Sometimes you’ll write 100 lines of code, and nothing works. Other times, one tiny line makes everything click. That’s the beauty (and frustration 😅) of being a developer. Every bug you fix, every error you debug, and every new concept you learn it’s all progress. You might not see it today, but you’re leveling up with every commit. 🚀 So the next time you feel stuck, remember: You’re not just writing code you are writing your story as a problem solver. 💡 #MotivationMonday #SoftwareEngineering #DevelopersJourney #WebDevelopment #ReactJS #NextJS #KeepLearning #CodeLife

𝑰𝒇 𝒀𝒐𝒖 𝑯𝒂𝒗𝒆 𝑬𝒗𝒆𝒓 𝑾𝒐𝒏𝒅𝒆𝒓𝒆𝒅 𝑾𝒉𝒚 𝒀𝒐𝒖𝒓 𝑹𝒆𝒂𝒄𝒕 𝑨𝒑𝒑 𝑲𝒆𝒆𝒑𝒔 𝑹𝒆-𝑹𝒆𝒏𝒅𝒆𝒓𝒊𝒏𝒈, 𝑹𝒆𝒂𝒅 𝑻𝒉𝒊𝒔... I used to live in the console. Every time something broke, I’d spam console.log() like my life depended on it. 😂 But here’s the truth, the console isn’t always your savior. My biggest debugging breakthrough came when I started using the React DevTools Profiler properly. That tool didn’t just show me errors… it showed me patterns. I could finally see what was re-rendering, why it was re-rendering, and how expensive each render was. And that’s when I realized most of my “mystery bugs” weren’t bugs at all, they were performance issues in disguise. Now, instead of aimlessly logging everything, I trace component behavior like a detective. It’s cleaner, faster, and honestly, more satisfying. If you haven’t explored the Profiler yet, you’re missing one of React’s best-kept secrets. I’ve shared a few of my experiments and findings on GitHub (https://lnkd.in/eP9nmTEw), it’s amazing how much smoother your debugging flow gets once you stop relying solely on the console.

“It works on my machine.” Famous last words. If you’re not testing your React components, you’re just hoping. If you are testing but your codebase still feels fragile, this blog post might help. We break down how to test React with Jest in a way that’s fast, clear, and doesn’t require rewiring your brain—or your project structure. Because confident code is testable code. #ReactJS #FrontendTesting #RheinwerkComputingBlog 👉 Read the quick-start guide: https://hubs.la/Q03R8Qlm0

🚀 Most Developers Use Vite… but Few Know Why It’s So Fast Everyone says “Vite is blazing fast.” But under the hood, it’s doing something surprisingly elegant — and very few engineers actually understand it. Here’s what’s really happening 👇 🧩 1. Dev Mode = No Bundling Traditional bundlers (like Webpack) pack your entire app before serving. Vite doesn’t. Instead, it uses native ES Modules (ESM) — a modern JavaScript feature that browsers already understand. So when you open your app, Vite serves each file directly to the browser. Change one file? Only that module reloads. ⚡ That’s why hot reload feels instant. 🛠️ 2. Build Mode = Rollup Optimization When you run vite build, the magic changes. Vite switches to Rollup, a battle-tested bundler that: Tree-shakes unused code Code-splits intelligently Minifies and optimizes output Result → production bundles are tiny and fast to load. ⚙️ 3. Node.js Is the Unsung Hero Vite itself runs on Node.js, which: Manages dependencies via npm Executes your dev server locally Powers tools like esbuild and Rollup under the hood You don’t ship Node to users — it just powers your tooling ecosystem. 🧠 In One Line > Vite = Node-powered dev server + Rollup-powered bundler + Browser-native ESM. That’s why it starts in milliseconds — and builds in seconds. 💬 Over to You What’s one “aha moment” you had while learning a modern tool like Vite, Next.js, or Astro?

