Upgrade from useEffect to TanStack React Query

Optimizing Next.js Performance with Smart Imports Understanding the difference between static and dynamic imports is key to building fast, scalable Next.js applications. 🔹 Static Import – Component is included in the bundle on every page load: import MyComponent from './MyComponent'; 🔹 Dynamic Import – Component loads only when required: import dynamic from 'next/dynamic'; const MyComponent = dynamic(() => import('./MyComponent'), { ssr: false, // disable server-side rendering if not needed }); 💡 Tip: For heavy or infrequently used components, dynamic imports reduce initial bundle size and improve overall application performance. #NextJS #ReactJS #WebDevelopment #Frontend #CodeOptimization #Performance #DeveloperTips

Next.js 16 changed how I think about rendering strategy. Cache Components + stable Turbopack means we can design faster pages without overcomplicating data boundaries. If you're still on older versions, this is a good cycle to plan a clean migration. What part of your Next.js stack would you modernize first? #nextjs #reactjs #webdevelopment #fullstack #frontend

Hot take 👀 Most performance issues in React apps are not because of React… They come from: • unnecessary re-renders • over-fetching data • poor caching decisions • and using useMemo / useCallback everywhere without understanding why 😅 Tools don’t make apps fast. Architecture does. Still learning this the hard way 🚀 #WebDevelopment #ReactJS #Frontend

We’ve started planning our upgrade journey from Next.js 14.2 to 16.x — taking a careful, step-by-step approach for our products, - Evaluating breaking changes across versions - Mapping upgrade path: 14.x → 15 → 16.x - Reviewing middleware, caching, and API updates - Preparing for React 19 & Node 20 compatibility (Very Important as most of the products are still on Node 18.x) Stay tuned as we move from planning → execution. #NextJS #ReactJS #WebDevelopment #Frontend #JavaScript #TechPlanning #UpgradeJourney #SoftwareEngineering #Developers #Tech

Most React devs still handle form submissions with a `loading` boolean. It works. But it creates that awkward pause where everything freezes while waiting for the server to respond. React 19 shipped `useOptimistic` to fix exactly this. The idea is simple: → User submits → UI updates instantly → Server processes in the background → Error? It auto-reverts to the previous state Here's the actual code: const [optimisticName, setOptimistic] = useOptimistic( serverName, (current, newName) => newName ); async function handleSubmit(formData: FormData) { const name = formData.get('name') as string; setOptimistic(name); // instant UI update await updateName(name); // real server call } No separate loading state. No flickering button. The UI responds immediately, and React handles the rollback automatically if the server call fails. Works especially well with Next.js Server Actions - the combo feels really natural. I built a profile edit flow with this recently. Users don't even realize they're waiting for the server. Are you using `useOptimistic` yet, or still managing loading states the old-school way? #ReactJS #NextJS #TypeScript #Frontend #WebDev

🚀 What if your local development could ditch the maze of random ports and settle on stable, named URLs? Frameworks like Next.js, Express, and Nuxt automatically respect the PORT environment variable, but many—Vite, Astro, React Router, Angular—ignore it. That’s where portless steps in, auto‑injecting --port and --host flags to keep everything running without manual tweaks. Portless does more than just assign a port. It creates wildcard subdomains (e.g., tenant1.myapp.localhost) that route directly to each worktree, giving every branch its own clean URL. It even syncs /etc/hosts for custom TLDs, supports HTTP/2 for faster dev loads, and flags misconfigurations with a clear 508 error. All of this is powered by a tiny CLI that you can drop into your package.json for zero‑config everywhere. Takeaways: 👉 Replace random ports with .localhost or .test URLs 👉 Leverage subdomain routing for branch‑specific endpoints 👉 Enable HTTP/2 to speed up dev server responses 👉 Trust the auto‑hosts sync on Linux, but toggle it on Safari when needed Behind the technical convenience lies a simple truth: developers deserve environments that feel predictable and human‑centric. When URLs are stable, focus shifts from debugging ports to building meaningful experiences. How will you redesign your local dev workflow when the URL is as reliable as the code you write? #LocalDev #Portless #DevTools #Innovation #Leadership #DigitalTransformation #WhyPrinciple Reference: [https://lnkd.in/gdc4qRZS] 🔄 Share 👍 React 🌐 Visit www.aravind-r.com #AravindRaghunathan

1-minute guide to make things easy ! useEffect(),FetchData()....  We’re still writing 30 lines of code for a task that modern React handles in just one. By moving your fetchData() to a Server Component, you skip the "loading state" headache and ship zero JavaScript to the client. #ReactJS #WebDevelopment #Frontend #CleanCode #1MinuteGuide #CodingTips #NextJS #SoftwareEngineering

🚀 Handling Large Datasets in React Applications Many React apps start slowing down not because of React itself, but because of how we handle large datasets. Here are some strategies that consistently work in production 👇 ⚡ 1. Never Render Everything Rendering thousands of rows at once kills performance. Use: • Pagination • Infinite scroll • List virtualization (react-window / react-virtualized) Render only what the user can see. ⚡ 2. Fetch Data in Chunks Avoid loading the entire dataset. Prefer: • Server-side pagination • Cursor-based APIs • Lazy loading Let the backend do the heavy lifting. ⚡ 3. Separate Server State from UI State API data shouldn't be scattered across components. Use tools like: • TanStack Query • SWR This gives caching, request deduping, and smoother loading states. ⚡ 4. Prevent Unnecessary Re-renders Large lists rerendering can freeze the UI. Use: • React.memo for row components • useMemo for expensive computations • useCallback for stable handlers Rendering efficiency matters. ⚡ 5. Move Heavy Operations to the Backend For large datasets: • Filtering • Sorting • Searching These should happen on the server, not in the browser. #React #Frontend #WebPerformance #JavaScript #SoftwareEngineering #ReactJS #FrontendArchitecture

Struggling with slow React components? `useMemo` is your friend. React's `useMemo` hook optimizes performance by memoizing computed values. It only re-calculates a value when one of its dependencies changes, preventing expensive re-runs on every render. Imagine you have a complex data transformation or calculation. Wrapping it in `useMemo` means React will reuse the last computed result as long as the inputs remain the same. This significantly reduces CPU load and improves application responsiveness. Always specify your dependency array accurately to ensure correct behavior. Use `useMemo` judiciously where performance bottlenecks are identified, rather than everywhere. #React #Frontend #WebDevelopment #Performance #Optimization #JavaScript #ReactHooks
