Today I explored some important concepts in React that make apps more scalable and dynamic. 🔹 Learned Context API to manage global state 🔹 Worked with React Router DOM for navigation 🔹 Implemented routing using RouterProvider and createBrowserRouter 🔹 Built multiple pages: Home, About, Contact 🔹 Learned how to navigate between pages smoothly 🔹 Extracted dynamic parameters (like id) from URL 🔹 Fetched real data from GitHub API (followers) 🔗 GitHub Profile: https://lnkd.in/gMurynAg 📌 Key takeaway: Understanding routing + global state is a big step toward building real-world React applications. #React #WebDevelopment #JavaScript #Frontend #LearningInPublic #100DaysOfCode

Day 15 #100DaysOfCode 💻 Today I learned how to set up React in VS Code and understood the basic idea of React Components. First, I installed React using Vite and ran the project in VS Code. Then I learned that in React, a function can act as a component and can be used like an HTML tag. Example: function Header() { return <h1>Hello React</h1>; } function App() { return ( <div> <Header /> </div> ); } This means React allows us to build reusable UI pieces using functions. Small step, but an important start in my React journey 🚀 #ReactJS #JavaScript #WebDevelopment #FrontendDevelopment #CodingJourney #Akbiplob

While building React projects, I realized that form handling is one of the most important concepts to master. Almost every application needs forms — login, signup, feedback, search. Here are 4 ways I learned to handle forms in React: 1️⃣ Controlled Components → Using useState to manage input values 2️⃣ Uncontrolled Components → Using useRef to access input directly 3️⃣ Single State Object → Managing multiple inputs with one state 4️⃣ Form Libraries → Using React Hook Form / Formik for scalability The biggest learning for me: 👉 Controlled components give more control 👉 Libraries save time in large applications Still exploring and building more projects 🚀 #ReactJS #WebDevelopment #JavaScript #FrontendDevelopment #CodingJourney

To every developer 𝙘𝙤𝙣𝙛𝙪𝙨𝙚𝙙 between 𝗡𝗲𝘅𝘁.𝗷𝘀 and 𝗥𝗲𝗮𝗰𝘁, I have a simple way to think about it: • 𝗥𝗲𝗮𝗰𝘁 𝗶𝘀 𝗷𝘂𝘀𝘁 𝘁𝗵𝗲 𝗨𝗜 𝗹𝗮𝘆𝗲𝗿: It’s a library for building interfaces. You handle 𝙧𝙤𝙪𝙩𝙞𝙣𝙜, 𝙨𝙩𝙧𝙪𝙘𝙩𝙪𝙧𝙚, and 𝙨𝙚𝙩𝙪𝙥 𝙮𝙤𝙪𝙧𝙨𝙚𝙡𝙛. • 𝗡𝗲𝘅𝘁.𝗷𝘀 𝗶𝘀 𝗮 𝗰𝗼𝗺𝗽𝗹𝗲𝘁𝗲 𝗳𝗿𝗮𝗺𝗲𝘄𝗼𝗿𝗸: It builds on React and gives you everything out of the box. 𝙍𝙤𝙪𝙩𝙞𝙣𝙜, 𝙎𝙎𝙍, 𝙎𝙀𝙊, and 𝙗𝙚𝙩𝙩𝙚𝙧 𝙥𝙚𝙧𝙛𝙤𝙧𝙢𝙖𝙣𝙘𝙚. • 𝗧𝗵𝗶𝗻𝗸 𝗶𝗻 𝘁𝗲𝗿𝗺𝘀 𝗼𝗳 𝘂𝘀𝗲 𝗰𝗮𝘀𝗲: React gives you 𝗳𝗿𝗲𝗲𝗱𝗼𝗺. Next.js gives you 𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 and 𝘀𝗽𝗲𝗲𝗱 in production. That’s the real difference. My simple rule: – 𝗦𝗺𝗮𝗹𝗹 𝗮𝗽𝗽𝘀 → 𝙍𝙚𝙖𝙘𝙩 – 𝗣𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻 𝗮𝗽𝗽𝘀 → 𝙉𝙚𝙭𝙩.𝙟𝙨 Choose based on what you’re building, not just what’s popular.

I’ve used both Redux and Context API in my React projects… and honestly, each has its place. ⚛️ In smaller apps, Context API feels simple and quick. But as things grow, I often switch to Redux for better structure and scalability. That’s something I’ve learned over time: The right choice depends on the project, not the trend. So I’m curious. What’s your go-to for state management? Redux or Context API? #ReactJS #Redux #ContextAPI #FrontendDevelopment #JavaScript

Underrated React libraries more people should be using 👇 1. react-aria → makes accessibility actually manageable 2. valtio → state management without the usual complexity 3. cmdk → build clean command menus (like modern apps) 4. react-resizable-panels → super useful for dashboards 5. usehooks-ts → simple, production-ready hooks Used cmdk recently — really clean and easy to integrate. I’m starting to realize… good frontend isn’t about using popular tools, it’s about using the right ones.

🚀 Understanding React.useEffect Hook — Simplified! If you're working with React, mastering useEffect is not optional — it’s essential. This single hook controls how your app interacts with the outside world 💡 What is useEffect? It’s a built-in hook that runs after your component renders, helping you manage side effects like: 🔹 API calls 🔹 Event listeners 🔹 Timers 🔹 DOM updates ⚙️ How it works 1️⃣ Runs after initial render 2️⃣ Re-runs when dependencies change 3️⃣ Cleans up before next run or unmount 🧠 Real-world use cases ✔ Fetching data from APIs ✔ Handling WebSocket subscriptions ✔ Managing intervals & timeouts ✔ Updating page title dynamically 🔥 Best Practices (Most developers miss this!) ✅ Always use dependency array correctly ✅ Include all dependencies (avoid bugs) ✅ Cleanup side effects to prevent memory leaks ✅ Split logic into multiple useEffects ❌ Don’t overuse useEffect unnecessarily 💬 Pro Insight: A clean useEffect = Better performance + Fewer bugs + Scalable code 📌 Save this post & follow for more practical frontend insights! #ReactJS #useEffect #FrontendDevelopment #JavaScript #WebDevelopment #ReactHooks #CodingTips #SoftwareEngineering #FrontendEngineer #FullStackDeveloper #LearnReact #100DaysOfCode 🚀
