Angular App Auto Refresh with Version Check

What is useDeferredValue? useDeferredValue is a React Hook that returns a deferred version of a value — meaning React can postpone updating it until more important work is done. const deferredValue = useDeferredValue(value); When value changes: - React first renders with the old value - then updates the deferred value in the background This makes the UI feel responsive, even if some parts are slow. There is the example on the screenshot and there: - input updates immediately (high priority) - results update later (low priority) useDeferredValue is about prioritization. That small shift makes a huge difference in real-world UX — especially in data-heavy or interactive apps. #react #frontend #webdev #javascript #reactjs #performance

New project completed! 🚀 Sharing my latest React build: a fully functional interactive calculator. For this app, I focused on applying core React best practices: 🔹 Modularization: Clean code splitting with reusable components (Button, Screen). 🔹 Hooks: State management for mathematical logic and input flow. 🔹 UI/UX: Clean and responsive styling for an intuitive user experience. Check out the video below to see it in action! I'll leave the link to the GitHub repository in the first comment. 👇 #ReactJS #Frontend #WebDevelopment #JavaScript #SoftwareEngineering

A common UX pain point I often notice in Next.js Server Components 👇 When a user clicks a link, Next.js navigates to something like /link/[id]. If that route is a Server Component, it runs the DB queries on the server before sending any HTML back to the browser. During that fetch time, the UI often shows no immediate feedback, which can make the app feel stuck or unresponsive. The fix is surprisingly simple ✨ Just add a loading.tsx file. This is a built-in Next.js convention. For example: app/projects/[id]/loading.tsx The moment navigation starts, Next.js instantly renders this loading UI while the server component fetches data in the background. This small addition makes navigation feel significantly faster and smoother. Sometimes great UX is not about speeding up the backend it’s about making the wait feel seamless. 😊 That’s one of the things I really appreciate about how NextJs handles Server Components so elegantly. #nextjs #react #webdevelopment #frontend #ux #javascript #fullstack #developerexperience

Fixing Layout Shift Issues in React Caused by Late Loading Content Ever noticed your 𝗨𝗜 𝗷𝘂𝗺𝗽𝗶𝗻𝗴 around just when everything seems loaded? That’s a classic layout shift issue — and in React apps, it often happens 𝗱𝘂𝗲 𝘁𝗼 𝗹𝗮𝘁𝗲-𝗹𝗼𝗮𝗱𝗶𝗻𝗴 content like images, fonts, or async data. 𝗜𝗻 𝘁𝗵𝗶𝘀 𝗽𝗼𝘀𝘁, 𝗜 𝗯𝗿𝗲𝗮𝗸 𝗱𝗼𝘄𝗻: • Why layout shifts happen in React • How late-loading elements impact user experience (and 𝗖𝗼𝗿𝗲 𝗪𝗲𝗯 𝗩𝗶𝘁𝗮𝗹𝘀) • Practical techniques to prevent it — from reserving space to using 𝘀𝗸𝗲𝗹𝗲𝘁𝗼𝗻 𝗹𝗼𝗮𝗱𝗲𝗿𝘀 • Real-world patterns you can apply immediately in your projects A smooth UI isn’t just about design — it’s about stability.

Choosing a data grid in a React app is one of those decisions that quietly shapes everything: performance, UX, and how fast your team can ship. This comparison of AG Grid, React Table, and Ext JS Grid does a nice job of showing the tradeoffs between raw power, flexibility, and complexity. It reminded me how often we default to "what we used last time" instead of matching the grid to the actual use case. Worth a read if you're dealing with big tables, heavy filtering, or complex data workflows: https://lnkd.in/dyA4vRV5 #reactjs #frontend #webdevelopment

Most developers think the bridge is a bottleneck to avoid. The reality? Mastering it transforms your app's performance and scalability. React Native’s bridge connects native code with JavaScript. It’s easy to treat it like a black box or a performance wall. But understanding its async messaging system helped me reduce lag in a recent app by batching bridge calls and minimizing data sent. In one project, we faced UI stutters because too many bridge messages piled up during animations. Refactoring to send fewer updates and offload logic to native modules smoothed the experience. The takeaway: the bridge isn’t just a limitation—it’s your app’s pulse. Knowing when and how to cross it can unlock better UX and faster development cycles. How have you managed the bridge in your React Native projects?

