooling needs to be embedded into existing developer workflows. This ranges from auto-suggesting security best practices within IDEs, to embedded context wherever configuration occurs, to using systems that make good security choices for you. Some great examples of secure default libraries and systems are: - [Netflix’s Lemur](https://github.com/Netflix/lemur): makes it easy for a developer to get a TLS certificate for a microservice, without having to deal with cryptography, manage private keys securely, and remember to rotate certs before they expire - [Google’s Safe Golang Libraries](https://bughunters.google.com/blog/4925068200771584/the-family-of-safe-golang-libraries-is-growing): protect against common issues such as YAML injection (see also [Google’s Secure by Design](https://blog.google/technology/safety-security/tackling-cybersecurity-vulnerabilities-through-secure-by-design)) - See Clint Gibbler’s full list of secure by default libraries [here](https://github.com/tldrsec/awesome-secure-defaults) The second critical part of a secure-by-default platform is guardrails: policies and rules that proactively prevent misconfiguration, again embedded into the developer’s workflow. These are backstops that prevent developers from deploying vulnerable software, while allowing them to follow their existing workflow: developing locally, pushing to the cloud, using version control, and leveraging automated deployment tooling. These embedded secure-by-default practices combine with guardrails that keep developers in track - resulting in a paved road to production. There should be paved roads across a variety of fields: infrastructure, application development, CI, and more. ## The new security team Automated tools that can take cognitive load off of developers are only possible with a savvy security team that is willing to truly embed security where developers are. This team should: - Shift from a reactive, issue-centric view of the world to a proactive, preventative strategy - Aggressively embed linters, context, and other in-IDE tech to help developers deploy securely at development time - Utilize secure by default libraries and frameworks that make classes of vulnerabilities impossible - Implement backstops and guardrails that preserve optionality by developers, while preventing incorrect configuration The foundational work of security should be done BY a security team, FOR a developer team - shifting the burden of security decision-making from developers onto systems, and making the last mile work for developers painless. These new automation technologies will allow a security team to become extensible, scaling with a development team by embedding into their workflows without having to add additional security resources and burning out developers. ## DevSecOps: Can it be saved? Security teams have lagged their developer counterparts over the past 20 years, as cloud computing and dev practices have revolutionized the tech industry. While DevSecOps held great promise, it has resulted in the worst of both worlds: slow development, and frustrated security teams dealing with constant misconfiguration. The next generation of security is secure-by-default. We have the tech, and we know what it takes to accomplish it - the only thing left is committed security teams helping embed secure-by-default into developer workflows.

https://dev.to/martabakgosong/best-practice-use-ansible-4lda

Best practices for using Ansible involve structuring your projects for scalability, maintainability, and security. Here are key recommendations: ### 1. Use a Consistent Directory Structure Organize your Ansible projects using a consistent directory structure. A typical structure might look like this: ``` production # inventory file for production servers staging # inventory file for staging environment group_vars/ group1.yml # variables for group1 group2.yml # variables for group2 host_vars/ hostname1.yml # variables for hostname1 hostname2.yml # variables for hostname2 library/ # if any custom modules, place them here (optional) module_utils/ # if any custom module_utils to support modules, place them here (optional) filter_plugins/ # if any custom filter plugins, place them here (optional) site.yml # master playbook webservers.yml # playbook for webserver tier dbservers.yml # playbook for dbserver tier roles/ common/ # this hierarchy represents a "role" tasks/ # main list of tasks to be executed by the role handlers/ # handlers, which may be used by this role or even anywhere outside this role templates/ # templates files for use within this role files/ # files for use within this role vars/ # variables associated with this role defaults/ # default lower priority variables for this role meta/ # role dependencies library/ # modules specific to this role module_utils/ # module_utils specific to this role lookup_plugins/ # lookup plugins specific to this role ``` ### 2. Use Version Control Store your Ansible playbooks and roles in a version control system (VCS) like Git. This allows you to track changes, collaborate with others, and deploy specific versions of your infrastructure. ### 3. Keep Secrets Secure Use Ansible Vault to encrypt sensitive data, such as passwords or keys, within your playbooks or variable files. Alternatively, integrate with secret management tools like HashiCorp Vault. ### 4. Use Dynamic Inventory Instead of hardcoding server IPs in your inventory files, use dynamic inventory scripts or plugins that can query your cloud providers or other sources for the current state of your infrastructure. ### 5. Leverage Roles for Reusability Organize your playbooks into roles to encapsulate and modularize the automation of common tasks. Publish and share roles via Ansible Galaxy to promote reusability across projects. ### 6. Make Playbooks Idempotent Ensure your playbooks can be run multiple times without causing errors or unintended side effects. This idempotency principle is crucial for reliability and predictability. ### 7. Use Conditional Execution Utilize Ansible's conditionals to control the execution flow of tasks based on the environment or system state. This helps in creating more flexible and adaptable playbooks. ### 8. Document Your Code Comment your playbooks and roles to explain why something is done a certain way. Use meaningful names for tasks, variables, files, and directories to enhance readability. .

In `JavaScript`, an array is a data structure that stores multiple values in a single variable. The power of JavaScript arrays comes from their built-in methods. These methods are functions that perform various operations on arrays, saving us from writing common functions from scratch. Each method has a unique purpose, such as transforming, searching, or sorting the array. **1. concat()** Combines two or more arrays. ``` let arr1 = [1, 2, 3]; let arr2 = [4, 5, 6]; let combined = arr1.concat(arr2); console.log(combined); // [1, 2, 3, 4, 5, 6] ``` **2. every()** Tests whether all elements pass the provided function. ``` let arr = [1, 2, 3, 4, 5]; let allPositive = arr.every(num => num > 0); console.log(allPositive); // true ``` **3. filter()** Creates a new array with all elements that pass the provided function. ``` let arr = [1, 2, 3, 4, 5]; let evenNumbers = arr.filter(num => num % 2 === 0); console.log(evenNumbers); // [2, 4] ``` **4. find()** Returns the first element that satisfies the provided function. ``` let arr = [1, 2, 3, 4, 5]; let found = arr.find(num => num > 3); console.log(found); // 4 ``` **5. findIndex()** Returns the index of the first element that satisfies the provided function. ``` let arr = [1, 2, 3, 4, 5]; let index = arr.findIndex(num => num > 3); console.log(index); // 3 ``` **6. forEach()** Executes a provided function once for each array element. ``` let arr = [1, 2, 3, 4, 5]; arr.forEach(num => console.log(num)); // 1 2 3 4 5 ``` **7. includes()** Determines if an array contains a certain element. ``` let arr = [1, 2, 3, 4, 5]; let hasThree = arr.includes(3); console.log(hasThree); // true ``` **8. indexOf()** Returns the first index at which a given element can be found. ``` let arr = [1, 2, 3, 4, 5]; let index = arr.indexOf(3); console.log(index); // 2 ``` **9. join()** Joins all elements into a string. ``` let arr = [1, 2, 3, 4, 5]; let str = arr.join('-'); console.log(str); // "1-2-3-4-5" ``` **10. map()** Creates a new array with the results of calling a provided function on every element. ``` let arr = [1, 2, 3, 4, 5]; let squared = arr.map(num => num * num); console.log(squared); // [1, 4, 9, 16, 25] ``` **11. pop()** Removes the last element and returns it. ``` let arr = [1, 2, 3, 4, 5]; let last = arr.pop(); console.log(last); // 5 console.log(arr); // [1, 2, 3, 4] ``` **12. push()** Adds one or more elements to the end and returns the new length. ``` let arr = [1, 2, 3, 4]; arr.push(5); console.log(arr); // [1, 2, 3, 4, 5] ``` **13. reduce()** Executes a reducer function on each element, resulting in a single output value. ``` let arr = [1, 2, 3, 4, 5]; let sum = arr.reduce((accumulator, currentValue) => accumulator + currentValue, 0); console.log(sum); // 15 ``` **14. reverse()** Reverses the array in place. ``` let arr = [1, 2, 3, 4, 5]; arr.reverse(); console.log(arr); // [5, 4, 3, 2, 1] ``` **15. shift()** Removes the first element and returns it. ``` let arr = [1, 2, 3, 4, 5]; let first = arr.shift(); console.log(first); // 1 console.log(arr); // [2, 3, 4, 5] ``` **16. slice()** Returns a shallow copy of a portion of an array into a new array. ``` let arr = [1, 2, 3, 4, 5]; let sliced = arr.slice(1, 3); console.log(sliced); // [2, 3] ``` **17. some()** Tests whether at least one element passes the provided function. ``` let arr = [1, 2, 3, 4, 5]; let hasEven = arr.some(num => num % 2 === 0); console.log(hasEven); // true ``` **18. sort()** Sorts the elements in place. ``` let arr = [5, 2, 1, 4, 3]; arr.sort(); console.log(arr); // [1, 2, 3, 4, 5] ``` **19. splice()** Changes the contents by removing or replacing existing elements and/or adding new elements. ``` let arr = [1, 2, 3, 4, 5]; arr.splice(2, 1, 'a', 'b'); console.log(arr); // [1, 2, 'a', 'b', 4, 5] ``` **20. toString()** Returns a string representing the array. ``` let arr = [1, 2, 3, 4, 5]; let str = arr.toString(); console.log(str); // "1,2,3,4,5" ``` **21. unshift()** Adds one or more elements to the beginning and returns the new length. ``` let arr = [2, 3, 4, 5]; arr.unshift(1); console.log(arr); // [1, 2, 3, 4, 5] ``` **22. flat()** Creates a new array with all sub-array elements concatenated into it. ``` let arr = [1, 2, [3, 4], [5, 6]]; let flattened = arr.flat(); console.log(flattened); // [1, 2, 3, 4, 5, 6] ``` **23. flatMap()** First maps each element using a mapping function, then flattens the result into a new array. ``` let arr = [1, 2, 3]; let mapped = arr.flatMap(num => [num, num * 2]); console.log(mapped); // [1, 2, 2, 4, 3, 6] ``` **24. from()** Checks if the passed value is an array. ``` let str = 'hello'; let arr = Array.from(str); console.log(arr); // ['h', 'e', 'l', 'l', 'o'] ``` **25. isArray(** Checks if the passed value is an array. ``` console.log(Array.isArray([1, 2, 3])); // true console.log(Array.isArray('hello')); // false ``` **26. of()** Creates a new array instance with a variable number of arguments. ``` let arr = Array.of(1, 2, 3); console.log(arr); // [1, 2, 3] ``` If you need more detailed explanations or additional methods, feel free to ask!

 Maintaining security, functionality, and access to new features calls for updating your WooCommerce store. However, because you're concerned with possible issues and downtime that might impact your store and upset consumers, the process can be stressful. Fortunately, you may upgrade WooCommerce safely and prevent downtime by taking the proper precautions. We'll walk you through five simple steps in this blog post to make sure the update process works smoothly. By following these steps, you can continue to enjoy continuous use of the most recent improvements while preserving the features of your WooCommerce store. Now let's get going! ## 1. Pre-Update Checklist Prior to updating the WooCommerce plugin, make sure the following conditions are satisfied. Let's examine each one in turn: Backup Your Site: Making a complete backup of your website is the first step. Taking this precaution is essential in the event that WooCommerce updates cause problems. Test and Review: To ensure that the update is fully tested, set up a staging environment. Before deploying the update to your live website, make sure everything functions as it should. Verify if a plugin is compatible: Make sure that the current version of WooCommerce is compatible with the other plugins you have. Additionally, certain plugins may require upgrades. Update Plugins and Themes: To guarantee improved compatibility, update your other plugins and themes concurrently with WooCommerce. Notify Customers: As soon as the update is complete, let your customers know if your store was briefly closed. ## 2. Test the Updated WooCommerce on the Staging site Check the site thoroughly after completing the WooCommerce update. Examine the contact page, cart page, checkout page, and home page. Furthermore, make sure the WooCommerce-dependent plugins—like WooCommerce Payment and WooCommerce Memberships—are operating correctly by looking over them. You might think about hiring **[WooCommerce development services](https://www.saffiretech.com/custom-woocommerce-development/)** if you need a custom plugin, such as for payment or shipment. Skilled WooCommerce developers are able to design and refine distinctive plugins so that they are free of issues. The most important one is to update the WooCommerce plugin on the operating website. Since you already backing up the website and can restore it if required, don't worry about any possible issues. Now let's get started! ## 3. Update WooCommerce on the live site After finishing the WooCommerce updates, go back and repeat each step on your live website. Once WooCommerce has been upgraded on the live site, carefully examine your website for any potential issues. Examine the payment process, cart, and homepages with caution. Make that the WooCommerce theme and your plugins work correctly with the most current version of WooCommerce. **Key Notes** WooCommerce updates frequently to fix potential bugs and issues. But updating WooCommerce without following appropriate safety measures can endanger your website. It's essential to be ready for these upgrades as they can come at any moment. Always maintain a copy of your WooCommerce website to ensure safety. To guarantee a seamless transition, test each important plugin update on a staging site before making the update.

Fri, Jul 5, 2024 Yesterday being Independence Day, I took some time off to catch up with family and friends. Last night's Phoenix AZ skies were crystal clear for a spectacular view of fireworks. Codecademy certainly covers CSS thoroughly; I definitely noted that element positioning is thoroughly explored, including Z-Index and floats, which I understand used to be common, and many of us will be responsible for maintaining existing code bases, so it's good to see it now. Onto next lesson, Deploying Websites Locally, and seeing what that brings.

Why we use LINK tag instead of <a> in REACTJS

https://dev.to/tushar_pal/why-we-use-link-tag-instead-of-in-reactjs-8h3

javascript, react, basic, beginners

## Why We Use the `Link` Tag of `react-router-dom` Instead of the `a` Tag in JSX Files When building a ReactJS application, navigating between pages is a crucial aspect of the user experience. However, the way we navigate between pages can have a significant impact on the performance and user experience of our application. In this article, we'll explore why we should use the `Link` component from `react-router-dom` instead of the plain HTML `a` tag in our JSX files. ### The Problem with the `a` Tag When we use a plain HTML `a` tag to navigate between pages, the browser performs a full page reload. This means that the browser sends a request to the server, which responds with a new HTML page. This process involves a full page reload, which can be slower and less efficient than client-side routing. Here is an example of using the `a` tag in a React component: ```jsx import React from 'react'; function Home() { return ( <div> <h1>Home Page</h1> <a href="/about">Go to About Page</a> </div> ); } export default Home; ``` In this example, clicking the "Go to About Page" link will cause a full page reload as the browser requests the `/about` page from the server. ### The Advantages of `react-router-dom` On the other hand, when we use the `Link` component from `react-router-dom`, it doesn't trigger a full page reload. Instead, it uses JavaScript to update the URL in the browser's address bar and render the new page content without requesting a new HTML page from the server. But remember Link tag is just a wrap up over < a > you can see this in chrome developer tools Here are some advantages of using `react-router-dom`: 1. **Client-side routing**: `react-router-dom` handles routing entirely on the client-side, which means that the browser updates the URL without requesting a new page from the server. 2. **JavaScript-based navigation**: `react-router-dom` uses JavaScript to navigate between pages, which allows for a faster and more efficient navigation experience. 3. **No server request**: Because `react-router-dom` handles routing on the client-side, it doesn't send a request to the server when you navigate between pages, which means that the page doesn't reload. ### The Disadvantages of Full Page Reloads Full page reloads can have several disadvantages, including: 1. **Loss of State**: When the page reloads, the entire application state is lost, which means that any unsaved data, user input, or temporary state is discarded. 2. **Poor User Experience**: Page reloads can be jarring and disrupt the user's flow, leading to a poor user experience. 3. **Slower Performance**: Page reloads can be slower than client-side routing, which can negatively impact the application's performance. ### Using the `Link` Tag from `react-router-dom` First, ensure you have `react-router-dom` installed: ```bash npm install react-router-dom ``` Then, you can use the `Link` component like this: ```jsx import React from 'react'; import { BrowserRouter as Router, Route, Switch, Link } from 'react-router-dom'; function Home() { return ( <div> <h1>Home Page</h1> <Link to="/about">Go to About Page</Link> </div> ); } function About() { return ( <div> <h1>About Page</h1> <Link to="/">Go to Home Page</Link> </div> ); } function App() { return ( <Router> <Switch> <Route exact path="/" component={Home} /> <Route path="/about" component={About} /> </Switch> </Router> ); } export default App; ``` In this example: - The `Router` component wraps the entire application to enable routing. - The `Link` component is used for navigation instead of the `a` tag. - The `Switch` component ensures that only one route is rendered at a time. - The `Route` components define the paths and corresponding components to render. ### Conclusion Using the `Link` component from `react-router-dom` instead of the plain HTML `a` tag in your JSX files is essential for creating a smooth and efficient navigation experience in your ReactJS application. By leveraging client-side routing, you can avoid full page reloads, maintain application state, and provide a better overall user experience. ---

opensource, github, security, cybersecurity

In an age where cybersecurity is paramount, finding the right two-factor authentication (2FA) method can mean the difference between a secure online presence and a vulnerable one. Let's delve into the realm of 2FA and compare different methods to help you safeguard your digital identity effectively. **<u>The Rise of Two-Factor Authentication</u>** Two-factor authentication has become a standard in securing online accounts beyond just passwords. By adding an extra layer of verification, 2FA significantly reduces the risk of unauthorized access, even if your password is compromised. However, not all 2FA methods are created equal. **<u>SMS: Convenience vs. Vulnerability</u>** Initially popular, SMS-based 2FA sends a code to your mobile device, which you enter to access your account. While convenient, SMS can be vulnerable to SIM swapping attacks, where hackers take over your phone number to intercept codes. **<u>Authenticator Apps: Balancing Security and Accessibility</u>** Authenticator apps like VerifyVault generate codes offline, which adds a layer of security compared to SMS. These apps are widely supported and generally easy to use, making them a popular choice for many users. **<u>Hardware Tokens: The Fort Knox of 2FA</u>** For ultimate security, hardware tokens provide a physical device that generates one-time passcodes. They are immune to phishing attacks and malware, but can be costly and less convenient than other methods. **<u>Introducing VerifyVault: Your New 2FA Guardian</u>** If you're looking for a robust, free, and open-source 2FA solution, look no further than VerifyVault. Designed for Windows and soon Linux users, VerifyVault offers encrypted, offline, and password-protected authentication. Its features include automatic backups, password reminders, and easy account import/export via QR codes. _Start securing your accounts with VerifyVault and experience the peace of mind that comes with top-notch cybersecurity._ Choosing the right 2FA method depends on balancing security, convenience, and accessibility. While SMS is widely available, authenticator apps offer a better compromise between usability and security. For those needing ironclad protection, hardware tokens remain unmatched. **<u>Downloads</u>** [Repository](https://github.com/VerifyVault) [Direct Download to v0.3](https://github.com/VerifyVault/VerifyVault/releases/tag/Beta-v0.3)

github, community, news, developers

We've hit the halfway point of 2024. While some are catching rays on the beach or snow on the mountains—depending on your hemisphere— developer heroes are grinding away on their open source projects, shipping major updates. These hard working coders are building everything from fun side hassles, to ground breaking technology. Let's take a look at our staff picks for this month's Release Radar; a roundup of the open source projects that have shipped major version updates. ## Simple Data Analysis 3.0 SDA—or [Simple Data Analysis](https://github.com/nshiab/simple-data-analysis)—is a high-performance JavaScript library for data analysis. The new update makes it easier to use process tabular and geospatial data. It operates seamlessly in the browser and the team behind SDA used it to tackle the 1 Billion Row Challenge—impressive stuff 😮. ## FakeRest 4.0 Want a browser library that intercepts AJAX calls to mock a REST server based on JSON data? Then look no further than [FakeRest](https://github.com/marmelab/FakeRest). The new update has a tonne of new features including added support for Mock Service Worker (MSW), string identifiers, custom ID generation, and many more abilities. Check out the [release notes](https://github.com/marmelab/FakeRest/releases/tag/v4.0.0) for all the changes. ## React-admin 5.0 Whenever I see the word "framework", I can't help but think of [the Linebreakers' song "We're Gonna Build a Framework"](https://www.youtube.com/watch?v=pgrGSnC3SKE). That aside, [React-admin](https://marmelab.com/react-admin/) has over 25,000 users around the world. It's a single-page application framework, allowing you to build web apps running on top of REST/GraphQL APIs, using TypeScript, React and Material Design. React-admin's [latest update](https://github.com/marmelab/react-admin/releases/tag/v5.0.0) brings refined lists and forms, dependency update, and easier application initialisation.  ## Goyave 5.0 More frameworks! We all love frameworks. This one is an opinionated all-in-one Golang web framework. [Goyave](https://goyave.dev/) is focused on REST APIs, with emphasis on code reliability, maintainability and developer experience. With the newest version, Goyave has been redesigned and rewritten from the ground up. It now takes advantage of the modern language features. Read up on all the changes in their [extensive release notes](https://github.com/go-goyave/goyave/releases/tag/v5.0.0). ## Keuss 2.0 A serverless, persistent and highly-available queue middleware. That's what [Keuss](https://github.com/pepmartinez/keuss) is. It's built on Node.js, supports delays/schedule, and currently supports MongoDB, Redis and PostgreSQL. The latest release adds a new major backend, allowing Keuss to support queues over PostgreSQL databases. Check out the [changelog for all the updates](https://pepmartinez.github.io/keuss/docs/changelog/). ## Node-RED 4.0 Want a low code application for event-driven applications? Then [Node-RED](https://nodered.org/) is your go to. The new update brings a breaking change, with Node-RED now requiring Node 18.x or later. The team have added new features and updated dependencies to the editor, and there are lots of fixes within the editor. Check out the [release notes for all the details](https://github.com/node-red/node-red/releases/tag/4.0.0).  ## DuckDB 1.0 What do ducks and databases have in common? They are both fast, reliable, and portable. Okay, maybe ducks aren't like that, but [DuckDB](http://duckdb.org/) is :duck:.

