Optimize FlatList for Fast React Native Apps

🚀 Just built a full-featured Todo App in React! ✅ Add, Edit & Update tasks ✅ Mark tasks as Complete / Pending ✅ Filter by All / Completed / Pending ✅ Persistent data with LocalStorage ✅ Clean UI with counters & interactive buttons This project helped me strengthen my React skills, state management, and UI handling. 🌟 Source Code: 👉https://lnkd.in/dSRsWdeM Muhammad Osama Saylani Mass I.T Training (S.M.I.T) #ReactJS #WebDevelopment #JavaScript #FrontendDevelopment #CodingJourney #ProjectShowcase #TodoApp

I remember struggling with forms in React… trying different libraries, fixing validation issues, and optimizing performance. ⚛️ That’s when I explored Formik vs React Hook Form. Formik felt simple and quick to start. But as projects grew, I started leaning more towards React Hook Form for better performance and flexibility. Now my go-to depends on the project: • Formik → quick and lightweight setups • React Hook Form → scalable & performance-focused apps There’s no “one perfect choice” - it’s about what fits your use case. Which one do you prefer for your React projects? 👇 #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #ReactDevelopers

Built a small Background Changer app while learning React. Simple idea, but a good exercise for understanding components and data flow. Instead of hardcoding colors, I created a reusable Button component and used .map() to render them dynamically with props. Also experimented with Tailwind CSS for smooth hover effects and a small magical text touch. ✨ Step by step, React concepts are starting to click. Click carefully… It’s magic. 😉 #reactjs #webdevelopment #chaiaurcode #tailwindcss

## DAY 23 — React To-Do App (Rebuild) Day 23/30: I rebuilt my Day 20 To-Do List in React. Same features. Completely different experience. Vanilla JS version: 200+ lines of DOM manipulation, querySelector everywhere, manual state tracking. React version: clean components, useState for state, props for data flow, and the UI just updates when data changes. No more document.getElementById. I finally understand why React exists. Not because someone explained it — because I built the same thing twice and felt the difference. The code is cleaner, more organized, and I could add new features in minutes instead of hours. 🔗 Live: https://lnkd.in/gWYqnKGu 🔗 Code: https://lnkd.in/g3S9JDnt #30DaysOfCode #React #JavaScript #WebDevelopment #BuildInPublic #WomenInTech

⚛️ React Concept: Lazy Loading Components As React applications grow, the bundle size also grows. Loading everything at once can slow down the initial page load. That’s where Lazy Loading helps. 🧠 What Lazy Loading does Instead of loading all components upfront, React can load components only when they are needed. This technique is called code splitting. 🚀 Why it matters ⚡ Faster initial load 📦 Smaller bundle size 🎯 Better performance for large applications 💡 Real-world example Pages like: 📊 Dashboard ⚙️ Settings 🛠️ Admin Panel don’t need to load until the user navigates to them. Lazy loading ensures these parts of the app are downloaded only when required. 🧠 Simple idea Load only what the user needs now, and fetch the rest when it’s needed. #React #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #CodeSplitting #PerformanceOptimization #LearnInPublic #SoftwareEngineering

Passing Parameters in React Native Stack Navigation Sometimes we need to send data from one screen to another, like user ID, name, or product details. In React Native, this can be done easily using navigation.navigate() and route.params. ✔ Pass data while navigating ✔ Receive data in the next screen ✔ Useful for dynamic screens This simple feature helps make apps more interactive and flexible. How often do you pass parameters between screens in your apps? 🤔 #ReactNative #MobileDevelopment #JavaScript #CodingTips

🚀 New YouTube Video: Build a React Todo App with Context API & Tailwind CSS Just published a new video where I walk through building a complete React Todo App using Context API and Tailwind CSS. In this tutorial, I cover: • Managing global state with Context API • Avoiding prop drilling in React • Implementing add, edit, and delete features • Persisting todos with localStorage • Structuring React components for scalable projects If you're learning React or frontend development, this project is a great hands-on way to understand state management. 💻 Source Code: https://lnkd.in/greweQef 🌐 Live Demo: https://lnkd.in/gMYPDP4s 🎥 Watch the full video: https://lnkd.in/g79buWqw Let me know your thoughts and feedback! #ReactJS #ContextAPI #TailwindCSS #WebDevelopment #FrontendDevelopment #JavaScript #ReactProject

React Native apps run in two completely different worlds. So how do they actually communicate? Understanding this communication is key to understanding why the New React Native Architecture exists. I tried to break this down visually in this post. Save this post if you're learning React Native internals. In the next post, we’ll explore about JSI. #ReactNative #ReactNativeDev #MobileDevelopment #SoftwareArchitecture #JavaScript #DeveloperCommunity

React is just not about useState👀 My App.jsx had become a mess — multiple useEffects, auth checks, socket connections, loading states… everything in one place. It worked, but reading it felt like debugging a jungle 😅 That’s when it hit me — this is exactly where custom hooks shine. Instead of stuffing all logic inside components, we can extract it into reusable hooks like: useAuth() → handles user + login state useSocket() → manages connection & events useLoading() → controls loaders Basically turning this 👇 👉 one giant useEffect into this 👇 👉 clean, readable, modular logic What I love about custom hooks is: They clean up components They remove duplication And they make your code feel more like building blocks than chaos Also an underrated point: 👉 Custom hooks don’t share state, they just share logic. (React) That means every component still stays independent, which is exactly what we want. Still learning, but this small shift already made my code 10x better. If you’re writing long useEffects… that’s probably your signal to create a hook ⚡ #ReactJS #FrontendDevelopment #WebDevelopment #CodingJourney #JavaScript
