Most React developers write custom hooks. But many of them don’t scale. You only realize this when your app grows. At first, hooks feel easy: Fetch data → store state → return it. Everything works… until: → You need the same logic in multiple places → Small changes break multiple screens → Side effects become hard to track → Debugging takes longer than expected The problem? We treat hooks like shortcuts instead of thinking about structure. What works better: → Keep hooks small and focused → Don’t hardcode logic — pass it as input → Separate fetching, logic, and UI → Return consistent values (data, loading, error) → Avoid unexpected side effects Simple mindset shift: Custom hooks are not just helpers. They define how your app handles data and logic. If a hook is poorly designed: → it slows you down later If it’s well designed: → everything becomes easier to scale Some of the React issues I’ve seen, started with bad hooks, not React itself.

📁 A React Folder Structure That Scales When I first started building React applications, my folder structure usually looked like this: components/ pages/ utils/ It worked fine for small projects. But as the application grew, things started getting messy: • Components were hard to find • Logic was scattered across folders • Maintaining the project became difficult So I started exploring feature-based folder structures, and it made a big difference. Here’s a simple scalable structure I’ve been using lately 👇 src/ ├── components/ ├── features/ │  ├── auth/ │  │  ├── components/ │  │  ├── hooks/ │  │  ├── services/ │  │  └── authSlice.js │  ├── dashboard/ │  └── profile/ ├── hooks/ ├── services/ ├── utils/ └── pages/ Why this works better 👇 🔹 Feature-based organization All related logic stays together. 🔹 Better scalability Adding new features becomes easier without cluttering the root structure. 🔹 Improved maintainability Developers can quickly understand where everything lives. Over time I realized that good project structure is just as important as writing good code. It saves time, reduces confusion, and helps teams collaborate better.

The React Hook "Periodic Table": From Basics to Performance ⚛️ If you want to write clean, professional React code in 2025, you need more than just useState. While useState is the heart of your component, these 7 hooks form the complete toolkit for building scalable, high-performance apps. Here is the breakdown: 🌟 The Core Essentials 1️⃣ useState: The bread and butter. Manages local state (toggles, form inputs, counters). 2️⃣ useEffect: The "Swiss Army Knife." Handles side effects like API calls, subscriptions, and DOM updates. 3️⃣ useContext: The prop-drilling killer. Shares global data (themes, user auth) across your entire app without passing props manually. ⚡ The Performance Boosters 4️⃣ useMemo: Caches expensive calculations. Don't re-run that heavy data filtering unless your dependencies actually change! 5️⃣ useCallback: Memoizes functions. Perfect for preventing unnecessary re-renders in child components that rely on callback props. 🛠️ The Power Tools 6️⃣ useRef: The "Persistent Finger." Accesses DOM elements directly (like auto-focusing an input) or stores values that persist without triggering a re-render. 7️⃣ useReducer: The "Traffic Cop." Best for complex state logic where multiple sub-values change together. If your useState logic is getting messy, this is your solution. 💡 Pro-Tip : Keep an eye on React 19 hooks like useOptimistic (for instant UI updates) and useFormStatus (to simplify form loading states). The ecosystem is moving fast! Which hook do you find yourself reaching for the most lately? Is there a custom hook you’ve built that you now use in every project? 👇 #ReactJS #WebDevelopment #Frontend #CodingTips #Javascript #SoftwareEngineering #ReactHooks #WebDev2025

Running 6 projects locally shouldn't require 6 terminals, Docker Desktop, and 4 GB of RAM. I built AppNest — a 2 MB native app that replaces all of that. Add your projects. Pick a type. Hit Start. Done. The problem: Every day I juggle multiple web projects — .NET APIs, React frontends, Node microservices. Each needs its own terminal, its own build commands, its own port. Close the wrong tab and you lose your logs. Docker Compose works but eats RAM, slows down hot reload through volume mounts, and turns private NuGet/npm feeds into a credentials nightmare. The solution: AppNest is a single executable with an embedded web dashboard. No installer, no runtime, no config files. It manages your apps as native processes — same as running them from a terminal, but with a UI on top. What you get: ✅ One-click build & run for .NET, Node.js, React, Angular, Vue, Next.js, Express ✅ Dev & Release mode presets — dotnet run for dev, full publish pipeline for release ✅ Live color-coded logs with error highlighting and clickable URLs ✅ Built-in static file server with SPA fallback (no need for npx serve) ✅ System tray — runs in background, start/stop all from the tray menu ✅ Auto-start apps on launch, drag-and-drop reordering ✅ Persistent file-based logs with export ✅ Private feeds just work — inherits your .npmrc, nuget.config, VPN, proxy settings What it costs: 🔹 2 MB on disk 🔹 ~10 MB RAM at runtime 🔹 Zero dependencies — no Node.js, no Docker, no Electron Built with Rust, Axum, and Tokio. The HTML/CSS/JS dashboard is compiled into the binary at build time via rust-embed. The server binds to localhost only — nothing is exposed to the network. It's not a Docker replacement. Docker is the right tool for production, CI, and reproducible environments. AppNest is for the developer inner loop — when you just want your apps running and visible while you code.

