Just shared a new article on Medium about React Custom Hooks! 🚀 As React developers, we often struggle with bloated components. Custom Hooks are a game-changer for extracting reusable logic and keeping our codebase DRY (Don't Repeat Yourself). In this article, I cover: ✅ What Custom Hooks are ✅ Building a reusable useFetch hook ✅ Best practices for clean code Check it out here: https://lnkd.in/g2Pp46As #ReactJS #WebDevelopment #JavaScript #Programming #Frontend #CodingTips

🚨 𝐄𝐒𝟔 𝐌𝐨𝐝𝐮𝐥𝐞𝐬 𝐯𝐬 𝐂𝐨𝐦𝐦𝐨𝐧𝐉𝐒 𝐜𝐨𝐧𝐟𝐮𝐬𝐢𝐨𝐧 𝐏𝐫𝐨𝐛𝐥𝐞𝐦𝐬 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫𝐬 𝐅𝐚𝐜𝐞 👀 If you're working with Node.js, you've probably run into this confusion: Why does this work sometimes… import express from "express" …but other times only this works? 😑 const express = require("express") here is what dealing with ES Modules vs CommonJS looks like👇 1. "Cannot use import statement outside a module" Why it happens Node.js defaults to CommonJS, so "import" won't work unless you tell Node to use ES Modules. So how do you fix this? You simply add this to your "package.json": 👇 "type": "module" 2. "require is not defined" This happens when you're using: "type": "module" Now Node expects ES Modules, so "require()" won't work. How do we solve this? You use: import express from "express" 3. Mixing CommonJS and ES Modules This is one of the biggest headaches: const something = require("./file.js") But the file exports using: export default something Boom 💥🤯 errors everywhere. 4. File Extension Problems (.js vs .mjs) ES Modules often require: import file from "./file.js" Even when you're already inside ".js" Many developers forget this and get errors. 5. Default vs Named Export Confusion export default function (default export) Is different from: export const function (named exports) And importing them incorrectly causes: ❌ undefined errors ❌ runtime crashes ❌ silent bugs So when do you use Each? Use CommonJS When: - Working with older Node.js projects - Using older libraries - Working with legacy codebases Use ES Modules When: - Building modern apps - Using React / Vite / Next.js - Writing new backend projects This helps you to: ✅ Debug faster ✅ Work with legacy code ✅ Build modern backend apps ✅ Avoid production bugs Some developers don't struggle with backend logic… They struggle with module confusion. Once you master this, Node.js becomes much easier. Are you using CommonJS or ES Modules right now? #JavaScript #CodingTips #WebDevelopment #Programming #SoftwareEngineering #DevTips #nodejs #backend #fullstack

React is finally getting a built-in useForm hook… and it’s a big shift Right now, every project: 🔹 Formik 🔹 React Hook Form 🔹 Zod + custom logic More setup. More dependencies. More bundle size. Now React is bringing it into core 🔹 Validation 🔹 Form state 🔹 Submission 🔹 Error handling All built-in. No extra libraries. We’ve seen this pattern before: → Data fetching → now simpler patterns → Routing → built into frameworks → Memoization → handled by React Compiler React continues to absorb what we used to depend on. That’s not a problem - that’s growth What this means now: 🔹 Don’t over-engineer forms 🔹 Keep it simple 🔹 Focus on fundamentals (controlled vs uncontrolled) Libraries change. Basics don’t. Still using Formik or React Hook Form? 👇 #ReactJS #WebDevelopment #FullStackDeveloper #Frontend #JavaScript

✨React is no longer just a library… it’s an entire ecosystem. There was a time when learning React meant understanding components, props, and state. Today? That’s just the beginning. ⸻ 💡 Modern React development is about choosing the right tools from its ecosystem: ⚡ Next.js — For production-ready apps SSR, routing, performance — all handled seamlessly. 🧠 State Management (Redux / Zustand) — Manage complex state with clarity and scalability. 📡 React Query / TanStack Query — Fetching, caching, syncing server data — made simple. ⸻ ⚠️ But here’s where many developers get stuck: Trying to learn everything at once. ⸻ 🔥 The truth is: You don’t need every tool. You need the right tool for your use case. Because: ✔ Over-engineering slows you down ✔ Simplicity scales better ✔ Clarity beats complexity ⸻ 💭 A better approach: Start with core React → Add tools as problems grow → Learn by building real projects ⸻ ⚡ Remember: Great developers don’t just know tools… They know when NOT to use them. ⸻ 💬 Question: What’s your go-to React library right now — and why? ⸻ 📌 Save this post if you’re exploring the React ecosystem. #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #NextJS #Redux #Zustand #ReactQuery #Programming #Developers #SoftwareEngineering #TechStack #LearnToCode #BuildInPublic