Automate User Management on Linux with a Bash Script

Managing users and groups on a Linux system can be a repetitive and error-prone task, especially in...

https://dev.to/shirley_5e2405f86bcff245a/automate-user-management-on-linux-with-a-bash-script-1i60

Managing users and groups on a Linux system can be a repetitive and error-prone task, especially in environments where users frequently join or leave the system. In this article, I'll walk you through creating a Bash script that automates user and group management, ensuring secure password handling and detailed logging. This task is part of the HNG Internship, a fantastic program that helps interns gain real-world experience. You can learn more about the program at the [HNG Internship website](https://hng.tech/internship) or consider hiring some of their talented interns through the [HNG Hire page](https://hng.tech/hire). The source code can be found on my [GitHub] (https://github.com/nthelma30/Create_User.sh.git) #### Introduction User management is a critical task for system administrators. Automating this process not only saves time but also reduces the risk of errors. This script will: - Create users from an input file. - Assign users to specified groups. - Generate secure random passwords. - Log all actions for auditing purposes. #### Prerequisites - A Linux system with Bash shell. - `sudo` privileges to execute administrative commands. - `openssl` for generating random passwords. #### Script Breakdown Here's the script in its entirety: ```bash #!/bin/bash # Check if the input file exists if [ ! -f "$1" ]; then echo "Error: Input file not found." exit 1 fi # Ensure log and secure directories are initialized once LOG_FILE="/var/log/user_management.log" PASSWORD_FILE="/var/secure/user_passwords.csv" # Initialize log file if [ ! -f "$LOG_FILE" ]; then sudo touch "$LOG_FILE" sudo chown root:root "$LOG_FILE" fi # Initialize password file if [ ! -f "$PASSWORD_FILE" ]; then sudo mkdir -p /var/secure sudo touch "$PASSWORD_FILE" sudo chown root:root "$PASSWORD_FILE" sudo chmod 600 "$PASSWORD_FILE" fi # Redirect stdout and stderr to the log file exec > >(sudo tee -a "$LOG_FILE") 2>&1 # Function to check if user exists user_exists() { id "$1" &>/dev/null } # Function to check if a group exists group_exists() { getent group "$1" > /dev/null 2>&1 } # Function to check if a user is in a group user_in_group() { id -nG "$1" | grep -qw "$2" } # Read each line from the input file while IFS=';' read -r username groups; do # Trim whitespace username=$(echo "$username" | tr -d '[:space:]') groups=$(echo "$groups" | tr -d '[:space:]') # Check if the user already exists if user_exists "$username"; then echo "User $username already exists." else # Create user sudo useradd -m "$username" # Generate random password password=$(openssl rand -base64 12) # Set password for user echo "$username:$password" | sudo chpasswd # Log actions echo "User $username created. Password: $password" # Store passwords securely echo "$username,$password" | sudo tee -a "$PASSWORD_FILE" fi # Ensure the user's home directory and personal group exist sudo mkdir -p "/home/$username" sudo chown "$username:$username" "/home/$username" # Split the groups string into an array IFS=',' read -ra group_array <<< "$groups" # Check each group for group in "${group_array[@]}"; do if group_exists "$group"; then echo "Group $group exists." else echo "Group $group does not exist. Creating group $group." sudo groupadd "$group" fi if user_in_group "$username" "$group"; then echo "User $username is already in group $group." else echo "Adding user $username to group $group." sudo usermod -aG "$group" "$username" fi done done < "$1" ``` #### How It Works 1. **Input File Check**: The script starts by checking if the input file exists. If not, it exits with an error message. 2. **Log and Secure File Initialization**: It initializes the log and password files, ensuring they have the correct permissions. 3. **Function Definitions**: Functions to check user existence, group existence, and user membership in a group are defined. 4. **User and Group Processing**: The script reads the input file line by line, processes each username and group, creates users and groups as needed, and assigns users to groups. 5. **Password Handling**: Secure random passwords are generated and assigned to new users, and all actions are logged. #### Running the Script 1. **Prepare the Input File**: Create a file named `input_file.txt` with the following format: ``` alice;developers,admins bob;developers charlie;admins,users ``` 2. **Make the Script Executable**: ```sh chmod +x user_management.sh ``` 3. **Run the Script**: ```sh sudo ./user_management.sh input_file.txt ``` #### Conclusion This Bash script simplifies user management on Linux systems, ensuring users are created with secure passwords, assigned to appropriate groups, and all actions are logged for audit purposes. By automating these tasks, system administrators can save time and reduce errors. Feel free to customize this script further to suit your specific needs. Happy automating! #### About the Author Shirley Gwata is a seasoned DevOps engineer with extensive experience in automating system administration tasks. Follow Shirley Gwata on [GitHub](https://github.com/shirley-007) for more insightful articles and projects. --- These comprehensive README and article drafts should help you document and share your user management script effectively across different platforms.

https://dev.to/jessmar/how-i-bought-a-mitsubishi-1lp4

San Francisco, the city of fog and hills, decided to give me a taste of an unexpected heatwave. I’m talking about temperatures that could make a polar bear rethink its life choices. My quaint little house, usually a cool refuge from the bustling city, turned into a sauna. Even the cat started giving me dirty looks, as if to say, "Do something, human." It all began one sweltering Monday. I dragged myself home from work, peeling off my sweaty clothes like they were made of Velcro. I stood in front of my open fridge, fantasizing about moving into it. My home was so hot that I seriously considered setting up a tent on the Golden Gate Bridge just to catch some breeze. The situation was unbearable. I avoided coming home. I started spending extra hours at work just to bask in the glory of their industrial-strength AC. My boss thought I had turned over a new leaf. Little did he know, it wasn’t dedication driving me—it was desperation. One day, while sipping on an iced coffee in the office, my friend Jake, who has a knack for finding solutions to life's most absurd problems, popped by my desk. He noticed the beads of sweat forming on my forehead and said, "Man, you look like you’re melting." “No kidding, Sherlock. My house has turned into an oven,” I replied, fanning myself with a file. Jake, always the fixer, leaned in and whispered like he was sharing a top-secret government code, "You need to call [GALAXY Heating and Cooling](https://galaxyservices.com/). They’ll hook you up with a [Mitsubishi cooling system](https://www.mitsubishicomfort.com/)." “A Mitsubishi? I thought they made cars,” I said, picturing a sedan parked in my living room with the AC cranked up. “No, no,” Jake chuckled. “They make these amazing cooling systems. Trust me, it’ll change your life.” I was skeptical, but desperate times call for desperate measures. That evening, I called GALAXY Heating and Cooling. Their representative, Sarah, sounded like she was sitting in a cool, breezy paradise as she assured me, “We’ll have you feeling like you’re living in an igloo in no time.” Two days later, a couple of GALAXY techs arrived at my place, armed with tools and a Mitsubishi cooling system that looked like it was designed by NASA. They worked swiftly and efficiently, despite the heat. I provided them with an endless supply of iced tea, partially out of gratitude and partially out of the hope they wouldn’t abandon me in my hour of need. By the time they were done, my house had transformed from a fiery pit of doom into a cool, refreshing oasis. The first blast of chilled air hit me, and I felt like I had ascended into an air-conditioned heaven. My cat, who had been glaring at me from her perch, immediately forgave me and settled down in front of the vent, purring contentedly. That night, I slept like a baby. No more tossing and turning in a pool of my own sweat. I woke up feeling like a new person, rejuvenated and ready to face the world. I even contemplated inviting my boss over, just to show him my newfound commitment to comfort. Weeks passed, and I started hosting dinner parties, inviting friends who were also suffering in the heat. My place became the go-to spot, the epitome of coolness in more ways than one. All thanks to that Mitsubishi system from GALAXY Heating and Cooling. So, here I am, living the dream in San Francisco, all because I bought a Mitsubishi. Who knew that a cooling system could bring so much happiness and transform a home from a hellish furnace into a frosty paradise? If you’re ever roasting in your own house, take my advice: call GALAXY Heating and Cooling and get yourself a Mitsubishi. Your cat will thank you.

GetOwnPropertyDescriptor - Throught this key we can control our objects properties. For example these keys controlled by users if it should be - Configurable, Enumerable, Writable.  ``` let change={ name:'Arda', theme:'Magic' } let result=Object.getOwnPropertyDescriptor(change, 'name'); console.log(result); ``` ## Writable it is possable to type value again if we put true. ## Enumerable Throught this value we can control loops - for in and for of works or not. ## Configurable This key can remove and change object values. ## DefineProperty This method also give pirmession or not to change object ``` let change={ name:'Arda', theme:'Magic' } Object.defineProperty(change, 'theme', { value:"Netlify", enumerable:false, writable:false, configurable:false }); change.smth='ok' console.log(change); for(let key in change){ console.log('new',change[key]); } ```  in this case we change object theme to Netlify and use for in and show each property and finally we should say that if we have not to change we will control it from js.

https://dev.to/apidna/data-consistency-and-integrity-in-api-integration-b76

data, api, security, webdev

With such large volumes of data being exchanged between APIs, data consistency and integrity are essential to consider when integrating APIs. Without these, the promise of seamless integration can quickly turn into a chaotic, error-prone mess. Data consistency ensures that data remains uniform and coherent across all systems, while data integrity guarantees that the information is accurate, reliable, and trustworthy. These concepts are critical to ensuring that integrated systems function correctly and efficiently. This article highlights the vital aspects of data consistency and integrity within API integration. We will explore the fundamental principles, examine the dire consequences of compromised data, and highlight the differences between data validation and verification. Additionally, we will provide best practices and strategies for handling JSON and XML data formats, discuss error detection and correction methods, and outline how robust integration architecture supports data integrity. ## Key Concepts: Data Integrity and Data Consistency In API integration, ensuring data integrity means that the data exchanged between systems remains unaltered and trustworthy, preserving its original meaning and value. This is critical in scenarios such as financial transactions, where incorrect data can lead to significant losses, or in healthcare, where it can result in life-threatening errors.  Data consistency ensures that all systems involved interpret and display data in the same way, preventing discrepancies that could disrupt operations. For example, in a multi-platform e-commerce application, data consistency guarantees that inventory levels are accurately reflected across the website, mobile app, and backend systems simultaneously. ## The Impact of Data Integrity Failures Compromised data integrity can have severe consequences for any business, leading to operational errors that disrupt business functions and impair decision-making. When data is inaccurate or unreliable, it can cause significant issues such as incorrect inventory levels, erroneous financial reports, and flawed business strategies.  Continuing from our previous examples, consider a financial application processing transaction data. Without proper integrity checks, inaccurate data can lead to financial losses, erroneous tax calculations, and misinformed investment decisions. Similarly, in healthcare systems, compromised patient records can result in incorrect diagnoses, inappropriate treatments, and potentially life-threatening mistakes. ## Why Both Validation and Verification Matter in API Integration Data validation ensures that data conforms to predefined rules and structures before it is processed or stored. This step is essential in API integration, as it prevents incorrect or malformed data from entering the system, thereby reducing errors and maintaining data quality. Here are some of the key validation techniques: - **Schema Enforcement:** Utilising schemas, such as JSON Schema or XML Schema Definition (XSD), to define the structure and format of data. Schemas ensure that incoming data matches expected patterns, preventing format-related errors. We’ll discuss these in more detail in the next section. - **Data Type Checks:** Verifying that data types (e.g., integers, strings, dates) are correct and consistent. This avoids issues caused by incompatible or unexpected data types. - **Business Logic Validation:** Implementing custom rules specific to the application’s requirements, ensuring data aligns with business logic. For example, validating that a “quantity” field is a positive integer or that a “date” field falls within a certain range.  While data validation focuses on ensuring data meets certain criteria, data verification confirms the accuracy and correctness of the data after it has been collected. This step is crucial for identifying and rectifying inconsistencies in data that might have passed initial validation but are still flawed. Key verification techniques include: - **Data Cleansing:** Identifying and correcting inaccuracies or incomplete data. Techniques such as outlier detection and normalisation help clean the data before further processing or storage. - **Data Reconciliation:** Comparing data from different sources to identify and resolve discrepancies. Automated reconciliation processes highlight disparities, enabling timely corrections to ensure consistency. - **Data Profiling:** Analysing data characteristics and identifying anomalies through profiling tools. This proactive approach helps detect potential issues early, providing a deeper understanding of the data and maintaining its integrity. ## Data Formats As mentioned previously, JSON and XML are two prevalent schemas or formats in API communication. Each of them require specific validation techniques to maintain data quality and consistency. ### JSON JSON Schema defines the expected structure of JSON documents, specifying required fields, data types, and value constraints. This ensures that any incoming data adheres to the predefined standards, preventing malformed data from entering the system. In a financial API, a JSON Schema can enforce that a “transaction_amount” field must be a positive number and a “transaction_date” must follow a specific date format. This pre-validation helps maintain data accuracy and integrity before any processing occurs. It is critical to ensure that all schemas are up-to-date and reflect the latest API specifications. You can use automated tools, such as the APIDNA platform, to validate JSON data against schemas during integration. Our autonomous agent powered platform takes care of mundane data formatting tasks, so you can focus on innovation. [Click here](https://apidna.ai/) to try our platform today, and begin your journey to simplify API integrations.  ### XML XSD provides a way to define and validate the structure and content of XML documents. By specifying element types, attributes, and data constraints, XSD ensures that XML data is correctly formatted and adheres to expected patterns. In a healthcare API, an XSD can ensure that an “patient_id” element is always an integer and that a “date_of_birth” element follows a standardised date format. Make sure to regularly update XSDs to match evolving data requirements. Employ robust XML parsers to validate data integrity against XSDs. ## Best Practices for Ensuring Data Consistency and Integrity Implementing the following best practices ensures that data remains accurate, secure, and consistent across systems: - **Schema Enforcement and Data Type Checks:** Enforcing schemas, such as JSON Schema and XML Schema Definition (XSD), is fundamental for validating the structure and format of data. - **Business Logic Validation:** Beyond basic schema enforcement, it’s crucial to implement custom validation rules that reflect business logic. This ensures that data not only meets technical specifications but also aligns with specific business requirements. - **Versioning and Tracking Data Changes:** Tracking changes through versioning and timestamps is vital for maintaining historical records and auditing purposes. Versioning allows you to manage different iterations of data structures, ensuring compatibility and traceability. Timestamps help track data modifications, facilitating error analysis and compliance checks.  - **Encryption and Securing Sensitive Data:** Protecting sensitive data is paramount. Encrypting data both at rest and in transit adds an essential layer of security. Employ strong encryption algorithms to safeguard confidential information, reducing the risk of unauthorised access and data breaches. - **Error Handling and Logging:** Comprehensive error handling mechanisms are essential for quickly identifying and resolving data issues. Implement detailed logging to capture data errors and anomalies. These logs provide valuable insights into the root causes of discrepancies, enabling timely corrective actions and continuous improvement. To learn more about API error handling, check out our [previous article here](https://apidna.ai/api-error-handling-techniques-and-best-practices/). - **Monitoring and Alerting for Continuous Data Quality Assurance:** Continuous monitoring of data quality, coupled with alerting systems, ensures proactive identification of potential issues. Setting up alerts for anomalies or deviations from expected patterns allows for swift intervention, minimising operational disruptions. ## Further Reading [Data Integrity Best Practices & Architecture Strategies – KMS Technology](https://kms-technology.com/software-development/data-integrity-strategies.html) [How to ensure Data Integrity and consistency in APIs – APItoolkit](https://apitoolkit.io/blog/how-to-ensure-data-integrity-and-consistency-in-apis/)

https://devdojo.com/bobbyiliev/how-to-make-parent-div-activate-styling-of-child-div-for-hover-and-active-states

tailwindcss, css, webdev, beginners

Hey there developers! 👋 Today, we're diving into a Tailwind CSS trick! We'll explore how to make a parent div control the styling of its child elements on hover and active states. Let's jump right in! ## The Problem You've probably encountered situations where you want an entire component to respond to user interactions, not just individual elements. For example, you might want a card to change its appearance when hovered, including all its child elements. Tailwind CSS has a elegant solution for this: the `group` and `group-hover` utilities. ## The Solution: Group and Group-Hover Tailwind CSS provides a powerful feature called "group hover" that allows us to style child elements based on the state of a parent element. Here's how it works: 1. Add the `group` class to your parent element. 2. Use `group-hover:` prefix on child elements to apply styles when the parent is hovered. Let's see this in action with a cool example: ```html <div class="group p-6 bg-gray-100 rounded-lg transition-all duration-300 hover:bg-blue-100"> <h2 class="text-2xl font-bold text-gray-800 group-hover:text-blue-600">Awesome Feature</h2> <p class="mt-2 text-gray-600 group-hover:text-blue-500">This feature will blow your mind!</p> <button class="mt-4 px-4 py-2 bg-blue-500 text-white rounded group-hover:bg-blue-600"> Learn More </button> </div> ``` In this example, when you hover over the parent `div`, the heading, paragraph, and button all change color simultaneously. Pretty cool, right? ## Taking It Further: Group-Active But wait, there's more! We can also use the `group-active` variant to style child elements when the parent is in an active state (e.g., being clicked). Here's an enhanced version of our previous example: ```html <div class="group p-6 bg-gray-100 rounded-lg transition-all duration-300 hover:bg-blue-100 active:bg-blue-200"> <h2 class="text-2xl font-bold text-gray-800 group-hover:text-blue-600 group-active:text-blue-800">Awesome Feature</h2> <p class="mt-2 text-gray-600 group-hover:text-blue-500 group-active:text-blue-700">This feature will blow your mind!</p> <button class="mt-4 px-4 py-2 bg-blue-500 text-white rounded group-hover:bg-blue-600 group-active:bg-blue-800"> Learn More </button> </div> ``` Now, when you click on the component, you'll see an additional style change. It's like magic, but it's just the power of Tailwind CSS! 🎩✨ ## Pro Tip: Extending Core Plugins It's worth noting that not every property supports `group-hover` or `group-active` out of the box. In some cases, you might need to extend Tailwind's core plugins. You can do this in your `tailwind.config.js` file: ```javascript module.exports = { // ...other config plugins: [ plugin(({ addVariant }) => { addVariant('group-hover', ':merge(.group):hover &') addVariant('group-active', ':merge(.group):active &') }) ], } ``` This will allow you to use `group-hover` and `group-active` with any utility in Tailwind CSS. ## Wrapping Up And there you have it! You've just learned how to make parent divs control the styling of their child elements for hover and active states using Tailwind CSS. As a next step, check out DevDojo's Tails page builder at [https://devdojo.com/tails/](https://devdojo.com/tails/). It's a fantastic visual builder that lets you create stunning Tailwind CSS powered pages with ease. Give it a spin and see how it can supercharge your development workflow! Keep coding, stay curious, and until next time, may your builds be bug-free and your coffee strong! 💻☕️

_Elevate your conversational AI experience with our Multimodal Chat feature. Seamlessly integrate advanced multimodal capabilities into your applications to enhance user interactions and provide a richer, more engaging experience.‍_ ## What is Multimodal AI? Multimodal AI refers to artificial intelligence systems that can process and integrate information from multiple modalities or sources of data, such as text, images, audio, video, and sensor data. The goal of multimodal AI is to combine and leverage information from these different sources to improve understanding, decision-making, and task performance. Some key aspects of multimodal AI include: - Enhanced Understanding: Combining different types of data allows AI to form a richer, more complete understanding of the context. For example, a system that analyzes both video and audio can better understand the emotions and actions of people in a scene. - Improved Performance: Multimodal AI often performs better on complex tasks than unimodal systems (those that process only one type of data). This is because it can leverage complementary information from different sources. - Robustness: By relying on multiple data sources, multimodal AI systems can be more robust and less prone to errors. If one modality is noisy or missing, other modalities can help fill in the gaps. - Natural Interaction: Multimodal AI enables more natural and intuitive human-computer interactions.