🍳 Introducing RecipeLens — a recipe discovery app I built from scratch using React.js! The idea is simple: type in ingredients you already have at home, and get real recipes instantly. What I built: → Ingredient-based recipe search using the Spoonacular API → Recipe detail pages with full instructions → Save & manage your favorite recipes (persisted with localStorage) → Smooth animations, hover effects, and fully responsive UI → Loading & error states for a real production-like experience What I learned building this: → API integration with fetch & async data handling → React hooks — useState, useEffect, useRef, and more → React Router for multi-page navigation → Component architecture and lifting state up → sessionStorage vs localStorage for smart data persistence This project pushed me out of my comfort zone more than once — and that's exactly where the real learning happened. 🔗 Live Demo: https://lnkd.in/dbnFcc6W 💻 GitHub: github.com/Jawairia-Mazhar #React #Frontend #WebDevelopment #JavaScript #OpenToWork

🚀 Stop Learning Next.js the Wrong Way Most developers jump into Next.js thinking it’s just “React + routing”. It’s not. If you treat Next.js like plain React, you’ll: ❌ Overuse client components ❌ Break performance ❌ Miss the power of server-side architecture Here’s what actually matters 👇 💡 1. Server Components > Client Components Use server by default. Only go client when you need interactivity. 💡 2. Keep Pages Thin Your UI should NOT contain business logic. Move data fetching & logic into services. 💡 3. App Router is a Game Changer Layouts, nested routing, and streaming make your app scalable from day one. 💡 4. Data Fetching is Built-In Forget heavy state libraries for everything. Use async/await directly inside components. 💡 5. Think in Architecture, Not Pages Good Next.js apps are structured like systems — not random components. 🔥 If you're learning Next.js, focus on: • Structure • Separation of concerns • Server-first mindset Not just UI. 💬 What’s the biggest mistake you made while learning Next.js? #NextJS #ReactJS #WebDevelopment #FullStack #JavaScript #Frontend #Backend #SoftwareEngineering

🎬 As a movie addict like myself, I wanted to challenge myself and test my skills in React by building something I genuinely enjoy — a movie-list web application. I recently developed a full-stack movie app that lets users browse, search, and save their favorite movies — turning a simple idea into a complete end-to-end project. 🔧 Tech Stack: • Frontend: React (with Vite) • Backend: Node.js + Express • Database: MongoDB (Mongoose) • API: TMDB (The Movie Database) ✨ Features: • Browse trending & popular movies • Search movies instantly • Add/remove favorites ❤️ • Persistent storage with MongoDB • Dynamic UI updates across pages 💡 What I learned: • Building REST APIs from scratch • Connecting React frontend to a backend server • Handling CORS and environment variables securely • Debugging real-world full-stack issues • Managing global state in React This project really helped me understand how modern web applications work behind the scenes and strengthened my full-stack development skills. Next steps: ➡️ Add user authentication ➡️ Deploy the app (Vercel + Render) ➡️ Improve UI/UX with animations and smoother interactions Always open to feedback and opportunities to improve! git: https://lnkd.in/e8YXtdWc #React #NodeJS #MongoDB #FullStack #WebDevelopment #Projects #SoftwareEngineering

🚀 React Folder Structure: Standard vs Feature-Based As a Software Developer, when working with React, one question I often see is: 👉 “Which folder structure is best?” Let’s break it down simply 👇 ⚡ 1. Standard Folder Structure - Organizes code by type (components, hooks, pages) - Easy to start with - Works well for small projects ❌ Problem: As your app grows, files get scattered → Login logic, UI, API calls = different folders → Hard to track & maintain 🔥 2. Feature-Based Folder Structure - Organizes code by feature/module (Auth, Dashboard, etc.) - Each feature contains: → Components → Hooks → API/Query → Business logic ✅ Everything related to a feature stays in one place ⚔️ Key Differences Standard → Type-based separation Feature-based → Feature-based grouping Standard → Simple but messy at scale Feature-based → Structured & scalable Standard → Hard to refactor Feature-based → Easy to extend 💡 Benefits of Feature-Based Architecture ✔ Scalable for large applications ✔ Better code ownership (team-wise) ✔ Easier debugging & maintenance ✔ Faster onboarding for new developers ✔ Clean separation of concerns 🧠 When to Use What? 👉 Use Standard Structure → Small projects, → MVPs, → Quick prototypes 👉 Use Feature-Based Structure → Mid to large-scale apps, → Production-level systems, → Teams working on multiple modules 💬 What structure are you using in your current project?
