World Explorer App Built with React.js and Vite

Most React apps are slow for one reason. Developers re-render everything. After working on multiple production apps, I’ve noticed the same mistakes again and again. Here are 3 simple ways to improve React performance instantly: 1️⃣ Memoize expensive components Use React.memo for components that receive the same props. 2️⃣ Avoid unnecessary state Too many states cause unnecessary re-renders. 3️⃣ Use lazy loading Load components only when needed using React.lazy. Small improvements like these can make a huge difference in production performance. A fast UI = better user experience.

Just published my first npm package: av-toastx I built av-toastx, a lightweight and customizable React toast notification library designed to make showing notifications in React apps simple and clean. 🔔 Features • Lightweight and fast • Simple React hook API • Multiple toast notifications support • Easy integration with any React project • Clean and customizable UI 🔗 Check it out on npm https://lnkd.in/gZcuk-29 This is my first step into building and publishing open-source tools for developers. I'm excited to keep improving it and adding more features. If you're building React apps and need a simple toast notification system, give it a try 🙌 Feedback, suggestions, and contributions are welcome! #opensource #reactjs #javascript #webdevelopment #npm #frontend #buildinpublic

⚛️ React vs Next.js React is powerful for building UI, but Next.js takes React further with features like routing, SSR, and better performance. If you're building modern scalable web apps, Next.js can save a lot of time. Which one do you prefer? 👇 #ReactJS #NextJS #WebDevelopment #FrontendDeveloper #JavaScript

"React performance: one trick that changed how I code" I used to re-render my entire app on every state change. Here's what I was missing... After years of building React apps, the single biggest performance win I found was understanding when components re-render — and stopping unnecessary ones dead in their tracks. The fix? Splitting state smartly. Keep fast-changing state close to where it's used, not at the top of your tree. 3 things I now do on every project: ✅ Use React.memo for pure components ✅ Move state down — don't lift it higher than needed ✅ Use useCallback/useMemo only when profiling shows it's needed (not by default) The last point is one most devs get wrong. Premature optimization with useMemo can actually slow things down. What's your go-to React performance tip? Drop it below 👇 #ReactJS #WebDevelopment #Frontend #JavaScript #SoftwareEngineering

Built a Todo List web application What this app does: • Allows users to add tasks with ease • Enables users to edit and update tasks dynamically • Lets users delete tasks they’ve completed Live demo: https://lnkd.in/dvHdrA5V #WebDevelopment #JavaScript #LearningJourney #Frontend

Most React apps slow down not because of bad code. But because of bad decisions made early. Here are 3 React mistakes I stopped making as a Full Stack Developer 👇 1. Re-rendering everything unnecessarily: If your component re-renders on every keystroke, your app feels broken. React.memo and useCallback exist for a reason. Use them deliberately. 2. Treating useEffect as a catch-all: useEffect is not where your logic lives. It's where your side effects live. Big difference. Most bugs I've debugged trace back to this exact confusion. 3. Ignoring performance until it's too late: A request waterfall adding 600ms of waiting time makes every other optimization pointless — it doesn't matter how optimized your useMemo calls are. Build fast from day one. Not as an afterthought. These aren't theory. These are lessons from building real projects with React — from client dashboards to AI-powered web apps.

🚀 Used React to build a To-Do List App. js Well recently, I created a simple yet useful ToDo List Application using React. js that covers fundamental React ideas such as useState, structure pointers, and event processing. 🔹 Features: • Add new tasks • Delete tasks • Clean and responsive UI Working on this project teaches me about React state management and functional components, which both helped me to get familiar with frontend development tools. 💻 GitHub Repository: https://lnkd.in/dWQWx8AU 🌐 Live Demo: https://lnkd.in/dhDS9VNR I am constantly working on projects to improve my frontend and React skills.

Your React app is slow. 🐌 5 mistakes killing your performance: 1️⃣ Skipping React.memo() Re-renders are silent killers. 2️⃣ Importing entire libraries ❌ import _ from 'lodash' ✅ import debounce from 'lodash/debounce' 3️⃣ No lazy loading ❌ Load everything upfront ✅ lazy(() => import('./HeavyComponent')) 4️⃣ Everything in global state Not every value needs Redux. 5️⃣ No pagination 1000+ items rendering = frozen UI. 💀 ──────────────── I fixed all 5 on a real app: → 30% faster load time → 10,000+ monthly users → Zero speed complaints 🚀 ──────────────── Save this 🔖 Which one are you guilty of? 👇 #ReactJS #NextJS #Frontend #Performance #JavaScript

A random thought I’ve had recently. Personally, mobile development feels more straightforward than web development. With mobile, it often feels like: Learn a framework → build your UI → connect to a backend (maybe Firebase or your own API) → ship your app. But the web ecosystem can feel overwhelming sometimes. On the web you start asking yourself questions like: Should I use React, Vue, Angular, Svelte, or something else? Next.js, Nuxt, Remix? SSR, CSR, SSG? Which state manager? Which bundler? Which styling solution? And that’s just the frontend 😅 Sometimes it can make you feel like you're doing something wrong if you focus on just one stack because new tools keep popping up. Meanwhile, mobile can feel more focused — pick your stack and build. Of course both have their own complexities, but the learning curve on the web sometimes feels longer because of the ecosystem. Maybe it’s just my experience. Mobile and Web developers — what do you think? Is web actually more complex, or does it just look that way because of the number of tools? 👇 Curious to hear your thoughts. #WebDevelopment #MobileDevelopment #DeveloperThoughts #ReactNative #Programming #DevCommunity

Most React apps start with a clean-looking structure: components/, hooks/, utils/, services/… …and then a few months later, every feature is scattered across 8 folders. That’s why I prefer feature-based folder structure for most real apps. Instead of organizing by file type, organize by business feature: features/auth features/products features/cart features/checkout Each feature can own its components, hooks, API calls, schemas, types, and tests. The biggest mistake to avoid: ❌ moving things to shared/ too early A lot of “shared” code is actually feature-coupled. Start inside the feature, then promote to shared/ only after real reuse appears. Rule of thumb: If a change touches one feature, your folder structure should make that obvious. #React #ReactJS #JavaScript #TypeScript #FrontendDevelopment #WebDevelopment #SoftwareArchitecture #FrontendArchitecture #CodeOrganization #CleanCode #SoftwareEngineering #DeveloperTips #ScalableApps #FolderStructure #ReactBestPractices
