Optimize Your React Project with a Clear Folder Structure

Went back to core concepts like components, props, state, hooks, and component lifecycle to strengthen my fundamentals. Revisiting the basics always helps uncover better patterns, cleaner code, and improved performance. It’s a good reminder that strong foundations are key to building scalable and maintainable applications. #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #LearningJourney #Revision

Stop Chasing the “Latest Framework” I see a lot of beginners hopping from one framework to another — React today, Vue tomorrow, Svelte next week — thinking that’s the shortcut to being a good developer. Here’s the truth: tools are only as good as your fundamentals. Spend time really mastering: JavaScript fundamentals HTML & CSS deeply Debugging skills Once your foundation is solid, learning any framework becomes easy. Until then, chasing trends is just noise. Focus on building strong skills first. The frameworks will follow. #WebDevelopment #JavaScript #FrontendDevelopment #CodingTips #DeveloperMindset

React gives us powerful optimization tools… But many devs use them randomly. Here’s the simple rule: 🟠 useEffect → for side effects (API calls, subscriptions, DOM work) 🔵 useMemo → to memoize computed values 🟢 useCallback → to memoize functions If you use useEffect for calculations… you’re misusing it. If you pass new functions every render… you cause re-renders. The goal is NOT to use all 3 hooks. The goal is to use the right hook for the right job.

🚀 Day 879 of #900DaysOfCode ✨ Prefer Primitives in `useEffect` Small decisions in React can have a big impact on performance — and dependency management in `useEffect` is one of them. In today’s post, I’ve explained why preferring primitive values in `useEffect` dependencies matters, and how it helps avoid unnecessary re-renders and unexpected effect executions. To make it clearer, I’ve also shared code examples that visually show the difference and the improvement. If you’ve ever faced confusing `useEffect` behavior, this post will help you think more clearly while writing effects. 👇 Have you ever struggled with `useEffect` dependencies?

⚡ Ever wondered how browsers understand JSX when they actually DON'T? When you write JSX, it doesn't reach the browser as-is. Instead, something magical happens behind the scenes ✨ Parcel (your build tool) acts as a manager, delegating the work to Babel - a JavaScript compiler/transpiler that lives in your node_modules. The moment you save? Babel springs into action: JSX → React.createElement() → ReactElement (JS Object) → HTML Element (rendered!) Here's what's really happening: 🔹 JSX - The syntax you love writing (looks like HTML in JavaScript) 🔹 Babel - Transpiles JSX into function calls browsers actually understand 🔹 React.createElement() - Creates React elements describing your UI 🔹 ReactElement - A plain JavaScript object representing the component 🔹 HTML Element - Finally rendered to the DOM Transpilation = Converting code into a format browsers can parse & execute This is why understanding your build tools matters! Babel is literally the bridge between modern developer-friendly syntax and what browsers can actually run. So next time you write JSX, remember - you've got Babel's got your back! 💪 What surprised you most about how your code gets transpiled?

If the page is not reloading… does that mean it’s a Single Page Application? Most developers say yes — and that’s exactly where the confusion begins. What is a Single Page Application (SPA)? A Single Page Application loads one HTML page only once and then updates content dynamically using JavaScript, without full page reloads. 👉 The key idea is how navigation works, not just whether the page refreshes. #SinglePageApplication #SPA #WebDevelopment #FrontendDevelopment  #JavaScript #ReactJS #NextJS #ClientSideRendering #ServerSideRendering  #CSR #SSR #FrontendEngineering #WebDev #Programming #SoftwareDevelopment #TechLearning #LearningInPublic #DeveloperCommunity

React Component Lifecycle – Made Simple Every React component follows a lifecycle — just like a human being: Birth → Update → Death Mounting (Birth) This is when a component is created and added to the DOM. Typical use cases: • Initial API calls • Setting up state • Subscriptions Updating Happens when state or props change and the component re-renders. Used for: • Reacting to data changes • Re-calculations • Side effects Unmounting (Death) When the component is removed from the DOM. Important for: • Cleanup • Removing event listeners • Clearing timers #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #ReactHooks #MERN #Coding #LearningByBuilding #DeveloperLife

🚨 𝐇𝐨𝐰 𝐭𝐨 𝐅𝐢𝐱 𝐓𝐲𝐩𝐞𝐒𝐜𝐫𝐢𝐩𝐭 𝐢𝐬𝐨𝐥𝐚𝐭𝐞𝐝𝐌𝐨𝐝𝐮𝐥𝐞𝐬 𝐄𝐫𝐫𝐨𝐫 𝐢𝐧 𝐍𝐞𝐱𝐭.𝐣𝐬? If your Next.js build fails with this message: Re-exporting a type when isolatedModules is enabled requires using export type Don’t worry, it’s not a complex bug. It’s just about being clear with TypeScript. 𝐖𝐡𝐚𝐭’𝐬 𝐀𝐜𝐭𝐮𝐚𝐥𝐥𝐲 𝐇𝐚𝐩𝐩𝐞𝐧𝐢𝐧𝐠? When `isolatedModules` is enabled, each file is compiled independently. So TypeScript must know exactly: - what is real JavaScript code that needed at runtime. - what is only for type checking. If you export a type like a normal value, the compiler expects it to exist in JavaScript but it doesn’t. That’s why the build fails. ❌ 𝐖𝐫𝐨𝐧𝐠 𝐖𝐚𝐲 export { Profile, saveProfile } from './helpers'; If `Profile` is a type and `saveProfile` is a function, this causes errors in isolated builds. ✅ 𝐂𝐨𝐫𝐫𝐞𝐜𝐭 𝐖𝐚𝐲 // runtime exports export { saveProfile } from './helpers'; // type-only exports export type { Profile } from './helpers'; Easy Rule to Remember: - Use `export {}` for functions, components, constants - Use `export type {}` for types and interfaces Have you encountered this issue? 😀 #creowis #TypeScript #NextJS #FrontendDev #EngineeringTips #WebDevelopment
