Avoid Running Out of API Limits with useEffect in React

Most React devs bring their SPA habits into Next.js — and their users pay the price. 👇 You've written it a hundred times: useState for data, useEffect to fetch it, a spinner while they wait. It works in React. In Next.js App Router, it's the wrong pattern entirely. Server Components let you fetch data inside the component — on the server, before the page hits the browser. No loading state. No extra JS bundle. No hydration issues. HTML that arrives ready. I've swapped dozens of useEffect fetch patterns for async Server Components and the Lighthouse scores jump immediately. Use the server for reads. Use useEffect for things only the browser can do. #NextJS #ReactJS #WebDevelopment #JavaScript #TypeScript #AppRouter #ServerComponents #ReactHooks #FrontendDeveloper #SoftwareEngineer #CleanCode #100DaysOfCode #WebPerformance #Programming #WebDev #NextJS14 #FullStackDeveloper #CodeQuality

React developers sometimes face tricky behavior of React. For example: in some specific situations, same-name component-instances re-render each other, instead of doing a fresh independent new mount. This image shows this tricky situation and the solution which is the "key" prop of a component. The different "key" prop forces the component to behave independently even if it has the same name ("Item").

🚀 React Quick Revision Here are some important React concepts explained in short 🔹 1) Which is the entry file in React? 👉 In most React apps, the entry file is index.js / main.jsx 👉 It is responsible for rendering the root component: ReactDOM.createRoot(document.getElementById("root")).render(<App />); 🔹 2) What is the datatype of useEffect second argument? 👉 It is an Array useEffect(() => {}, [dependency]); 👉 This array is called the dependency array and controls when the effect runs. 🔹 3) useState syntax explanation (arrow understanding) const [state, setState] = useState(initialValue); 👉 Breakdown: const → variable declaration [state, setState] → array destructuring useState() → hook function setState → function to update state 👉 Arrow meaning: setState is a function → used to update value 🔹 4) Difference between Tag and Component 👉 Tag (HTML Element): <div>Hello</div> Built-in HTML element Lowercase naming 👉 Component (React): <MyComponent /> Custom reusable function Always starts with uppercase Returns JSX #ReactJS #FrontendDeveloper #JavaScript #WebDevelopment #Learning

Understanding State Management in React JS is a game changer for every frontend developer 🚀 From managing simple local states to handling complex global data, mastering this concept helps you build scalable and efficient applications. In this post, I’ve simplified: ✔ What is State ✔ How it works in React ✔ Local vs Global State ✔ Popular tools like Context API, Redux & Zustand If you're learning React, this is one concept you can't afford to ignore 💡 👉 Save this post for later & share your thoughts in the comments CODING OF WORLD #ReactJS #WebDevelopment #FrontendDevelopment #JavaScript

🔹 React Basics: Props vs State (Explained Simply) When starting with React, one of the most important concepts to understand is the difference between Props and State. Here’s a simple breakdown 👇 👉 Props (Properties) • Passed from parent to child components • Read-only (cannot be modified) • Used to make components reusable 👉 State • Managed within the component • Can be updated using hooks like `useState` • Controls dynamic data and UI behavior 💡 In short: Props help you pass data, while State helps you manage data. Understanding this difference is key to building scalable and maintainable React applications.

most React developers use useCallback wrong. not because they don't understand it. because they were taught the wrong rule. the rule they heard: "wrap functions in useCallback to prevent unnecessary re-renders. the actual rule: useCallback only helps when you pass that function to a child component wrapped in React.memo or as a dependency in useEffect. that's it. useCallback doesn't prevent re-renders of the parent. it just memoizes the function reference so children don't see a "new" function every render. three questions to ask before reaching for useCallback: - is this function passed to a memoized child component? - is this function a dependency in a useEffect? - is this function expensive to recreate? if none of these just write the function normally. the best optimisation is usually the one you don't add. #reactjs #typescript #webdevelopment #buildinpublic #javascript

🚀 React Performance Optimization (TypeScript) Today I worked on enhancing application performance by applying some essential React optimization techniques using TypeScript. 🔍 What I explored & implemented: • Utilized useMemo to cache heavy computations and reduce unnecessary recalculations • Used useCallback to avoid repeated function creation on re-renders • Implemented React.memo to prevent avoidable component updates • Improved overall rendering performance ⚙️ Impact: ✅ Minimized unnecessary re-renders ✅ Boosted component efficiency ✅ Faster and smoother UI interactions ✅ Cleaner, more maintainable codebase 💡 Key Insight: Knowing when to use useMemo, useCallback, and React.memo makes a big difference in building scalable and high-performance React apps. 📈 Still learning and experimenting with real-world performance optimization techniques. #ReactJS #TypeScript #FrontendDevelopment #WebPerformance #JavaScript #ReactOptimization #LearningInPublic #100DaysOfCode

Every time I start a new React project, I copy the same 5 hooks. Not from a library. From my own collection, battle-tested across 15+ production apps. These aren't clever abstractions. They're boring, reliable utilities that eliminate the same bugs I've fixed dozens of times: 1. useDebounce — stop hammering your API on every keystroke 2. usePrevious — track previous values without infinite re-render loops 3. useLocalStorage — state that survives refresh (SSR-safe, GDPR-aware) 4. useMediaQuery — responsive logic, not just responsive styles 5. useAbortController — cancel requests on unmount, prevent race conditions 5 files. ~150 lines total. Zero dependencies. Senior engineers don't write more code. They carry better defaults.

Good list - this is basically the 'React starter pack' ))) I’d add one more that saved me a lot of headaches - useAsync (or useRequest) - wraps loading/error/data + cancellation in one place. Especially useful when combined with AbortController to avoid race conditions and stale state updates.