ai, ollama, python

In today’s tech-driven world, automation is revolutionizing recruitment. Imagine having a virtual IT interviewer that not only interacts intelligently but also communicates verbally with candidates. This post will guide you through building an IT interviewer using Ollama and Python, integrating audio capabilities for a more immersive experience. **📚 Introduction** Finding the right talent can be challenging and time-consuming. With advancements in AI and audio processing, it's possible to automate the initial interview phase. This project showcases how to create an interactive IT interviewer that asks questions and processes answers through voice, using Ollama and Google Cloud's Speech-to-Text and Text-to-Speech APIs. **🚀 What You Will Learn** - How to set up Ollama for conversation handling. - Integrate Google Cloud’s Speech-to-Text and Text-to-Speech APIs for audio capabilities. - Structure a Python project to automate interviews. **🛠️ Prerequisites** - Python 3.7+ - Google Cloud Account: For Speech-to-Text and Text-to-Speech APIs. - Ollama Account: For conversational AI. **📂 Project Setup** **1. Clone the Repository** Start by cloning the project repository: ``` git clone https://github.com/josmel/ollama-it-interviewer.git cd ollama-it-interviewer ``` **2. Create and Activate a Virtual Environment** Set up a virtual environment to manage dependencies: ``` python -m venv venv source venv/bin/activate ``` **3. Install Dependencies** Install the required Python packages: ``` pip install -r requirements.txt ``` **4. Configure Google Cloud** _a. Enable the APIs_ Enable the Speech-to-Text and Text-to-Speech APIs in your Google Cloud Console. _b. Create Service Account and Download JSON Key_ 1. Go to IAM & Admin > Service accounts. 2. Create a new service account, grant it the necessary roles, and download the JSON credentials file. _c. Set the Environment Variable_ Set the environment variable to point to your credentials file ``` export GOOGLE_APPLICATION_CREDENTIALS="/path/to/your/service-account-file.json" ``` Replace `/path/to/your/service-account-file.json` with the actual path to your credentials file. 5. Prepare Audio Files Add sample audio files in the audio_samples/ directory. You need a candidate-response.mp3 file to simulate a candidate's response. You can record your voice or use text-to-speech tools to generate this file. 6. Update Configuration Edit src/config.py to configure your Ollama credentials: ``` OLLAMA_API_URL = 'https://api.ollama.com/v1/conversations' # Or replace with your Ollama local OLLAMA_MODEL = 'your-ollama-model' # Replace with your Ollama model ``` **7. Run the Project** Run the interviewer script: ``` # Option 1: Run as a module from the project root python3 -m src.interviewer ``` or ``` # Option 2: Ensure PYTHONPATH is set and run directly export PYTHONPATH=$(pwd) python3 src/interviewer.py ``` **📝 Detailed Explanation** `interviewer.py` The main script orchestrates the interview process: ``` from pydub import AudioSegment from pydub.playback import play from src.ollama_api import ask_question from src.speech_to_text import recognize_speech from src.text_to_speech import synthesize_speech from dotenv import load_dotenv import os # Load environment variables load_dotenv() # Configure FFmpeg for macOS/Linux os.environ["PATH"] += os.pathsep + '/usr/local/bin/' def main(): question = "Tell me about your experience with Python." synthesize_speech(question, "audio_samples/question.mp3") question_audio = AudioSegment.from_mp3("audio_samples/question.mp3") play(question_audio) candidate_response = recognize_speech("audio_samples/candidate-response.mp3") ollama_response = ask_question(candidate_response) print(f"Ollama Response: {ollama_response}") synthesize_speech(ollama_response, "audio_samples/response.mp3") response_audio = AudioSegment.from_mp3("audio_samples/response.mp3") play(response_audio) if __name__ == "__main__": main() ``` `ollama_api.py` Handles interaction with Ollama API: ``` import requests from src.config import OLLAMA_API_URL, OLLAMA_MODEL def ask_question(question): response = requests.post( OLLAMA_API_URL, json={"model": OLLAMA_MODEL, "input": question} ) response_data = response.json() return response_data["output"] ``` Converts audio to text using Google Cloud: ``` from google.cloud import speech import io def recognize_speech(audio_file): client = speech.SpeechClient() with io.open(audio_file, "rb") as audio: content = audio.read() audio = speech.RecognitionAudio(content=content) config = speech.RecognitionConfig( encoding=speech.RecognitionConfig.AudioEncoding.MP3, sample_rate_hertz=16000, language_code="en-US", ) response = client.recognize(config=config, audio=audio) for result in response.results: return result.alternatives[0].transcript ``` `text_to_speech.py` Converts text to audio using Google Cloud: ``` from google.cloud import texttospeech import os def synthesize_speech(text, output_file): # Verify that the environment variable is set assert 'GOOGLE_APPLICATION_CREDENTIALS' in os.environ, "GOOGLE_APPLICATION_CREDENTIALS not set" client = texttospeech.TextToSpeechClient() synthesis_input = texttospeech.SynthesisInput(text=text) voice = texttospeech.VoiceSelectionParams( language_code="en-US", ssml_gender=texttospeech.SsmlVoiceGender.NEUTRAL ) audio_config = texttospeech.AudioConfig( audio_encoding=texttospeech.AudioEncoding.MP3 ) response = client.synthesize_speech( input=synthesis_input, voice=voice, audio_config=audio_config ) with open(output_file, "wb") as out: out.write(response.audio_content) print(f"Audio content written to file {output_file}") ``` **🎉 Conclusion** By integrating Ollama and Google Cloud’s audio capabilities, you can create a virtual IT interviewer that enhances the recruitment process by automating initial candidate interactions.

https://dev.to/jay818/mastering-unit-testing-a-comprehensive-guide-ing

testing, vitest, cicd, typescript

## What In `Unit test` we test the functions, endpoints, components individually. In this we just test the functionality of the code that we have written and mock out all the external services [ DB Call, Redis] etc. ### How We are going to use `[Vitest](https://vitest.dev/)` for doing the testing as it has more smooth Typescript support rather than `Jest`. You can use any of them the code will look the same for both. **Some Testing Jargons** - **`Test suite`** - It is a collection of the test cases of a particular module. we use **`describe function`**, it helps to orgainse our test cases into groups. ```ts describe("Testing Sum Module", () => { // Multiple test cases for testing sum module }); describe("Testing Multiplication Module", () => { // Multiple test cases for testing Multiplication module }); ``` - **`Test case`** - It is a individual unit of testing, defined using `it` or `test`. ```ts describe("Testing Sum Module", () => { // Multiple test cases for testing sum module it("should give 1,2 sum to be 3", () => { // It checks that result matches or not expect(add(1, 2))toBe(3); }); }); ``` - **`Mocking`** - It is used to mock out various external calls like DB calls. To do this we use `vi.fn()`. It creates a mock functions and returns `undefined`. ```ts // db contains the code that we have to mock. // it is good practice to keep the content that we have to mock in a seprate file // vi.mock() is hoisted on the top of the test file. vi.mock("../db", () => { return { // prismaClient is imported from db file // we want to mock the prismaClient.sum.create() function prismaClient:{ sum:{ create:vi.fn(); } } }; }); ``` - **`Spy`** - It is basically used to spy on a function call, means as we are mocking the db call but we don't know that right arguments are passed to that db call or not, so to check that we use `spy`. ```ts // create is the method // prismaClient.sum is the object vi.spyOn(prismaClient.sum, "create"); // Now to check write arguments are passed on to the create method or not we can do this expect(prismaClient.sum.create).toHaveBeenCalledWith({ data: { a: 1, b: 2, result: 3, }, }); ``` -**`Mocking Return Values`** - Sometimes you want to use values returned by an async operation/external calls. Right now we can't use any of the values as we are mocking that call. To do so we have to use `mockResolvedValue`. ```ts //this is not the actual prismaClient object. This is the Mocked version of prismaClient that we are using that's why we are able to use mockResolvedValue. prismaClient.sum.create.mockResolvedValue({ id: 1, a: 1, b: 1, result: 3, }); ``` #### Examples **Unit test of an Express APP** In an express we write the app.listen in seprate file, cuz when we try to run the test everytime it will start a server & we can't hard code any PORT [ what if PORT is in use ]. So we use superset which automatically creates an use and throw server. we create an seperate bin.ts or main.ts file which will do the app.listen. - Run these Commands ```ts npm init -y npx tsc --init npm install express @types/express zod npm i -D vitest // supertest allow us to make server npm i supertest @types/supertest // used for deep-mocking, by using this we don't have to tell which method to mock, we can mock whole prisma client npm i -D vitest-mock-extended ``` Change rootDir and srcDir ```ts "rootDir": "./src", "outDir": "./dist", ``` Add a script to test in package.json ```ts "test": "vitest" ``` Adding an DB ```ts npm i prisma npx prisma init ``` Add this basic schema in `schema.prisma` ```ts model Sum { id Int @id @default(autoincrement()) a Int b Int result Int } ``` Generate the client (notice we don’t need to migrate since we wont actually need a DB) ```ts npx prisma generate ``` Create src/db.ts which exports the prisma client. This is needed because we will be mocking this file out eventually ```ts import { PrismaClient } from "@prisma/client"; export const prismaClient = new PrismaClient(); ``` src/Index.ts ```ts import express from "express"; import { z } from "zod"; import { prismaClient } from "./db"; export const app = express(); app.use(express.json()); const sumInput = z.object({ a: z.number(), b: z.number(), }); app.post("/sum", async (req, res) => { const parsedResponse = sumInput.safeParse(req.body); if (!parsedResponse.success) { return res.status(411).json({ message: "Invalid Input" }); } // const a = req.body.a; // const b = req.body.b; const answer = parsedResponse.data.a + parsedResponse.data.b; // we want to mock this as empty function const response = await prismaClient.sum.create({ // kya gurantee hai ki yeh data aise hi hoga , agar koi contributer isme change kar de to // to solve this issue we have spy that // abhi agar hum isme wrong input bhi pass karege tab bhi ye koi error nhi dega // so we have to use spies data: { a: parsedResponse.data.a, b: parsedResponse.data.b, result: answer, }, }); console.log(response.Id); // agar user try karega to return something else it will give them a error. // res.json({ answer, id: response.b }); res.json({ answer, id: response.Id }); }); // isme sab kuch headers mai pass hoga app.get("/sum", (req, res) => { const parsedResponse = sumInput.safeParse({ a: Number(req.headers["a"]), b: Number(req.headers["b"]), }); if (!parsedResponse.success) { return res.status(411).json({ message: "Invalid Input" }); } const answer = parsedResponse.data.a + parsedResponse.data.b; res.json({ answer }); }); ``` Create `__mocks__/db.ts` in the src folder, same folder in which `db.ts` resides. Its a type of convention, vitest looks for any `__mocks__` file to know what to mock. ```ts import { PrismaClient } from "@prisma/client"; import { mockDeep } from "vitest-mock-extended"; export const prismaClient = mockDeep<PrismaClient>(); ``` **`index.test.ts`** ```ts import { describe, it, expect, vi } from "vitest"; import request from "supertest"; import { app } from "../index"; import { prismaClient } from "../__mocks__/db"; // vi.mock("../db", () => ({ // prismaClient: { sum: { create: vi.fn() } }, // })); vi.mock("../db"); // // Mocking the return value using mockResolvedValue // prismaClient.sum.create.mockResolvedValue({ // Id: 1, // a: 1, // b: 2, // result: 3, // }); describe("POST /sum", () => { it("Should return the sum of 2,3 to be 6", async () => { // Mocking the return value using mockResolvedValue prismaClient.sum.create.mockResolvedValue({ Id: 1, a: 1, b: 2, result: 3, }); vi.spyOn(prismaClient.sum, "create"); const res = await request(app).post("/sum").send({ a: 1, b: 2, }); expect(prismaClient.sum.create).toBeCalledWith({ data: { a: 1, b: 2, result: 3, }, }); expect(prismaClient.sum.create).toBeCalledTimes(1); expect(res.status).toBe(200); expect(res.body.answer).toBe(3); expect(res.body.id).toBe(1); }); it("Should return sum of 2 negative numbers", async () => { // Mocking the return value using mockResolvedValue prismaClient.sum.create.mockResolvedValue({ Id: 1, a: 1, b: 2, result: 3, }); vi.spyOn(prismaClient.sum, "create"); const res = await request(app).post("/sum").send({ a: -10, b: -20, }); expect(prismaClient.sum.create).toBeCalledWith({ data: { a: -10, b: -20, result: -30, }, }); expect(prismaClient.sum.create).toBeCalledTimes(1); expect(res.status).toBe(200); expect(res.body.answer).toBe(-30); expect(res.body.id).toBe(1); }); it("If wrong input is provided, it should return 411 with a msg", async () => { const res = await request(app).post("/sum").send({ a: "abcd", b: 2, }); expect(res.status).toBe(411); expect(res.body.message).toBe("Invalid Input"); }); }); describe("GET /sum", () => { it("should return the sum of 2,3 to be 5", async () => { const res = await request(app) .get("/sum") .set({ a: "2", b: "3", }) .send(); expect(res.status).toBe(200); expect(res.body.answer).toBe(5); }); }); ``` Now Run `npm run test` to test your code. ### Implementing CI Pipeline Create an `.github/workflows/test.yml` file This below code will automatically tests the if any code is pushed on main branch or for any pull request. ```yml name: Testing on CI on: pull_request: branches: - main push: branches: - main jobs: test: runs-on: ubuntu-latest steps: - name: Checkout code uses: actions/checkout@v2 - name: Set up Node.js uses: actions/setup-node@v2 with: node-version: 20 - name: Install dependencies run: npm install && npx prisma generate - name: Run tests run: npm test ```

Creating a React component using Symfony UX

Introduction I have been using Angular to build my front-ends for much time and I wanted...

https://dev.to/icolomina/creating-a-react-component-using-symfony-ux-1bk9

react, symfony, ux, php

## Introduction I have been using Angular to build my front-ends for much time and I wanted to try another framework. I usually read a lot of posts and articles about [React](https://es.react.dev/) and I decided to start learning it. As I am a [Symfony](https://symfony.com/) lover, I decided to start my learning trying to integrate a React component by using the [symfony/ux-react](https://symfony.com/bundles/ux-react/current/index.html) component. In this post, I will explain the steps I've followed to achieve it. ## Install Webpack Encore [Webpack](https://webpack.js.org/) is a bundler for JavaScript applications. It takes in multiple entry points and bundles them into optimized output files, along with their dependencies, for efficient delivery to the browser. Symfony provides a component to easily integrate webpack within your application. You can install it using composer and then npm to install the javascript required libraries: ```shell composer require symfony/webpack-encore-bundle npm install ``` > This post assumes you are using [symfony-flex](https://symfony.com/doc/current/quick_tour/flex_recipes.html) After [installing webpack-encore-bundle](https://symfony.com/doc/current/frontend/encore/installation.html) you will see an **assets** directory under your project-root folder containing the following files: - **app.js**: It is the file which will manage all your frontend dependencies. In this post case, react components. It will also import css files. - **styles/app.css**: A file where you can put your CSS. You can use another css files. To be able to use them in your project, you should import them in the **app.js** file. The **app.js** file contains the following content after created: ```javascript import './styles/app.css'; ``` Encore flex recipe also creates a file on your project-root folder named **webpack.config.js**. This file contains all the webpack configuration to bundle your assets. At this point, the most important configurations are the following: - **The Output Path**: Specifies the directory where compiled assets will be stored. - **The Public Path**: Specifies the public path used by the web server to access the output path. - **Entry**: Specifies the main entry file (app.js). When the flex recipe creates the **webpack.config.js** file, it sets the previous values as follows: ```javascript Encore .setOutputPath('public/build/') .setPublicPath('/build') .addEntry('app', './assets/app.js') ; ``` Unless we need some special configuration, we can leave these values ​​as they are. ## Installing The Stimulus Bundle The [stimulus-bundle](https://symfony.com/bundles/StimulusBundle/current/index.html) is the component in charge of activating the other symfony ux-components you want to use in your application (in our case, symfony/ux-react). The stimulus-bundle must be installed using composer: ```shell composer require symfony/stimulus-bundle npm install ``` As the installation uses Symfony Flex, after it, we will see two new files under the **assets** directory: - **bootstrap.js**: This file starts the stimulus app so that other symfony ux-components can be installed. ```javascript import { startStimulusApp } from '@symfony/stimulus-bridge'; const app = startStimulusApp(); ``` The above code snippet shows the **bootstrap.js** file contents. It simply starts the stimulus app. We must import this file in the **app.js** file: ```javascript import './bootstrap.js'; import './styles/app.css'; ``` - **controllers.json**: Contains the ux-components which must be activated within the application. ```json { "controllers": [], "entrypoints": [] } ``` The above **controllers.json** is empty because we have not installed the ux-react component yet. After installing it, we will come back to this file to analyze its content. This recipe also adds the following line in the **webpack.config.js** file: ```javascript Encore // ........ .enableStimulusBridge('./assets/controllers.json') // ........ ; ``` This line enables the stimulus bridge specifying that the **controllers.json** file will contain all the ux-components to activate. ## Enabling Typescript To enable typescript, we must follow the next steps: ### Enable typescript in webpack.config.js You will find the following commented line in the **webpack.config.js** file: ```javascript Encore // .......... //.enableTypeScriptLoader() // .......... ; ``` We have to uncomment the above line. ### Rename app.js to app.ts As we are going to use typescript, we must rename the app.js to use the typescript extension. Then, we have to return to the **webpack.config.js** file and change this line: ```javascript .addEntry('app', './assets/app.js') ``` By this: ```javascript .addEntry('app', './assets/app.ts') ``` ### Create the tsconfig.json file The **tsconfig.json** file is a configuration file used by the TypeScript compiler to determine how to compile TypeScript code into JavaScript. It contains various settings and options that control the behavior of the TypeScript compiler, such as the target JavaScript version, module resolution, and source maps. Let's see how this file looks like: ```json { "compileOnSave": true, "compilerOptions": { "sourceMap": true, "moduleResolution": "node", "lib": ["dom", "es2015", "es2016"], "jsx": "react-jsx", "target": "es6", }, "include": ["assets/**/*"] } ``` > If you want to know more about the tsconfig configuration parameters, you can read the [docs](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html). The two important parameters we have to pay attention to are the following: - **jsx**: Specifies the JSX factory function to use - **include**: Specifies that all the ts files under the assets folder will be compiled. ## Installing the UX-react component Having encore and stimulus-bundle installed and typescript enabled, we are ready to install the symfony ux-react component. As always, we must use composer to install it: ```shell composer require symfony/ux-react npm install -D @babel/preset-react --force ``` As this component also uses Symfony Flex, after being installed it will add the following line in the **webpack.config.js**. ```javascript Encore // ....... .enableReactPreset() // ....... ; ``` The above line enables react in the webpack config. This recipe also adds the following code to your app.ts file: ```typescript import './bootstrap.js'; import { registerReactControllerComponents } from '@symfony/ux-react'; registerReactControllerComponents(require.context('./react/controllers', true, /\.(j|t)sx?$/)); import './styles/app.css'; ``` The two lines after the **bootstrap.js** import enable the automatic registration for all react components located into the **assets/react/controllers** folder. It supports both jsx and tsx (typescript) extensions. If we look now in the controllers.json file, we will see the following content: ```json { "controllers": { "@symfony/ux-react": { "react": { "enabled": true, "fetch": "eager" } } }, "entrypoints": [] } ``` As you can see, the controllers key has a new entry. This entry enables react components and specifies an eager fetch. An eager fetch means that all the React components will be fetched upfront. If you would set the "lazy" value, the react components would be loaded only when they are required. For this article, an eager fetch can fit. ## Creating the React Component Now it's time to create the React component. We are going to create a react component which will contains a form with an input named "amount" and a button to call a function which makes an api call. ### Creating the Api Service Before showing the component's code, let's create a class which will contain the method to send the request call. This file must be located under the **assets/react/services** folder and must have the **.ts** extension. ```typescript export class ApiService { sendDeposit(amount: number): Promise<any> { return fetch('/<your_call_url>', { method: "POST", mode: "same-origin", headers: { "Content-Type": "application/json", }, body: JSON.stringify({ 'amount' : amount }) }); } } ``` The **ApiService** class uses the global function **fetch** from the [Javascript API Fetch](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) to send the request to the server. ### Creating the component This component must be located under the **assets/react/controllers** folder and have a **tsx** extension. ```typescript import { useState, useEffect } from 'react'; import { ApiService } from '../services/api'; interface FormData { amount: number; } export default function DepositForm () { const [formData, setFormData] = useState<FormData>({ amount: 0 }); const [depositSuccess, setDepositSuccess] = useState<boolean>(false); const apiService: ApiService = new ApiService(); useEffect(() => { if (depositSuccess) { console.log('Form submitted successfully!'); } }, [depositSuccess]); const handleChange = (event: any) => { const { name, value } = event.target; setFormData ( (previousFormData) => ({ ...previousFormData, [name]: value}) ) } const handleForm = (event: any) => { apiService.sendDeposit(formData.amount).then( (r: any) => { if (!r.ok) { throw new Error(`HTTP error! Status: ${r.status}`); } setDepositSuccess(true); } ) } return ( <div> <div className="row mb-3"> <div className="col-md-12"> <div className="form-floating mb-3 mb-md-0"> <input type="text" name="amount" id="amount" className="form-control" value={formData.amount} onChange={handleChange} /> <label htmlFor="amount" className="form-label">Amount</label> </div> </div> </div> <div className="row mb-3"> <div className="col-md-12"> <button type="button" className="btn btn-primary" onClick={handleForm}>Send deposit</button> </div> </div> </div> ); } ``` Let's analyze the component step-by-step: ```typescript import { useState, useEffect } from 'react'; import { ApiService } from '../services/api'; interface FormData { amount: number; } ``` - It imports the React [useState](https://react.dev/reference/react/useState) and [useEffect](https://react.dev/reference/react/useEffect) hooks - It imports the previously created **ApiService** class - It creates an interface to represent the form fields. ```typescript const [formData, setFormData] = useState<FormData>({ amount: 0 }); const [depositSuccess, setDepositSuccess] = useState<boolean>(false); const apiService: ApiService = new ApiService(); useEffect(() => { if (depositSuccess) { console.log('Form submitted successfully!'); } }, [depositSuccess]); ``` - It uses the useState hook to initialize the formData amount value and the depositSuccess value. - It creates an ApiService instance. - It uses the useEffect hook to show a console message when depositSuccess becomes true. ```typescript const handleChange = (event: any) => { const { name, value } = event.target; setFormData ( (previousFormData) => ({ ...previousFormData, [name]: value}) ) } const handleForm = (event: any) => { apiService.sendDeposit(formData.amount).then( (r: any) => { if (!r.ok) { throw new Error(`HTTP error! Status: ${r.status}`); } setDepositSuccess(true); } ) } ``` - The **handleChange** function is used to update formData when the form amount value changes. - The **handleForm** function sends the request using the **ApiService** sendDeposit function. ```typescript return ( <div> <div className="row mb-3"> <div className="col-md-12"> <div className="form-floating mb-3 mb-md-0"> <input type="text" name="amount" id="amount" className="form-control" value={formData.amount} onChange={handleChange} /> <label htmlFor="amount" className="form-label">Amount</label> </div> </div> </div> <div className="row mb-3"> <div className="col-md-12"> <button type="button" className="btn btn-primary" onClick={handleForm}>Send deposit</button> </div> </div> </div> ); ``` The component html contains an input and a button. The input value property holds the **formData.amount** value and the **onChange** event executes the **handleChange** function. As the **handleChange** function updates the form data with the new values, the amount field will be updated after every change. The button executes the **handleForm** function after being clicked. ## Calling the React component into Twig Calling the React component into Twig is as easy as use the twig **react_component** function. ```twig {% extends 'base.html.twig' %} {% block title %}Make a deposit{% endblock %} {% block body %} <div class="container-fluid px-4"> <h1 class="mt-4">Deposits</h1> <ol class="breadcrumb mb-4"> <li class="breadcrumb-item active">Send deposit and start generating interests</li> </ol> <div class="row" > <div class="col-xl-6"> <div class="card mb-4"> <div class="card-header"> <i class="fas fa-chart-area me-1"></i> Send deposit form </div> <div class="card-body"> <div {{ react_component('DepositForm')}} </div> </div> </div> </div> </div> </div> {% endblock %} ``` **Important**: You have to include your webpack bundled assets in your base.html.twig file (or the corresponding file in your project) so that the stimulus application is initialized and the react components are loaded. This can be done within the html head tag. ```twig <head> <meta charset="utf-8" /> <meta http-equiv="X-UA-Compatible" content="IE=edge" /> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no" /> <meta name="description" content="" /> <meta name="author" content="" /> <title>{% block title %}Welcome!{% endblock %}</title> {% block stylesheets %} <!-- Your other stylesheets (if there are) --> {{ encore_entry_link_tags('app') }} {% endblock %} {% block javascripts %} <!-- Your other javascripts (if there are) --> {{ encore_entry_script_tags('app') }} {% endblock %} </head> ``` The **encore_entry_link_tags** and the **encore_entry_script_tags** functions include both the bundled css and scripts. ## Conclusion This article shows how to prepare your symfony project to support react and how to create a react component and use it within your project using the **react_component** TWIG function. Although backend and frontend applications are usually separated and communicate via APIs, this approach can be useful in situations when frontend and backend can co-live in the same project. > If you enjoy my content and like the Symfony framework, consider reading my book: [Building an Operation-Oriented Api using PHP and the Symfony Framework: A step-by-step guide](https://amzn.eu/d/3eO1DDi)

