✨ A small personal win — but a big moment for me as a developer. For a long time, I wanted to build my own npm package. Nothing huge… just something useful — something I could proudly say: “I built this.” While working on multiple React projects, I kept fighting with the same issues: 1.messy fetch logic 2.repeated loading/error states 3.caching not behaving the way I wanted 4.retry logic 5.token refresh problems 6.too much boilerplate everywhere At some point I asked myself: “Why am I rewriting the same logic in every project? Let me turn this into a proper reusable hook.” So… I finally did it. 🚀 Introducing my first npm package: use-fetch-smart A lightweight React hook for smart data fetching — with caching, TTL, retries, token refresh, and instant cached responses. GitHub Repo: (in comments) npm: (in comments) 🔧 What it comes with ⚡ Smart caching + configurable TTL 🔁 Retry logic 🔐 Auto token refresh 🎯 Simple mutation API 🚀 Instant cached responses 🧽 Cleaner code, less boilerplate This is my first ever published package, and I know it’s not perfect. That’s actually why I’m sharing it. I want feedback. I want criticism. I want to know what breaks, what confuses you, what can be improved. Open-source is all about learning publicly — so here I am, starting small but starting somewhere. If you’re a React dev, I’d genuinely love if you try it out and share your thoughts. Even a single suggestion will help me grow and make this tool better. 🙏 Here’s to building, shipping, learning, and improving — one step at a time. 💛 #reactjs #npm #opensource #javascript #webdevelopment #frontend

Did you know React doesn't always batch your state updates? Yes, you heard it right. You must be familiar with batching — the process where React queues all state updates and then re-renders the component once with the final state values. For example: setCount(c => c + 1); setCount(c => c + 1); setCount(c => c + 1); Here React queues these updates like [c => c + 1, c => c + 1, c => c + 1], executes them together, and re-renders the component with the final value. So, you would see count = 3 directly on the screen after all updates are processed — not 1 or 2 in between. But sometimes batching doesn’t work like this. Let’s understand when it doesn’t. React batches state updates inside the same synchronous event handler. Notice the word — synchronous. That means React doesn’t batch state updates if asynchronous behavior appears in between. Getting confused? Let’s see an example: setCount(c => c + 1); await delay(2000); setCount(c => c + 1); setCount(c => c + 1); Here’s what happens: 1. React sees the first state update and notices an async boundary (await). 2. Instead of waiting for 2 seconds and then batching the next updates, it immediately re-renders the component after the first update. 3. When the delay is over, React batches the remaining two updates together and re-renders again. So the screen will first show count = 1, and then count = 3 — not directly count = 3. In short, React batches state updates only during synchronous execution. When async behavior enters, React commits the first update and starts fresh after the async task completes. #React #JavaScript #WebDevelopment #FrontendDevelopment #ReactJS

🚀 𝐃𝐚𝐲 𝟏 – 𝐍𝐨𝐝𝐞.𝐣𝐬 𝐄𝐯𝐞𝐧𝐭 𝐋𝐨𝐨𝐩 𝐃𝐞𝐞𝐩 𝐃𝐢𝐯𝐞 🔁 💚 Day 1 of my 15-Day Advanced Node.js Challenge! Today’s topic: The Event Loop in Node.js 🌀 The Event Loop is the heart of Node.js — it allows JavaScript to handle asynchronous operations efficiently, even though it runs on a single thread. Let’s test your Node.js knowledge 👇 ❓ 𝐐𝐮𝐞𝐬𝐭𝐢𝐨𝐧: 𝐖𝐡𝐞𝐧 𝐲𝐨𝐮 𝐫𝐮𝐧 𝐭𝐡𝐞 𝐜𝐨𝐝𝐞 𝐛𝐞𝐥𝐨𝐰, 𝐰𝐡𝐚𝐭 𝐝𝐨 𝐲𝐨𝐮 𝐭𝐡𝐢𝐧𝐤 𝐠𝐞𝐭𝐬 𝐩𝐫𝐢𝐧𝐭𝐞𝐝 𝐟𝐢𝐫𝐬𝐭? 𝐜𝐨𝐧𝐬𝐨𝐥𝐞.𝐥𝐨𝐠("𝐒𝐭𝐚𝐫𝐭"); 𝐬𝐞𝐭𝐓𝐢𝐦𝐞𝐨𝐮𝐭(() => 𝐜𝐨𝐧𝐬𝐨𝐥𝐞.𝐥𝐨𝐠("𝐓𝐢𝐦𝐞𝐨𝐮𝐭"), 𝟎); 𝐏𝐫𝐨𝐦𝐢𝐬𝐞.𝐫𝐞𝐬𝐨𝐥𝐯𝐞().𝐭𝐡𝐞𝐧(() => 𝐜𝐨𝐧𝐬𝐨𝐥𝐞.𝐥𝐨𝐠("𝐏𝐫𝐨𝐦𝐢𝐬𝐞")); 𝐜𝐨𝐧𝐬𝐨𝐥𝐞.𝐥𝐨𝐠("𝐄𝐧𝐝"); 🧠 Why? console.log() runs immediately (synchronous). setTimeout() goes to the macrotask queue. Promise.then() goes to the microtask queue, which runs before macrotasks. ⚙️ Key takeaway: The Event Loop first completes synchronous code, then runs microtasks, then moves to macrotasks (like timers). Understanding this helps write non-blocking, high-performance Node.js apps and makes debugging async code much easier! 💬 Your turn: Have you ever faced confusing async behavior in your Node.js code?