Ever paused for a second and thought about this… We build entire worlds with code — using things like JS, HTML, Node, Express, databases — all working together in perfect sync. But here’s the crazy part: 👉 One missing semicolon 👉 One wrong bracket 👉 One tiny typo …and the whole thing collapses. It’s honestly insane. Thousands of lines, multiple layers, requests flying, data flowing — and everything depends on absolute precision. No ego, no adjustment, no “it’s okay, close enough.” Either it’s right… or it’s broken. And yet, when it does work — when everything clicks — it feels like magic. Not just software. It’s discipline. It’s logic. It’s trust between systems that don’t forgive mistakes. Makes you respect the invisible structure behind every app we use daily. Perfection isn’t optional here — it’s the baseline. And somehow… we make it work. That’s the beauty of building. #Programming #WebDevelopment #JavaScript #NodeJS #ExpressJS #CodingLife #DeveloperMindset #TechThoughts #BuildInPublic #CodeLife #SoftwareEngineering #Debugging

🚀 Understanding SOLID Principles (in simple terms) As developers, we often focus on writing code that works. But writing code that is clean, scalable, and maintainable is what truly sets you apart. That’s where SOLID principles come in. Let’s break them down 👇 🔹 S — Single Responsibility Principle A class should have only one responsibility. 👉 One class = One job This makes code easier to debug and maintain. 🔹 O — Open/Closed Principle Code should be open for extension but closed for modification. 👉 Add new features without changing existing code 🔹 L — Liskov Substitution Principle Child classes should be replaceable for their parent classes without breaking functionality. 👉 Inheritance should not change expected behavior 🔹 I — Interface Segregation Principle Avoid large, bulky interfaces. 👉 Create small, specific interfaces so classes only implement what they need 🔹 D — Dependency Inversion Principle Depend on abstractions, not concrete implementations. 👉 Makes your code flexible and easy to scale 💡 Why SOLID matters? Cleaner code Better scalability Easier testing Faster development in long run If you’re working with React, Node.js, or any backend system, applying SOLID principles can drastically improve your project structure. 📌 In short: Good code works. Great code is maintainable. #SOLID #CleanCode #PHP #NodeJS #ReactJS #Developers #SoftwareEngineering from Coding-Life

I’ve seen this confusion quite a lot lately, especially among beginners stepping into backend development. Many people think Node.js is a programming language… or sometimes even a framework of JavaScript. Honestly, I used to think the same at one point 😅 But here’s the simple truth: JavaScript is the language. Node.js is just the environment where that language runs outside the browser. That’s it. Before Node.js, we mostly used JavaScript only inside browsers — for things like button clicks, form validation, UI interactions. But Node.js changed the game by letting us use the same JavaScript to build servers, APIs, and full backend systems. So instead of learning a completely new language for backend, you can now do everything with JavaScript. And that’s why Node.js became so popular. One more thing I often notice: People say “Node.js framework” — but it’s not. Tools like Express.js are frameworks that run on top of Node.js. If you’re just starting out, don’t rush into frameworks. Take a little time to understand: – How JavaScript actually works – What Node.js really does behind the scenes – Why async operations and non-blocking behavior matter Trust me, these basics will save you a lot of confusion later. At the end of the day, it’s not about memorizing tools — it’s about understanding what’s happening under the hood. That’s where real growth starts 🚀 #NodeJS #JavaScript #BackendDevelopment #LearningJourney #SoftwareEngineering

Day 2 🚀 It’s working. From idea → to a working CLI that sets up my full stack in one command ⚡ What it does: • Creates frontend/ (Next.js) • Creates backend/ (Express + MongoDB ready) • Sets up basic structure + routes Run once → start coding instantly. Next step: Publishing it as an npm package 📦 Turning a repetitive problem into a real tool feels 🔥 Would you use something like this? #BuildInPublic #JavaScript #NextJS #NodeJS #CLI

I just went down a rabbit hole on React Compiler and honestly… why isn’t everyone talking about this? 🤯 For years, we’ve been writing code like this: const filtered = useMemo(() => items.filter(i => i.type === filter), [items, filter]); const handleClick = useCallback(() => doSomething(), []); const MyComp = React.memo(({ data }) => {data}); And we called it “best practice.” But let’s be honest — it’s mostly boilerplate. It clutters your code, it’s easy to get wrong, and a stale dependency array has burned every React dev at least once. 🚀 React Compiler changes the game. Instead of manually telling React what’s stable, the compiler figures it out at build time by analyzing your data flow. You write this: function ProductList({ items, filter }) { const filtered = items.filter(i => i.type === filter); return ; } And the compiler automatically generates the optimized version: ✔️ Memoization handled ✔️ Dependencies always correct ✔️ No human error ⚠️ The catch? Your code must follow the Rules of React: → No mutating props or state → No conditional hooks → Pure render functions If you break the rules, the compiler simply skips that component — fail-safe by design. 💡 The best part? No new APIs. No new mental model. Just React… but smarter. It’s essentially a Babel plugin you can enable today: // Next.js experimental: { reactCompiler: true } This might be one of the biggest DX improvements React has shipped in years — fewer bugs, cleaner code, and more predictable performance. Still experimental, but very promising. Have you tried it yet? Curious if it actually reduced your need for useMemo/useCallback 👇 #React #ReactJS #Frontend #WebDevelopment #JavaScript #nextjs
