React SDK v5: responsive images, lazy loading, TypeScript support

1. Master React fundamentals – Next.js builds on React. Know hooks, context, and component lifecycle. 2. Understand file-based routing – Learn dynamic routes, nested routes, and app vs pages directory. 3. Learn server components – Grasp how and when to use server vs client components for performance. 4. Practice API routes – Build simple backend logic inside /api to understand full-stack workflows. 5. Work with data fetching – Use getStaticProps, getServerSideProps, and fetch in server components. 6. Optimize for performance – Apply image optimization, lazy loading, and caching. 7. Deploy often – Use Vercel for fast feedback and understand deployment flow. 8. Explore authentication – Try next-auth for session management. 9. Use TypeScript – Improves code quality and scales better. 10. Study real projects – Read open-source Next.js repositories to learn best practices.

🚀 Exploring Node.js Node.js lets you run JavaScript on the server side—so you can build entire applications with a single language from frontend to backend. ✨ Why it stands out Fast & scalable: Non-blocking, event-driven architecture handles many requests at once. One language everywhere: Write both client and server code in JavaScript. Huge ecosystem: npm offers thousands of ready-to-use packages. Whether you’re creating APIs, real-time apps, or microservices, Node.js makes development smooth and efficient. Have you tried Node.js in a recent project?

My first production app took 30 seconds to load on 3G 😅 All because of a 2.5MB JavaScript bundle. The culprit? I'd imported entire libraries when I only needed one function. Classic mistake. After optimizing bundle size, that same app now loads in under 3 seconds. Here's what actually moved the needle. The bundle bloat checklist I use now: Before adding any library, I ask three questions: - How big is it? (bundlephobia.com) - Can I build this with vanilla JS instead? - Is there a lighter alternative? Small example with huge impact: I replaced moment.js (67kB) with date-fns (13kB), then realized I only needed 2 functions. Switched to native Intl.DateTimeFormat. That's 0kB. The entire moment.js library was unnecessary bloat. The game-changer for me was code splitting. Instead of shipping all your code upfront, lazy load the heavy stuff: const AdminDashboard = React.lazy(() => import('./AdminDashboard')); function App() { return ( <Suspense fallback={<LoadingSpinner />}> <AdminDashboard /> </Suspense> ); } Users only download admin dashboard code when they actually navigate there. My initial bundle dropped from 2.5MB to 400kB just with lazy loading. My production bundle checklist: - Production mode builds (Vite/Webpack optimize automatically) - Tree-shaking enabled - Routes and heavy components lazy loaded - Images optimized (WebP, lazy loading) - Bundle analyzed with webpack-bundle-analyzer Target: <300kB initial JavaScript for most apps. The result? Faster first paint, happier users, better Core Web Vitals. Every kilobyte matters, especially on slower connections. 👉 What's the biggest bundle killer you've found in your apps? Would love to hear what optimization surprised you the most. #WebPerformance #FrontendOptimization #React #Performance

You know that moment when you're debugging a JavaScript app late at night, chasing a type error that's crashing everything? Yeah, I've been there alottt of times. Last year, on a team project, we were building this complex system and loose typing was causing chaos. Switching to TypeScript turned it around, I caught bugs at compile time, made the code readable and sped up our workflow alot. What Makes TypeScript a Must-Have: It's like adding guardrails to JavaScript. Interfaces and generics let you define clear contracts between frontend and backend, so when I'm hooking up a React UI to a Node.js server, everything just clicks 😉

🚀 Fast React Development with Vite! Looking to speed up your React projects? Vite is a modern build tool that gives you blazing-fast hot module replacement and minimal setup. Create a Vite Project: 1️⃣ Initialize the project: npm create vite@latest Choose project name → framework (React) → variant (JS/TS) 2️⃣ Move into the folder & install dependencies: cd my-vite-app npm install 3️⃣ Start the dev server: npm run dev Your app runs at http://localhost:5173 🌐 Creating Components: Create a folder: src/components/ Example component Greeting.jsx: function Greeting() { return <h2>Hello from Greeting Component 👋</h2>; } export default Greeting; Import it in App.jsx: import Greeting from './components/Greeting'; <Greeting /> Key Commands Recap: npm create vite@latest → New Vite project npm install → Install dependencies npm run dev → Run server 💡 Pro Tip: Vite + React lets you build modular, fast, and reactive applications effortlessly.

Sharing another one of my recent projects: a React Password Generator. 🔒 This project was a deep dive into core React concepts, focusing on managing complex state and optimizing application performance. Key hooks implemented: • Advanced state logic with useState and useEffect • Performance optimization using useCallback • Direct DOM interaction with useRef for the copy-to-clipboard feature Live Demo: https://lnkd.in/grK-qeCZ GitHub Repo: https://lnkd.in/gWAFjdu9 #ReactHooks #ReactJS #Frontend #Developer #JavaScript #Portfolio

🚀 Getting Started with TypeScript + React (Made Simple) If you’re new to TypeScript in React, don’t panic — it’s just JavaScript with extra safety. Here’s a quick starter: 🔑 Why use TypeScript in React? Catch errors early (before running the app). Better IntelliSense in VS Code. Self-documenting code (others know what data you expect). 💡 Have you started using TypeScript with React yet, or are you still on plain JS? #TypeScript #ReactJS #WebDevelopment #FrontendEngineering #CodingTips

🚀 Master React Hooks in 2025! Whether you're a beginner or a pro, understanding how hooks truly work is what separates clean, scalable React apps from messy ones. This carousel covers all essential hooks — with ✅ Do’s, ❌ Don’ts, 💡 Pro Tips, and code examples to help you write smarter React code. 👉 Save this post for future reference and follow for more modern React tips. #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #Hooks#Coding

You don't always need frameworks. In recent times, when you ask a developer to build any application, even the simple Ol' todo app, they immediately setup a framework to build with. It's surprising that some developers using frameworks like React, Vue, Nextjs, Angular, and the likes can not build an application with vanilla JavaScript, HTML and CSS. You might say it doesn't mean anything. After all you get gigs/jobs and you get paid using these frameworks. But it truly means a lot. Knowing the fundamentals makes you better. But you know what? Do what makes you comfortable 😀

🚀 React Quiz App — Test Your JavaScript Knowledge! I’ve just built a fully functional Quiz Application using React to test JavaScript fundamentals 💻. This project was an amazing practice for mastering React Hooks and the component-based architecture. 🧠 Main Features: Dynamic questions fetched from a local JSON server (activated via the package.json script). Used useReducer for managing complex state logic efficiently. Implemented useEffect to handle data fetching and side effects. Used props to pass data cleanly between components. Includes a countdown timer ⏳ — when time runs out, the quiz automatically ends! Interactive UI with Next Question navigation and real-time progress tracking. This project helped me strengthen my understanding of React state management, component reusability, and data fetching — while keeping the app responsive and user-friendly.