🧠 "When in doubt, log it out!" 🧩 Why Logging Is a Developer’s Silent Superpower Logs aren’t just for debugging — they’re your application’s black box recorder. When something goes wrong in production, structured logs can tell you what happened, where, and why — even when you’re not watching. Using tools like Winston in #NodeJS or #NestJS, you can: ✅ Track real-time application behavior ✅ Catch silent failures before they turn into major issues ✅ Measure performance and request times ✅ Maintain clean, leveled logs (info, warn, error) for better observability A well-implemented logging system turns guesswork into clarity — it’s the difference between finding the bug and hoping it shows itself. I use Winston logger across my Node.js and NestJS projects to maintain clarity, structure, and traceability throughout the entire request-response flow. It has become an essential part of my backend workflow for building reliable systems. #NodeJS #NestJS #BackendDevelopment #Winston #Logging #Winston #Debugging #CleanCode #ErrorHandling #JavaScript #ServerSide #Observability #ServerMonitoring #JavaScript #CodeTips #SoftwareDevelopment #SoftwareEngineering #Debugging #DevelopersJourney #DailyDevPost

⚛️ That moment when I finally understood useCallback() 😅 While working on a React project, I had a parent component that passed a function down to a child via props. Everything looked fine — until I noticed my child component was re-rendering every time I clicked anything, even if the data didn’t change! 🤯 After a few rounds of confusion (and console logs everywhere 😆), I discovered the culprit: React was re-creating the function on every render. That’s when I met my new best friend — useCallback() 💪 Here’s how it saved me 👇 ❌ Before: function Parent() { const [count, setCount] = useState(0); const handleClick = () => console.log("Clicked!"); return <Child onClick={handleClick} />; } ✅ After using useCallback(): function Parent() { const [count, setCount] = useState(0); const handleClick = useCallback(() => console.log("Clicked!"), []); return <Child onClick={handleClick} />; } 💡 Lesson learned: useCallback() tells React: 👉 “Hey, this function is the same unless dependencies change.” No more unnecessary re-renders. 🚀 React isn’t just about writing components — it’s about learning how to make them efficient! #ReactJS #useCallback #WebDevelopment #MERNStack #FrontendDeveloper #PerformanceOptimization #LearningByDoing #JavaScript #ReactHooks

