But have you ever wondered how JavaScript performs so well with asynchronous operations? The credit goes to Libuv for making asynchronous I/O so seamless! Libuv is the powerhouse behind the scenes, handling tasks like file reading, API calls, timers, and promises. It does this by interacting directly with the server or system's OS. But how does it hand these tasks back to the JavaScript engine? Enter our mini-superhero: the event loop (or "I/O loop"). The event loop continuously checks if the JS engine is busy and if there are any ready-to-go callback functions in one of its many callback queues. This loop operates in phases: 𝗧𝗶𝗺𝗲𝗿 𝗣𝗵𝗮𝘀𝗲 – 𝗘𝘅𝗲𝗰𝘂𝘁𝗲𝘀 𝘁𝗶𝗺𝗲𝗿𝘀 𝗹𝗶𝗸𝗲 𝘀𝗲𝘁𝗧𝗶𝗺𝗲𝗼𝘂𝘁. 𝗣𝗼𝗹𝗹 𝗣𝗵𝗮𝘀𝗲 – 𝗧𝗵𝗲 𝗺𝗼𝘀𝘁 𝗰𝗿𝘂𝗰𝗶𝗮𝗹 𝗽𝗵𝗮𝘀𝗲, 𝘄𝗵𝗲𝗿𝗲 𝗮𝗹𝗹 𝗜/𝗢 𝗼𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝘀 𝗮𝗿𝗲 𝗵𝗮𝗻𝗱𝗹𝗲𝗱. 𝗖𝗵𝗲𝗰𝗸 𝗣𝗵𝗮𝘀𝗲 – 𝗘𝘅𝗲𝗰𝘂𝘁𝗲𝘀 𝘀𝗲𝘁𝗜𝗺𝗺𝗲𝗱𝗶𝗮𝘁𝗲 𝗰𝗮𝗹𝗹𝗯𝗮𝗰𝗸𝘀. 𝗖𝗹𝗼𝘀𝗲 𝗣𝗵𝗮𝘀𝗲 – 𝗧𝗮𝗸𝗲𝘀 𝗰𝗮𝗿𝗲 𝗼𝗳 𝗰𝗹𝗲𝗮𝗻𝘂𝗽 𝗽𝗿𝗼𝗰𝗲𝘀𝘀𝗲𝘀 But that’s not all it does! It even processes process.nextTick() and promise resolutions before each phase. The loop keeps on ticking until there are no more processes to handle, then it halts at the poll phase. Wait, there's more! Libuv also comes with a thread pool. By default, it has four threads or processes, allowing us to handle four asynchronous tasks concurrently. Need more power? You can customize the number of threads to suit your server’s requirements by setting: 𝗽𝗿𝗼𝗰𝗲𝘀𝘀.𝗲𝗻𝘃.𝗨𝗩_𝗧𝗛𝗥𝗘𝗔𝗗_𝗣𝗢𝗢𝗟_𝗦𝗜𝗭𝗘 = 𝟭𝟬; So, here's a question for you- 𝙄𝙨 𝙉𝙤𝙙𝙚.𝙟𝙨 𝙨𝙞𝙣𝙜𝙡𝙚-𝙩𝙝𝙧𝙚𝙖𝙙𝙚𝙙 𝙤𝙧 𝙢𝙪𝙡𝙩𝙞-𝙩𝙝𝙧𝙚𝙖𝙙𝙚𝙙 ? 𝙎𝙝𝙖𝙧𝙚 𝙮𝙤𝙪𝙧 𝙩𝙝𝙤𝙪𝙜𝙝𝙩𝙨 𝙞𝙣 𝙩𝙝𝙚 𝙘𝙤𝙢𝙢𝙚𝙣𝙩𝙨 𝙗𝙚𝙡𝙤𝙬! Isn’t it fascinating? We often think writing high-level JavaScript is challenging, but just look at how intricate and beautifully abstracted Node.js is, thanks to Libuv. And here’s the best part: Libuv is open-source! If you're curious to dive deeper, you can explore the implementation in C. Interested? Check out the source code and documentation through the link below:

