🚀 Just Published: React + Lottie Animated Background Guide 🎬✨ Hi Everyone! 👋 I’ve just published a detailed guide on how to implement a smooth animated Lottie background in React applications. This is not a packaged component — it’s a practical implementation guide with full explanation and integration steps. 📘 GitHub Repo: https://lnkd.in/gXqaWT-F 🛠️ What the guide covers: ✅ Setting up Lottie in a React + TypeScript project ✅ Creating full-screen & contained animated backgrounds ✅ Adding dark mode, overlay & blur effects ✅ Performance optimization techniques (SVG renderer, layout containment, scaling) ✅ Clean project structure & implementation approach This guide is helpful if you're building: • SaaS dashboards • Authentication pages • Landing pages • Splash screens • Modern UI experiences If you're working with React + Tailwind + animations, this might save you some time. Would love your feedback or suggestions! 🙌 #ReactJS #Lottie #WebDevelopment #Frontend #TailwindCSS #TypeScript #OpenSource #UIUX #Developers

After months of building, I'm launching an open-source React component library next week. 50+ components. Built on Base UI. Styled with native CSS instead of Tailwind utilities. The thesis: your JSX should be readable, your styles should live in CSS, and your colors should be perceptually accurate (we use Google's HCT color science). More details dropping on launch day. Follow along if you're interested. #react #opensource #webdev #css

🎯 Most Developers Use React — But Misunderstand What “Render” Actually Means A lot of React confusion starts with one overloaded word: render. People hear “render” and imagine the browser instantly repainting the screen every time something runs. That’s not what React rendering really means. Here’s the clean mental model — in under a minute 👇 When React renders a component, it is mainly doing this: ➡ Reading your component function ➡ Executing the JSX logic ➡ Producing a new UI description ➡ Comparing it with the previous one ➡ Updating only the changed parts in the real DOM Rendering is a calculation step first — not a direct DOM update. Also, render is not a one-time event. It happens multiple times during a component’s lifecycle: ✅ First time component appears → Initial render (mount) ✅ When state changes → Re-render ✅ When props change → Re-render ✅ When parent re-renders → Child may re-render Important distinction: Mount = first render Update = every render after that Another key point many miss 👇 React does NOT blindly rewrite the entire DOM on every render. It updates a lightweight virtual tree, runs a diff, and patches only what changed. That selective update is what keeps React UIs fast and predictable. If you understand what render truly means, topics like memoization, re-renders, and performance optimization become much easier to reason about. Clarity beats memorization every time. 👉 Follow Rahul R Jain for more real interview insights, React fundamentals, and practical frontend engineering content. #ReactJS #FrontendDevelopment #ReactConcepts #VirtualDOM #ReRendering #WebDevelopment #JavaScript #FrontendEngineering #UIPerformance #ReactInterview

What Runs First in React? (Rendering vs useEffect vs useCallback vs useMemo) One day I wrote this small React code just to test my understanding: import { useEffect, useCallback, useMemo } from "react"; export default function App() { useEffect(() => { console.log("useEffect"); }, []); const increment = useCallback(() => { console.log("useCallback"); }, []); const squaredCount = useMemo(() => { console.log("useMemo"); }, []); return ( <div> {console.log("Rendering JSX")} </div> ); } And I asked myself: 👉 What runs first? At first, I guessed randomly. But then I stopped thinking like a coder… and started thinking like React. 🧠 Step 1: React always renders first React’s first job is simple: Build the UI. So this runs first: Rendering JSX Because React must render before doing anything else. 🧠 Step 2: During rendering While React is rendering: • useMemo runs immediately (it calculates something) • useCallback does NOT execute — it only stores the function So you’ll see: useMemo✅ But not: useCallback❌ That function only runs if we call increment() manually. That was my “aha” moment 💡 🧠 Step 3: After rendering → useEffect runs Once the UI is painted, React runs: useEffect Because useEffect always runs after render. ✅ Final Order (on first mount) 1️⃣ Rendering JSX 2️⃣ useMemo 3️⃣ useEffect (useCallback only runs if called) 💡 The lesson I learned Don’t just learn hooks. Learn when they run. Understanding execution order made debugging 10x easier for me. Now whenever something feels “weird” in React, I ask one question: 👉 Is this running during render or after render? Still learning React in human language. 🚀 #JavaScript #FrontendDevelopment #LearningInPublic #CleanCode #ReactJS #useEffect #useMemo #useCallback #FrontendDevelopment #LearningInPublic #JavaScript #WebDevelopment #DeveloperJourney #ReactHook

When I started using React with Tailwind, I thought the hard part would be JavaScript. It wasn’t. (Not honestly 😄) But, it was deciding whether mt-4 or mt-5 deserved to exist 😄 My components worked perfectly… but my UI kept asking for emotional support. Spacing issues. Alignment mysteries. The classic: “why does this look fine there but broken here?” React taught me how to break problems into components. Tailwind taught me how fast good UI is built when you stop fighting CSS. I really learned: • Smaller components = easier debugging • Utility classes look ugly at first, then save hours • Styling close to logic improves clarity • Consistent UI scales better than creative chaos Once I focused on structure over perfection, everything got smoother. Less tweaking pixels. More building features. (Though I still change gap-4 to gap-6 at least five times 😄) #ReactJS #TailwindCSS #FrontendDevelopment #LearningInPublic

🚫 JavaScript SPA frameworks aren’t always the answer. While building an MVP for a project recently, my first instinct was: “Let’s use React or Vue.” Not because the product truly needed them , but because they’re so popular that it feels like they’re the only correct way to build modern web apps. But I paused and asked: what does this product really need right now? For an MVP, speed, simplicity, and maintainability mattered more than complex client-side state management. So instead, I went with: ✅ Server-side rendering with Jinja ✅ Simple, clean UI with Bootstrap ✅ Minimal JavaScript And it was the right choice: • Faster development • Less overhead • Easier deployment & debugging • Perfectly aligned with the product stage No hydration issues, no duplicate API layers, no build tool headaches , just shipping. Lesson learned: 🧠 Popular doesn’t always mean best ⚙️ Choose the tool that solves the problem SPAs are powerful, but they’re not the default solution for every product, especially at the MVP stage. Curious to hear from other builders: have you ever not used React or Vue and was it the right call? #SoftwareEngineering #WebDevelopment #MVP #FastAPI #SSR #Backend

A while ago I was given a site to use to practise my Frontend Development skills (Frontend Practise: https://lnkd.in/dDUicDqS) So I vowed to build 1 page from the various levels given once a week, starting with Level 1. This week for my first page, I built WOW Studio Factor, a business-card style website focused purely on strengthening my JavaScript (ES6) fundamentals — an imitation of Oh.Studio. This demo was about translating UI behaviour into clear, maintainable logic — managing state through class toggling, event listeners, and conditional rendering. What I implemented in JavaScript: • Scroll-based reveal animations using the Intersection Observer API • Event listeners to control interactive UI behaviour • Conditional logic to determine what shows/hides dynamically • Dynamic class toggling to trigger image transforms and transitions • Modular, readable functions to keep behaviour structured Live demo: https://lnkd.in/dJq7Sjwy Inspired by: https://lnkd.in/dgRsgmFZ Desktop view only. #frontenddevelopment #javascript #webdevelopment #buildinpublic #womenintech #reactdeveloper #shecodes
