How to use conditional rendering in React

A recent realization while building with Next.js — I initially went with Static Site Generation (SSG) thinking it would be a perfect mix of performance and simplicity. But once I introduced dynamic routes like "[id]", I hit the limits of static export pretty quickly. That’s when it clicked — static export and dynamic behavior just don’t mix well. Next.js shines when it has a server to lean on — for data fetching, incremental builds, or API routes. But if you’re deploying purely static files, something like Vite + React Router might be a better fit. Not really a mistake — more of a reminder: Always choose your framework based on how and where you plan to host. These small realizations shape your intuition over time — and honestly, that’s the best part of building things. 🚀 #Nextjs #Reactjs #WebDevelopment #Frontend #JavaScript #LearningByBuilding #DeveloperJourney #Vite #StaticSiteGeneration #DevThoughts

⚡ Build Your Own React Hook Library — Organize, Reuse, Scale Most React projects eventually become a mess of duplicated logic across multiple components. But once you learn to structure and export your hooks properly — everything changes. Here’s what having a Hook Library gives you: ✅ Cleaner code ✅ No duplicated logic ✅ Shorter imports ✅ Easier onboarding for teammates Write code once → reuse forever. ♻️ Have you built your own internal hook library yet? #React #ReactJS #ReactHooks #Frontend #WebDevelopment #CleanCode #DeveloperExperience #JavaScript #CustomHooks #Performance #CodingTips

Check out this ⚛️ React tip from Thales Domingues 🚀 Keep your React code DRY! When your code starts to repeat itself, that’s usually a sign it’s time to refactor. The DRY principle (Don’t Repeat Yourself) helps you build cleaner, more scalable, and maintainable React applications. 🧠 Think reusable components, custom hooks, and centralized utilities — your future self (and your teammates) will thank you. How do you make sure your React code stays DRY? 💬👇 #React #JavaScript #CleanCode #Frontend #WebDevelopment #SoftwareEngineering #DRY

🚀 React Fundamentals – Day 1 I’ve started a new React Fundamentals guide series where I’ll be walking through the core concepts of React — from setup to key principles. In Day 1, I covered: ✅ Integrating React into a Project ✅ Understanding CORS ✅ Introduction to CDN ✅ Rendering in React ✅ Working with Props If you’re getting started with React or want to revisit the basics, check out the full article on Confluence 👇 🔗 https://lnkd.in/gEChKH7S #React #WebDevelopment #Frontend #JavaScript #LearningReact #ReactJS

🔥 3 React tips that leveled up my code: Use functional components, keep components small, and leverage custom hooks. Small changes, huge improvements! #ReactJS #FrontendTips #CleanCode

Sometimes, your React component re-renders even when props haven’t changed. That’s where React.memo helps. It wraps a component and re-renders it only if the props actually change. This can make a big difference in complex UIs tables, charts, or lists. But don’t overuse it. Adding React.memo everywhere might even slow things down due to prop comparison overhead. Use it where re-renders are expensive. Do you use React.memo in your components regularly? #react #frontend #webdev #javascript

I recently made a small optimization in my React project — and it improved the load time by almost 30%! It all came down to: ✅ Replacing heavy 3rd-party libraries with lighter ones ✅ Using React.lazy and Suspense for code splitting ✅ Loading only what’s needed (dynamic imports) Such a tiny tweak made a noticeable difference in performance — both in Lighthouse scores and real-user experience. Sometimes, the biggest wins come from the smallest changes 💡 Have you made a simple tweak that gave you big results?

💭 Thinking in React: Local vs Global State Managing state efficiently is one of the most important parts of building scalable React applications. In this post, I’ve broken down the thought process behind deciding when to use local state and when to go global — along with a simple decision flow. 🔹 Local State – Used for component-specific data (like form inputs, modals, or toggles). 🔹 Global State – Used when multiple components need to share or synchronize data (like user authentication, theme, or cart data). Understanding this difference helps keep your code clean, maintainable, and performant. Check out the slides to see how you can think in React more strategically while managing state. 🚀 #ReactJS #WebDevelopment #Frontend #JavaScript #ReactState #StateManagement #LearningInPublic

The End of forwardRef Hell? 😇 React 19 Simplifies Refs Forever. Every developer knows the pain of trying to pass a ref through a component chain. You run into the classic error, realize you need to use the dreaded forwardRef(), and then restructure your entire file. It's boilerplate that solves a framework limitation. In React 19, this friction is gone. ref is now automatically available as a standard prop on all components, just like key. This single change makes component composition smoother, simplifies HOCs (Higher-Order Components), and eliminates a huge chunk of unnecessary boilerplate. It's a massive quality-of-life win for building component libraries. What other piece of React boilerplate are you hoping to see eliminated next? 👇 #React19 #ReactHooks #Frontend #JavaScript #Refactoring #CodeCleanliness

⚛️ Batched State Updates Ever wondered why multiple setState calls don’t cause multiple re-renders? That’s React’s batched state updates — a mechanism that groups several state changes into a single render cycle. 💡 Why it matters: Prevents unnecessary renders. Boosts performance. Keeps UI consistent during rapid state changes. ⚠️ Watch out: Batched updates mean setState is asynchronous — your updated value isn’t available immediately after calling it. Use functional updates (setCount(prev => prev + 1)) to stay safe. Mastering React means understanding not just what re-renders — but when and why it does. #ReactJS #Frontend #Performance #JavaScript #WebDevelopment
