React Router Mastery: Building Scalable Frontend Apps

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

After spending an afternoon with Next.js 14, I noticed how much smoother frontend work can be. The new advanced server components really cut down the usual data fetching headaches in React. Routing updates make nested layouts easier to manage—a relief since it felt clunky before. Image optimization loads pages faster without extra effort. I tried it out with Vercel and Playwright for testing, and both tools felt more seamless than usual. If you work with React and Next.js and want to speed up your development, this update is worth checking out. Has anyone swapped Cypress or Copilot into their Next.js 14 projects yet? #Nextjs #ReactJS #FrontendDevelopment #WebDevelopment #ServerComponent

🚀 NexGo vs React.js vs Next.js — The Future of Frontend? I’ve been exploring a new framework called NexGo, and it got me thinking… How does it compare with React.js and Next.js? 🔗 Check it out here: https://lnkd.in/gE2BHFvd ⚡ NexGo (New Player 👀) Lightweight & fast (Go-powered ecosystem?) Focus on performance + simplicity Aims to replace heavy JS frameworks Still early, but interesting direction 👉 Could be a game-changer if it scales

🚀 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 🚀

Mastering React Hooks made my frontend journey 10x easier 🚀 Here’s a simple breakdown 👇 🔹 State Management Hooks: • useState → manage simple state • useReducer → handle complex logic • useContext → share data globally 🔹 Side Effect Hooks: • useEffect → API calls, lifecycle tasks • useCallback → optimize functions • useMemo → improve performance 👉 If you understand these hooks, you can build powerful React apps easily. Which React Hook do you use the most? 🤔 #reactjs #frontend #webdevelopment #javascript #coding

Everyone says use React.lazy. Here's when it actually makes things worse. React.lazy splits your bundle. That sounds good on paper. But there's a hidden cost: → Waterfalls → Layout shift → Spinner hell on fast connections I've seen apps where lazy-loading a modal added 400ms of perceived lag — on a 100ms network. Why? Because the component fetch only starts when the user triggers it. By then it's already too late. 𝗧𝗵𝗲 𝗳𝗶𝘅 𝗶𝘀𝗻'𝘁 𝘁𝗼 𝘀𝘁𝗼𝗽 𝘂𝘀𝗶𝗻𝗴 𝗥𝗲𝗮𝗰𝘁.𝗹𝗮𝘇𝘆. 𝗜𝘁'𝘀 𝘁𝗼 𝗸𝗻𝗼𝘄 𝘄𝗵𝗲𝗻 𝘁𝗼 𝗽𝗿𝗲𝗳𝗲𝘁𝗰𝗵. Call your import() on onMouseEnter — not on render. The chunk loads in the ~200ms before the click lands. By the time the modal opens, it's already there. If a user is likely to click something within 3 seconds of landing on a page — don't lazy load it. Preload it instead. React.lazy is a network tool. Treat it like one. What did you lazy-load that you later regretted? #ReactJS #Frontend #WebPerformance #JavaScript #WebDev

Built multiple projects with React, and one thing I’ve realized is performance isn’t just about code — it’s about the right tools. React gives flexibility with components, hooks, and rendering control. But when it comes to production-level optimization, Next.js adds that extra edge with SSR, SSG, routing, and built-in optimizations. Understanding where to use what makes the real difference 🚀 #React #NextJS #WebDevelopment #Frontend #Performance #JavaScript