https://dev.to/babichweb/mythbusting-dom-is-dom-the-same-as-html-561f

One of the misconceptions circulating among the young generation of web developers, and not only them, is the belief that the DOM is actually the same HTML, just in the browser. This misconception is further fueled by the fact that the browser's DOM inspector displays everything within the webpage as the good old hypertext markup, adding more confusion to the understanding of these things. So, as I loudly declare today: "DOM is not HTML.", the question arises, "What is it, then?" Let's try to figure it out together. First, let's look at the dry academic definition. DOM (Document Object Model) is a programming interface that allows programs to dynamically access and update a document's content, structure, and styles. The DOM represents the document as a data structure, such as a tree, where each node is an object representing a part of the document, such as an element, attribute, or text content. Does this make a bit more sense? If you answered "yes," then I have every reason to suspect you have a bit of a pedant in you who loved "Legends and Myths of Ancient Greece" as a favourite book in kindergarten. Wait, that's about me... Oh, never mind, let's try to explain it more simply. Let's imagine that HTML tags are images of LEGO blocks, and HTML attributes in this example are different characteristics of these images: colour, orientation in space, etc. Then our HTML documents are those instruction booklets from which you can assemble what's illustrated, like the Millennium Falcon, and then, if desired and inspired, a deep-sea pterodactyl with a pedal drive and a nuclear warhead in its butt. And the DOM is what you've assembled from the real blocks, which you can touch with your hands. As in a construction set, each part, a DOM node, is a piece of a complex hierarchy, simultaneously having conventionally parental and child structures. You can imagine this hierarchy in various ways, so for simplification, let's imagine that our LEGO is at least four-dimensional and can simultaneously have both flat and spatial relationships. Just as you can find the necessary part in the already assembled constructor (well, when you were assembling and realized three packets ago that you missed inserting the green block), you can also find the required element in the DOM. Moreover, you can find many different elements simultaneously based on various attributes, usually id, tag name, class, attribute value, and others. Moreover, you can not only find these elements but also perform various useful actions with them! For instance, you can replace some blocks with others, add new ones, remove unnecessary ones, and even change the properties of these blocks. In a real constructor, this wouldn't work, but if it did, then you could. After all, we have an imaginary, four-dimensional LEGO, so let it be. And just like a real LEGO constructor, the DOM can be genuinely interactive, i.e., it can respond to user actions. Just like in those expensive sets where you can assemble a working Lamborghini model at a 1:24 scale, with a beeping horn, a buzzing engine, opening-closing doors, and imaginary cocaine spilt on the passenger seat. I'm talking about DOM events here, not cocaine, but the fact that the DOM can handle events. For example, you press a hypothetical door, and it opens. So it is in the DOM — you press a button, an event is triggered, and you can subscribe to it, opening hypothetical doors. There are many events in the DOM, and all of them are very interesting, and now you can even create your custom events, not limited to standard ones. So what am I saying? The DOM is not HTML but a completely separate thing that has a whole range of properties unique to it, and thanks to them, we can create attractive, interesting, and diverse web applications.

https://dev.to/wassim31/real-time-disk-size-expanding-in-a-virtual-machine-on-linux-machine-307i

I was compiling the Linux kernel from source and i had a vm running AlmaLinux with 20GB Logical volume, so i attained the maximum size, i had to expend my disk size without losing my data, the progress of a 12 hours compilation process(yes heavy kernel, and a weak hardware) this solution is used in storage management in cloud services providers AWS, Azure .. **_Linux Distribution_** : AlmaLinux 9.4 on Vmware Workstation 7 When you expand the disk size of your Linux virtual machine (VM) on VMware, you must adjust the partitions within the system to utilize the additional space. This guide will walk you through the steps required to resize the partitions and filesystems using bash. **Prerequisites** Before you begin, ensure you have: Expanded the disk size of your VM in VMware. Root or sudo access to your Linux VM. **Step 1:** Identify the New Disk Size First, verify the current disk and partition sizes using the lsblk command: ``` lsblk ``` The output will show all block devices and their partitions. Identify the disk you have expanded. For example: ``` NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS sr0 11:0 1 988M 0 rom nvme0n1 259:0 0 100G 0 disk ├─nvme0n1p1 259:1 0 1G 0 part /boot └─nvme0n1p2 259:2 0 19G 0 part ├─almalinux-root 253:0 0 17G 0 lvm / └─almalinux-swap 253:1 0 2G 0 lvm [SWAP] ``` **Step 2:** Resize the Partition Use the **growpart** utility to resize the partition. If it's not already installed, you can install it with: ``` sudo dnf install cloud-utils-growpart ``` Then, resize the partition nvme0n1p2: ``` sudo growpart /dev/nvme0n1 2 ``` **Step 3:** Resize the Physical Volume (PV) Next, resize the physical volume to recognize the expanded partition: ``` sudo pvresize /dev/nvme0n1p2 ``` **Step 4:** Verify the Physical Volume Size Verify the changes using the pvs command: ``` sudo pvs ``` **Step 5:** Resize the Logical Volume (LV) Assuming you want to allocate all the new space to the root logical volume (almalinux-root): ``` sudo lvextend -l +100%FREE /dev/almalinux/root ``` **Step 6:** Determine the Filesystem Type Before resizing the filesystem, determine the filesystem type. You can do this with the **df -Th** or **lsblk -f** commands: ``` df -Th ``` or ``` lsblk -f ``` **Step 7:** Resize the Filesystem Depending on the filesystem type, use the appropriate command to resize the filesystem. **For ext4:** ``` sudo resize2fs /dev/almalinux/root ``` **For xfs:** ``` sudo xfs_growfs / ``` **Step 8:** Verify the Changes Finally, verify that the new space is available using the lsblk and df -h commands: ``` lsblk df -h ``` **Conclusion** By following these steps, you can effectively utilize the additional disk space after expanding your Linux VM disk on VMware.

angular, xstate, webdev

--- canonical_url: https://www.wordman.dev/blog/xstate-ngx-announcement/ --- I am very excited to announce the alpha release of **xstate-ngx**! This marks a significant milestone in integrating XState with Angular, and I can't wait for you to try it out and share your feedback. For now, the project is published under `xstate-ngx`. However, we're planning to move it into the official XState monorepo once discussions are finalized and your feedback has been implemented. You can track the progress and discussions in the [related PR](https://github.com/statelyai/xstate/pull/4816/files). ## What is xstate-ngx You might be wondering, what is xstate-ngx?! The official xstate documentation says the following: > XState is a state management and orchestration solution for JavaScript and TypeScript apps. > It uses event-driven programming, state machines, statecharts, and the actor model to handle complex logic in predictable, robust, and visual ways. XState provides a powerful and flexible way to manage application and workflow state by allowing developers to model logic as actors and state machines. It integrates well with React, Vue, Svelte, and [...] and now there is an angular integration! xstate-ngx uses the primitives that XState provides and provides a thin wrapper to utilize Angular's Dependency Injection mechanism and signals. ## Why Alpha? This alpha release aims to give you a taste of the developer experience with `xstate-ngx`. I want you to play with it, explore its capabilities, and most importantly, provide feedback on the general API design. Your input is crucial in shaping the future of this integration. ## Getting Started To help you get started, we've provided several examples on [GitHub](https://github.com/niklas-wortmann/xstate-angular). Here's a quick highlight of how you can use `xstate-ngx` in your projects: ### Example: Simple Toggle Machine ```typescript import { createMachine, interpret } from 'xstate'; import { useMachine } from 'xstate-ngx'; import { Component, inject } from '@angular/core'; // Define your machine const toggleMachine = createMachine({ id: 'toggle', initial: 'inactive', states: { inactive: { on: { TOGGLE: 'active' }, }, active: { on: { TOGGLE: 'inactive' }, }, }, }); const ToggleMachineService = useMachine(toggleMachine); @Component({ selector: 'app-toggle', providers: [ToggleMachineService], template: ` <button (click)="toggleMachine.send('TOGGLE')"> {{ toggleMachine.snapshot().value === 'inactive' ? 'Off' : 'On' }} </button> `, standalone: true }) export class ToggleComponent { protected toggleMachine = inject(ToggleMachineService) } ``` In this example, we define a simple toggle state machine and create an Injectable using `useMachine` from `xstate-ngx`. The returned Service can then be used in a component. The `snapshot` property is a signal allowing for fine-grained reactivity, but also enabling to easily derive state by using the `compute` function. ## Special Thanks I couldn't have reached this milestone without the invaluable contributions and support from the community: - [**Enea Jahollari**](https://x.com/Enea_Jahollari) and [**Chau Tran**](https://x.com/Nartc1410) for their first round of feedback. - [**David Khourshid**](https://x.com/DavidKPiano) and [**Mateusz Burzyński**](https://x.com/AndaristRake) for their outstanding work on XState, their interest in an Angular implementation, and their insightful discussions about this topic. - The design and implementation are heavily inspired by NgRx Signals, so many thanks to the NgRx team! ## Join the Conversation Your feedback is essential to us. Join the conversation, try out the alpha release, and let us know your thoughts. For now the best place to share any kind of feedback is the [xstate-angular repository](https://github.com/niklas-wortmann/xstate-angular). Together, we can make `xstate-ngx` a robust and delightful tool for the Angular community. Let me know what you think and happy coding!

Lado Okhotnikov and his revolutionary move to develop virtual realms. How Motion Capture technology is introduced in the Meta Force Metaverse The recently published [article on the mo-cap technology](https://beincrypto.com/lado-okhotnikov-about-an-integral-part-of-the-project/) reveals an interesting case of its introduction to metaverses. Lado Okhotnikov, the visionary behind Meta Force, asserts innovative technologies are just necessary to create something intriguing and innovative in the digital realms. In particular, his platform tried to take advantage of the mocap technology. It has become indispensable in the realm of expensive projects worth millions of dollars. It is really preferable to resort to it when a large budget is involved. The article shows how it works. Why integrate Motion Capture This innovative technology is used, for instance, in blockbuster games such as Halo 4, LA Noire, and Beyond: Two Souls and lots of other hits. The technology enables actors to infuse their digital counterparts with lifelike movements, transcending traditional voice acting to embody characters authentically on-screen. A new standard in Metaverse experiences Meta Force also utilizes the technology pursuing unparalleled realism. According to the Metaworld'd concept, its inhabitants should seamlessly mirror reality. It is important to achieve it for complete immersion of users, without any artificial undertones. Lado Okhotnikov envisions setting a new standard in Metaverse experiences. He was inspired by notable games and decided to borrow some techniques from games like [GTA V](https://www.rockstargames.com/gta-v ). What stands them apart are character animations, which are derived from real-life performances rather than computer simulations. Mo-cap in Meta Force: how it happens Lado says that understanding the mo-cap mechanics was just the beginning. The importance of spontaneity and improvisation became evident as the team explored virtual environments. It involved rigorous experimentation and even Lado personally participated in it. He wanted to ensure that his digital avatar reflects true-to-life movements. Achieving realism in tasks like this is a continuous process. In Meta Force the dedicated team of professionals, including mo-cap designers, works over it. The members of the team try to refine every detail. Their expertise enhances animations, ensuring that the final product is visually captivating and devoid of the artificiality found in conventional animation. The role of the mocap designer is instrumental. The attempt to breathe life into visuals adds new dynamism to the objects. There are numerous challenges on the way as users delve deeper into the animation. Meta Force by Lado Okhotnikov represents more than just a virtual platform since it embodies a paradigm shift in the development of virtual worlds. The team’s vision is to blur the frontiers between the real and virtual worlds. The platform is introducing a new and original way of evolving virtual environments on a worldwide scale.

webdev, hng, linux, devops

As a SysOps engineer, managing users and groups in a Linux environment can be a repetitive and time-consuming task. To streamline this process, we can leverage a bash script to automate user creation, group assignments, home directory setup, password generation, and logging. This article walks through the implementation of such a script, create_users.sh, which reads user information from a text file and performs the necessary operations. This solution is especially useful when onboarding new employees. Script Requirements and Functionality Our script will: Read a text file containing usernames and groups. Create users with personal groups matching their usernames. Assign users to additional specified groups. Set up home directories with appropriate permissions. Generate random passwords for new users. Log all actions to /var/log/user_management.log. Store generated passwords securely in /var/secure/user_passwords.csv. Implementation Details 1. Script Initialization and Input Validation The script starts by defining log and password files. It then checks if the input file is provided and exists: bash Copy code LOG_FILE="/var/log/user_management.log" PASSWORD_FILE="/var/secure/user_passwords.csv" if [ $# -eq 0 ]; then echo "Usage: $0 <name-of-text-file>" exit 1 fi if [ ! -f $1 ]; then echo "Error: File $1 not found!" exit 1 fi 2. Secure Directory and File Setup We ensure that the directory for storing passwords exists and has the correct permissions: bash Copy code mkdir -p /var/secure touch $PASSWORD_FILE chmod 600 $PASSWORD_FILE 3. Reading and Processing the Input File The script reads the input file line by line, creating users and assigning them to groups as specified: bash Copy code while IFS=';' read -r username groups; do username=$(echo "$username" | xargs) groups=$(echo "$groups" | xargs) if id -u "$username" >/dev/null 2>&1; then log_message "User $username already exists" else useradd -m -g "$username" -s /bin/bash "$username" log_message "User $username created with primary group $username" chmod 700 /home/$username chown $username:$username /home/$username password=$(openssl rand -base64 12) echo "$username:$password" | chpasswd echo "$username,$password" >> $PASSWORD_FILE log_message "Password for user $username set and stored securely" fi IFS=',' read -ra additional_groups <<< "$groups" for group in "${additional_groups[@]}"; do group=$(echo "$group" | xargs) if [ $(getent group "$group") ]; then usermod -aG "$group" "$username" log_message "User $username added to group $group" else groupadd "$group" usermod -aG "$group" "$username" log_message "Group $group created and user $username added" fi done done < "$1" Logging and Security All actions are logged for auditing purposes. Passwords are stored securely with restricted access to ensure only the file owner can read them. **Conclusion** Automating user and group management in Linux environments can significantly reduce administrative overhead. The create_users.sh script provides a robust solution for onboarding new users, ensuring that they are set up with the necessary permissions and groups efficiently.

https://dev.to/emanuelgustafzon/what-is-a-di-container-468h

programming, dependencyinversion, designpatterns

In the last post in this series we learned about dependency injection. We saw that we needed to manually create an instance of the database connection class before creating an instance of the post routes class. Then, we passed the connection instance into the constructor of the posts object. Imagine, though, if we could just create an instance of the post routes class, and the system itself would automatically know that the posts class depends on a database connection and create that instance for us 💡. There you have it! A Dependency Injection Container is doing just that. A DI Container is responsible for creating instances of classes and managing their dependencies. Here’s a more detailed breakdown: ## Registering Services First, you register your classes with the container and specify their dependencies. For example, you tell the container that PostRoutes depends on a DatabaseConnection. ## Resolving Services When you ask the container to resolve a service (i.e., create an instance of a class), the container: 1. Creates an instance of the class. 2. Resolves all the dependencies that the class needs by creating instances of those dependencies as well. This means that the container automatically creates and injects instances of all the required dependencies, simplifying the process of creating complex objects with multiple dependencies. # The lifetime of instances. You need to keep in mind how long an instance live before it gets renewed. We call this scope. The 3 most common scopes are `transient`, `singleton` and `request` or even called `scoped` in .NET. ## Singleton The singleton scope means that the DI Container creates one instance of the service and keeps that same instance throughout the program’s lifetime. Every time you resolve the service, you get the same instance. This is useful for services that maintain state or are expensive to create and should be shared across the entire application. #####Example: Logging Service A logging service that logs messages to the console can be a good use case for a singleton service. A logging service keeps the same state and stay consistent throughout the program. ## Transient Transient scope means that the DI Container creates a new instance of the service each time it is resolved. This is useful for lightweight, stateless services where each operation should be independent of others. #####Example: Unique ID Generation Service A service that generates unique IDs might be a good use case for a transient service. Each request to this service should produce a new, unique value without retaining any state from previous requests. ## Scoped or Request Scoped services last as long as the HttpContext lasts. This scope is particularly useful in web applications. When working in the backend, you receive HTTP requests from clients. Each request has a context, known as the HttpContext, which lasts from when the client sends the request to the backend until the backend sends a response back to the client. During this period, multiple operations might occur, such as connecting to a database, fetching data to authorize the user, retrieving various resources, etc. #####Example: Database Connection Service For a database connection service, you want the same instance to be used throughout the entire HttpContext to avoid losing the connection during the request processing. This ensures that the database connection remains consistent and efficient throughout the lifecycle of the request. #####Stay tuned because in the next chapter we will start building our own DI container in JavaScript.

