Custom React Hooks with TypeScript Benefits

🚀 Using the useState Hook to Manage State (React Development) The `useState` hook is the primary way to manage state in functional React components. It allows you to declare a state variable and a function to update it. When the update function is called, React re-renders the component with the new state value. This hook simplifies state management compared to class components and makes your code more readable. Remember to import `useState` from React before using it.

Your Next.js app is slower than it should be — here's why.!! Most developers use lazy loading or eager loading. But there's a smarter middle ground — and it changed how I build with Next.js. Here's what I mean: ❌ *Eager loading* = everything loads upfront → huge initial bundle → slow app ❌ *Lazy loading* = loads only when clicked → user sees a spinner → bad experience ✅ *My approach* = Predictive preloading* I use `next/dynamic` with named exports and custom loading skeletons — but not just for code splitting. I preload components *invisibly* when the user hovers or scrolls near a navigation element. So by the time they click — it's already there. Instant. No spinner. The result? → Smaller initial bundle → Faster Time To Interactive (TTI) → Navigation that feels instant → Cleaner, maintainable code It's not lazy. It's not eager. It's *intentional.* If you're building with Next.js and haven't tried this — you're leaving performance on the table. Have you ever tried predictive preloading?

🚀 Boost Your React App Performance Like a Pro Most developers focus on building features… But performance is what truly defines a great user experience ⚡ Here are 5 powerful concepts that helped me optimize my React apps 👇 🔹 React.memo Prevents unnecessary re-renders by memoizing components 🔹 useMemo Optimizes expensive calculations by caching results 🔹 useCallback Avoids function re-creation and prevents unwanted re-renders 🔹 React Suspense Displays a fallback UI while components are loading 🔹 Lazy Loading (Code Splitting) Loads components only when needed → faster initial load 💡 Key Takeaway: 👉 Don’t optimize everything optimize what matters Focus on: ✔ Heavy components ✔ Frequent re-renders ✔ Expensive calculations ⚡ Result: ✅ Faster apps ✅ Better performance ✅ Smooth user experience #reactjs #frontend #webdevelopment #javascript #reactdeveloper #performance #coding #softwaredeveloper #webperf

Most React frontend apps don’t fail loudly They fail silently. No warning. No error message. Just a white screen and confused users leaving your app. The scary part? This can happen even if your load time is perfect and your UI looks flawless. One small mistake One crashing component And your whole app disappears. Here’s how to fix this in 2 minutes #React #Frontend #JavaScript #ReactJS #FrontendDevelopment

⚡ 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

After 3 years of building React Native apps, I realized something important: Responsive design is not about flexbox. It’s about building a system. I used to write things like: fontSize: 14 padding: 16 It worked… until I started supporting multiple devices. Everything broke. That’s when I shifted to a scalable UI system using: • scaling functions • design tokens • reusable components I wrote a full breakdown here 👇 https://lnkd.in/g7JkvmHS #ReactNative #MobileDevelopment #SoftwareEngineering #Frontend #JavaScript

🚀 Boosting React Performance with memo If you're working with React apps, you’ve probably faced unnecessary re-renders that slow things down. That’s where React.memo comes in 👇 💡 What is React.memo? It’s a higher-order component that helps you skip re-rendering a component when its props haven’t changed. ⚡ Why it matters? Prevents unnecessary renders Improves performance in large apps Keeps UI responsive 🛠️ Quick Example: const UserCard = React.memo(({ name }) => { console.log("Rendered!"); return <h2>{name}</h2>; }); Now, UserCard will only re-render if name changes—not every time the parent updates. 🎯 When should you use it? ✔️ Frequently re-rendering components ✔️ Expensive UI rendering ✔️ Stable props ⚠️ Pro Tip: Don’t overuse memo. It’s a performance optimization, not a default pattern. 📌 Smart optimization > premature optimization. #ReactJS #FrontendDevelopment #WebPerformance #JavaScript #CodingTips #SoftwareEngineering

🚀 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?

Day 10 - Frontend Diaries 👉 I thought React automatically optimizes everything While working with React, it’s easy to assume that it handles performance by default components re-render UI updates and everything just works But while building and observing behavior, I realized that React does not automatically optimize everything Unnecessary re-renders still happen props changes still trigger updates state changes can affect multiple parts of the UI React gives you the tools but how you use them decides performance Understanding when components re-render and how data flows through them becomes important as the app grows That’s when I realized React does not optimize your app for you it helps you build it, but optimization is still your responsibility #frontenddevelopment #reactjs #webdevelopment #fullstackdeveloper #softwareengineering #buildinpublic #buildinpublic #developers

⚠️ Common React Native Mistakes Developers Still Make After working on multiple production apps, I’ve noticed some common mistakes that can seriously impact performance and user experience 👇 ❌ 1. Unnecessary re-renders Not using useMemo / useCallback properly can slow down your app ❌ 2. Poor state management Messy state = hard-to-maintain and buggy apps ❌ 3. Ignoring performance optimization FlatList without optimization = laggy UI ❌ 4. No proper error handling in APIs Users hate when apps break without feedback ❌ 5. Overusing third-party libraries More dependencies = more problems --- ✅ What I’ve learned: Keep it simple, optimize early, and always think about the user experience Small improvements can make a BIG difference 🚀 --- What’s one mistake you learned the hard way in React Native? 👇 #ReactNative #MobileDevelopment #JavaScript #AppDevelopment #SoftwareEngineering #CodingTips