🚀 𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐕𝐞𝐫𝐬𝐢𝐨𝐧𝐢𝐧𝐠 𝐢𝐧 𝐄𝐱𝐩𝐫𝐞𝐬𝐬 & 𝐍𝐏𝐌 : Today I learned something that many developers use every day… but rarely stop to understand — 𝐡𝐨𝐰 𝐯𝐞𝐫𝐬𝐢𝐨𝐧𝐢𝐧𝐠 𝐚𝐜𝐭𝐮𝐚𝐥𝐥𝐲 𝐰𝐨𝐫𝐤𝐬 in Node.js packages, especially Express. We’ve all seen version numbers like: 𝟒.𝟏𝟖.𝟐 But here’s the mindset shift 👇 Those numbers aren’t random. They communicate the risk of updating. 🎯 𝐒𝐞𝐦𝐚𝐧𝐭𝐢𝐜 𝐕𝐞𝐫𝐬𝐢𝐨𝐧𝐢𝐧𝐠 (𝐒𝐞𝐦𝐕𝐞𝐫) 𝐢𝐧 𝐏𝐥𝐚𝐢𝐧 𝐖𝐨𝐫𝐝𝐬 𝐌𝐀𝐉𝐎𝐑 . 𝐌𝐈𝐍𝐎𝐑 . 𝐏𝐀𝐓𝐂𝐇 𝐌𝐀𝐉𝐎𝐑 updates (e.g., 𝟒.𝐱.𝐱 → 𝟓.𝐱.𝐱) usually include breaking changes, so your code may need modifications. 𝐌𝐈𝐍𝐎𝐑 updates (e.g.,𝟒.𝟏𝟕.𝐱 → 𝟒.𝟏𝟖.𝐱) add new features but remain backward-compatible, so they’re generally safe. 𝐏𝐀𝐓𝐂𝐇updates (e.g., 𝟒.𝟏𝟖.𝟏 → 𝟒.𝟏𝟖.𝟐) include bug fixes, making them the safest to upgrade. Once I understood this, updating dependencies felt less scary — because now I know what I'm changing. 🪄 But here's the “hidden part” inside package.json Those small symbols at the start actually control how your project updates: "express": "~4.18.2" "express": "^4.18.2" ~ (𝐓𝐢𝐥𝐝𝐞) → 𝐎𝐧𝐥𝐲 𝐚𝐥𝐥𝐨𝐰𝐬 𝐏𝐀𝐓𝐂𝐇 𝐮𝐩𝐝𝐚𝐭𝐞𝐬→ keeps things stable ✅ ^ (𝐂𝐚𝐫𝐞𝐭) → 𝐀𝐥𝐥𝐨𝐰𝐬 𝐌𝐈𝐍𝐎𝐑 + 𝐏𝐀𝐓𝐂𝐇 𝐮𝐩𝐝𝐚𝐭𝐞𝐬→ more flexibility ⚡️ No symbol → Locks the version exactly → fully predictable 🔒 🧠 Quick Memory Hack ~ → “Only the safe stuff, please.” ^ → “Okay, I’m open to improvements… but don’t break things.” MAJOR updates → “Pause. Read. Think. Then update.” 😅 It’s a small concept with huge impact on long-term project health. #NodeJS #ExpressJS #BackendDevelopment #JavaScript #WebDevelopment #LearnInPublic #CodeEveryday

💻 𝐖𝐡𝐲 𝐝𝐨𝐞𝐬 𝐞𝐯𝐞𝐫𝐲𝐨𝐧𝐞 𝐮𝐬𝐞 𝘭𝘰𝘤𝘢𝘭𝘩𝘰𝘴𝘵:3000? Ever wondered why 𝘦𝘷𝘦𝘳𝘺 tutorial, project, and developer* seems to spin up their app on port 3000? 🤔 Let’s rewind a bit 👇 When Node.js came into the scene, developers started using frameworks like 𝐄𝐱𝐩𝐫𝐞𝐬𝐬 and later 𝐑𝐞𝐚𝐜𝐭. By default: • 𝐄𝐱𝐩𝐫𝐞𝐬𝐬 examples used port 3000 in docs 🧩 • 𝐑𝐞𝐚𝐜𝐭 (𝐜𝐫𝐞𝐚𝐭𝐞-𝐫𝐞𝐚𝐜𝐭-𝐚𝐩𝐩) also picked 3000 as its default dev server port ⚙️ • So it became the 𝘥𝘦 𝘧𝘢𝘤𝘵𝘰 “developer port” — simple, round, and always free. Other popular ones: • 8080 → for backend servers (used by Java/Apache) • 5000 → Flask (Python) • 5173 → Vite 🚀 • 4200 → Angular • 5500 → Live Server (VS Code) So, localhost:3000 became the 𝐡𝐨𝐦𝐞 𝐚𝐝𝐝𝐫𝐞𝐬𝐬 𝐨𝐟 𝐦𝐨𝐝𝐞𝐫𝐧 𝐰𝐞𝐛 𝐝𝐞𝐯𝐬 — a little piece of history that stuck around because it “just works.” 🧠 Fun fact: Ports range from 0–65535. Only ports below 1024 need admin rights — that’s why we start from 3000+!
