React.js Fundamentals: Components, Props, State & More

Stop writing React like it's 2021. 🛑 The ecosystem has evolved. If you want a cleaner, more performant codebase, it is time to upgrade your patterns: 🔄 Data Fetching: useEffect ❌ TanStack Query ✅ 🧠 Global State: Context API ❌ Zustand ✅ 📝 Forms: useState / useRef spam ❌ React Hook Form / React 19 Actions ✅ ⚡ Performance: useMemo / useCallback ❌ React Compiler ✅ 🎨 Styling: CSS-in-JS / bloated SCSS ❌ Tailwind CSS ✅ 🛡️ Validation: Manual checks & any ❌ Zod + TypeScript ✅ Less boilerplate. Fewer unnecessary re-renders. Better developer experience. What is a tool or pattern you finally stopped using this year? 👇 #ReactJS #WebDevelopment #Frontend #TypeScript #TailwindCSS

Most React Native codebases become a mess by month 3. Not because the developer was bad. Because nobody agreed on a structure from day one. Here's the folder structure I use on every project 👇 src/ ├── components/  → reusable UI only ├── screens/   → one file per screen ├── navigation/  → all route config here ├── hooks/    → useAuth, usePlayer, useBooking ├── store/    → Redux slices ├── services/   → ALL API calls live here ├── utils/    → helpers & constants ├── types/    → TypeScript interfaces └── assets/    → images & fonts 3 rules I never break: 🔴 API calls never go inside components 🟡 Every colour lives in theme.ts — nowhere else 🟢 Types folder grows with the project — never skip it Junior me put everything in /components. 6 months later it had 60 files and zero logic separation. Never again. Save this before your next project 👇 #ReactNative #TypeScript #CleanCode #MobileDev #JavaScript #2026

🚀 Node.js is no longer just a backend runtime — it’s becoming a complete full-stack powerhouse. If you're working with Node.js, here are the latest features and trends you should not ignore 👇 ⚡ 1. Built-in Fetch API (No More Axios Needed) - Native "fetch()" support - Cleaner HTTP calls without external libraries - Lightweight & modern approach 🧵 2. Worker Threads (True Parallelism) - Run CPU-intensive tasks without blocking the main thread - Ideal for heavy computations & real-time apps 📦 3. ES Modules (Stable & Default Direction) - Use "import/export" instead of "require" - Better compatibility with modern JavaScript ecosystem 🚀 4. Node Test Runner (Built-in Testing) - Native testing support ("node:test") - Reduces dependency on external frameworks 🌐 5. Web Streams API - Efficient handling of streaming data - Perfect for large file processing & real-time apps 🔐 6. Improved Security & Permissions (Experimental) - Restrict file system & environment access - Better control over app security ⚙️ 7. Performance Boosts (V8 Engine Updates) - Faster execution - Optimized memory usage 💡 Why this matters? Node.js is evolving into: ✔ Faster backend runtime ✔ More secure environment ✔ Full-stack ready ecosystem If you're a developer working with Angular + Node.js — you're already in a powerful stack 🔥 👉 Which Node.js feature are you currently using in your projects? #NodeJS #BackendDevelopment #JavaScript #FullStack #WebDevelopment #TechTrends #SoftwareEngineering #Coding

React keeps evolving but one thing hasn’t changed: Clean, maintainable components still matter more than trendy patterns. There’s so much noise around tools, libraries and “must-know” tricks that it’s easy to overlook simple patterns that make day to day code better. So switching gears a little from my usual reflective posts today I wanted to share something practical from my experience, 5 React patterns I keep coming back to in real projects that help reduce component bloat, improve readability, and keep code easier to scale. Inside the carousel: 1. Early returns over nested conditions 2. Custom hooks for cleaner logic 3. Object maps over condition chains 4. When not to overuse useMemo 5. Splitting UI from business logic None of these are flashy. They’re just small patterns that compound. Save it for your next React refactor if useful. ⚛️♻️ #ReactJS #FrontendDevelopment #JavaScript #SoftwareEngineering #WebDevelopment #CleanCode #FullStackDeveloper