You click 'Like' on a post. The heart turns red instantly. ❤️ But did the server confirm it? Not yet. That's Optimistic Updates — and it's one of the smartest UX tricks in frontend development. --- Here's the idea: Instead of waiting for the server to respond, you update the UI immediately — then reconcile once the response arrives. ✅ Server succeeds → nothing changes, user never noticed the gap ❌ Server fails → you roll back silently --- Why does it matter? → Your app feels instant, even on a 3G connection → Users don't stare at loading spinners for simple actions → The difference between a "slow app" and a "fast app" is often just this one pattern --- But here's what we must get right: ✔ Always snapshot the previous state before updating the UI ✔ Roll back immediately if the server responds with an error ✔ Sync with the server after the request settles — success or failure Libraries like React Query make this clean with onMutate → onError → onSettled hooks. --- When TO use it: ✔ Likes, toggles, checkboxes ✔ Drag-and-drop reordering ✔ Read/unread status ✔ Auto-save form fields When NOT to: ✗ Payments ✗ Irreversible deletes ✗ Anything with real business consequences --- The rule of thumb: use optimistic updates when failure is rare and rollback is easy.

As a Frontend / UI Developer, one thing I still see in many modern web apps is this: Accessibility is often treated as optional — until it becomes a problem. Here are 5 common accessibility issues I still find during reviews and audits: 1️⃣ Missing or incorrect form labels 2️⃣ Poor keyboard navigation (Tab order / focus traps) 3️⃣ Low color contrast in text and buttons 4️⃣ Incorrect heading hierarchy (H1 → H4 → H2 chaos 😅) 5️⃣ Clickable elements built with <div> instead of semantic controls These issues may look small, but they directly impact: Keyboard-only users Screen reader users Users with low vision Overall usability for everyone Accessibility is not just compliance. It’s part of good engineering and better UX. If you’re building with React / Next.js / Angular / Vue, accessibility should be part of the development process — not a last-minute fix.

🚀 useDeferredValue might quietly replace debounce in your React apps… Most devs still do this: • setTimeout • clearTimeout • extra state • messy useEffect All just to “delay” updates. But React already solved this. With useDeferredValue: ✅  Your input updates instantly ✅  Expensive UI updates are deferred ✅  No manual delay logic Cleaner code. Better UX. Less bugs. 👉 Stop controlling time manually. Let React handle priority. #React #React19 #JavaScript #Frontend #WebDevelopment #CleanCode #DeveloperExperience

Most Next.js applications are not slow because the product is complex - they’re slow because of poor foundational decisions. I just went through a practical Next.js performance checklist, and it clearly explains why Lighthouse scores drop even in “modern” apps. First, images: incorrect usage of next/image and missing priority can instantly hurt LCP. Then fonts: without next/font, you almost guarantee unnecessary render blocking. The biggest silent performance killer is third-party scripts loaded synchronously, blocking everything. And yes, many projects are still shipping too much client-side JavaScript instead of leveraging Server Components. Caching (SSR / ISR / static) is often configured by habit, not based on real traffic patterns. The takeaway is simple: in Next.js, performance is not optimization - it’s an architectural decision from day one. So what’s your Lighthouse score in production right now - 90+ or “we’ll fix it later”? #Nextjs #WebPerformance #FrontendDevelopment #ReactJS #JavaScript #WebDevelopment #SoftwareEngineering #PerformanceOptimization #Lighthouse #CoreWebVitals #FrontendArchitecture #UX #EngineeringBestPractices