⚛️ A real-life React situation that taught me a valuable lesson! I was fetching data from an API inside my React component. Everything worked fine at first — until I noticed something strange… the API was being called again and again 😅 My first thought: “Is my API haunted?” 👻 Turns out, it was just me forgetting to add the dependency array in useEffect. Here’s what I learned 👇 ❌ Wrong: useEffect(() => { fetchData(); }); ✅ Correct: useEffect(() => { fetchData(); }, []); The empty [] tells React to run the effect only once when the component mounts — not after every render. Lesson learned: sometimes one missing pair of brackets can cause infinite chaos 😆 Every mistake in React makes me understand it better — one re-render at a time! 🚀 #ReactJS #MERNStack #FrontendDevelopment #WebDevelopment #CodingJourney #LearningByDoing

🚀 𝐃𝐚𝐲 𝟐 – 𝐌𝐢𝐜𝐫𝐨𝐭𝐚𝐬𝐤𝐬 𝐯𝐬 𝐌𝐚𝐜𝐫𝐨𝐭𝐚𝐬𝐤𝐬 𝐢𝐧 𝐍𝐨𝐝𝐞.𝐣𝐬 ⚙️ 💚 Day 2 of my 15-Day Advanced Node.js Challenge! Yesterday, I explored how the Event Loop makes Node.js fast and non-blocking. Today, I went a step deeper — understanding the Microtask Queue and Macrotask Queue, the real reason behind how async code executes in Node.js 🔁 ❓ 𝐐𝐮𝐞𝐬𝐭𝐢𝐨𝐧: 𝐂𝐚𝐧 𝐲𝐨𝐮 𝐠𝐮𝐞𝐬𝐬 𝐭𝐡𝐞 𝐨𝐮𝐭𝐩𝐮𝐭 𝐨𝐟 𝐭𝐡𝐢𝐬 𝐜𝐨𝐝𝐞? 👇 𝐜𝐨𝐧𝐬𝐨𝐥𝐞.𝐥𝐨𝐠("𝐒𝐭𝐚𝐫𝐭"); 𝐬𝐞𝐭𝐓𝐢𝐦𝐞𝐨𝐮𝐭(() => 𝐜𝐨𝐧𝐬𝐨𝐥𝐞.𝐥𝐨𝐠("𝐌𝐚𝐜𝐫𝐨𝐭𝐚𝐬𝐤"), 𝟎); 𝐏𝐫𝐨𝐦𝐢𝐬𝐞.𝐫𝐞𝐬𝐨𝐥𝐯𝐞().𝐭𝐡𝐞𝐧(() => 𝐜𝐨𝐧𝐬𝐨𝐥𝐞.𝐥𝐨𝐠("𝐌𝐢𝐜𝐫𝐨𝐭𝐚𝐬𝐤")); 𝐜𝐨𝐧𝐬𝐨𝐥𝐞.𝐥𝐨𝐠("𝐄𝐧𝐝"); 🧠 𝐖𝐡𝐲? Node.js first executes all synchronous code (Start, End). Then it runs all Microtasks (Promises, process.nextTick). Finally, it executes Macrotasks (setTimeout, setImmediate). ⚙️ 𝐊𝐞𝐲 𝐭𝐚𝐤𝐞𝐚𝐰𝐚𝐲: Understanding the difference between microtasks and macrotasks is essential for debugging timing issues and writing efficient async logic. Master this, and you’ll never be confused by async behavior again 🚀 💬 𝐘𝐨𝐮𝐫 𝐓𝐮𝐫𝐧: Have you ever encountered async bugs due to the wrong task order? How did you solve them?

🚀 Today I learned about useContext and createContext hooks in React! These two hooks are powerful tools for managing state globally in a React application — without the need to pass props manually through every level of the component tree. Here’s what I learned 👇 createContext() helps create a global context that can store shared data. useContext() allows components to access that data directly, making code cleaner and more efficient. It’s especially useful for managing things like themes, authentication, and user location across components. Learning these hooks helped me understand how React handles state sharing and component communication more effectively. 💻 Excited to keep exploring React’s advanced features and improve my full stack development skills! ⚡ #ReactJS #WebDevelopment #Frontend #MERNStack #LearningJourney #JavaScript #ShebinThwalhath

