A visual guide on React component useEffect lifecycle. How components mount and re-render in React and their relation with the useEffect hook is one of the most important concepts in React. To summarize, 1. When first-time components are inserted in the DOM, they're referred to as "mounted," then updated via rendering, and later "unmounted." 2. While mounting, a component initializes. 3. In the render stage, a virtual DOM gets created and compared, and in the commit stage, it gets painted to the browser. 4. Any effect gets executed during the commit. If the state changes, the component re-renders with vDOM creation during rendering, painting, and attaching to real DOM during the commit phase.

⚡ Next.js in 10 seconds | CodeAtoms Building modern web apps is easier when frontend and backend work together seamlessly. Next.js brings the best of both worlds: • Server-side rendering • Fast performance • Full-stack capabilities In this animation, Next.js connects UI and server like a pro inside a futuristic dev universe. If you're serious about React development, Next.js is a must-learn. #NextJS #ReactJS #FullStackDevelopment #WebDevelopment #JavaScript #Coding #CodeAtoms

If you're using React.js and still confusing useEffect with useLayoutEffect, here’s the simplest way to understand it: 🔹 useEffect() Runs after the browser paints the screen. ✅ Best for: API calls Event listeners Timers Logging Fetching data useEffect(() => { console.log("Runs after paint"); }, []); 🔹 useLayoutEffect() Runs before the browser paints the screen. ✅ Best for: Measuring DOM size/position Preventing UI flicker Synchronous DOM updates Animations/layout fixes useLayoutEffect(() => { console.log("Runs before paint"); }, []); 💡 Simple Rule: Use useEffect for most side effects Use useLayoutEffect only when layout or visual rendering matters ⚡ Quick Difference: useEffect → async after render useLayoutEffect → sync before paint Using the wrong one can lead to: unnecessary blocking layout shift flickering UI performance issues 🚀 React developers: If your UI jumps, flickers, or measures incorrectly… You probably need useLayoutEffect, not useEffect. #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #ReactHooks #useEffect #laravel #laravedeveloper #useLayoutEffect #Programming #SoftwareDevelopment #UIDevelopment

🚀 What is the difference between useEffect and useLayoutEffect? Many React developers use them interchangeably… but they behave very differently under the hood. 🔹 useEffect Runs after the browser paints the UI. This means it does not block rendering and is ideal for side effects such as: • API calls • Logging • Timers • Event listeners / subscriptions 🔹 useLayoutEffect Runs synchronously before the browser paints the UI. It blocks the paint until the effect finishes, which makes it useful for layout-related tasks like: • DOM measurements • Layout calculations • Preventing UI flicker • Animations based on element size ⚡ Quick Rule to Remember 👉 useEffect → Runs after paint (non-blocking) 👉 useLayoutEffect → Runs before paint (blocks rendering) In large React applications, choosing the wrong hook can lead to performance issues or UI flicker. 💬 Have you ever faced a UI flicker bug that required useLayoutEffect instead of useEffect? #ReactJS #React #ReactNative #FrontendDevelopment #WebDevelopment #JavaScript #SoftwareEngineering #WebDev #FrontendEngineer #SoftwareDeveloper #Programming #Coding #CodeNewbie #TechCommunity #100DaysOfCode #DevCommunity #OpenSource #FullStackDeveloper #WebPerformance #UIUX #JavaScriptDeveloper #FrontendTips #CodingTips

I've been experimenting with custom route transitions to make navigating between pages feel a bit more native and alive. To build this, I used Next.js and next-transition-router to handle the actual page rendering logic, custom SVGs for the wave layers, and GSAP to animate the sweeps. Getting the animations to sync perfectly with the route changes took a bit of fine-tuning, but the final result makes the whole site feel much more cohesive. I've opened up the source code for anyone who wants to check it out.

A small React fun fact that changes how you think about performance: It’s not the DOM update that hurts the most. It’s what the browser does after it. When you change something in the DOM, the browser may: → recalculate layout (where everything sits) → repaint pixels on the screen And that can be more expensive than the JavaScript itself. Which means: You can have perfectly optimized React code… and still ship a slow UI. Example: Changing width, height, top, left → triggers layout Changing transform, opacity → usually avoids it That is why animations using transform feel smoother. React optimizes rendering. But the browser decides the real cost. Understanding this is where frontend becomes engineering, not just coding. #Frontend #React #Performance #WebDevelopment #JavaScript

When I first learned React, I thought #useEffect and #useLayoutEffect were basically the same. They are not. The key difference is when they run in the rendering cycle. Many React developers confuse useEffect and useLayoutEffect — but the difference can impact both performance and user experience. 🔹 useEffect Runs after the browser paints Non-blocking Perfect for: API calls, logging, timers, updating document title 🔹 useLayoutEffect ->Runs before the browser paints -> Blocks rendering until finished Best for: DOM measurements, layout changes, preventing UI flicker, animations Simple rule to remember: Use useEffect by default Use useLayoutEffect only when you must read or modify DOM layout before paint Understanding this difference helps you write more performant and smoother React applications. #React #FrontendDevelopment #MERN_STACK #WebDevelopment #JavaScript #ReactJS #Programming #SoftwareEngineering

Do you know why we have to use useLayoutEffect rather than useEffect? Most React developers use useEffect for everything — but there's a hidden trap waiting for you. The Analogy Think of moving into a new house: useEffect = You move furniture in, guests see the messy room for a second, THEN you fix it. There's a brief visible flash. useLayoutEffect = You fix everything BEFORE guests walk in. No flicker. No mess. 🔑 Key Differences useEffect — runs after the browser paints. Non-blocking. Best for: API calls, subscriptions, analytics. useLayoutEffect — runs before the browser paints. Synchronous. Best for: measuring DOM elements, preventing visual flicker, repositioning tooltips. The golden rule? Start with useEffect. Only reach for useLayoutEffect when you see a visual flicker or need a DOM measurement before the user sees the screen.
