Avoid Fragile React Components with Reduced useEffect Usage

🎬 Movie Search Application (React) Developed a responsive movie search web application using React that allows users to search and explore movies in real time. The application integrates with an external movie API to fetch dynamic movie data such as title, poster, year. Implemented core React concepts including state management using hooks like useState and useEffect, along with event handling for search functionality. Added features like instant search, Enter key search, conditional rendering for error handling, and sorting movies by release year. Designed a clean and responsive UI using Flexbox and styled-components, including dark mode support for better user experience. 🔗 Live Demo https://lnkd.in/g2X-_Ken 💻 GitHub Repository https://lnkd.in/gczd-9bY #ReactJS #JavaScript #APIIntegration #RESTAPI #StyledComponents #ResponsiveDesign #FrontendDevelopment #WebDevelopment #MovieApp #FrontendProject #Coding #WebApp #Netlify #GitHub #OpenSource

React keeps two copies of your UI in memory and swaps them after every commit. That's double buffering. Part 2 goes deeper: priority lanes, where hooks actually live, the three sub-phases of the commit, and why React can pause rendering mid-tree.

⚛️ Old vs New: Handling Loading States the Smarter Way ❌ Before React 19, managing loading states meant dealing with isLoading flags, conditional renders, and custom spinners everywhere. Too much boilerplate… for something we use all the time. ✅ With React 19, the new <Loading /> component changes everything. It works hand-in-hand with Suspense to handle async UI automatically while your components fetch data. ✨ Key Features: 🔄 Automatic Loading State Handling — No more manual flags ⚙️ Built-in with Suspense — Seamless integration with async components 🎨 Customizable UI — Swap <Loading /> with your own spinner or skeleton 🧠 Cleaner Code, Less Re-renders — More declarative, more efficient #react #webdev #frontend #javascript #reactjs #coding #softwareengineering #devtips #ReactTips

Built a Snake Game using Vanilla JavaScript 🐍 Focused not just on functionality, but on writing clean and structured code: • Modular architecture (separation of concerns) • Game state management & smooth loop • High score persistence using localStorage • Start / Restart game flow This project helped me understand how even simple apps can be designed with scalability in mind. Would love feedback and suggestions 🙌 #javascript #webdevelopment #frontend #buildinpublic https://lnkd.in/gYhiMs6d

Everyone is experimenting with this new text engine. Here is what it actually looks like in a real UI. Text reflows around moving elements in real time. Smooth, no layout breaks. I built an interactive demo 👇 https://lnkd.in/ezshxrKB Built with Pretext by Cheng Lou: https://lnkd.in/eex7dUWH Would you use this in production? #Frontend #JavaScript #WebDev #BuildInPublic #Pretext

🚀 Improving Frontend Performance with Throttling & Debouncing One key realization while optimizing UI performance 👇 👉 Not all issues are about page load 👉 Many come from how frequently our code runs 🧠 The Problem Events like scroll 📜, resize 📏, and typing ⌨️ can fire hundreds of times per second This leads to: ❌ unnecessary work ❌ busy main thread ❌ poor responsiveness ⚙️ The Solution 🔹 Throttling 👉 Limit execution frequency 👉 e.g., run once every second 🔹 Debouncing 👉 Execute only after user stops 👉 e.g., search after typing stops 🎯 Key Difference 👉 Throttle = steady control 👉 Debounce = wait then act 📊 Why it matters 👉 Less work for browser 🧠 👉 Better responsiveness ⚡ 💡 “Performance is not just faster loading — it’s smarter execution.” #Frontend #JavaScript #WebPerformance #ReactJS #FrontendEngineering

🚀 Frontend Performance — Learning in Public Over the last couple of days, I explored Lighthouse-based performance analysis on a real application. Key learnings 👇 🧠 Main Thread Matters 👉 Browser runs on a single thread 👉 Heavy JS → slower interaction 🚦 Render-Blocking Resources 👉 CSS/JS can delay UI rendering ⛓️ Critical Request Chain 👉 Too many dependencies → slower loading 📊 Lighthouse Insight 👉 It’s not about score 👉 It’s about identifying root causes 🎯 Big takeaway: Performance = reduce work + remove blockers 📌 Next: Building a real-world performance audit report #Frontend #WebPerformance #JavaScript #ReactJS #SoftwareEngineering #LearnInPublic

🚀 Debounce vs Throttle in React (and when to use each) Handling user interactions efficiently is key to building performant applications — especially when dealing with frequent events like typing and scrolling. Here’s a simple breakdown: 🔹 Debounce • Delays execution until the user stops triggering the event • Best for: search inputs, API calls on typing 🔹 Throttle • Limits execution to once every fixed interval • Best for: scroll events, resize handlers ⚠️ Without control, frequent events can lead to: • Too many API calls • UI lag • Performance issues 📈 Results: • Reduced unnecessary API requests • Improved UI responsiveness • Better user experience 💡 Key takeaway: Use debounce when you want the final action, use throttle when you want continuous control.

We started naming our useEffect functions some time ago. Tiny change. Outsized impact. ❌ The "Mystery" Way useEffect(() => { fetch(`/api/users/${userId}`) .then(res => res.json()) .then(setUser); }, [userId]); Four effects like this in a component? You're reading every line just to understand what's happening. ✅ The "Self-Documenting" Way useEffect(function fetchUserProfile() { fetch(`/api/users/${userId}`) .then(res => res.json()) .then(setUser); }, [userId]); Now the name tells the story. You only open it when something breaks. But the real wins were unexpected: → If you can't name it without "and" — split it. "fetchUserAndLoadPermissions" is two effects in a trench coat. → Vague names expose effects that shouldn't exist. "updateStateBasedOnOtherState" isn't an effect. It's derived state. Move it out. → Stack traces go from useless to useful. "at (anonymous)" → no idea. "at fetchUserProfile" → straight to the bug. Want to enforce it across your team? "prefer-arrow-callback": ["error", { "allowNamedFunctions": true }] Zero new libraries. Zero new patterns. Just a name. So, start naming your effects. #React #JavaScript #FrontendDevelopment #WebDev
