Code Splitting Boosts App Load Speed

single Flutter widget improved my app performance. While working on a project with a complex ListView, I started noticing something frustrating - The Ul was lagging even though only a small part of the Screen was changing. After spending time debugging the issue, the fix turned out to be surprisingly simple: "RepaintBoundary" Flutter normally repaints a large part of the widget tree during rebuilds. But "RepaintBoundary" tells Flutter: "Only repaint this specific widget, not everything around it."> So the repaint work becomnes isolated and much more efficient. Example: Before ListView. builder( itemBuilder: (context, index) { return HeavyWidget(index); Frame drops while scrolling.

Think a smaller bundle automatically means a faster React app? Think again. The myth: shrink everything into one bundle and call it a day. The reality: smart code‑splitting delivers faster first paint and lower bandwidth without sacrificing functionality. How to split effectively: Use React.lazy() and for component‑level lazy loading. Leverage dynamic import() for on‑demand modules. Create route‑based chunks with React Router and webpack’s splitChunks. Extract vendor libraries into their own chunk. Analyze sizes with webpack‑bundle‑analyzer or source‑map explorer. Set sensible cache groups to avoid over‑splitting. Result: users download only what they need, when they need it, and your app feels snappy. Which splitting technique has made the biggest difference for you?

Flutter is a powerful and popular framework for building cross-platform applications. And if you want to learn its ins and outs, check out this handbook Anthony wrote. In it, he teaches you how to build scalable and performant Flutter apps & covers state management, widgets, async patterns, and lots more. https://lnkd.in/gxChjHia

⚠️ Claude Code doesn't surface usage data inline. To check your 5-hour session limit, weekly usage, or billing, you have to switch to the web app. No app switching while you're deep in a task doesn't sound like much until you're doing it ten times a day. 👉 So I wrote a bash script that puts all of it directly in the status line:  → 5-hour session limit with countdown when you're close  → 7-day weekly usage  → Extra spend vs. monthly cap  → Context window usage  → Git branch + uncommitted changes No manual token setup. No Node.js. No Rust. Just tell Claude Code to install it (prompt in the comment)  #ClaudeCode #ProductManagement #DeveloperTools #OpenSource #Anthropic

One buggy component shouldn’t crash your whole Vue app! 🚨 Error Boundary components catch errors in individual components so your app stays resilient. 💡 Display friendly fallback UIs 🛠️ Let users retry with a “Try Again” button 🎯 Keep your code maintainable and predictable Whether it’s a complex chart, third-party widget, or lazy-loaded component, error boundaries are your safety net. Learn how to implement them and master error handling in Vue 👉https://lnkd.in/dsDetn7q

🚀 React Hands-on Series #1 🧠 Problem Statement: Build a Todo App 🎯 Your Task: Build a fully functional Todo App with the following features: ✅ Add a new todo ✅ Delete a todo ✅ Mark a todo as Complete ✅ Filter todos (All / Completed / Pending) ✅ Display total tasks count dynamically

Small Flutter habit that improves performance: Use const widgets whenever possible. const Text("Hello Flutter") Why it matters: ✔ Reduces unnecessary rebuilds ✔ Improves rendering performance ✔ Makes widgets immutable Small optimizations add up in production apps. #Flutter #Performance #CleanCode

Keeping Vue components small and focused makes your code easier to read, test, and maintain. 💡 Instead of cramming everything into one big component, break it into smaller pieces: 🖥️ `UserHeader` 📊 `UserStats` 📜 `RecentActivity` Each handles a single responsibility, making your app cleaner and more predictable.

𝗧𝗵𝗲 𝗕𝗮𝘀𝗶𝗰𝘀 𝗢𝗳 𝗦𝘁𝗮𝘁𝗲 𝗠𝗮𝗻𝗮𝗴𝗲𝗺𝗲𝗻𝘁 𝗜𝗻 𝗥𝗲𝗮𝗰𝘁 You're building a React app. You need to manage state. State management is about structuring your app and handling states across components. You deal with two categories of state: - Local State: a state that only one component needs - Global State: a state that multiple components need For example, in a todo list app, the search bar state is local. The list of todo items is global state. If several components rely on the same state, move that state into a common parent component and pass it down as props. Remember to place state where it logically belongs. Keep related logic close to the component that needs it. Avoid unnecessary states in your main app file. If passing props down multiple layers becomes too much, use the Context API. External libraries like Zustand or Redux exist to solve problems in larger apps. Use them when your app becomes difficult to manage or you face performance bottlenecks. For many apps, Context and useState are enough. Source: https://lnkd.in/g-3rUUWG
