React Native's JSI Revolutionizes App Performance

Topic: Code Splitting in React – Ship Less JavaScript, Load Faster Apps 📦 Code Splitting in React – Why Loading Everything is a Bad Idea Most React apps bundle everything into one big file. 👉 More code = slower load = worse UX The smarter approach? Code Splitting 👇 🔹 What is Code Splitting? Load JavaScript only when it’s needed, instead of shipping everything upfront. 🔹 Basic Example const Dashboard = React.lazy(() => import("./Dashboard")); <Suspense fallback={<Loader />}> <Dashboard /> </Suspense> 👉 Component loads only when required 👉 Reduces initial bundle size 🔹 Why It Matters ✔ Faster initial load ✔ Better performance on slow networks ✔ Improved user experience ✔ Smaller bundle size 🔹 Where to Use It ✔ Routes (most common) ✔ Heavy components (charts, editors) ✔ Admin panels / dashboards ✔ Feature-based modules 💡 Real-World Insight Users don’t need your entire app at once. They only need what they see right now. 📌 Golden Rule Load less → faster app → happier users 📸 Daily React tips & visuals: 👉 https://lnkd.in/g7QgUPWX 💬 Have you implemented code splitting in your app yet? #React #ReactJS #CodeSplitting #FrontendPerformance #JavaScript #WebDevelopment #DeveloperLife

I genuinely thought converting a React web app to React Native would be easy....well, I was wrong. Initially, I thought it's mostly the copy-paste with minor tweaks. Spoiler: it's not. Here's what I realized: - No HTML -> everything becomes <View>, <Text> etc. - CSS doesn't work -> you work with StyleSheet. - No DOM -> whole rendering mindset changes. - Navigation is completely a different game. I probably wasted a good few hours thinking I can just "adapt" the UI. Big realization: 👉🏻You can reuse the logic, but not the UI. Now I am approaching it differently: Keeping business logic separated (and mostly reusable). Rebuilding the UI from scratch in native. If you are planning to do the same, don't "convert" - just re-architect the UI. Curious if others faced the same while switching to React Native?

Most developers underestimate the trade-offs between native modules and JavaScript in React Native, leading to hidden scaling bottlenecks you can avoid. When your app grows, relying too much on native modules can complicate debugging and slow down iteration. But pushing everything into JavaScript risks performance hits, especially around animations or heavy computations. In a recent project, I hit a wall when a third-party native module caused random crashes on Android. Moving a chunk of logic back into JS simplified testing and reduced those crashes. A practical approach? Keep UI and business logic in JavaScript for flexibility. Use native modules only for performance-critical parts—think camera, sensors, or custom animations. Also, document native bridges clearly. When teammates jump in, this saves hours untangling native-JS boundary issues. Balancing this isn’t just about performance; it’s about keeping your codebase maintainable as your team and features grow. How do you decide when to go native vs. JS?

When it comes to the React Native vs Flutter decision, I always ask "What will be harder to change in two years, business logic or UI?" React Native gives you access to a huge pool of JavaScript developers, so swapping someone out or moving web developers into mobile is quick and low-risk. Flutter gives you extremely reliable, polished UI, but finding the right developers takes more time. Even a single team change can slow down a project if you’re not prepared. You shouldn't treat this choice as a matter of preference, because in reality it’s a capacity and risk decision. I wrote a bit more about how I choose between these two technologies, and I also included KMP (expected from me 😅). Check the blog in the first comment!

I recently converted a React website into a Next.js application… and it changed how I think about React projects. At first, I thought it would just be a simple migration. But during the process, I realized something important. React is great for building UI. But Next.js solves many real-world problems automatically. While migrating the project, I noticed: ⚡ Faster page loads with built-in optimizations 🔎 Better SEO with server-side rendering 📂 Simple file-based routing 🖼️ Automatic image optimization The biggest takeaway for me was this: 👉 Modern React development is no longer just about React. Frameworks like Next.js are becoming the standard for production apps. This migration helped me understand how scalable React applications are actually built. Curious to know from other developers here: Do you prefer building with React only, or React + Next.js? #ReactJS #NextJS #FrontendDeveloper #WebDevelopment #JavaScript

Multi-page navigation in React is something most tutorials skip right over. So I built a project specifically around it. 16-web-editorial-layouts is a TypeScript + React application demonstrating production-ready multi-page navigation patterns — the kind of editorial layout structure you see in content-heavy platforms, but rarely in tutorial projects. Key technical choices: • TypeScript throughout for type-safe routing and component props • React client-side routing for navigation without full page reloads • Editorial layout patterns: hierarchical content, nested routes, persistent navigation • Clean separation between layout components and page content The insight: most React tutorials show you how to build a component. Very few show you how to structure a multi-page app so navigation feels native, state persists correctly, and layouts compose cleanly. This project fills that gap.

I tried to build a To-Do app in vanilla JS once. It was many lines of chaos. Today in React — it was 4 clean components. Day 42/100 — I just entered the React world, and I already can't imagine going back. Here's what I learned on Day 1 of React: 🔹 Components are just functions that return UI : That's it. No magic. Once this clicked, React went from intimidating to logical in minutes. 🔹 Class vs Function components : Class components are still out there ; you'll see them in older codebases. But function components are cleaner, simpler, and where React lives today. 🔹 Exporting components : Named export vs default export. Sounds trivial. Costs you some minutes the first time you get it wrong. Now I know why it matters. 🔹 Dynamic & Reusable components : Pass different props and get different output. One component, infinite uses. This is the moment vanilla JS started feeling like a lot of unnecessary work. The To-Do app I built today? Same app. Completely different experience. Vanilla JS: event listeners everywhere, DOM manipulation etc React: 4 components, each doing one job, each making sense on its own. If you've been putting off learning React — don't. The learning curve is real, but Day 1 already feels worth it. Day 42 done, 58 to go ! #100DaysOfCode #ReactJS #MERNStack #WebDevelopment #LearningInPublic #JavaScript #BuildInPublic

💥 React versus Vanilla JavaScript – the showdown that could save you weeks A: React is a component library that promises reusable UI blocks, a virtual DOM and a massive ecosystem. It shines when you need a single page app, real‑time updates and a team that lives in the node world. B: Vanilla JavaScript is the raw language that runs in every browser without a build step. It gives you full control, minimal payload and no lock‑in to a particular framework. My pick: Vanilla JavaScript for most client sites. Over a decade of building sites, I have delivered more than 150 projects where stripping out a framework cut load time by roughly thirty percent. When the requirement is a brochure, a landing page or a modest e‑commerce store, the extra bundle size of React rarely translates into measurable value. The simpler stack also means fewer security patches, easier hand‑off to designers and lower hosting costs. When you do need complex state management, real‑time dashboards or a mobile‑first progressive web app, React becomes a strategic advantage. The rule of thumb I follow is: if the user journey can be mapped in ten pages or less, stay with vanilla. If you are building a product that will evolve into dozens of interactive modules, React earns its keep. Your turn. Which side are you on?