The [HNG](https://hng.tech/internship) Internship has me on a thrilling ride! My first project is to create a Bash script to automate user management on a Linux server. This project showcases scripting's power and highlights the skills I'm gaining at [HNG](https://hng.tech/internship). Get ready to see how this script simplifies user and group management! **Prerequisites and Requirements** **Prerequisites:** Access to a Linux environment (e.g., Ubuntu) Basic understanding of how to run scripts and manage files in a Linux terminal Permissions to create users, groups, and files Requirements: Input File Format: The script will read a text file where each line is formatted as {username; groups}. Example: ``` kelvin; admin,dev Hannah; dev,tester Gift; admin,tester ``` **Script Actions:** Create users (kelvin, Hannah, Gift) and their personal groups (admin, dev, tester). Place users in the designated additional groups (admin, dev, tester). Create home directories for each user with the correct permissions. Create random passwords for each user. Record all actions in /var/log/user_management.log. Save passwords securely in /var/secure/user_passwords.txt. Gracefully manage errors, such as users or groups that already exist. **Step-by-Step Implementation** **Step 1:** Script Initialization and Setup Set up the initial environment for the script, including defining file locations and creating necessary directories. Define File Locations: Initializes paths for logging and password storage. Create Directories: Ensures necessary directories exist. Set File Permissions: Create and set permissions for the log and password files. ``` #!/bin/bash # Define log and password file locations LOG_FILE="/var/log/user_management.log" PASSWORD_FILE="/var/secure/user_passwords.txt" # Create Directories mkdir -p /var/log mkdir -p /var/secure # Create and set permissions for the log file touch $LOG_FILE chmod 644 $LOG_FILE # Create and set permissions for the password file touch $PASSWORD_FILE chmod 600 $PASSWORD_FILE ``` **Step 2:** **Logging Function Creation** Create a function to log actions performed by the script with timestamps. ``` # Function to log messages with timestamps log_action() { echo "$(date '+%Y-%m-%d %H:%M:%S') : $1" >> $LOG_FILE } ``` **Step 3:** **Argument Checking** Verify that the script is provided with the correct number of arguments. ``` # Check if a correct number of arguments is provided. if [ $# -ne 1 ]; then log_action "Usage: $0 <user-list-file>. Exiting." exit 1 fi USER_LIST_FILE=$1 # Check if user list file exists if [ ! -f $USER_LIST_FILE ]; then log_action "File $USER_LIST_FILE does not exist! Exiting." exit 1 fi ``` **Step 4:** **Reading and Processing User List** Read each line from the user list file, extracting usernames and associated groups. ``` # Process each line in the user list file while IFS=';' read -r username groups; do username=$(echo $username | xargs) groups=$(echo $groups | xargs) # Further actions based on extracted data will be performed in subsequent steps. done < $USER_LIST_FILE ``` **Step 5:** **User Existence Checking and Creation** Verify if each user already exists; if not, create the user. ``` # Check if the user already exists if id -u $username >/dev/null 2>&1; then log_action "User $username already exists. Skipping." continue fi # Create the user if they do not exist useradd -m $username if [ $? -eq 0 ]; then log_action "User $username created successfully." else log_action "Failed to create user $username." continue fi ``` **Step 6:** **Group Handling** Create the necessary groups for each user and assign them appropriately. ``` # Assign user to specified additional groups IFS=',' read -ra USER_GROUPS <<< "$groups" for group in "${USER_GROUPS[@]}"; do group=$(echo $group | xargs) if ! getent group $group >/dev/null; then groupadd $group if [ $? -eq 0 ]; then log_action "Group $group created successfully." else log_action "Failed to create group $group." continue fi fi usermod -aG $group $username log_action "User $username added to group $group." done ``` **Step 7:** **Home Directory Setup** Ensure each user has a home directory set up with appropriate permissions. ``` # Set up home directory permissions chmod 755 /home/$username chown $username:$username /home/$username log_action "Home directory permissions set for user $username." ``` **Step 8:** **Password Generation and Storage** Generate a secure password for each user and store it securely. ``` # Generate and store passwords securely password=$(date +%s | sha256sum | base64 | head -c 12 ; echo) echo "$username,$password" >> $PASSWORD_FILE log_action "Password for user $username set successfully." ``` **Step 9:** **Script Completion and Finalization** Conclude the script execution, logging the completion of all actions. ``` # Final log entry log_action "Script execution completed." ``` Putting It All Together Here's the complete script: ``` #!/bin/bash # Step 1: Define File Locations LOG_FILE="/var/log/user_management.log" PASSWORD_FILE="/var/secure/user_passwords.txt" # Step 2: Create Directories mkdir -p /var/log mkdir -p /var/secure # Step 3: Set File Permissions touch $PASSWORD_FILE chmod 600 $PASSWORD_FILE touch $LOG_FILE chmod 644 $LOG_FILE # Step 4: Define Logging Function log_action() { echo "$(date '+%Y-%m-%d %H:%M:%S') : $1" >> $LOG_FILE } # Step 5: Argument Checking if [ $# -ne 1 ]; then log_action "Usage: $0 <user-list-file>. Exiting." exit 1 fi USER_LIST_FILE=$1 if [ ! -f $USER_LIST_FILE ]; then log_action "File $USER_LIST_FILE does not exist! Exiting." exit 1 fi # Step 6: Reading and Processing User List while IFS=';' read -r username groups; do username=$(echo $username | xargs) groups=$(echo $groups | xargs) # Step 7: User Existence Checking and Creation if id -u $username >/dev/null 2>&1; then log_action "User $username already exists. Skipping." continue fi useradd -m $username if [ $? -eq 0 ]; then log_action "User $username created successfully." else log_action "Failed to create user $username." continue fi # Step 8: Group Handling IFS=',' read -ra USER_GROUPS <<< "$groups" for group in "${USER_GROUPS[@]}"; do group=$(echo $group | xargs) if ! getent group $group >/dev/null; then groupadd $group if [ $? -eq 0 ]; then log_action "Group $group created successfully." else log_action "Failed to create group $group." continue fi fi usermod -aG $group $username log_action "User $username added to group $group." done # Step 9: Home Directory Setup chmod 755 /home/$username chown $username:$username /home/$username log_action "Home directory permissions set for user $username." # Step 10: Password Generation and Storage password=$(date +%s | sha256sum | base64 | head -c 12 ; echo) echo "$username,$password" >> $PASSWORD_FILE log_action "Password for user $username set successfully." done < $USER_LIST_FILE # Step 11: Script Completion and Finalization log_action "Script execution completed." ``` **Trying It Out** Save the file as create_user.sh. Upload it to a GitHub repository. Clone the repository to a Linux server. Run the script with the user list file as an argument. The HNG project is more than just an internship; it is a transformative experience that equips participants with the skills, knowledge, and confidence needed to thrive in the fast-paced tech industry. Honestly, I am enjoying it. Thanks for taking the time to read this far. Please kindly like and leave a comment. Thank you!

CSS: Aprendendo box model com analogias

Introdução Se você está estudando CSS, talvez já tenha se deparado com o termo box model....

https://dev.to/fhmurakami/css-aprendendo-box-model-com-analogias-5a9a

css, learning, beginners, braziliandevs

## Introdução Se você está estudando CSS, talvez já tenha se deparado com o termo _box model_. Caso ainda não tenha, não se preocupe, iremos abordar esse assunto nesse artigo. Basicamente todo elemento em uma página web é um retângulo chamado de _box_ (caixa), e daí vem o nome _box model_ ou _modelo de caixa_. Entendermos como funciona esse modelo é a base para conseguirmos criar layouts mais complexos com CSS, ou alinhar itens corretamente.  Ao inspecionar um elemento (clicando com o botão direito ou abrindo o **DevTools** com os atalhos Ctrl+Shift+C ou F12, dependendo do seu navegador), na aba _Computed_ (Calculado), você provavelmente irá ver a imagem a seguir: <figure> <a id="computed"></a>  <figcaption>Fig.1 - Propriedades do elemento (aba _Computed_)</figcaption> </figure> No próximo tópico iremos ver detalhadamente o que significa cada parte dessa imagem. ## Estrutura básica do **box model** Para ilustrar a estrutura básica do _box model_ irei utilizar como exemplo a construção de uma casa em um terreno. Essa ideia foi inspirada neste artigo [[1]][Ref1] (em inglês). As partes que compõem a estrutura do _box model_ são: ### **Conteúdo** (_Content_) O conteúdo se refere à parte mais central da [Fig.1][Fig1] em azul, e está relacionado ao conteúdo dentro de uma tag HTML, como por exemplo o texto em um parágrafo (**`<p>`**). O conteúdo é composto basicamente por duas propriedades, largura (`width`) e altura (`height`). No nosso exemplo, o conteúdo será a casinha abaixo ([Fig.2][Fig2]) (se você inspecionar a imagem da casa, verá que as medidas são as mesmas da [Fig.1][Fig1]). As dimensões da casa são 81px de largura e 93 px de altura. <figure> <a id="casa"></a>  <figcaption>Fig. 2 - Conteúdo (casa) e suas dimensões</figcaption> </figure> O conteúdo precisa estar dentro de uma estrutura HTML, portanto colocaremos nossa casinha dentro de um lote para representar esta estrutura: <figure> <a id="casa-lote"></a>  <figcaption>Fig. 3 - Casa posicionada no centro do lote</figcaption> </figure> ### **Preenchimento** (_Padding_) A parte em verde da [Fig.1][Fig1] é a propriedade chamada de `padding` (preenchimento), que cria um espaço ao redor do conteúdo. O `padding` é demonstrado pela parte de terra, onde será o jardim, por exemplo: <figure> <a id="padding"></a>  <figcaption>Fig. 4 - Padding adicionado como uma área de terra ao redor da casa</figcaption> </figure> ### **Borda** (_Border_) A seguir temos a propriedade `border`, ou borda, que é responsável por delimitar nosso conteúdo e está representada pela cor amarela na [Fig.1][Fig1]. A borda é a última propriedade do nosso elemento que pode ser vista. A borda pode ser representada como o muro ou, no nosso caso, a cerca da casa: <figure> <a id="margin"></a>  <figcaption>Fig. 5 - Border (Cerca) adicionada ao redor do padding</figcaption> </figure> ### **Margem** (_Margin_) Por fim, temos a propriedade `margin`, em laranja ([Fig.1][Fig1]), que inclui uma área vazia ao redor do nosso elemento. Como pode ser visto na imagem: <figure> <a id="margin"></a>  <figcaption>Fig. 6 - Margem adicionada ao elemento, criando uma área vazia ao redor da borda</figcaption> </figure> Neste caso, reduzimos o `padding` para que a margem pudesse ser representada na imagem. ## A propriedade **`box-sizing`** Agora que conhecemos a estrutura do _box model_, podemos abordar a propriedade `box-sizing`. Essa propriedade nos permite dizer ao navegador como ele deve calcular a altura e a largura do elemento. Temos apenas 2 valores possíveis: ### content-box Este é o valor padrão, em que a altura e a largura do elemento incluem apenas o conteúdo. Portanto, se tivermos um conteúdo com `height`(altura) e `width`(largura) de 100px, mais 10px de `padding`, mais 5px de `border` e 5 de `margin`, veremos que o tamanho do nosso elemento mudou de 100px para 130px: <figure> <a id="content-box-example"></a>  <figcaption>Fig. 7 - Div com 100 px de altura e largura, 10px de padding, 5px de border e 5px de margin utilizando o valor padrão `content-box`</figcaption> </figure> Veja o código aqui: {% codepen https://codepen.io/fhmurakami/pen/QWXLdpX %} Isso ocorre pois as propriedades _`height`_ e _`width`_, são aplicadas somente ao conteúdo (a parte azul da [Fig.1][Fig1], lembra?). Porém adicionamos ainda o `padding`, a `border` e a `margin`: 100px (`height`/`width`) + 2 * 10px (`padding`) + 2 * 5px (`border`) + 2 * 5px (`margin`) = **140px** > #### **Atenção!** :warning: > Ué?! :thinking: > > A imagem mostra o elemento com 130px e não 140px! > Exato! Lembre-se que a `margin` é uma propriedade externa (ou um espaço vazio em volta) do elemento e por isso não deve ser somada à altura e à largura do mesmo. Podemos pensar que com a propriedade `box-sizing` com o valor `content-box`, nosso elemento vai crescendo conforme adicionamos mais "camadas". Para explicar, utilizarei mais uma analogia: Imagine um balão, daqueles de festa de criança, com doces dentro. <center> <table> <tr> <td> <figure> <a id="baloon"></a> <img alt="Balão onde iremos colocar os doces" src="https://dev-to-uploads.s3.amazonaws.com/uploads/articles/jx739awww0jowwoonp8o.png" /> <figcaption>Fig. 8 - Balão de festa (<code>border</code>)</figcaption> </figure> </td> <td> <figure> <a id="candies"></a> <img alt="Doces" src="https://dev-to-uploads.s3.amazonaws.com/uploads/articles/15qcojcdwti9cpc9ops0.png" /> <figcaption>Fig. 9 - Doces (<code>content</code>)</figcaption> </figure> </td> </tr> <tr> <td colspan="2"> <figure> <a id="baloon-candies"></a> <img alt="Balão cortado para exibir os doces dentro" src="https://dev-to-uploads.s3.amazonaws.com/uploads/articles/23d4459r9hpc24dinodj.png" /> <figcaption>Fig. 10 - Balão com os doces dentro</figcaption> </figure> </td> </tr> </table> </center> Os doces serão o nosso conteúdo, com uma altura e largura fixos. Para que seja possível estourar o balão, vamos adicionar um `padding` (ar) dentro do balão. O balão em si, é a `border` e a `margin` é todo o espaço em volta do balão: <figure> <a id="baloon-full"></a> <img alt="Balão pendurado no teto com espaço vazio ao seu redor" src="https://dev-to-uploads.s3.amazonaws.com/uploads/articles/huhrywjs718o6twheanr.png" /> <figcaption>Fig. 11 - Doces (<code>content</code>), ar (<code>padding</code>), balão (<code>border</code>), espaço em volta do balão (<code>margin</code>)</figcaption> </figure> Viu como nosso elemento foi crescendo conforme adicionamos mais propriedades? Ou se adicionarmos mais ar (`padding`) ao balão? Outro exemplo de `content-box` utilizando analogia: um saco de pipoca no microondas, onde temos inicialmente o `content` (milho), a `border` (saco de papel) e `margin` (espaço interno do microondas). Porém ao aquecer, lentamente um `padding`(ar/vapor dentro do saco) vai sendo adicionado. ### border-box O outro valor possível para a propriedade `box-sizing` é o `border-box`. Ele é muito útil quando você quer ter certeza do espaço que seu elemento irá ocupar na página, pois ao invés de atribuir a altura e a largura apenas ao conteúdo, ele utiliza o elemento todo (`content + padding + border`). Isso ajuda na criação de layouts responsivos, pois garantimos os elementos terão o tamanho exato que for definido mesmo utilizando medidas relativas (`%`, `em`, `rem` etc.). Utilizando o mesmo exemplo da [Fig.7][Fig7], porém adicionando a propriedade `box-sizing: border-box;` teremos um elemento final com os 100px de altura e largura como definimos anteriormente. <figure> <a id="border-box-example"></a> <img alt="Div com 100 px de altura e largura, 10px de padding, 5px de border e 5px de margin, porém desta vez utilizando o valor border-box" src="https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ga0e6zyju1aqknvc71vy.png"/> <figcaption> Fig. 12 - Div com 100 px de altura e largura, 10px de padding, 5px de border e 5px de margin, porém desta vez utilizando o valor <code>border-box</code> </figcaption> </figure> A diferença é que agora nosso conteúdo reduziu para 70px de altura e largura para não ultrapassar os 100px no total. <figure> <a id="computed-border-box"></a> <img alt="Imagem da aba computed mostrando que o conteúdo foi reduzido para 70px de altura e largura" src="https://dev-to-uploads.s3.amazonaws.com/uploads/articles/gn7pkcr45w7nup242uoi.png" /> <figcaption> Fig. 13 - Aba <code>computed</code> ao inspecionar o elemento </figcaption> </figure> Vejo o código aqui: {% codepen https://codepen.io/fhmurakami/pen/wvLwggR %} Neste caso, devemos pensar em algo em que as medidas finais não possam ultrapassar um determinado tamanho. Para isso utilizaremos uma caixa térmica como o tamanho máximo, sendo assim, a caixa representará a `borda` do nosso elemento: <figure> <a id="cooler-vazio"></a>  <figcaption> Fig. 14 - Caixa térmica (`border`) </figcaption> </figure> O `conteúdo` será a bebida que queremos gelar, e o gelo é o `padding`: <center> <table> <tr> <td> <figure> <a id="barril-chopp"></a> <img alt="Barril de chopp" src="https://dev-to-uploads.s3.amazonaws.com/uploads/articles/rq41pe25twoxpbzli7g2.png" /> <figcaption>Fig. 15 - Barril de chopp (<code>content</code>)</figcaption> </figure> </td> <td> <figure> <a id="gelo"></a> <img alt="Cubos de gelo" src="https://dev-to-uploads.s3.amazonaws.com/uploads/articles/3soshxk0pfw00i2iju2a.png" /> <figcaption>Fig. 16 - Cubos de gelo (<code>padding</code>)</figcaption> </figure> </td> </tr> <tr> <td colspan="2"> <figure> <a id="cooler-cheio"></a> <img alt="Caixa térmica com a bebida e o gelo" src="https://dev-to-uploads.s3.amazonaws.com/uploads/articles/7rpvts1fh4n098sntuw7.png" /> <figcaption>Fig. 17 - Caixa térmica com a bebida e o gelo</figcaption> </figure> </td> </tr> </table> </center> Perceba que quanto mais gelo colocarmos, menor será a bebida que conseguiremos gelar. Como não podemos ter um conteúdo com medidas negativas, o menor tamanho possível será de 0px. Porém, supondo que nossa caixa tenha 100px de `altura` por 120px de `largura` , e definirmos um `padding` de 60px, ao todo teremos 120px de gelo tanto na horizontal quanto na vertical, ou seja, o gelo irá transbordar a caixa térmica. <figure> <a id="padding-overflow"></a>  <figcaption> Fig. 18 - Gelo transbordando a o limite máximo (altura) da caixa térmica </figcaption> </figure> O mesmo acontece com nosso elemento HTML: <figure> <a id="border-box-overflow"></a>  <figcaption> Fig. 19 - Inspecionando o elemento é possível ver que, ao adicionar um padding maior do que o tamanho total do elemento, o conteúdo foi reduzido para 0x0 px e a altura aumentou para 150px, mesmo com o `box-sizing: border-box` </figcaption> </figure> Vejo o código aqui: {% codepen https://codepen.io/fhmurakami/pen/mdZbJZp %} ## Conclusão Agora que você já conhece a estrutura básica do _Box Model_, e a propriedade `box-sizing`, ficará mais fácil entender como os elementos se comportam na sua página web e saber quando usar cada um dos valores (`content-box` e `border-box`). Se você inspecionar os elementos dos sites que utiliza no dia-a-dia, verá que a maioria utiliza `border-box` para seus elementos, pois essa propriedade tem facilitado muito o design responsivo. :) Parabéns por ter chegado até aqui!

