🚀 #Day60 #100DaysOfCode – React Todo App Today I built a Todo App using React to understand how state management and component-based UI work in modern web development. 🛠️ Tech Stack Used Frontend: ▪️ React.js ▪️ JavaScript ▪️ HTML ▪️ CSS Concepts Practiced: ▪️ useState Hook ▪️ useEffect Hook ▪️ Event Handling ▪️ Local Storage 📂 Project Overview This Todo App allows users to: ▪️ Add new tasks ▪️ Mark tasks as completed ▪️ Delete tasks ▪️ Clear all tasks ▪️ Tasks remain saved even after page refresh using Local Storage 💡 Key Learning Today I understood how React state works and how we can build interactive applications using reusable components. Building small projects like this helps strengthen the undamentals of React and frontend development. 🔗 GitHub Repository: https://lnkd.in/dBfWK3QH #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #100DaysOfCode #Day60Complete 🚀

One thing that improved my React code quality a lot When I first started building React apps, my components looked like this: ❌ One large component ❌ API calls inside UI code ❌ Hard to maintain Everything worked… but the code became messy very quickly. Then I started following a clean project structure. Now I separate things like this: 📁 components/ → reusable UI 📁 pages/ → main screens 📁 hooks/ → reusable logic 📁 services/ → API calls 📁 utils/ → helper functions The result? ✅ Cleaner code ✅ Easier debugging ✅ More scalable projects Sometimes improving as a developer isn’t about learning new tools — it’s about organizing what you already know. Curious how others structure their React projects. Do you follow feature-based folders or type-based folders? #ReactJS #FrontendDeveloper #WebDevelopment #JavaScript #CleanCode

🧠 Today I learned something powerful in React: Zustand As I continue building my frontend skills, I explored a lightweight state management library called Zustand — and honestly, it changed the way I think about managing state in React apps. Before this, I mostly used useState and props drilling, which works fine for small apps. But when the app grows, sharing state between components becomes messy and hard to maintain. That’s where Zustand comes in. 🚀 What I learned about Zustand: It allows you to create a global state store outside components Any component can access or update the state directly No need for Context Provider or complex Redux setup Clean, minimal, and very easy to use 💡 Simple idea that helped me understand it: Instead of passing data through components → Zustand keeps the data in one shared store that every component can use directly. This made my code: ✔ Cleaner ✔ More scalable ✔ Easier to manage I really enjoy discovering tools like this because they show me how real-world React applications are structured. Still learning, still building, and getting better every day 💻 #ReactJS #Zustand #FrontendDevelopment #JavaScript #WebDevelopment #LearningInPublic

Built a small Background Changer app while learning React. Simple idea, but a good exercise for understanding components and data flow. Instead of hardcoding colors, I created a reusable Button component and used .map() to render them dynamically with props. Also experimented with Tailwind CSS for smooth hover effects and a small magical text touch. ✨ Step by step, React concepts are starting to click. Click carefully… It’s magic. 😉 #reactjs #webdevelopment #chaiaurcode #tailwindcss

🚀 Day 948 of #1000DaysOfCode ✨ Setting Up Redux in Next.js (The Right Way) State management in modern apps can get messy — especially when you’re working with frameworks like Next.js. In today’s post, I’ve shared a clean and practical setup of Redux in a Next.js application, so you can manage global state without confusion. From configuring the store to integrating it properly with your app structure, this setup ensures everything works smoothly with both client and server rendering. I’ve also focused on keeping the setup scalable, so you’re not just making it work — you’re building it the right way from the start. If you’re building real-world React or Next.js applications, understanding this setup will save you a lot of time and headaches later. 👇 What’s the most confusing part for you when setting up Redux in Next.js? #Day948 #learningoftheday #1000daysofcodingchallenge #FrontendDevelopment #WebDevelopment #JavaScript #React #Next #CodingCommunity #Redux #CodingCommunity

