package-lock.json Ensures Predictable Builds

Behind the Screen – #34 Do you know? The #node_modules folder is often larger than your entire project. Why is it so big? 👉 Your project depends on many #packages   👉 Each package has its own #dependencies   👉 Those dependencies have their own dependencies  This creates a dependency tree. So when you #install one library, you might actually be installing hundreds of smaller packages. Also: 👉 Packages include multiple files (code, configs, docs)   👉 Different versions may coexist   👉 Everything is stored #locally for faster usage  That’s why node_modules grows so quickly. It may look heavy, but it helps your app run without fetching things again and again. 🔥 One install command can bring an entire ecosystem into your project. #javascript #reactjs #webdevelopment #techfacts #developer

Built a simple CRUD app using React Worked on a project where users can: Create posts (with image, title, description) View all posts in card format Edit posts without creating duplicates Delete posts instantly Learned: 1.State management with useState 2.Handling forms & file inputs 3.Conditional rendering 4.Updating vs creating data (real CRUD logic) 5.Simple project, but helped me understand React much better. #React #JavaScript #WebDevelopment #CRUD #LearningInPublic

I kept wondering why my React app was calling the same API multiple times… 🤯 At first, I thought it was a small issue. But as the project grew, it became a real problem: * Repeated API calls * Too much state handling (loading, error, data) * Debugging became painful All because I was using `useEffect` for API calls. Then I tried something different — **React Query**. And honestly, it changed the way I handle server data: ✅ Automatic caching ✅ Built-in loading & error handling ✅ Cleaner, more maintainable code The biggest realization for me: 👉 *useEffect is not meant for managing server state.* I wrote a short article sharing what I learned and how I fixed these issues in a real project 👇 🔗 https://lnkd.in/gPMTcQBw If you're working with React, this might save you some debugging time. Would love to hear how you're handling API calls in your apps 👇 #React #JavaScript #PerformanceOptimization #WebDevelopment #ReactQuery

My React app was freezing the browser completely. Chrome tab: "Page Unresponsive" 😱 After 2 hours of debugging I found this: const UserProfile = () => { const [user, setUser] = useState({}) // ❌ New object created every render // triggers useEffect infinitely! useEffect(() => { fetchUser().then(data => { setUser(data) }) }, [user]) // 👈 THIS is the problem return <div>{user.name}</div> } Can you spot the bug? 👇 The problem: 1. Component renders 2. useEffect runs → setUser({...}) 3. user state changes → re-render 4. useEffect runs again → setUser({...}) 5. Repeat forever 💀 The fix: const UserProfile = () => { const [user, setUser] = useState({}) // ✅ Empty array = run only once useEffect(() => { fetchUser().then(data => { setUser(data) }) }, []) // 👈 Fixed! return <div>{user.name}</div> } 3 rules to avoid infinite re-renders: → Never put state in useEffect deps if you're setting that same state inside → Empty [] = run once on mount → Always ask: "Does this dep actually need to be here?" 2 hours of debugging. 1 character fix. 😅 Have you hit this bug before?

I inherited a slow React app with 8 second load times. High bounce rate. Frustrated client. Zero documentation. Here's exactly how I fixed it — step by step 👇 The 4 problems killing performance: → No Server Side Rendering → Unoptimized images loaded all at once → No code splitting — full bundle on every page → Zero caching strategy The fix? 4 targeted changes: ✅ Migrated to Next.js SSR ✅ Switched to next/image with WebP format ✅ Added dynamic imports & code splitting ✅ Implemented CDN caching at the edge The results: → Page load: 8s → 3.2s → Bounce rate: dropped → User retention: climbed → Client: renewed the contract Performance isn't a feature. It's the foundation everything else is built on.

Most developers never measure the thing they do every single day: typing accuracy under pressure. I built a React web app that tracks typing speed and accuracy in real time — not because WPM is the goal, but because precision matters when you're live-coding, pair programming, or reviewing code on a deadline. Tech highlights: • Real-time keystroke tracking using React state and event handlers • Accuracy scoring that separates speed from correctness • Deployed across Vercel, Netlify, and Firebase with automated CI/CD • Security scanning in the pipeline — because even small tools deserve hardening Building this taught me more about React's event loop than most tutorials ever did. The difference between debounced and immediate key capture completely changes how an app feels to use. What's your WPM? And do you think raw typing speed actually affects coding productivity? #React #JavaScript #WebDevelopment #Frontend #OpenSource

🚀 React Portfolio Series – Project #14 This Dashboard Login template is a project I built to simulate a complete authentication system in a real-world application environment. Even though the authentication is “fake”, the experience is designed to feel fully authentic — from login flow to profile management and protected routes. From a technical standpoint, this project helped me strengthen: • Building a full authentication flow using local storage, cookies and Zustand • Creating protected routes and handling user sessions in a Next.js app • Implementing full CRUD operations (create, read, update, delete) for profile data • Writing and testing forms with Jest • Professional form handling using useReducer and after-submit validation (errors appear only after user interaction) The app includes both Guest Mode and Profile Mode, allowing flexible interaction similar to a real product. More projects coming daily — I’ll share 20+ React builds from my portfolio. 🔗 Live demo: https://lnkd.in/dY3BAH8b 🔗 Github: https://lnkd.in/dc2xTNHy #react #nextjs #typescript #tailwindcss #frontend #webdevelopment #dashboard

Most React apps have a performance killer hiding in plain sight. It's unnecessary re-renders. Here's how to stop them: 1️⃣ Use React.memo() for pure components   → Skips re-render if props haven't changed 2️⃣ useMemo() for expensive calculations   → Only recalculates when dependencies change 3️⃣ useCallback() for function props   → Prevents child re-renders caused by new function references 4️⃣ Lift state only where needed   → Don't store everything in a top-level component 5️⃣ Use React DevTools Profiler   → Visualize exactly what's re-rendering and why Bonus: The React Compiler (coming to React 19) will handle much of this automatically. But understanding the problem still makes you a better engineer. Save this for your next performance audit. 🔖 #React #ReactJS #JavaScript #WebPerformance #Frontend
