⚛️ Old vs New: Handling Loading States the Smarter Way ❌ Before React 19, managing loading states meant dealing with isLoading flags, conditional renders, and custom spinners everywhere. Too much boilerplate… for something we use all the time. ✅ With React 19, the new <Loading /> component changes everything. It works hand-in-hand with Suspense to handle async UI automatically while your components fetch data. ✨ Key Features: 🔄 Automatic Loading State Handling — No more manual flags ⚙️ Built-in with Suspense — Seamless integration with async components 🎨 Customizable UI — Swap <Loading /> with your own spinner or skeleton 🧠 Cleaner Code, Less Re-renders — More declarative, more efficient #react #webdev #frontend #javascript #reactjs #coding #softwareengineering #devtips #ReactTips

I read a React codebase's sidebar component top to bottom. Twelve files, one SaaS suite, zero magic. The whole thing fits in a carousel. ↓ What you'll see, file by file: → Composition by convention — numbered folder prefixes (_1/_2/_3) that enforce visual order. → Union types + Record<K,V> — the compiler refuses to build until every variant has a label. → Design tokens as data — avatar sizes, paddings, border widths all in one typed object. No JSX ternaries. → CustomSelect — one component, three+ use cases. Base styles locked, overrides via cn(). → Triple memoization on Context — useCallback on setters, useMemo on the value, fully enumerated deps. No accidental re-renders. → Animation variants as objects — Framer Motion configs live outside the component. Testable, swappable, versioned. → Exit faster than enter — 120ms out, 180ms in. Asymmetric durations feel right because they match human attention. → Effects are contracts — polling pauses when the tab is hidden. Listeners always removed in cleanup. Every slide is real code from a production SaaS frontend. Not a tutorial, not a toy example. Rust on a chip was post #01. React in the browser is post #02. Same ethos: small files, sharp decisions, no magic. Repo link in the first comment. #ReactJS #TypeScript #Frontend #NextJS

Exploring #ArrowJS , a minimalist approach to modern frontend development ArrowJS is an experimental #JavaScript library for building reactive user interfaces using native JS, without the overhead of traditional frameworks. It challenges the idea that complex tooling is required to build powerful UIs. Key highlights: • ⚡ Ultra-lightweight (~3KB) with zero dependencies • 🧩 No build step, no virtual DOM, no custom templating language • 🔄 Reactive by choice — not by default • 🧠 Leverages modern JavaScript features like template literals, modules, and proxies • 🚀 Fast and simple, with a focus on developer ergonomics The core idea? JavaScript itself has evolved enough that we don’t always need heavy frameworks to create dynamic, performant applications. ArrowJS embraces that philosophy with a “less is more” approach. Worth checking out if you’re interested in lightweight alternatives to React/Vue or exploring new patterns in frontend architecture. #JavaScript #WebDevelopment #Frontend #SoftwareEngineering #Programming #WebDev #DeveloperTools #React #Vue

Built a Snake Game using Vanilla JavaScript 🐍 Focused not just on functionality, but on writing clean and structured code: • Modular architecture (separation of concerns) • Game state management & smooth loop • High score persistence using localStorage • Start / Restart game flow This project helped me understand how even simple apps can be designed with scalability in mind. Would love feedback and suggestions 🙌 #javascript #webdevelopment #frontend #buildinpublic https://lnkd.in/gYhiMs6d

💡 Lifting State Up in React — One of the Most Important Concepts When working with React, one challenge we often face is sharing state between multiple components. That’s where lifting state up comes in. 👉 Instead of managing state in multiple child components, we move (or “lift”) the state to their closest common parent. Why does this matter? ✔ Ensures a single source of truth ✔ Keeps UI consistent and predictable ✔ Makes components more reusable and easier to debug 📌 Example: If two components need to reflect the same data (like a form input and a preview), managing state separately can lead to inconsistencies. By lifting the state to a parent component and passing it down via props, both stay in sync. ⚡ Pro Tip: Lifting state up is powerful, but don’t overdo it. For deeply nested components or complex state sharing, consider tools like Context API or state management libraries. Clean architecture isn’t just about writing code — it’s about placing state in the right place. #React #FrontendDevelopment #JavaScript #WebDevelopment #ReactJS #SoftwareEngineering

🧵 Day 4 of 40 — React System Design Series useEffect causes more bugs than any other hook in React. Infinite loops. Stale data. Memory leaks. Missing cleanups. I've written all of those bugs. And they all came from one thing: learning useEffect as a lifecycle method instead of what it actually is. useEffect is a synchronisation tool — not componentDidMount. Today I broke down: → The mental model that changes everything (sync, not lifecycle) → The 3 forms of useEffect and when to use each → AbortController for fetch cleanup (and why it matters) → Stale closures and the ESLint rule that catches them automatically → When NOT to use useEffect (this one surprises people) Full breakdown with real TypeScript code 👇 https://lnkd.in/g5rcJ7qJ #ReactJS #SystemDesign #Frontend #LearningInPublic #WebDevelopment

🚀 Just checked out Vite 8 + AI… and honestly, it feels crazy fast. At first, I used to think Vite was just another dev server. But after exploring it more, it’s actually way more powerful. Here are a few things I noticed 👇 ⚡ Builds feel much faster — even big projects start quickly 🧠 Dependency handling seems smoother (less random issues 😅) 📦 SSR support is better now, which is pretty cool 🔌 Plugins are improving and easier to work with 🛠️ Overall dev experience feels cleaner and less frustrating 💻 One thing I really liked: Frontend errors now show directly in the VS Code terminal (Browser Forward Console). Earlier I had to check the browser console, but now everything is in one place — makes debugging much easier. 📂 Also, TypeScript path aliases are supported better now. No more messy imports like ../../components — cleaner and easier to manage. 💭 What I liked the most: Hot reload + fast builds = less waiting, more coding. Still exploring it, but Vite 8 definitely feels like a solid upgrade. If you're working with React, Vue, or modern JS — you might want to give it a try. Has anyone else tried Vite 8 yet? What do you think? #Vite #Frontend #JavaScript #WebDev #React #Vue

I hate React memoization. Not because memoization is bad. Because developers keep using it to solve problems they have not even identified. useMemo on cheap calculations. useCallback on everything that moves. memo wrapped around components that still rerender anyway. No profiling. No bottleneck. No real reason. Just extra complexity in the name of “performance.” Most of the time, the real issue is not that React needs more memoization. It is that the component tree, state boundaries, or data flow were designed badly in the first place. At this point, memoization is not performance work. It is perfume on architecture problems. #react #frontend #javascript #performance #webdevelopment

It is possible to install the package https://lnkd.in/dHtbjDK3 specifically to avoid having to manually add dozens, if not hundreds, of memoizations, which would otherwise burden the developer and reduce code readability. - Hook soup: components with many custom hooks - it is able to manage and optimize even in these cases. In general, it is important that the code follows the Rules of React in order to work properly. It is available and optimized for version 19, but it can also be used with versions 17 and 18, provided that an additional polyfill plugin is installed: react-compiler-runtime. Although supported, the React team states that the compiler works best with React 19, since it includes native optimizations that the external runtime has to emulate. Additionally, it is possible to install react-scan to visually identify automatically memoized components, marked with a ✨ icon.