🚀 Day 23/30 – React Best Practices Most React developers don’t struggle with syntax… 👉 They struggle with writing maintainable code 👀 Today I focused on what actually makes code production-ready ⚡ 💡 What I realized: Clean code is not about making things “look good” 👉 It’s about making code easy to understand, scale, and debug 💻 Practices I’m following: ✅ Keep components small & focused → One component = one responsibility ✅ Use meaningful names → Code should explain itself (no comments needed) ✅ Avoid prop drilling → Use Context when data goes deep ✅ Reuse logic with custom hooks → Don’t repeat yourself ✅ Separate business logic from UI → Components should focus on rendering ✅ Handle loading & errors properly → Real apps are not always “happy path” 🔥 Reality Check: 👉 Messy code works… until it doesn’t 👉 Clean code scales… messy code breaks ⚡ Advanced Insight: Senior developers don’t write “clever” code 👉 They write predictable, readable code 🔥 Key Takeaway: Anyone can write code that runs 👉 Not everyone writes code that lasts Be honest 👇 Would another developer understand your code in 30 seconds? 👀 #React #CleanCode #FrontendDevelopment #JavaScript #BestPractices

I stopped writing messy React code… and my projects became 10x easier to maintain. Here’s what changed 👇 Most developers focus on “making it work.” But clean code is what makes it scalable. One simple habit I adopted: 👉 Extract logic into reusable hooks Instead of this 👇 useEffect(() => { fetch("/api/users") .then(res => res.json()) .then(data => setUsers(data)) .catch(err => console.error(err)); }, []); I now do this 👇 // useFetch.js import { useState, useEffect } from "react"; export function useFetch(url) { const [data, setData] = useState(null); useEffect(() => { fetch(url) .then(res => res.json()) .then(setData) .catch(console.error); }, [url]); return data; } Then use it anywhere 👇 const users = useFetch("/api/users"); 💡 Why this matters: Cleaner components Reusable logic Easier debugging Better scalability Small improvements like this separate average developers from great ones.

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

Starting My React.js Journey – Basics with Code! Today, I revisited the fundamentals of React.js, and I believe mastering the basics is the key to building powerful applications. Sharing a quick snippet that demonstrates how simple and clean React can be import React from "react"; function Welcome() { const name = "Developer"; return ( <div> <h1>Hello, {name} </h1> <p>Welcome to React Basics!</p> </div> ); } export default Welcome; What this covers: - Functional Components - JSX (JavaScript + HTML) - Dynamic Data Rendering using variables Key Learning: React is not just a library — it's a mindset of building reusable and maintainable UI components. Next Steps: - Props & State - Event Handling - Component Lifecycle Consistency beats intensity. Small steps every day = Big growth #ReactJS #WebDevelopment #JavaScript #Frontend #CodingJourney #100DaysOfCode

#Hello #Connections 👋 #100DaysOfCodeChallenge | #Day72 Project: Full Stack Task Manager (CRUD with Backend Integration) What I built Today I built a complete Task Manager application with full CRUD operations connected to a backend API. This project simulates a real-world workflow where tasks are stored, updated, and deleted from a server instead of just the frontend. Technologies Used HTML5 CSS3 (Responsive UI) JavaScript (Fetch API, DOM Manipulation) Node.js Express.js Features ✔ Add new tasks with title & description ✔ Edit existing tasks ✔ Delete tasks ✔ Fetch tasks from backend API ✔ Real-time UI updates after every action ✔ Clean and responsive design ✔ Proper API integration (GET, POST, PUT, DELETE) Challenge I faced Handling asynchronous API calls while keeping UI updated correctly after every operation. How I solved it Used async/await with proper error handling and reloaded task list after every operation to keep UI in sync with backend. Feedback is always welcome!