Track your performance using Habitica, Timestream and Grafana

Habitica is an excellent tool for keeping yourself sticking to what you have planned for yourself....

https://pabis.eu/blog/2024-07-05-Track-Habitica-Timestream-Grafana.html

habitica, grafana, lambda, timestream

Habitica is an excellent tool for keeping yourself sticking to what you have planned for yourself. Although it doesn't work for everyone, it is nevertheless worth trying. (This is my third try in using Habitica and it seems to be working with the longest streak of 949 days.) As discussed in the previous post, Habitica has an API that lets you retrieve data from the app and perform actions. As a warmup, [we created a simple Lambda script](https://pabis.eu/blog/2024-06-30-Habitica-Item-Seller-Lambda-SAM.html) that sells excess items in our Habitica inventory. Today, we are going to create a similar scheduled Lambda function that will collect statistics of our profiles and store them in Amazon Timestream database. Later we will be able to view the data using Grafana. Creating Timestream database and table -------------------------------------- This is a very simple step. In the same `template.yaml` [file as before](https://pabis.eu/blog/2024-06-30-Habitica-Item-Seller-Lambda-SAM.html), place new resources for Timestream. It is a standard CloudFormation resource and doesn't take too many parameters. I decided to set the memory storage to 7 days as our function will not collect so much data so it won't cost you a lot. ```yaml # Database and table for collecting Habitica statistics HabiticaStatsTimestream: Type: AWS::Timestream::Database Properties: DatabaseName: HabiticaStats HabiticaStatsTable: Type: AWS::Timestream::Table Properties: TableName: HabiticaStatsTable DatabaseName: !Ref HabiticaStatsTimestream RetentionProperties: MemoryStoreRetentionPeriodInHours: 168 MagneticStoreRetentionPeriodInDays: 365 ``` New Lambda function ------------------- I will base the new function on the previous work. I will copy `auth.py` and duplicate the template from the item seller. The new code will be in a new directory called `collect-stats`. First file `actions.py` will be used for API calls to Habitica. We will first define some constants and import `requests`. By default Habitica returns a lot of data for `stats` fields so we will filter out some of them. ```python import requests HABITICA_URL="https://habitica.com/api/v3" STATS_TO_GET = ['gp', 'exp', 'mp', 'lvl', 'hp'] ``` Now we can construct the function that will do the API call and return the statistics we want to track. It will also return username that we will use later as a dimension. It is not required but it is nice to have. ```python def get_stats(headers: dict) -> tuple[str, dict]: url = f"{HABITICA_URL}/user?userFields=stats" response = requests.get(url, headers=headers) code = response.status_code if code == 200: user = response.json()['data']['auth']['local']['username'] stats = response.json()['data']['stats'] stats = {k: v for k, v in stats.items() if k in STATS_TO_GET} return user, stats raise Exception(response.json()['message']) ``` Next function is also very simple. It will just construct appropriate objects to store in the Timestream table. We will use standard `boto3` library and iterate through all the measurements we want to save. ```python import boto3 def store_in_timestream(database: str, table: str, timestamp: float, username: str, stats: dict): dimensions = [ {'Name': 'username', 'Value': username} ] client = boto3.client('timestream-write') records = [ { 'Dimensions': dimensions, 'MeasureName': stat, 'MeasureValue': str(value), 'MeasureValueType': 'DOUBLE', 'Time': str(int(timestamp * 1000)), 'TimeUnit': 'MILLISECONDS', } for stat, value in stats.items() ] client.write_records(DatabaseName=database, TableName=table, Records=records) ``` Now it's time to create `main.py` where we will glue together the two functions. It will retrieve all the needed configuration from environment variables, such as Timestream parameters and API key location. My function in the repository also has some logging so that I can see errors. ```python from actions import get_stats from store import store_in_timestream from auth import get_headers import os, datetime HEADERS = get_headers() DATABASE_NAME = os.getenv('DATABASE_NAME') TABLE_NAME = os.getenv('TABLE_NAME') def lambda_handler(event, context): current_utc = datetime.datetime.now(datetime.UTC) current_utc_string = current_utc.strftime("%Y-%m-%d %H:%M:%S %Z") # Such as 2024-07-03 21:10:05 UTC try: username, stats = get_stats(HEADERS) store_in_timestream(DATABASE_NAME, TABLE_NAME, current_utc.timestamp(), username, stats) except Exception as e: return { "statusCode": 500, # Mark as error "body": f"{current_utc_string}: {str(e)}" } return { "statusCode": 200, # Success "body": f"Collected statistics for time {current_utc_string}." } ``` Adding the function to SAM -------------------------- I decided that my function will collect the data every 30 minutes. I don't think that anything more granular is necessary and 30 minutes gives smooth enough graph. In the same template as before, we need to reference the secret stored in [Secrets Manager](https://pabis.eu/blog/2024-06-30-Habitica-Item-Seller-Lambda-SAM.html) as well as the Timestream database and table. ```yaml HabiticaCollectStats: Type: AWS::Serverless::Function Properties: CodeUri: collect_stats/ Handler: main.lambda_handler Runtime: python3.12 Architectures: - arm64 Policies: - AWSSecretsManagerGetSecretValuePolicy: SecretArn: !Ref HabiticaSecret Environment: Variables: HABITICA_SECRET: !Ref HabiticaSecret DATABASE_NAME: !Ref HabiticaStatsTimestream TABLE_NAME: !Select [ "1", !Split [ "|", !Ref HabiticaStatsTable ] ] Events: Schedule30Min: Type: Schedule Properties: Schedule: cron(*/30 * * * ? *) Enabled: true ``` Because CloudFormation returns reference to the table as `Database|Table`, we unfortunately have to split it and `!Select` the second element. However, this is not the end! If we now wait for the function to run, we will see something unexpected. ``` Error collecting stats at 2024-06-30 19:45:14 UTC: An error occurred (AccessDeniedException) when calling the DescribeEndpoints operation: User: arn:aws:sts::1234567890:assumed-role/habitica-item-seller-HabiticaCollectStatsRole... is not authorized to perform: timestream:DescribeEndpoints ``` SAM doesn't have policy templates for Timestream, similar to the one we use for Secrets Manager. However, we can define an inline policy directly. In the `Policies` section add the following using a `Statement` object. ```yaml Policies: - AWSSecretsManagerGetSecretValuePolicy: SecretArn: !Ref HabiticaSecret - Statement: - Effect: Allow Action: - timestream:WriteRecords - timestream:DescribeTable Resource: !GetAtt HabiticaStatsTable.Arn - Effect: Allow Action: - timestream:DescribeEndpoints Resource: "*" ``` In the directory you have `template.yaml` run `sam build`. If this is the first time running SAM, use `sam deploy --guided` to deploy the stack. Otherwise just `sam deploy` is sufficient. All updates to the Lambda side of the project can be found in the new `v2` tag in here: [https://github.com/ppabis/habitica-item-seller/tree/v2](https://github.com/ppabis/habitica-item-seller/tree/v2). Querying Timestream for collected records ----------------------------------------- If everything looks correct in CloudWatch logs and there are no errors in the Monitoring tab of the Lambda function, you can peek into the Timestream database. In the Timestream console, select `Tables` in the left pane, click on your table (verify if you are in the right region) and in the top-right `Actions` select `Query`. Run the following example query. Depending on your schedule, you should see some records.  ```sql SELECT * FROM "HabiticaStats"."HabiticaStatsTable" WHERE time between ago(3h) and now() ORDER BY time DESC LIMIT 10 ``` Configuring Grafana ------------------- I created a Terraform repository for spawning Grafana on EC2 instance. It is easier to manage files than in CloudFormation. I will just install Docker and `docker-compose` on the instance and run Grafana. Because it will have authentication it is smart to have any means of encryption so I will put it behind Nginx with self-signed certificate. You can risk using plaintext, or use VPN, SSH tunnel or ALB alternatively. But let's start with the configuration. I will skip VPC creation part, providers and jump directly to the interesting parts. For the complete project follow [this link](https://github.com/ppabis/grafana-ec2-docker/tree/main). First, we will create Grafana config that will set up our admin user and password. It will also allow any origin to connect as I did not configure any domains. ```ini [server] enforce_domain = false [security] disable_initial_admin_creation = false admin_user = secretadmin admin_password = PassWord-100-200 cookie_secure = true cookie_samesite = none ``` Next up is Nginx configuration. This is just a simple reverse proxy with TLS. You can also set up HTTP to HTTPS redirection. The host name in `proxy_pass` needs to match the name of the container in `docker-compose.yml` which we will define next. We will handle certificates in a later stage. ```nginx server { listen 443 ssl; server_name _; ssl_certificate /etc/nginx/ssl/selfsigned.crt; ssl_certificate_key /etc/nginx/ssl/selfsigned.key; location / { proxy_pass http://grafana:3000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } ``` Next we will create Docker compose file. It will create a common network for the two containers, mount the configuration and data directories and expose Nginx's port so that it is accessible from the Internet. For Grafana, it is also important to set the user and group that will be able to write to the directory. The environment variables will be picked up from user data script at the later stage. ```yaml --- networks: habitica-stats: driver: bridge services: grafana: image: grafana/grafana:latest volumes: - /opt/grafana:/var/lib/grafana - /opt/grafana.ini:/etc/grafana/grafana.ini user: "${RUN_AS_ID}:${RUN_AS_GROUP}" networks: - habitica-stats restart: always nginx: image: nginx:latest volumes: - /opt/nginx/nginx.conf:/etc/nginx/conf.d/default.conf - /opt/nginx/selfsigned.crt:/etc/nginx/ssl/selfsigned.crt - /opt/nginx/selfsigned.key:/etc/nginx/ssl/selfsigned.key ports: - 443:443 networks: - habitica-stats restart: always ``` All of the above files are small and can be stored in SSM Parameter Store. It is more convenient than copying them over through S3. In Terraform I defined three parameters. I suggest keeping the Grafana configuration as `SecureString` as it contains the password. ```terraform resource "aws_ssm_parameter" "grafana_ini" { name = "/habitica-stats/grafana/ini" type = "SecureString" value = file("./resources/sample.ini") } resource "aws_ssm_parameter" "nginx_conf" { name = "/habitica-stats/nginx/conf" type = "String" value = file("./resources/nginx.conf") } resource "aws_ssm_parameter" "docker_compose" { name = "/habitica-stats/docker_compose" type = "String" value = file("./resources/docker-compose.yml") } ``` Now, as we know the names of the parameters we can define our user data file. It will run as we create the instance and download all the parameters to their respective files. Important to note is that this instance **requires** IPv4 connection to the Internet. I tried using just IPv6 and it was shaving a yak to copy over everything with S3 or other means. GitHub doesn't support IPv6. Grafana plugins are not accessible through IPv6. So either give your instance a public IPv4 address or use NAT Gateway. ### The script below will do the following: - Install Docker and `docker-compose` - Create configuration for Grafana - Create configuration for Nginx including self-signed SSL - Start the containers using compose file ```bash #!/bin/bash # Docker and docker-compose installation yum install -y docker systemctl enable --now docker curl -o /usr/local/bin/docker-compose -L "https://github.com/docker/compose/releases/download/v2.28.1/docker-compose-linux-aarch64" chmod +x /usr/local/bin/docker-compose # Grafana configuration useradd -r -s /sbin/nologin grafana mkdir -p /opt/grafana chown -R grafana:grafana /opt/grafana aws ssm get-parameter --name ${param_grafana_ini} --with-decryption --query Parameter.Value --output text > /opt/grafana.ini chown grafana:grafana /opt/grafana.ini # Nginx configuration mkdir -p /opt/nginx openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /opt/nginx/selfsigned.key -out /opt/nginx/selfsigned.crt -subj "/CN=grafana" aws ssm get-parameter --name ${param_nginx_conf} --query Parameter.Value --output text > /opt/nginx/nginx.conf # Run the stack # Docker compose picks up environment variables just as shell scripts export RUN_AS_ID=$(id -u grafana) export RUN_AS_GROUP=$(id -g grafana) aws ssm get-parameter --name ${param_docker_compose} --query Parameter.Value --output text > /opt/docker-compose.yml docker-compose -f /opt/docker-compose.yml up -d ``` IAM profile for the instance ---------------------------- In order to allow Grafana to read from Timestream, we will need to grant permissions to the EC2 instance. I attached two policies for simplicity: `AmazonSSMManagedInstanceCore` which will allow access to SSM Parameters and in case we need to debug to SSM Session Manager, and `AmazonTimestreamReadOnlyAccess` that allows Grafana to not only query the database but also list databases and tables that will make the UI usable for configuration. You can adapt it to your needs by importing exporting the outputs from SAM template and importing them in Terraform using data provider `aws_cloudformation_export`. ```terraform resource "aws_iam_instance_profile" "grafana_ec2_profile" { name = "grafana_ec2-profile" role = aws_iam_role.grafana_ec2_role.name } resource "aws_iam_role" "grafana_ec2_role" { name = "grafana_ec2-role" assume_role_policy = jsonencode({ Version = "2012-10-17" Statement = [{ Effect = "Allow" Principal = { Service = "ec2.amazonaws.com" } Action = "sts:AssumeRole" }] }) } resource "aws_iam_role_policy_attachment" "ssm" { role = aws_iam_role.grafana_ec2_role.name policy_arn = "arn:aws:iam::aws:policy/AmazonSSMManagedInstanceCore" } resource "aws_iam_role_policy_attachment" "timestream" { role = aws_iam_role.grafana_ec2_role.name policy_arn = "arn:aws:iam::aws:policy/AmazonTimestreamReadOnlyAccess" } ``` Creating new instance --------------------- For the instance we also need a security group. I will allow HTTPS traffic from any IPv6 address and from my home IPv4 address on port 443. My AMI choice is standard Amazon Linux 2023 and I will use a Graviton instance as it's cheaper. If you want to keep it in your free tier, use `t2.micro` or `t2.nano`. ```terraform resource "aws_security_group" "grafana_sg" { vpc_id = aws_vpc.vpc.id name = "grafana-sg" egress { from_port = 0 to_port = 0 protocol = "-1" cidr_blocks = ["0.0.0.0/0"] ipv6_cidr_blocks = ["::/0"] } ingress { from_port = 443 to_port = 443 protocol = "tcp" # This will allow anyone to acecss via HTTPS when using IPv6 or just your IPv4 ipv6_cidr_blocks = ["::/0"] cidr_blocks = ["12.13.14.15/32"] } } ``` For IPv4 I will associate a public IP address. If you have a running NAT Gateway it might be a better idea to use it instead. The user data script is a template that should be filled with the names of the SSM parameters we created before. I will also produce outputs of the IPs concatenated with `https://` so that I have easy access to the service. ```terraform resource "aws_instance" "grafana" { ami = data.aws_ssm_parameter.al2023.value instance_type = "t4g.micro" vpc_security_group_ids = [aws_security_group.grafana_sg.id] subnet_id = aws_subnet.public.id associate_public_ip_address = true ipv6_address_count = 1 iam_instance_profile = aws_iam_instance_profile.grafana_ec2_profile.name user_data = templatefile("./resources/user-data.sh", { param_docker_compose = aws_ssm_parameter.docker_compose.name, param_nginx_conf = aws_ssm_parameter.nginx_conf.name, param_grafana_ini = aws_ssm_parameter.grafana_ini.name }) tags = { Name = "grafana-ec2" } } output "site_ipv6" { value = "https://[${aws_instance.grafana.ipv6_addresses[0]}]" } output "site_ipv4" { value = "https://${aws_instance.grafana.public_ip}" } ``` The completed Grafana instance project can be [found here](https://github.com/ppabis/grafana-ec2-docker/tree/main). It might take some time to boot and create all the containers, so leave it for a few minutes after all the Terraform processes are done. ```bash $ tofu init $ tofu apply ``` Configuring Grafana ------------------- Now the final part is configuring Grafana connections and dashboards. Go to the address that you got as an output. The certificate is self-signed so you will get a warning. Accept it and log in with the credentials you set up in `grafana.ini`.  Select `Connections` -> `Add new connection`. Search for Timestream. Install it in the top-right and again in the same spot click `Add new data source`.  The first thing you have to select is a region where your Timestream database is. Then you should be able to select the database and table from the dropdown.  Once you added the data source, you can create a new dashboard. On the left hand side click `Dashboards` and create a new one. Select Timestream data source and in the query editor write such query. You can use it for every graph you create. Change the measured value on the left to choose. Click `Apply` to save the graph to the dashboard. ```sql SELECT * FROM $__database.$__table WHERE measure_name = '$__measure' ```  [*View better quality video here*](https://pabis.eu/assets/videos/grafana-habitica.mp4)  You can then create a dashboard that will track your habits and tasks progress as an overall overview. You can also create a graph that will compare how well do your mornings look like (how much exp do you gain between 6 and 10 AM). To do this, set your graph type to bar chart and put the following long query. ```sql WITH morning_values AS ( SELECT date_trunc('day', time) AS day, measure_value::double AS value_at_time, CASE WHEN extract(hour from time) = 6 THEN 'value_at_6am' WHEN extract(hour from time) = 10 THEN 'value_at_10am' END AS time_period FROM $__database.$__table WHERE (extract(hour from time) = 6 OR extract(hour from time) = 10) AND measure_name = '$__measure' ), aggregated_values AS ( SELECT day, MAX(CASE WHEN time_period = 'value_at_6am' THEN value_at_time ELSE NULL END) AS value_at_6am, MAX(CASE WHEN time_period = 'value_at_10am' THEN value_at_time ELSE NULL END) AS value_at_10am FROM morning_values GROUP BY day ) SELECT value_at_10am - value_at_6am, day FROM aggregated_values ORDER BY day ASC ``` It will do the following: first it will find all the measurements that happened at 6AM UTC or 10AM UTC (6:00-6:59 to be exact). Then it will take the largest of the values (so more likely 6:59 than 6:00) and pass it to another query that will group those values it by days. So we will have 1st July with two values, 2nd of July with two values, etc. Finally, for each day we will subtract 6AM measured value from 10AM measured value. Of course I didn't write this query myself. But I like the effect nevertheless. Because of UTC storage I expanded the window from 5AM to 12PM.

Le `DiscriminatorMap` de Doctrine permet une gestion efficace des entités héritées. Nous allons prendre l'exemple simple d'une classe `Vehicle` pour créer deux classes qui vont en hériter : `Bike` et `Car` qui ont des attributs différents mais auront les mêmes que `Vehicle`. Avec Api-platform, on pourra faire un `GET /vehicles` pour avoir tous les vehicules `GET bikes` pour tous les bikes et `GET /cars` ```php <?php namespace App\Entity; use ApiPlatform\Doctrine\Orm\Filter\OrderFilter; use ApiPlatform\Doctrine\Orm\Filter\SearchFilter; use ApiPlatform\Metadata\ApiFilter; use ApiPlatform\Metadata\ApiResource; use App\Repository\VehicleRepository; use Doctrine\ORM\Mapping as ORM; #[ORM\Entity(repositoryClass: VehicleRepository::class)] #[ORM\InheritanceType('JOINED')] #[ORM\DiscriminatorColumn(name: 'discr', type: 'string')] #[ORM\DiscriminatorMap([ 'car' => Car::class, 'bike' => Bike::class ])] #[ApiResource] #[ApiFilter(OrderFilter::class)] class Vehicle { #[ORM\Id] #[ORM\GeneratedValue] #[ORM\Column] private ?int $id = null; #[ORM\Column(length: 255)] #[ApiFilter(SearchFilter::class, strategy: 'partial')] private ?string $brand = null; #[ORM\Column] private ?\DateTimeImmutable $createdAt = null; public function getId(): ?int { return $this->id; } public function getBrand(): ?string { return $this->brand; } public function setBrand(string $brand): static { $this->brand = $brand; return $this; } public function getCreatedAt(): ?\DateTimeImmutable { return $this->createdAt; } public function setCreatedAt(\DateTimeImmutable $createdAt): static { $this->createdAt = $createdAt; return $this; } } ``` ```php <?php namespace App\Entity; use ApiPlatform\Doctrine\Orm\Filter\OrderFilter; use ApiPlatform\Metadata\ApiFilter; use ApiPlatform\Metadata\ApiResource; use App\Repository\BikeRepository; use Doctrine\ORM\Mapping as ORM; #[ORM\Entity(repositoryClass: BikeRepository::class)] #[ApiResource] #[ApiFilter(OrderFilter::class)] class Bike extends Vehicle { #[ORM\Column] private ?bool $hasCarrier = null; public function hasCarrier(): ?bool { return $this->hasCarrier; } public function setHasCarrier(bool $hasCarrier): static { $this->hasCarrier = $hasCarrier; return $this; } } ``` ```php <?php namespace App\Entity; use ApiPlatform\Doctrine\Orm\Filter\OrderFilter; use ApiPlatform\Metadata\ApiFilter; use ApiPlatform\Metadata\ApiResource; use App\Repository\CarRepository; use Doctrine\ORM\Mapping as ORM; #[ORM\Entity(repositoryClass: CarRepository::class)] #[ApiResource] #[ApiFilter(OrderFilter::class)] class Car extends Vehicle { #[ORM\Column] private ?int $numberOfDoors = null; public function getNumberOfDoors(): ?int { return $this->numberOfDoors; } public function setNumberOfDoors(int $numberOfDoors): static { $this->numberOfDoors = $numberOfDoors; return $this; } } ``` Tout ce fait avec ```php #[ORM\InheritanceType('JOINED')] #[ORM\DiscriminatorColumn(name: 'discr', type: 'string')] #[ORM\DiscriminatorMap([ 'car' => Car::class, 'bike' => Bike::class ])] ``` `InheritanceType` peut également être `SINGLE_TABLE` ce qui signifie que vous n'aurez qu'une seule table pour toutes vos entités N'oubliez pas également sur les autres classes de rajouter `extends Vehicle` Fusée 🚀

