The Interactive Guide to Rendering in React https://buff.ly/3YAfmQp What is rendering?Put simply, rendering is just a fancy way of saying that React calls your function component with the intent of eventually updating the View.When React renders a component, two things happen. First, React creates a snapshot of your component which captures everything React needs to update the view at that particular moment in time. props, state, event handlers, and a description of the UI (based on those props and state) are all captured in this snapshot. From there, React takes that description of the UI and uses it to update the View.

React Devs: Are You Using useEffect and useLayoutEffect Correctly? Here’s When to Use Each! React gives us two hooks for side effects—useEffect and useLayoutEffect—and using them correctly can significantly impact performance and user experience. Let’s break down the differences: 🔄 useEffect Timing: useEffect runs asynchronously after the paint. This means it doesn’t block the browser from updating the UI, which makes it ideal for effects that don’t impact the visual layout. Ideal For: Non-visual side effects like data fetching, updating the document title, logging, and setting up event listeners. Pros: Improves performance by letting the browser paint the UI without delay. ⏱️ useLayoutEffect Timing: useLayoutEffect runs synchronously after the DOM update but before the paint. This means it blocks the browser until it completes, so it’s critical to use it only when necessary. Ideal For: Layout-sensitive tasks where you need immediate access to the updated DOM (e.g., measuring element dimensions, synchronizing animations, or repositioning elements). Pros: Ensures that any layout changes happen before the user sees the UI, helping to prevent flickers or visual shifts. ⚖️ When to Use Each Stick with useEffect for most side effects that don’t affect layout directly. It’s better for performance and keeps the UI responsive. Use useLayoutEffect only when you need synchronous DOM updates before paint to prevent flickering or layout shifts. 💡 Rule of Thumb: If your side effect impacts layout, use useLayoutEffect; for everything else, stick with useEffect. #React #WebDevelopment #FrontendDevelopment #ReactTips

useLayoutEffect in React useLayoutEffect is a React Hook that is similar to useEffect, but it differs in when it is executed during the component lifecycle. It allows you to run synchronous effects after all DOM mutations are complete but before the browser has painted the updated UI. Key Features of useLayoutEffect: 1. Execution Timing: • Runs synchronously after all DOM updates (mutations) but before the browser has a chance to paint the changes. • This is earlier than useEffect, which runs asynchronously after the paint. 2. Use Case: • Ideal for situations where you need to measure or modify the DOM before the user sees the update. Examples: • Measuring element sizes and positions. • Applying animations or styles that depend on the updated DOM. • Preventing flickers or layout shifts caused by DOM changes. 3. Callback Signature: useLayoutEffect(() => { // Perform synchronous DOM-related operations here. return () => { // Clean up effects (like event listeners) when the component unmounts. }; }, [dependencies]); 4. Arguments: • Callback: A function containing the effect logic. • Dependencies Array: Specifies when the effect should re-run, similar to useEffect Example: Measuring DOM Size import React, { useLayoutEffect, useRef, useState } from "react"; function Example() { const divRef = useRef(null); const [width, setWidth] = useState(0); useLayoutEffect(() => { if (divRef.current) { setWidth(divRef.current.offsetWidth); } }, []); return ( <div> <div ref={divRef} style={{ width: "50%" }}> Resize this element </div> <p>The width is: {width}px</p> </div> ); } When to Use useLayoutEffect? • Rarely! Most of the time, useEffect is sufficient. Use useLayoutEffect only when: 1. You need to measure the DOM or modify it before the paint. 2. You want to prevent UI flickering or layout shifting.

🌟 Excited to share my latest project: Awarded UI of Refokus.com! 🚀 🔗 Project Link: https://lnkd.in/gV7TcQbV The Refokus.com UI is a result of meticulous effort and showcases my expertise in React.js, Lenis, and Framer Motion. This project emphasizes smooth transitions, micro-interactions, and detailed animations, all while staying true to the award-winning design of Refokus. The clone delivers a sleek, polished, and interactive user experience that mirrors the original website, highlighting the seamless integration of modern design trends and advanced UI concepts. Challenges in Creating Smooth Interactions: Crafting these micro-interactions and ensuring pixel-perfect precision required deep dives into Lenis for smooth scrolling and Framer Motion for fluid animations. The pursuit of delivering an interactive yet visually stunning experience required perseverance and attention to every small detail. I would love to hear your feedback and suggestions as I continue honing my skills and pushing boundaries in web development! #webdevelopment #webdeveloper #reactjs #lenis #framermotion #frontenddevelopment #uiux #awardwinningdesign #refokus #animation #react #javascript #smooth

👨💻 Update on the GCAS Regina website built with React and CMS integration for the update of events. A few weeks ago, I shared screenshots of the design and code of this website that I was working on. This was built from scratch with React JS for the frontend and Sanity CMS for the backend. The video shows the state of the event section when it is empty (when there are no events). Also it showcases the responsiveness of the website on all screens from large to small. It also renders a 404 page with a very nice animation to increase the overall user experience and a link to take the user back to the homepage. In the next post, I will share a video of the website with events and some of the resources I used and also where I got the cool animations from. Stay tuned for more frontend content like this and my journey in frontend development. #frontenddevelopment #figma #ux #ui #reactjs #sanitystudio #webdevelopment #webdesign #webdeveloper