🌟 Unraveling the Power of Node Package Manager (npm) 📦💡 Hey there, fellow developers! Today, let's explore the wonders of npm, a key tool in any Node.js developer's arsenal. Whether you're new to Node.js or an experienced pro, mastering npm can significantly streamline your development process. Here's why npm is a game-changer: 1️⃣ What is npm?: npm stands for Node Package Manager. It's the largest software registry in the world, containing over a million code packages. From small utilities to large-scale frameworks, npm has it all. 2️⃣ Easy Package Management: With npm, installing, updating, and managing Node.js packages is a breeze. It handles dependencies efficiently, ensuring that your projects have exactly what they need to run smoothly. 3️⃣ Creating Your Package: npm isn't just for using packages; it's also for creating them. Share your code with the world by packaging your modules and publishing them on the npm registry. 4️⃣ Version Control: npm helps manage package versions, ensuring compatibility and stability in your projects. Learn about semantic versioning to keep your projects error-free. 5️⃣ npm Scripts: Automate repetitive tasks with npm scripts. These are customizable and can be used for testing, building, and deploying your applications. 6️⃣ Security: npm includes features to help you identify and fix vulnerabilities in packages, keeping your projects secure. 7️⃣ npm vs. Yarn: While npm is the default package manager for Node.js, Yarn is another popular choice. Compare their features and performance to see what works best for your projects. 🔗 Tip: Consistently update npm to its latest version to enjoy improved performance, better security, and new features. 🌐 #npmMagic #NodeJs #WebDevelopment #JavaScript #DevTools #CodingLife Let's discuss! Share your favorite npm packages or tips in the comments. If you're just starting with npm, feel free to ask questions. Happy coding!

好久沒來寫筆記了 如何使用 GitHub Actions 將 React TypeScript 項目部署到 GitHub Pages https://lnkd.in/gfJDNE4Z How to Deploy a React TypeScript Project to GitHub Pages using GitHub Actions https://lnkd.in/gVrcirkr #devops #React #Typescript #GitHub

In this tutorial, you will learn how to upgrade and refactor your React application to the latest version without having to rewrite any code using react-codemod. https://lnkd.in/dU5kSZWc

In Node.js projects managed by npm (Node Package Manager), there are two main categories of dependencies defined in the package.json file: "dependencies" and "devDependencies". Here's the difference between them: 1. Dependencies:   - Dependencies listed under the "dependencies" key in the package.json file are packages required for the application to run in production.   - These packages are essential for the functionality of the application itself when it's deployed or used by end-users.   - Examples of dependencies include libraries for server-side frameworks, utility libraries, database drivers, etc.   - When you run npm install or npm install <package>, npm will install both the dependencies and their transitive dependencies required for the application to run in production. 2. DevDependencies:   - DevDependencies listed under the "devDependencies" key in the package.json file are packages required for development and testing purposes.   - These packages are not necessary for the application to run in production, but they are essential for development workflows such as testing, building, linting, etc.   - Examples of devDependencies include testing frameworks (like Mocha or Jest), build tools (like Webpack or Parcel), code linters (like ESLint), etc.   - DevDependencies are typically installed by running npm install --save-dev <package> or by directly adding them to the "devDependencies" section in the package.json file.   - When you run npm install --production, npm will only install dependencies listed under "dependencies" and skip installing devDependencies, making the installed package lighter for production use. In summary, dependencies are packages required for the application to run, while devDependencies are packages required for development and testing workflows. Separating them allows for better management of project dependencies and ensures that unnecessary packages are not included in production deployments. #FrontendDeveloper #ReactJS #FrontendDevelopment #ReactDeveloper #JavaScript #WebDevelopment #FrontendEngineering #UIDevelopment #ReactNative #FrontendDesign #ReactComponents #FrontendFrameworks #ReactHooks #WebDesign #FrontendArchitecture #NPM #node