CaaS vs SaaS - clouds clash. Good morning and welcome to your daily cloud forecast! Today, we're seeing a dramatic showdown in the digital skies with two major cloud formations taking center stage. On the west side, we have the formidable **[Content as a Service (CaaS)](https://thebcms.com/blog/content-as-a-service-caas)** cloud front, bringing with it a powerful API-driven storm, perfect for content delivery across multiple platforms. Meanwhile, from the East, the friendly but formidable **Software as a Service (SaaS)** system is moving in, promising ease of use and automatic updates for businesses of all sizes. As these two cloud giants clash, businesses everywhere are left wondering which model will best suit their needs. Will customizable and flexible CaaS bring clear skies to your content strategy? Or will user-friendly SaaS shower your operations with simplicity and efficiency? But wait! This isn't your typical weather report; it's the ultimate showdown in the digital skies. In this battle of **CaaS vs SaaS**, which cloud will reign supreme? Stay tuned as we dive into this full comparison of **CaaS vs SaaS**, exploring features, use cases, and advantages. Let's get ready to weather the storm! ## What is CaaS **Content as a Service (CaaS)** is a cloud computing service model that delivers content through APIs. CaaS allows businesses to store, manage, and deliver content across various platforms and devices without worrying about the backend infrastructure. CaaS decouples content creation and management from its presentation, enabling developers to build applications that pull content from a central repository. ### Key Features of CaaS 1. **API-driven content delivery:** Content is accessed and delivered via APIs, allowing flexibility in presentation. 2. **Centralized content management:** A single repository that acts like a [Content Hub](https://thebcms.com/blog/content-hub-guide) for managing content, which can be distributed across multiple channels. 3. **Scalability:** Easily handle varying content loads and deliver content efficiently at scale. 4. **Customization:** Developers can use any programming language or framework to build applications. 5. **Flexibility:** Content can be reused across different platforms and devices, ensuring a consistent user experience. ## What is SaaS **Software as a Service (SaaS)** is a cloud service model where software applications are delivered over the internet on a subscription basis. Users can access and use the software without worrying about installation, maintenance, or infrastructure management. SaaS applications are hosted and managed by a service provider. ### Key Features of SaaS 1. **Accessibility:** Access applications from any device with an internet connection. 2. **Subscription model:** Pay-as-you-go pricing without the need for large upfront investments. 3. **Automatic updates:** The provider handles updates and maintenance, ensuring users always have the latest features. 4. **Scalability:** Easily add or remove users and services as needed. 5. **Security:** Providers implement security measures to protect user data. ## CaaS vs SaaS: Differences between two clouds Since both clouds do the same, providing services, it is crucial to understand their roles in cloud computing. So, let’s start with a full comparison, exploring features, use cases, and even solutions on leveraging both approaches. ## CaaS vs SaaS- Full comparison Let’s start the battle. I’ll try to keep the score. ### CaaS vs SaaS- Round 1: Purpose  **CaaS:** Focuses on the management and delivery of content. CaaS is designed to handle the creation, storage, and distribution of content across multiple channels, making it ideal for organizations that need to manage and deliver content flexibly and scalable. **SaaS:** Provides software applications over the internet for various functions. SaaS delivers complete software solutions over the internet, covering a wide range of applications, from office software to customer relationship management (CRM) tools, simplifying end-user access and use. **Score:** - CaaS: 1 - SaaS: 1 ### Round 2: Content Delivery  **CaaS**: Uses APIs to deliver content to any front-end, offering flexibility. CaaS decouples content storage from presentation, allowing developers to use APIs to fetch and display content in any framework or device. This ensures that content is accessible and reusable across various platforms. **SaaS**: Includes built-in user interfaces for specific applications. SaaS applications come with integrated user interfaces tailored for specific tasks, making them easy to use but less flexible in terms of customization and content reuse. **Score:** - CaaS: 2 - SaaS: 1 ### Round 3: Flexibility **CaaS:** Highly flexible, enabling content reuse and repurposing across multiple channels. CaaS supports structured content to be easily reused and adapted for different channels and contexts, providing a high degree of flexibility in content management and delivery. - **SaaS:** Generally designed for specific functional needs without extensive content modularity. SaaS solutions are built to address particular functional needs, offering predefined features and interfaces that may not support extensive content customization or reuse. **Score:** - CaaS: 3 - SaaS: 1 ### Round 4: Scalability **CaaS:** Scalable for handling large volumes of content across various platforms. CaaS platforms are designed to manage and distribute large amounts of content efficiently, making them suitable for organizations with significant content delivery needs. **SaaS:** Scalable for user access and software functionality. SaaS solutions can easily scale to accommodate more users and additional features, ensuring that software performance remains robust as the user base grows. **Score:** - CaaS: 3 - SaaS: 2 ### Round 5: Management **CaaS:** Provides robust digital asset management (DAM), collaborative workflows, and lifecycle management. CaaS platforms include advanced features for managing content assets, supporting collaborative content creation, and lifecycle management to streamline content operations. **SaaS:** Simplifies access and use of software applications, with updates and maintenance handled by the provider. SaaS providers take care of software updates and maintenance, freeing users from the burden of managing software infrastructure and allowing them to focus on using the applications. **Score:** - CaaS: 4 - SaaS: 3 ### Round 6: Infrastructure **CaaS:** Decouples content creation/storage from presentation, requiring a distributed data delivery platform. CaaS architecture separates the backend content repository from the frontend presentation layer, using a distributed data delivery platform to ensure fast and efficient content access. **SaaS:** Hosts software on the provider's servers, accessed via the internet. SaaS applications are hosted on the provider's infrastructure, making them accessible from anywhere with an internet connection and reducing the need for local installations. **Score:** - CaaS: 4 - SaaS: 4 ### Round 7: Software access Works similarly to SaaS, providing all content through a single outlet. CaaS centralizes content storage and delivery, ensuring that content is consistently available and easy to manage across different channels. **SaaS is** simplifying software access for networks with multiple users. SaaS's subscription model allows for easy and widespread software access, enabling all users in a network to use the software without the hassle of individual installations. **Score:** - CaaS: 5 - SaaS: 5 ### Round 8: Speed **CaaS:** Accelerates content delivery and management processes by centralizing content access. With CaaS, content can be quickly updated and deployed across various channels, reducing the time and effort required to manage content. **SaaS:** Speeds up software deployment across networks, as all computers gain access to the software program at once. SaaS allows for rapid deployment of software across an entire organization, ensuring that all users have immediate access to the latest features and updates without delay. **Score:** - CaaS: 6 - SaaS: 6 As you can see, the score is even, so how to leverage both approaches in your business? ## Headless CMS: Rainbowing CaaS and SaaS In this cloud battle, it's a tie score between CaaS and SaaS. Enter Headless CMS – the solution to leverage the best features of both models.

typescript, setup, javascript, webdev

### TypeScript is JavaScript with syntax for types. TypeScript is a strongly typed programming language that builds on JavaScript, giving you better tooling at any scale. `.ts` is the extension of TypeScript file. ### 1. Setup - Before installing TypeScript on your system, first you need to install Node.js. You can check the [official documentation](https://nodejs.org/en/download/package-manager) for installating it. - Type the following command to check to ensure Node.js is install. The command gives out the Node.js version. ```shell > node --version ``` - Example:  - Create a new directory and go inside it. ```shell > mkdir code && cd code ``` - Initialize `package.json` file. Its a file which contains all the packages or dependencies install for the application. ```shell > npm init -y ``` - Install TypeScript ```shell > npm install typescript --save-dev ``` - `--save-dev` flag indicate we are installing TypeScript for development purpose and we don't need this package for production. - Initialize [TypeScript config file](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html). ```shell > npx tsc --init ``` ### 2. Set Up Project - Create new files and folders inside the `code` folder. ```shell > touch index.html > mkdir src dest > touch src/main.ts ``` - Folders and files tree  - **NOTE:** Browser can only understand JavaScript, so you need to compile the TypeScript into Javascript. - Specify where to output the compile JavaScript. Customize the `tsconfig.json` file to output inside the `.dest` folder. ```json // tsconfig.json ... "outDir": "./dest", /* Specify an output folder for all emitted files. */ ... ``` - The `...` three dots indicates their is more code. - Create a script that will watch your TypeScript file changes and automatically compile it into JavaScript. We will create a new script `start` inside the `package.json` file. ```json // package.json { "name": "code", "version": "1.0.0", "main": "index.js", "scripts": { "start": "tsc --watch" }, "keywords": [], "author": "", "license": "ISC", "description": "", "devDependencies": { "typescript": "^5.5.3" } } ``` - We will add some code inside our TypeScript file `src/main.ts` ```JavaScript const username: string = "Jane Doe"; console.log(`Hello, ${username}!`) ``` - Now, we will run the `start` script to watch the TypeScript file changes. ```shell > npm run start ``` - The `start` script command will automatically create a new file called `main.js` inside the `dest` folder which is our compiled JavaScript file. - Inside our `index.html` we will link our compiled JavaScript file and open it on the browser. Then, check the console to verify the message is logged. ```HTML <!-- index.html --> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>TypeScript Project Set Up</title> </head> <body> <h1>Press <code>F12</code> and check your browser console. There you will see the message which we have written.</h1> <script src="./dest/main.js"></script> </body> </html> ``` - Now, you can add your code and create your project!

## Why Create an API in Umbraco? APIs (Application Programming Interfaces) allow different software systems to communicate with each other. By creating an API in Umbraco, you can enable external applications to interact with your website’s content, offering enhanced functionality and improved user experiences. ## Prerequisites Before we start, ensure you have the following: - An Umbraco installation - Visual Studio or your preferred IDE ## Step 1: Set Up Your Umbraco Project First, ensure your Umbraco project is set up correctly. If you haven’t installed Umbraco yet, follow the steps mentioned [here](https://shekhartarare.com/Archive/2024/6/how-to-create-a-new-umbraco-project): ## Step 2: Create the API Controller Add a New Folder called Controllers: Add a new class file and name it MyAPIController.cs.  Write the API Code: ``` using Microsoft.AspNetCore.Mvc; using Umbraco.Cms.Web.Common.Controllers; namespace InstallingUmbracoDemo.Controllers { public class MyAPIController : UmbracoApiController { [HttpGet] public string GetGreeting() { return "Hello, Umbraco API!"; } } } ``` ## Step 3: Test Your API We don’t need to do anything about routing. Umbraco will automatically handle that for us. Now, let’s test our API: Open your browser and navigate to http://yourdomain.com/umbraco/api/myapi/getgreeting. You should see the message “Hello, Umbraco API!”.  ## Conclusion Creating an API in Umbraco is quick and easy, allowing you to expand the functionality of your website and integrate with external systems. By following the steps outlined in this guide, you can set up a basic API in just 5 minutes without the need for additional routing configuration. For more advanced Umbraco tutorials and tips, stay tuned to our blog and feel free to leave your questions in the comments!

Content as a Service: How to manage content on the cloud - CaaS guide

Whenever, wherever Content needs to be together Publish there, or publish here, CaaS is the deal,...

https://dev.to/momciloo/content-as-a-service-how-to-manage-content-on-the-cloud-caas-guide-3kb7

Whenever, wherever Content needs to be together Publish there, or publish here, CaaS is the deal, my dear There over, hereunder You'll never have to wonder Whatever form you need That's the promise of content as a service, my dear. This Shakira haiku song describes **content as a service** and explains its essence - a cloud-based approach that provides on-demand content delivery and management. What that means, why you should care, why it is important, and why you should consider this approach, how to choose the right CaaS model for your needs, key considerations- all answers you will find in this article. ## What is content as a service Content as a Service (CaaS) is a cloud-based content management model where organized content, in one place ([Content Hub](https://thebcms.com/blog/content-hub-guide)), can deliver that content to an unlimited number of frontends, such as the website, mobile apps, online stores, or "smart" devices. ### But, why “as service”? The "as a service" model in cloud computing, including CaaS, builds on the following concept: providing tools, resources, and expertise as a service rather than a product you need to manage yourself. In legacy CMSs, businesses would often need to invest heavily in infrastructure, software, and personnel to create and manage their content. With CaaS, this paradigm shifts towards a more service-oriented approach. **Simply put, work is done for you, not by you.** To understand that, let’s use music as an example one more time. (This time no Shakira).  The evolution of the music went from product to service. Music transitioned from being a physical product (records, tapes, CDs) to a digital product (MP3s, iTunes) and is now a service (Spotify, Apple Music). This shift to music as a service provides benefits such as instant access to vast libraries of music, personalized recommendations, and the convenience of streaming from any device, anywhere. Further, Spotify uses its data as a service. By leveraging extensive user data, Spotify can offer personalized playlists, recommendations, and insights, enhancing UX and engagement. This approach not only improves user satisfaction but also drives business growth by tailoring content to individual preferences and behaviors. Le-do-lo-le-lo-le, le-do-lo-le-lo-le. ## Content as a service benefits Here are some key reasons why the "as a service" model is attractive, especially in the context of CaaS: 1. **Reduced infrastructure costs**: With CaaS, you don’t need to invest in an extensive hardware and software infrastructure. The service provider handles all that, saving you money. 2. **Accessibility**: CaaS ensures your content is accessible across various devices, enhancing user experience and reach. 3. **Omnichannel content publishing**: Content can be seamlessly published across multiple channels, from websites and mobiles to social media platforms, ensuring consistent and widespread distribution. 4. **Mobile-friendly:** CaaS platforms ensure that content is optimized for mobile devices, improving engagement and usability. 5. **Affordable models**: Pay-as-you-go or subscription models make CaaS financially accessible, allowing businesses to scale their usage based on need. 6. **Connectivity**: Cloud-based services offer robust connectivity and real-time communication capabilities, essential for modern content management. 7. **Scalability and flexibility**: CaaS platforms can scale resources up or down based on demand, providing unparalleled flexibility ## What are the differences between Content as a Service and traditional content management Unlike [WordPress](https://thebcms.com/compare/wordpress-alternative) or Drupal, to manage content, the Content as a service strategy follows the following approaches: ### Structured content vs. page-based templates Structured content and page-based templates represent two distinct approaches to content management. WordPress, for example, often relies on page-based templates, which dictate how content should be organized and presented, which limits content to specific formats such as blogs. This approach can restrict the flexibility of content delivery. On the other hand, CaaS treats content as modular data that can be easily reused. CaaS breaks content down into reusable blocks, rather than large page templates, shifting the content infrastructure from a page-centric to a content-centric architecture. This allows for more dynamic and versatile content delivery. ### Coupled vs decoupled architecture Coupled architecture tightly binds the frontend presentation layer with the backend content repository, limiting content delivery to a single channel and often resulting in less flexibility. In contrast, CaaS supports a decoupled, or even headless, architecture that separates the frontend from the backend. This separation allows content to be delivered to any channel. By isolating content storage and delivery from content presentation, CaaS simplifies the CMS architecture, ensuring that each component performs its specific function without dependency on others. Learn more about headless: [All you need to know: Headless CMS](https://thebcms.com/blog/headless-cms-101) ### On-Premise vs. Cloud Simply put, the difference between on-premise and cloud software is location. An organization that uses on-premise software must handle the security, maintenance, updates, and scalability of its hardware infrastructure. As a subset of the Software as a Service (SaaS) model, Content as a Service shifts content storage and management to the vendor's cloud. Because of this, CaaS provides a more efficient, scalable content management experience than many traditional CMS solutions. ## How Content as a Service works  As part of the CaaS model, the CMS manages content assets independently of how they are delivered. Content creators upload content types—such as text blocks, photos, and videos —to a shared repository. By using APIs, developers can integrate specific types of content into websites, mobile, or other platforms, creating truly headless and highly scalable solutions. To do so, all CaaS solutions consist of two main components: ### Shared cloud repository  The importance of a cloud-based repository lies in its ability to centralize content management, offering scalability, accessibility, and efficiency. By storing assets in the cloud, organizations can easily distribute content globally, ensure real-time updates, and reduce the burden of maintaining on-premises infrastructure, ultimately leading to more agile and responsive content delivery. ### API-first approach to content distribution An API-first approach provides developers with access to content through high-performance APIs, ensuring integration and retrieval of content. It offers flexibility in the choice of front-end and content delivery frameworks, allowing developers to select the best tools for their needs. Want to see examples? Check out: - [Next CMS](https://thebcms.com/nextjs-cms) - [Gatsby CMS](https://thebcms.com/gatsby-cms) - [Nuxt CMS](https://thebcms.com/nuxt-cms) CaaS method guarantees the fastest possible speed for end users, enhancing their experience. The setup eliminates the need for connectors and optimizes performance and scalability by providing direct access to content at the distribution edge. But wait, are Caas and SaaS the same thing? 🤔 ## How CaaS compares with SaaS Even though both CaaS and SaaS are cloud-based models, they serve different purposes. SaaS provides software applications over the Internet, allowing users to access and use software without worrying about installation, maintenance, or infrastructure. Delivered or licensed through an online subscription, SaaS simplifies software access for networks with multiple users, eliminating the need for installing software on individual computers. On the other hand, CaaS focuses specifically on content management and delivery. Just as SaaS delivers software through a single outlet, CaaS provides all content through a single outlet, streamlining content delivery and management. For deeper understanding and comparison visit: CaaS vs SaaS Ok, we got this clear, next question is: How to adopt Content as a Service for your business? ## How to get started with Content as a Service Deciding to migrate to CaaS is only the first step. To be able to manage decoupled content, you still need a system to manage and deliver that content. Monolithic CMSs are trying to adapt to the CaaS model through add-ons and plugins, but they remain fundamentally webpage-centric platforms designed to control content presentation. To go full CaaS, consider investing in a headless, API-first CMS. Such a system is specifically designed around decoupling content, enabling its versatile use across various contexts and maximizing its potential. ## Key considerations while evaluating a CaaS headless CMS To choose the right CaaS model for your CMS should be a platform that can enable the following features and environment: ### APIs to fetch content Implementing a CaaS infrastructure that includes open, standards-based REST APIs, GraphQL, and SDKs for a flexible metadata model simplifies the development process. This low-code approach helps developers efficiently address complex content needs. ### Language independence A headless CMS should offer developers the freedom to build sites on any server in any programming language or framework. It should enable the distribution of content to unlimited sites or front-end environments, delivering it in formats such as JSON, RSS, custom templates, or XML. ### Personalize content The headless CMS should support content management in various formats, such as text, audio, and video. It should deliver personalized UXs, like dynamic user-based layouts for campaign landing pages or microsites, for each channel or front-end screen/page. ### Content modeling [Content modeling in a headless CMS](https://thebcms.com/blog/content-modeling-headless-cms) must provide features that support modular content creation, enabling reuse and repurposing of content across different channels. ### Composable architecture A [composable architecture](https://thebcms.com/blog/composable-architecture-example) allows the CMS to integrate and interoperate with other services and tools, providing a modular approach to building and scaling digital experiences. This flexibility enables organizations to select and assemble various components, such as authentication, analytics, and marketing automation, to create websites or apps that meet their specific needs. ## Use BCMS for your CaaS migration In the end, I'll leave you with one more consideration- try BCMS for CaaS. Why? BCMS headless CMS enables you to have reusable content available across websites, apps, and other digital platforms. By leveraging BCMS for CaaS, your organization can achieve faster content updates, improved UXs, and better scalability, all while reducing infrastructure costs. Embracing BCMS for CaaS truly makes CaaS the "Cloud 9" for content management. And for the end, a little more haiku: Whenever, wherever Content needs to be together Publish there, or publish here, BCMS is the deal, my dear There over, hereunder You got me over all screens, There's nothing left to fear If you really wanna try, try BCMS for free. Le-do-lo-le-lo-le, le-do-lo-le-lo-le.

https://dev.to/pagarevijayy/event-listeners-and-anchor-tag-3pdo

javascript, webdev, beginners, tutorial

Question: When does the anchor tag redirection happen given that multiple event listeners are attached to it? ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Event listeners and Anchor tag</title> </head> <body> <a id="demo" onclick="inlineHandler(event)" href="https://www.google.com">link demo</a> </body> <script> const inlineHandler = (e) => { console.log('inline Handler'); setTimeout(()=> { console.log('This will not get executed as redirection would have been occurred by then.'); }, 1000); } const link = document.getElementById('demo'); link.addEventListener('click', (e) => { console.log('event listener 1'); }) link.addEventListener('click', (e) => { console.log('event listener 2'); // e.preventDefault(); }) link.addEventListener('click', (e) => { console.log('event listener 3'); }) </script> </html> ```  **Learnings** - Inline handler always gets executed first. - Event listeners (for the same element) are handled in the order they are written. - Anchor tag redirection happens after the execution of all event listeners. - If any of the event listener triggers preventDefault (irrespective of the order) then redirection won't happen. Use case: Trigger analytics event on anchor tag link click. I'll leave the guesswork for async code upto you. For any doubts or discussions, please feel free to comment. Thanks!

https://dev.to/tatopetry/angularpt-desinscricoes-no-angular-quando-e-por-que-usar-109f