I’ve been reviewing how long it takes for React state-management libraries to “take off” in terms of weekly downloads and growing adoption. In this post I’m sharing some data to say thank you to the devs who use or have tried use-s-react. Here are some comparisons: 1- @reduxjs/toolkit: Around 6 years old, more than 7 million weekly downloads, size ~13.8 kB gzipped, currently version 2.10.1. 2- zustand: About 7 years old, more than 13 million weekly downloads, version 5.0.8, size ~603 B gzipped. 3- jotai: Roughly 5 years old, over 2 million weekly downloads, version 2.15.1, size ~4.3 kB gzipped. 4- And now use-s-react: Version 2.4.0, size ~2.7 kB gzipped, no additional dependencies, very young at ~5 months, with ~271 weekly downloads so far. Thank you to everyone who is trying this tool. I’d love to hear from you — leave a comment or send me a message with what you’d like useS to include next, or any constructive feedback you’d like to share. #React #StateManagement #JavaScript #WebDevelopment #Frontend #ReactJS #OpenSource #Zustand #ReduxToolkit #Jotai #useS #ReactHooks #DevCommunity #Coding #Innovation #WebDev #Performance #NextJS #React19 #DeveloperTools

🚀 𝐑𝐞𝐚𝐜𝐭 𝐂𝐨𝐧𝐟 𝟐𝟎𝟐𝟓: 𝐋𝐞𝐬𝐬 𝐁𝐨𝐢𝐥𝐞𝐫𝐩𝐥𝐚𝐭𝐞, 𝐌𝐨𝐫𝐞 𝐏𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞, 𝐚𝐧𝐝 𝐅𝐫𝐞𝐞𝐝𝐨𝐦 React developers, if you missed the latest announcements, it's time to pay attention. React is shedding its historical baggage to focus purely on performance and developer sanity. Here's my take on the biggest updates that will change how we write code: 𝐓𝐡𝐞 𝐃𝐞𝐩𝐞𝐧𝐝𝐞𝐧𝐜𝐲 𝐀𝐫𝐫𝐚𝐲 𝐍𝐢𝐠𝐡𝐭𝐦𝐚𝐫𝐞 𝐢𝐬 𝐎𝐕𝐄𝐑! The new useEffectEvent hook is an absolute lifesaver. No more endless, unnecessary re-runs of effects just because a non-reactive function was in the dependency array. This is a massive step for avoiding bugs (and potential outages, a la Cloudflare's legendary 2024 episode! 😉). 𝐓𝐡𝐞 𝐂𝐨𝐦𝐩𝐢𝐥𝐞𝐫 𝐖𝐞 𝐃𝐞𝐬𝐞𝐫𝐯𝐞: React Compiler 1.0 is stable! This is the real star. We can finally start retiring our manually scattered useMemo and useCallback hooks, which let's be honest, often did more harm than good or were simply tedious boilerplate. Hello, automatic performance optimization. 𝐈𝐧𝐭𝐞𝐥𝐥𝐢𝐠𝐞𝐧𝐭 𝐔𝐈 𝐒𝐭𝐚𝐭𝐞 𝐌𝐚𝐧𝐚𝐠𝐞𝐦𝐞𝐧𝐭: The Activity component gives us a native, smart way to hide/show elements. It maintains state and intelligently de-prioritizes work for hidden components—a great performance boost over just using CSS. 𝐀 𝐍𝐞𝐰 𝐄𝐫𝐚 𝐨𝐟 𝐈𝐧𝐝𝐞𝐩𝐞𝐧𝐝𝐞𝐧𝐜𝐞: The transition of React and React Native to the React Foundation, separate from Meta, is crucial for long-term governance and community trust. A great move for the ecosystem! 𝐓𝐡𝐞 𝐅𝐮𝐭𝐮𝐫𝐞 𝐢𝐬 𝐀𝐈-𝐅𝐫𝐢𝐞𝐧𝐝𝐥𝐲: A quick nod to Remix 3—a simpler, web-fundamentals-first framework that the authors of React Router are building, specifically citing an "AI-friendly" approach. The competition is good for all of us! React is moving from a framework that needed constant developer hand-holding (manual memoization) to one that just works fast. Get ready to ditch that boilerplate and write cleaner, more intuitive code.