When I first learned about useMemo, I thought: “Great! This will make my React app faster.” So I started adding it everywhere 😅 But later I realized something important: 👉 useMemo is not always necessary. Example: ❌ Overusing useMemo const doubled = useMemo(() => count * 2, [count]); For a simple calculation like this, React is already fast enough. Using useMemo here actually adds unnecessary complexity. ✅ useMemo is useful when: Expensive calculations Large lists filtering/sorting Preventing unnecessary re-renders in heavy components Example: const filteredUsers = useMemo(() => { return users.filter(user => user.active); }, [users]); The real lesson I learned: Optimization should come after clarity. First write clean code. Then optimize when needed. What’s your rule for using useMemo? #ReactJS #ReactHooks #FrontendDevelopment #JavaScript #WebDevelopment

Your React app is slow. Here's why. 🐢 Most devs jump straight to optimization tools. But 90% of the time, the fix is simpler: 🔴 Fetching data in every component independently → Lift it up or use a global state solution 🔴 Importing entire libraries for one function → `import _ from 'lodash'` hurts. Use named imports. 🔴 No lazy loading on heavy routes → React.lazy() exists. Use it. 🔴 Images with no defined size → Layout shifts kill perceived performance 🔴 Everything in one giant component → Split it. React re-renders what changed, not what didn't. Performance isn't magic. It's just not making avoidable mistakes. Save this for your next code review. 🔖 #ReactJS #Frontend #WebPerformance #JavaScript #WebDev

Most React apps don’t become slow because of React. They become slow because of how we use it. Here are some common mistakes I’ve noticed 👇 ❌ Keeping too much state in one component ❌ Unnecessary re-renders due to poor structure ❌ Passing new objects/functions every render ❌ Ignoring memoization completely ❌ Fetching data again and again without caching And the worst one: ❌ Not understanding why something is re-rendering React is fast by default. But without understanding how it works, we end up creating performance issues ourselves. 💡 Small improvements that actually help: • break components into smaller pieces • use React.memo wisely • avoid unnecessary state • use tools like React DevTools Profiler You don’t need advanced tricks. Just understanding the basics deeply is enough. 💬 What’s one React issue that took you a long time to figure out? #ReactJS #FrontendDevelopment #JavaScript #WebPerformance #SoftwareEngineering #DeveloperLife #CodingTips #WebDevelopment

I built a complete enterprise app with NestJS in 48 hours. Here's everything I learned — explained so simply that even a non-developer can understand. NestJS has only 3 concepts: → Module (the container) → Controller (the receptionist) → Service (the worker) That's it. Everything else is this pattern repeated. I made a visual guide breaking down: • Why NestJS exists (and when NOT to use it) • The 3 building blocks with real code • How every request flows — 5 steps • Decorator cheat sheet (save this) • NestJS vs Express — honest comparison Swipe through the carousel ⬇️ --- What backend framework are you using in 2026? ♻️ Repost if this helped someone in your network 💾 Save for later reference #nestjs #backenddevelopment #typescript #webdevelopment #spftwareengineering #development #javascript

Ever wondered which React component is actually slowing down your UI? Most of the time when a React app feels slow, we start guessing: “Maybe it's the API… maybe it's Redux… maybe it's the component tree.” But React already gives us a built-in tool to identify the exact problem: React Profiler. You can open it directly inside React DevTools → Profiler tab and record how your components render. What makes it powerful: • Shows which components re-rendered • Displays how long each component took to render • Highlights unnecessary re-renders • Helps identify components that need memoization For example, I once noticed a list component re-rendering dozens of child items unnecessarily. Using the Profiler made it obvious, and a simple React.memo reduced the rendering work significantly. Instead of guessing performance issues, React Profiler lets you see the exact rendering cost of each component. One of the most underrated tools for debugging React performance. Have you ever used the React Profiler to debug re-renders? #reactjs #frontenddevelopment #javascript #webperformance #webdevelopment
