How to avoid endless re-renders with useEffect in React

⚡ Express.js Tip — Speed up your site instantly! Performance isn’t just about writing fast code — it’s about sending responses efficiently. Two quick wins for every Express app 👇 🚀 compression() — compresses responses to make payloads smaller. 📦 express.static() with maxAge — caches static assets in the browser. These two lines can significantly boost your app’s performance, especially for users on slow connections. Make it fast. Make it smooth. 💨 #NodeJS #ExpressJS #Performance #WebDev #JavaScript #CodingTips

Just built a simple React Counter App using Vite! Today I created a small but handy project while brushing up on React fundamentals. This Counter App uses the useState hook to update the UI in real time as the user increments or decrements the value. Here’s the core logic I implemented: const [count, setCount] = useState(0); const addValue = () => { setCount(count + 1); }; const removeValue = () => { setCount(count - 1); }; This project helped me refresh key concepts like: 🔹 State management with useState 🔹 Event handling in React 🔹 JSX rendering 🔹 Vite + React project setup Small projects like this are great reminders that even simple components teach powerful ideas.

APIs in Next.js — Pages Router vs App Router When I first built APIs in Next.js, it felt amazing to have both frontend and backend in one place. Both the Pages router and App router have this feature, but with the App Router, things got even better. Here’s the difference 👇 👉 Pages Router — You create API routes inside the pages/api/ folder. Each file becomes an endpoint, e.g. pages/api/user.js → /api/user. Simple and perfect for most use cases. 👉 App Router — Introduced in Next.js 13+, APIs are now route handlers inside the app/api/ folder. You can export functions like GET, POST, PUT, etc., just like in Express — but with the flexibility of modern React and server components. For me, the App Router made APIs feel more structured, modern, and easier to scale. It’s clean, intuitive, and definitely the future of Next.js backend logic. 🚀 #NextJS #ReactJS #WebDevelopment #JavaScript #Frontend #APIs

✅ 4. Component Reusability — A Superpower A single component can be used 10, 20, or 100 times with different data. Example: 🟦 Button Component You change it once → It updates everywhere in the app. That's real development power. ✅ 5. What Makes a Good React Component? A clean React component should be: ✔ Small ✔ Focused on one job ✔ Reusable ✔ Easy to test ✔ Readable ✔ Free from unnecessary logic Small components = fewer bugs + faster iteration. #FrontendBestPractices #ReactTips #WebDev #ReactJS #CleanCode #Reusability

🚀 Understanding React Hooks — The Power of useState 🔄 Today while exploring React, I revisited one of its most powerful concepts — Hooks, especially useState(). Here’s a simple example 👇 function App() { let [counter, setCounter] = useState(15); let addValue = () => { setCounter(counter + 1); }; let removeValue = () => { setCounter(counter - 1); }; return ( <> <h1>My First App React </h1> <h2>Counter value: {counter}</h2> <button onClick={addValue}>Add Value</button> <br /> <button onClick={removeValue}>Remove Value</button> </> ); } ✨ What I learned: Normal JavaScript variables don’t trigger re-renders when their value changes. useState lets React track changes and automatically update the UI. It keeps state values persistent across re-renders, unlike normal variables that reset each time. 💡 In short, useState gives life to our components — making them dynamic and interactive! #React #JavaScript #FrontendDevelopment #WebDevelopment #LearningInPublic #ChaiAurReact

Your component renders fast in isolation, but in the app... it stutters? Been there. I was recently debugging a laggy table in a React app. Thought it was the data size or some heavy computation. Turned out the real issue? Unnecessary re-renders. 🔍 Even with only a few rows, toggling a filter caused the *entire table* (and worse, surrounding components) to re-render. Why? Because I passed a new inline function and object props each time. And React, being React, re-renders when it *thinks* things changed. The fix was surgical, but powerful: 1. Wrapped the row component in `React.memo` 2. Memoized props with `useMemo` and `useCallback` 3. Tracked what *actually* changed using the React DevTools Profiler #ReactJS #WebPerformance #ReactTips #Frontend #JavaScript #DevLife #Optimization #TechShare

Looking to learn Next.js in 2025? Here are 3 habits to get you started. If you're jumping into Next.js this year, the docs alone won't make you a better developer but your habits will. Here are 3 habits to help you progress quickly: 1️⃣ Create small, real projects (not tutorials). Please stop jumping from video-to-video on Youtube. Pick small ideas - a notes app, simple dashboard, or landing page, and build them from end to end. Next.js only clicks once you actually ship something. 2️⃣ Understand the "why" and not just the "how". Why Server Components? Why App Router? Why caching and data-fetching patterns are important? When you understand the why, the framework becomes 10× easier. 3️⃣ Consider performance from Day 1. Next.js is powerful, but slow code is still slow code. You will want to learn how to measure bundle size, optimize queries and use the correct rendering strategy. All of these small habits will make your apps feel premium. If you can stick to these three habits, I assure you, you will be ahead of 90% of aspiring developers this year. Your future self will thank you. 🚀 #Nextjs #ReactJS #WebDevelopment #FrontendDevelopment #JavaScript #FullStackDeveloper #Programming #LearnToCode #DeveloperCommunity #CodingJourney

Ever have your app get stuck in an infinite loop and not know why? 🙋♂️ Happened to me today. My browser tab completely froze. The culprit was a sneaky `useEffect` hook. I was passing an object directly into the dependency array: `useEffect(fetchData, [filters]);`. This is a classic trap! On every render, the `filters` object was a 𝐧𝐞𝐰 𝐨𝐛𝐣𝐞𝐜𝐭 𝐢𝐧 𝐦𝐞𝐦𝐨𝐫𝐲. React’s dependency check uses referential equality (`===`), so it saw a "new" dependency every time. Boom, infinite loop. 💥 It’s a subtle bug that can sneak past anyone. 🧠 The fix: either memoize the object with `useMemo` or just destructure and pass primitive values to the array. Have you struggled with this before? #ReactJS #FrontendDevelopment #DeveloperTips

Redux vs Zustand: When I first started managing state in React Native, Redux was my go-to. It was powerful, popular, and everyone around me seemed to use it. But as my projects grew, I started asking myself: “Why does toggling a simple value need so much setup?” Reducers, action types, dispatch... it all started to feel heavy — especially for small or medium apps. Then I discovered Zustand, and everything just clicked. ✅ No context. ✅ No reducers. ✅ Just a few lines of code — clean, predictable, and efficient. Zustand plays beautifully with TypeScript and scales effortlessly as the app grows. These days, it’s my go-to for local state management — no boilerplate, no extra headaches. #ReactNative #Redux #Zustand #StateManagement #MobileDevelopment #JavaScript #ReactJS #Android #lOS