## Introdução Nos meus 6 anos trabalhando com Angular, uma pergunta recorrente que vejo aparecer, mesmo de devs com menos experiência, é: "Eu preciso me desinscrever aqui?" A resposta é: sim, na maioria dos casos. Mas nem sempre é tão simples assim. Neste artigo, quero entender quando e como usar as desinscrições no Angular. ## O que é desinscrição e por que é importante? Em resumo, desinscrever-se de um observable significa parar de receber notificações dele. Isso é crucial para evitar vazamentos de memória e garantir que seu aplicativo Angular funcione de forma eficiente. Imagine que você se inscreve para receber uma revista semanal com ofertas de um supermercado local. Essa revista é muito útil enquanto você mora perto do mercado, pois te mantém atualizado com as melhores promoções. Porém, se você se muda para outra cidade onde esse mercado não existe, continuar recebendo essa revista se torna desnecessário e só lota sua caixa de correio com conteúdo que você não vai usar. Nesse caso, é melhor cancelar a inscrição para evitar receber informações irrelevantes. No Angular, os observables funcionam de maneira semelhante. Quando você se inscreve em um observable, você está basicamente pedindo para receber notificações sempre que algo novo acontecer. Se você não precisa mais dessas notificações, é importante se desinscrever para evitar que o observable continue enviando notificações desnecessárias, o que pode levar a vazamentos de memória. ## Quando me desinscrever? - **Sempre que você não precisar mais das notificações do observable.** Por exemplo, se você está buscando dados para uma tela e, em seguida, navega para outra tela, não precisa mais das notificações do observable da tela anterior. - **Quando o componente que está criando a inscrição for destruído.** Isso geralmente acontece automaticamente quando você navega para outra tela, mas é importante verificar se há casos em que isso não acontece e, se necessário, desinscrever-se manualmente no `ngOnDestroy` do componente. ## Como me desinscrever? Existem diversas maneiras de se desinscrever de um observable no Angular. Aqui estão alguns dos métodos mais comuns: ### 1. Usando o método `unsubscribe()` Esse é o método mais básico e direto. Você pode armazenar a referência à inscrição em uma variável e chamá-la quando não precisar mais das notificações. ```typescript const subscription = myObservable.subscribe(data => { console.log(data); }); // ... algum tempo depois ... subscription.unsubscribe(); ``` ### 2. Usando o operador `takeUntil()` Esse operador permite que você se desinscreva de um observable quando outro observable for concluído. Isso é útil em situações em que você deseja se desinscrever de um observable principal quando um observable secundário for concluído. ```typescript import { Subject } from 'rxjs'; import { takeUntil } from 'rxjs/operators'; const subject = new Subject(); const subscription = myObservable.pipe( takeUntil(subject) ).subscribe(data => { console.log(data); }); // ... algum tempo depois ... subject.next(); ``` ### 3. Usando bibliotecas de terceiros Existem diversas bibliotecas de terceiros que podem te ajudar a gerenciar desinscrições de forma mais fácil. Uma biblioteca popular é o `ngx-unsubscribe`. ## Desinscrição automática com bibliotecas nativas do Angular Algumas bibliotecas nativas do Angular já fazem a desinscrição automaticamente. É o caso do `HttpClientModule` e do `Router`. Isso significa que você não precisa se preocupar em se desinscrever das solicitações HTTP ou das alterações de rota. ### HttpClientModule O `HttpClientModule` desinscreve automaticamente das solicitações HTTP quando a requisição é concluída ou quando o componente que fez a requisição é destruído. ### Router O `Router` desinscreve automaticamente das alterações de rota quando a navegação é concluída ou quando o componente que está escutando as alterações de rota é destruído. ### O async Pipe O `async` pipe é uma maneira conveniente de lidar com observables no template do Angular. Ele automaticamente se inscreve no observable e se desinscreve quando o componente é destruído. Isso ajuda a evitar vazamentos de memória sem precisar escrever código de desinscrição manual. #### Exemplo de uso do `async` pipe: ```html <div *ngIf="authService.isLoggedIn$ | async as isLoggedIn"> <p *ngIf="isLoggedIn">Você está logado!</p> <p *ngIf="!isLoggedIn">Você não está logado.</p> </div> ``` Neste exemplo, `isLoggedIn$` é um observable exposto pelo serviço `AuthService`. O `async` pipe se inscreve nesse observable e atualiza automaticamente o template com base no seu valor atual. ## E os observables do Reactive Forms? No caso dos observables do Reactive Forms, a desinscrição geralmente não é necessária. Isso porque esses observables são gerenciados internamente pelo Angular e são desinscritos automaticamente quando o componente é destruído. ## Exemplo Prático: Usando `valueChanges` e Desinscrição em um Componente de Login Vamos ver um exemplo prático de como usar a desinscrição em um componente de login simples. No nosso exemplo, vamos usar o operador `takeUntil` para nos desinscrever quando o componente for destruído e também monitorar as mudanças de valor dos campos de entrada. ```typescript import { Component, OnInit, OnDestroy } from '@angular/core'; import { FormGroup, FormControl, Validators } from '@angular/forms'; import { AuthService } from '../auth.service'; import { Subject } from 'rxjs'; import { takeUntil } from 'rxjs/operators'; import { Router } from '@angular/router'; @Component({ selector: 'app-login', templateUrl: './login.component.html', styleUrls: ['./login.component.css'] }) export class LoginComponent implements OnInit, OnDestroy { loginForm: FormGroup; private unsubscribeSubject = new Subject<void>(); constructor(private authService: AuthService, private router: Router) { } ngOnInit(): void { this.loginForm = new FormGroup({ email: new FormControl('', [Validators.required, Validators.email]), password: new FormControl('', [Validators.required]) }); // Monitorar mudanças de valor usando valueChanges this.loginForm.valueChanges .pipe(takeUntil(this.unsubscribeSubject)) .subscribe(changes => { console.log('Form value changed:', changes); }); } ngOnDestroy(): void { this.unsubscribeSubject.next(); this.unsubscribeSubject.complete(); } onSubmit(): void { const { email, password } = this.loginForm.value; this.authService.login(email, password) .pipe( takeUntil(this.unsubscribeSubject) // Desinscreve quando o unsubscribeSubject for emitido ) .subscribe( () => { // Login efetuado com sucesso this.router.navigate(['/']); }, (error) => { // Erro no login console.error(error); } ); } } ``` Neste exemplo, além de usar o operador `takeUntil` para desinscrever-se do observable de login quando o componente for destruído, também monitoramos as mudanças de valor do formulário usando `valueChanges`. Isso garante que as mudanças de valor sejam registradas enquanto o componente está ativo e paradas quando o componente é destruído. ## Resumo Neste artigo, vimos que as desinscrições são cruciais para evitar vazamentos de memória e garantir que seu aplicativo Angular funcione de forma eficiente. Abordamos os seguintes tópicos: 1. **O que é desinscrição e por que é importante?** 2. **Quando me desinscrever?** 3. **Como me desinscrever?** 4. **Desinscrição automática com bibliotecas nativas do Angular** 5. **O `async` Pipe** 6. **E os observables do Reactive Forms?** 7. **Exemplo prático: Usando `valueChanges` e Desinscrição em um Componente de Login** Espero que este artigo tenha te ajudado a entender melhor o conceito de desinscrições no Angular e como aplicá-lo em seus projetos. ### Dicas Extras: - Sempre que você criar uma inscrição em um observable, pense em como você vai se desinscrever dela. - Utilize ferramentas como o Angular DevTools para inspecionar as inscrições em seus componentes e identificar possíveis vazamentos de memória. - Adote bibliotecas de terceiros como o `ngx-unsubscribe` para facilitar o gerenciamento de desinscrições em seus projetos. Lembre-se: desinscrever-se é uma prática essencial para o desenvolvimento de aplicativos Angular robustos e eficientes.

Businesses are starting to use cloud technology in today's dynamic environment in order to remain ahead of the curve and spur growth. This is because these solutions are a great option for companies trying to survive in the competitive market since they provide a high degree of security, scalability, and cost savings. We'll look at why [enterprise cloud solutions](https://hatchtechs.com/it-solutions/cloud-development) are essential for company expansion and how they may completely change the way businesses operate in this blog post. **1. Scalability and Adaptability** Scalability is one of the key features of business cloud systems. For small firms, conventional IT solutions can be a significant obstacle because they often need large investments and time to scale up or down. Conversely, cloud solutions enable businesses to quickly and easily adapt their resources to the changing needs of the market. This flexibility ensures that companies won't have downtime or performance problems while responding to shifting consumer needs, seasonal variations, or unplanned development surges. **2. Improved Data Security** Within the digital era, data security may be a major ordeal for businesses. Secure components are integrated into cloud solutions to safeguard private data from cyber threats. High-end security measures like firewalls, multi-factor verification, and encryption are significantly helped by cloud providers. **3. Disaster Recovery and Business Continuity** Business operations can be significantly affected by natural disasters, or other unexpected tragedies. A great option for business growth and disaster recovery is given by utilizing enterprise cloud solutions. Cloud service providers frequently give disaster recovery and data backup services, ensuring that imperative corporate information is ensured and can be rapidly reestablished in the case of an intrusion. This capacity helps companies manage operations and diminish downtime, which is basic for extension and client satisfaction. **4. Environmental Sustainability** As businesses ended up more eco-friendly, undertaking cloud solutions offered an economical alternative to customary IT solutions. Cloud data centers are planned to be energy-efficient and diminish carbon footprint. Businesses can demonstrate their commitment to environmental sustainability by migrating to the cloud. This could propel a company's reputation and attract environmentally conscious customers and partners. **5. Quicker Time to Market** In a competitive business landscape, speed is pivotal. Cloud solutions empower businesses to send modern applications, services, and products more rapidly than with conventional solutions. The agility provided by the cloud permits companies to respond to market demands and customer requirements quickly, giving them a competitive edge. This agility can be a critical figure in driving business growth. **6. Global Reach** For businesses looking to increase their reach, enterprise cloud solutions give the foundation required to facilitate global operations. Cloud platforms are accessible around the world, permitting companies to scale their services and penetrate new markets without the requirement for extensive physical infrastructure. This worldwide reach can open up new doors for growth and revenue. **Conclusion** Cloud solutions are not just technological trends; they are a key requirement for businesses aiming for growth and scalability. The adaptability, cost efficiency, improved collaboration, and enhanced security provided by cloud solutions make them irreplaceable tools for driving business growth. By adopting enterprise cloud solutions, companies can reach a high level of efficiency and growth and gain a competitive advantage, stand out from their competition, and thrive in the digital world.

Transforming Titans: A Novel Journey of Agile Leadership in Outsourcing

### **Chapter 1: The New Beginning** [Paul Keen](https://www.linkedin.com/in/paul-keen/) stood in his new office, his mind racing with possibilities and challenges. He had just been hired as the CTO of a company known for its outstaffing model, where they provided clients with skilled tech personnel. However, Paul's mission was clear: transform this company into a thriving outsourcing service provider. The CEO had been clear. The market was changing, and they needed to adapt. Clients wanted complete solutions, not just people. The task seemed daunting, but Paul was ready. He knew this journey would be challenging. There would be obstacles, and it would be tough without help. He thought of "The Phoenix Project," a book he once read about turning around a failing IT organization. It was time to channel that same energy. Paul's first step was to understand the company's current state. He called it "Operation Insight." This initial phase set the stage for a comprehensive transformation, where understanding the company's strengths and weaknesses would be crucial for the next steps. ### **Chapter 2: The First Steps**  Paul analyzed SWOT to identify strengths, weaknesses, opportunities, and threats. Strengths? The company had great talent. Weaknesses? They needed more processes for delivering complete projects. Opportunities? There is a vast market for outsourcing services. Threats? Competitors were already doing it. In addition to SWOT, Paul developed a detailed Stakeholder Mapping and Engagement Plan. This plan identified key stakeholders, their influence, and their concerns. Engaging these stakeholders early would often be critical to the success of the transformation. - **CEO Alina**: Strong supporter, emphasized the need for complete solutions to stay competitive. - **CFO Mark**: Cautious and concerned about the financial implications of the transformation. - **Head of Sales Dima**: Optimistic, saw potential for increased revenue and market share. - **HR Head Sarah**: Skeptical, worried about the impact on staff and the need for retraining. - **CMO Erik**: Enthusiastic and eager to leverage marketing to showcase the new services. - **The Board**: Mixed views, but generally supportive if financial stability could be maintained. Paul came up with a vision. The company needed to offer complete outsourcing solutions. They would handle entire projects, not just provide people. After forming a clear vision for complete outsourcing solutions, Paul knew the next critical step was to rally the whole company behind this transformation. He initiated town hall meetings to create a sense of urgency. Paul held town hall meetings to explain why the change was critical. He painted a vivid picture of a future where the company led the market in outsourcing services, instilling a sense of urgency and the need for immediate action in the audience. With the groundwork laid, Paul was ready to form a dedicated team to drive the transformation forward. ### **Chapter 3: The Vanguard**  Next, he formed a powerful coalition — The Vanguard. This team comprised critical stakeholders from different departments and was crucial to the transformation. Using the stakeholder map, Paul carefully selected members who could drive change and influence others. Some, like Michael Vas, a veteran project manager with extensive experience, were on board. His knowledge and insights were invaluable, and he quickly became Paul's trusted lieutenant. Michael suggested addressing Sarah's skepticism directly. "We need her on our side, Paul. Let's sit down with her and address her concerns." Paul agreed and arranged a meeting with Sarah. "Sarah, I understand your concerns about the impact on staff. Let's work together to ensure everyone is supported," Paul began. Sarah sighed, "It's just that this change is massive, and I'm worried about our employees' morale and their ability to adapt." "We can develop comprehensive training programs and provide continuous support," Paul assured her. "Your expertise in HR will be vital in this process." After a lengthy discussion, Sarah nodded, "Alright, I see the potential benefits. I'll help manage the staff transition and ensure we communicate effectively." Sarah's expertise in HR became a vital asset to the Vanguard, helping to manage staff transitions and morale. With her support, the team was better equipped to handle the challenges ahead. Erik, the CMO, also brought valuable insights. "We need to market these changes effectively to our clients. Let's ensure our messaging highlights the benefits of our new services," he said. The formation of the Vanguard marked the beginning of active efforts towards implementing the transformation strategy. ### **Chapter 4: The Trials and Tribulations**  Recognizing the need for quick wins to build momentum, Paul and his team launched pilot projects. These were carefully chosen to test their new processes and demonstrate early successes. One afternoon, Paul and Michael sat down to review the pilot project's results. "We're missing deadlines, and costs are ballooning," Paul noted, frustration evident in his voice. Michael nodded, "We need to be more agile. Let's incorporate Lean Startup principles – iterate quickly and learn from each step." "Agreed," Paul replied, "Let's test small and learn fast." They implemented these changes, and the next project saw marked improvements. The evolution of their projects was strategic. They started with the smallest pivot projects, ensuring quick feedback and minimal risk. Once they fine-tuned their processes, they moved on to one or two medium-sized projects. Success in these gave them the confidence to scale their operations, handling many small projects simultaneously before finally tackling a significant enterprise project. The road, however, was bumpy. Resistance came from unexpected quarters. The finance team, led by Robert, was a significant hurdle. Robert is stuck in old ways and questions every expense and new hire. In a tense meeting, Robert challenged the budget again. "Why do we need so many new hires?" he demanded. Paul remained calm. "Robert, these investments will pay off in the long run. We need to think about scalability." Michael backed him up, "We have data to support these decisions. Our projections show significant returns." Paul had to convince him that investing now would pay off later. This involved presenting detailed projections and demonstrating the long-term benefits of the new model. The challenges faced during these trials laid the groundwork for the following successes. ### **Chapter 5: Gaining momentum**  By the end of the first year, they were gaining momentum. The second round of pilot projects was smoother. They delivered on time and within budget. Clients were happy. Paul could see the vision coming to life. He knew they needed a solid technology foundation, so they adopted new tools like project management software, collaboration platforms, and automation tools. Security was a top priority, and they ensured compliance with industry standards. Training was critical. Michael and Sarah proposed launching an extensive training program using the ADKAR model: Awareness, Desire, Knowledge, Ability, and Reinforcement. Employees learned new skills and adapted to new roles. Michael emphasized in a meeting, "We need to stay ahead of the curve, or we'll be left behind." Sarah added, "Our people are our greatest asset. Investing in their growth is investing in our future." Paul nodded, appreciating their initiative, "Let's make sure the training program is comprehensive and ongoing." With a solid foundation and a motivated team, they were ready to tackle larger challenges and scale their operations. ### **Chapter 6: The Turning Point**  Year two was pivotal. They were ready to scale. The Vanguard worked tirelessly. They expanded their service offerings. More clients signed up for complete outsourcing solutions. The company rebranded itself as an outsourcing leader. Paul's vision was becoming a reality. They held brainstorming sessions to innovate. Ideas flowed, and creativity soared. They used Design Thinking to solve complex problems. In one such session, Michael suggested involving clients more directly. "Their input can guide us to tailor solutions perfectly," he said. This client-centric approach boosted satisfaction and loyalty. Paul shared yearly reports of progress and performance, ensuring everyone was informed and involved and building trust and transparency. He learned to navigate the corporate landscape, balancing different interests. The board was happy with the progress but still had concerns about the plans for the next two years and potential risks. "We need to ensure our strategies are robust enough to handle unforeseen challenges," one board member remarked during a review meeting. ### **Chapter 7: Overcoming Setbacks**  While some things went smoothly, a significant project encountered a problem. Deadlines were missed, and costs exceeded the budget. As a result, the client went mad. Nonetheless, the Vanguard acted quickly and decisively. They organized a crisis meeting and used the '5 Whys' technique to identify the root causes of the issues. After addressing the problems, they reassured the client, demonstrating their commitment to the project and their ability to handle challenges effectively. Paul was particularly impressed with Sarah's performance during this crisis. Her leadership and dedication to managing staff morale and transitions were exceptional. This challenging experience strengthened their determination and inspired them to persevere, showcasing their resilience to the audience. ### **Chapter 8: The Final Stretch**  By the third year, they were a well-oiled machine. The company had transformed. They delivered projects seamlessly, delighted clients, and stayed ahead of the competition. They were a market leader in outsourcing services. Paul's journey had been challenging. There were mistakes and setbacks but also victories and lessons learned. The Vanguard was not just a team but a close-knit unit that stood together in the face of change. Michael Vas was not just a colleague but his trusted lieutenant. Sarah's contributions were equally invaluable; her leadership in managing staff and morale played a crucial role. Together, they had turned the vision into reality, showcasing the power of unity in driving change. The board and CEO Alina reviewed the results and expressed their appreciation. "You've achieved 87% of our ambitious goals, which is outstanding," Alina remarked. "We've uncovered many new potentials and opportunities, surpassing our expectations." They celebrated their success, but Paul knew the journey wasn't over. They had to keep innovating and adapting, always striving for better. This commitment to progress was a crucial part of their success and a testament to their dedication to excellence. ### **Chapter 9: The Lessons Learned**  Paul gathered the entire Vanguard team for a final reflection on their journey. He began, "We've come a long way from where we started. What have we learned?" Michael was the first to speak, "Agility is crucial. Lean Startup principles kept us on track." Sarah added, "Investing in our people has paid off. The ADKAR model was instrumental." Paul nodded, "Exactly. Kotter's 8-Step Change Model provided structure, while Design Thinking fueled our innovation." Erik said, "Marketing the transformation effectively was key to gaining client trust." "Absolutely," Paul agreed, "And Kaizen kept us agile. Our tools and frameworks were essential, but our people made it happen." "Teamwork and clear communication were our biggest assets," Dima commented, reinforcing the sense of unity. Paul concluded, "Let's carry these lessons forward. The market will keep evolving, but with our vision and dedication, we're ready for any challenge." The team exchanged nods and smiles, feeling a deep sense of accomplishment and readiness for the future. ### **Chapter 10: The Future**  Paul looked ahead. The company was strong, but it couldn't rest on its laurels. The market would keep evolving. It had to stay ahead and keep delivering value. He knew it could do it. It had the vision, the team, and the tools. Paul smiled. The journey had been worth it. They had transformed, but the adventure was just beginning. They were ready for whatever came next. ### **References** - **Kotter’s 8-Step Change Model**: [Read More](https://www.kotterinc.com/8-step-process-for-leading-change/) - **Lean Startup**: [Read More](https://leanstartup.co/) - **PDCA Cycle**: [Read More](https://asq.org/quality-resources/pdca-cycle) - **SWOT Analysis**: [Read More](https://www.mindtools.com/pages/article/newTMC_05.htm) - **ADKAR Model**: [Read More](https://www.prosci.com/methodology/adkar) - **Stakeholder Mapping**: [Read More](https://www.mindtools.com/pages/article/newPPM_07.htm) - **Impact Mapping**: [Read More](https://www.impactmapping.org/) - **Design Thinking**: [Read More](https://www.ideou.com/pages/design-thinking) - **Kaizen**: [Read More](https://www.kaizen.com/what-is-kaizen.html) This was Paul Keen's story.
