🚀 Excited to share my first React open-source library "react-dnd-provider" https://lnkd.in/gF6ztipE is now live on npm! 🚀 🚫 No external library used, ✅ written purely in typescript and React. After navigating through build configs, npm publishing hurdles and lots of debugging, I’ve successfully published react-dnd-provider 🎉 This project involved designing a clean drag-and-drop API, building a reusable React library, handling modern build tooling, and publishing it for public use with full JavaScript and TypeScript support. 🔧 What you can build with it: Kanban boards Sortable lists Multi-column drag & drop layouts Custom drag-and-drop UIs with full styling control ✨ Key highlights: Simple, clean API Works with React JS & React TS Unstyled by default → full design freedom Controlled onDragEnd pattern 📦 npm: react-dnd-provider 📘 Documentation: https://lnkd.in/ggpc8yRQ Building this reinforced practical skills in React internals, API design, and production-ready packaging. Open to feedback and collaboration. 👉 I’d love for you to try it out, give feedback, or contribute! ⭐ If you find it useful, a star on GitHub would mean a lot. #opensource #react #javascript #typescript #webdevelopment #npm #frontend #learninginpublic #developer

Old is gold? Understanding Class Components in React. 🏛️⚛️ While Functional Components and Hooks are the modern standard, Class Components are still the backbone of many legacy codebases. Mastering them is key to being a well-rounded React developer. What’s inside? ✅ The Structure: Extending React.Component to create your class. ✅ State Management: How to use the constructor and this.state to store data. ✅ Event Handling: Updating state dynamically using methods like incrementCount. ✅ The Render Method: Returning JSX to describe the UI. ✅ Lifecycle Methods: Hooking into component stages (Mounting, Updating, Unmounting). ✅ Reusability: Building modular codebases with component composition.

Is Bun the ultimate productivity hack for JS developers? ⚡ I just came across this breakdown of the Bun JavaScript Runtime, and it’s a game-changer for anyone tired of "tooling fatigue." Imagine having your runtime, bundler, transpiler, and package manager all in one place. 𝐊𝐞𝐲 𝐭𝐚𝐤𝐞𝐚𝐰𝐚𝐲𝐬 𝐭𝐡𝐚𝐭 𝐜𝐚𝐮𝐠𝐡𝐭 𝐦𝐲 𝐞𝐲𝐞: • 𝐄𝐧𝐠𝐢𝐧𝐞 𝐏𝐨𝐰𝐞𝐫: Unlike Node.js or Deno, Bun uses JavaScriptCore—the engine that powers Safari—to achieve incredible speed. • 𝐒𝐢𝐦𝐩𝐥𝐢𝐜𝐢𝐭𝐲: It’s an all-in-one toolkit, meaning fewer tools to install and a much simpler workflow. • 𝐍𝐏𝐌 𝐂𝐨𝐦𝐩𝐚𝐭𝐢𝐛𝐢𝐥𝐢𝐭𝐲: You can still use your favorite packages like Axios, but manage them faster with bun add. • 𝐍𝐚𝐭𝐢𝐯𝐞 𝐓𝐲𝐩𝐞𝐒𝐜𝐫𝐢𝐩𝐭 𝐒𝐮𝐩𝐩𝐨𝐫𝐭: You can run .ts files directly without extra configuration. If you're looking to speed up your development cycle, Bun is definitely worth a look. Have you made the switch from Node.js yet, or are you still on the fence?

Day 29/30 — "Learning React JS From Scratch 🚀" Today I learned how to optimize performance in React applications using Debouncing and Throttling — two powerful techniques to control how often a function executes. ✅ Debouncing Runs a function only after the user stops performing an action. Perfect for search inputs, form validation, and autosave features. ✔ Reduces unnecessary API calls ✔ Improves performance ✔ Saves server load ✅ Throttling Runs a function at fixed time intervals, even if the event happens many times. Ideal for scroll events, resize handlers, and mouse movements. ✔ Controls event frequency ✔ Keeps UI smooth ✔ Prevents browser overload 🎯 Key takeaway: Debouncing waits for the action to stop. Throttling limits how often the action runs. These techniques help build faster, more efficient, and scalable React applications. #ReactJS #JavaScript #WebDevelopment #FrontendDevelopment #PerformanceOptimization #LearningInPublic #DeveloperJourney #Programming #TechLearning #Trending #Growth #Consistency #BuildinPublic

A Clean React.js Folder Structure = Cleaner Code & Smoother Development. Every React project becomes easier to scale when your folders are organized from day one. Clear structure means fewer bugs, faster debugging, and more time to focus on building real features. This cheatsheet breaks down how you can structure components, hooks, pages, services, assets, and utils in a way that keeps your project tidy and future-proof.

⚛️ React Hooks.. Hooks make React functional components powerful, reusable, and easy to manage. Here’s a quick list of the most important ones: Basic Hooks: useState – manage state useEffect – handle side effects useContext – access global state Additional Hooks: useReducer – complex state logic useCallback – memoize functions useMemo – memoize values useRef – access DOM & persist values useImperativeHandle – expose methods from child useLayoutEffect – run effects before browser paints useDebugValue – debug custom hooks Combine these hooks to write clean, reusable, and high-performance React code. #ReactJS #WebDevelopment #FrontendDeveloper #CodingTips #Hooks #JavaScript Mentor: Miss Sheikh Hafsa Nadeem
