Boost Vue.js App Performance with 3 Simple Tweaks

Slow frontend apps kill trust. 🛑 Before you rewrite, try these 3 tweaks I use to boost Vue.js performance: 1️⃣ Lazy Loading components 2️⃣ v-once for static content 3️⃣ ShallowRef for large datasets Keep it lean. Keep it fast. ⚡️ #VueJS #WebPerformance #CodingTips

🚀 Stop re-rendering your entire React app — here's why it's hurting you. One of the most common mistakes I see in React codebases is placing state too high in the component tree. When state lives at the top, every tiny update triggers a cascade of re-renders — even for components that don't care about that change. Here's what I do instead: ✅ Co-locate state — keep state as close to where it's used as possible. ✅ Use React.memo wisely — memoize components that receive stable props. ✅ Split context — separate frequently changing data from static config. ✅ Reach for useMemo & useCallback — but only when profiling confirms it helps. The result? A snappier UI, cleaner architecture, and fewer mysterious bugs. The React team built these tools for a reason — it's just about knowing when and where to apply them. 💬 What's your go-to trick for keeping React apps performant?

Most React devs are still making users wait for the server. 🙄 I was too. Until I found `useOptimistic` in React 19. **What changed:** → UI updates the moment user clicks → No spinner, no waiting, no freeze → If server fails - React auto rolls back to previous state → Zero extra code for error handling This is exactly how Instagram, X, and LinkedIn build their like buttons. The difference between a "good app" and a "feels native" app is this one pattern. `useOptimistic` ships with React 19. No extra install. If you're still on the old pattern - try this today. Drop a 🔥 if this was new to you! What pattern do you use for instant UI feedback? Let me know 👇 #React19 #ReactJS #useOptimistic #Frontend #WebDevelopment #JavaScript #FullStackDeveloper

⚡ Speed up your React app with Lazy Loading! Instead of loading everything at once, lazy loading loads components only when needed making your app faster and lighter. Just 3 simple steps: ✅ Import lazy & Suspense from React ✅ Wrap your component with lazy() ✅ Use <Suspense> with a fallback UI That's it! Your app now loads smarter, not harder. 🚀 #React #WebDevelopment #JavaScript #Frontend #ReactJS #100DaysOfCode

🚀 Just launched: react-state-vitals A zero-config memory & render monitor for React apps. While working on production apps, I kept asking: 👉 Why is this component re-rendering so much? 👉 Which store is growing in memory? 👉 Where is my performance actually going? So I built a tool to make this visible — instantly. 🧠 react-state-vitals gives you a live floating panel in development: • 📊 Store size tracking (Zustand, Context, React Query) • 🔁 Re-render counts per component • 🧬 JS heap usage insights • ⚡ Zero setup — just install and see Think of it as: 👉 “Vitals for your React state & memory” 📦 Try it here: https://lnkd.in/gU692hyT 🔥 Next I’m planning: • DevTools-like overlay • Identify memory-heavy components in real time • Visual performance timeline Would love feedback from fellow devs 🙌 What would you want this to track next? #React #JavaScript #Frontend #WebPerformance #OpenSource #NextJS #Zustand

#Vue_template_ep_1 In the previous post, I mentioned that I’ve been working on a Vue template. Today I’ll talk about the structure I’m using. So I adopted a modular structure in order to construct it. Instead of organizing everything by file type (all components in one folder, all composables in another, ...), I split the app into modules, each module represents a feature and contains everything it needs: components, pages, composables, and utils ..., This changes how you work with the code. With a flat structure, features are spread across many folders. Small changes often require jumping between multiple places. Over time, it becomes harder to understand the full context of a feature. With a modular structure, everything related to a feature is in one place. It’s easier to read, easier to maintain, and easier to remove or update without affecting the rest of the app. It also scales better. As the project grows, you don’t end up with large folders full of unrelated files. For me, it’s less about preference and more about control. Each feature becomes a small, isolated unit instead of being mixed into a global structure. #vuejs #typescript #frontend

⚠️ Your React App Isn’t Slow… You’re Just Rendering Too Much. I used to think UI lag was normal as my React projects grew. Turns out — I was wrong. The real problem? 👉 Unnecessary re-renders killing performance. Here’s what I changed: • Used React.memo to stop useless re-renders • Avoided redundant state updates • Fixed messy useEffect dependencies • Broke large components into smaller reusable pieces And the impact? • Faster UI • Better performance • Cleaner codebase Biggest lesson: React doesn’t slow down — poor optimization does. Now I’m more focused on how components render, not just what they render. #reactjs #webdevelopment #mernstack #frontend #performance #javascript

🧵 Day 5 of 40 — React System Design Series I used to wrap every function in useCallback. Every. Single. One. I thought that's what senior React devs did. Turns out I was making my app slower, not faster. Here's what I learned about useMemo, useCallback, and React.memo: → Memoisation has a cost — it's not free → The trio only works when all three are used together → The Profiler-first rule: measure before you memoize → Exactly when each one helps (and when it's just noise) Full breakdown with real TypeScript code 👇 https://lnkd.in/g5rcJ7qJ #ReactJS #SystemDesign #Frontend #LearningInPublic #WebDevelopment

React is easy to start… But hard to master. At first, it’s just components and props. But then you realize the real game: 👉 State management 👉 Performance optimization 👉 Re-render control A small mistake in structure can slow down your entire app. What I’ve been focusing on: ✔ Writing reusable components ✔ Avoiding unnecessary re-renders ✔ Keeping logic clean and scalable Because good UI isn’t just about looks… It’s about performance + maintainability. #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #UIUX

If your React app “feels slow” but Lighthouse looks fine, the bottleneck is usually inside your render loop. 🧠⚡ In large-scale apps, performance issues often come from a few repeat offenders: 🔁 Unstable props: inline objects/functions causing child re-renders 🧩 Over-wide state: a tiny change triggers a whole tree 📦 Heavy lists: rendering 5k rows when the user sees 20 🕵️ Accidental work: expensive selectors/formatting done every render My debugging flow: 1) React DevTools Profiler: record a real interaction, sort by “self time” ⏱️ 2) Find “why did this render?”: check prop identity + state ownership 🔍 3) Fix the source, not the symptom: - memo/useMemo/useCallback only after you prove churn - split state by concern; colocate state closer to where it’s used - virtualize long lists; defer non-critical UI with transitions - move expensive computations to memoized selectors or the server Real-world impact: these fixes cut CPU + battery drain on mobile, stabilize dashboards, and reduce infra costs when Next.js pages stop re-rendering on every keystroke. 📉📱 What’s your most common React perf culprit lately? 👇 #react #nextjs #javascript #webperformance #frontend
