Building Mini-Vite: Uncovering Vite's Speed Secrets

💻 5 React mistakes I stopped making (and it improved my code a lot) When I started with React, I used to write code that worked… But not code that was clean, scalable, and maintainable. Here are 5 mistakes I fixed: ❌ 1. Writing everything in one component 👉 Now I break UI into small reusable components ❌ 2. Ignoring proper state management 👉 Learned when to use useState vs useEffect vs lifting state ❌ 3. Not handling performance 👉 Started using memoization (useMemo, useCallback) ❌ 4. Poor folder structure 👉 Now I follow a clean project structure ❌ 5. Debugging randomly 👉 Now I debug step-by-step with proper logs Small changes… but huge difference in code quality 🚀 Still learning every day 👨💻 Which mistake did you make the most? 😅 #ReactJS #FrontendDevelopment #JavaScript #CleanCode #WebDevelopment #SoftwareEngineer

The Node.js vs. Bun.js debate is officially over for me 🚀 I finally reached my breaking point with the "old way" of doing things. We’ve all been there: spending way too much time configuring tools instead of actually writing code. If you’re still wrestling with npm install taking a literal coffee break or managing three different packages just to run a TypeScript file, you're living in the past. Bun isn't just a faster runtime; it’s a total shift in the developer experience. Here is why I’m never looking back: Speed is an understatement: We’re talking about a runtime built from the ground up for performance. It’s snappy, it’s lean, and it makes Node feel like it’s running through mud 🏃♂️💨 The "All-in-One" Holy Grail: No more installing tsc or nodemon or dotenv. Bun just handles TypeScript, JSX, and environment variables natively. It’s the clean slate we’ve needed for years 🛠️ Install times that don't hurt: Using bun add feels like a cheat code. My terminal actually keeps up with my brain for once. Node had a legendary run and it built the web we use today, but the future is about removing friction. Modern development needs tools that stay out of the way and let us build fast. Bun is that future ⚡️ If you haven't made the switch yet, what's actually holding you back? 🧐 #SoftwareEngineering #WebDev #BunJS #FullStack #TypeScript #CodingLife #TechTrends

🚀 Today I Learned: React Lifecycle (Class vs Functional Components) Today I spent some time understanding how React components live, update, and disappear inside an application. This concept is called the React Lifecycle. Every component in React goes through three main phases: 🔹 Mounting – When a component is created and added to the DOM for the first time. In class components this involves steps like the constructor, rendering the UI, and then running logic after the component is mounted. 🔹 Updating – This phase happens whenever state or props change. React re-renders the component and updates the DOM with the new changes. 🔹 Unmounting – This is when a component is removed from the DOM. Any cleanup logic should happen here. One interesting thing I realized is how functional components handle lifecycle differently compared to class components. Instead of multiple lifecycle methods, functional components mainly rely on effects and dependencies to control behavior during mounting, updating, and unmounting. 💡 My key takeaway today: Even though the implementation looks different in class and functional components, the core lifecycle phases remain the same — Mount → Update → Unmount. Understanding this makes it much easier to reason about when and why React components run certain logic. Learning React step by step and connecting these concepts is starting to make the framework feel much more intuitive. #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #LearningInPublic #100DaysOfCode #DeveloperLife #Coding #BuildInPublic #CodingChallenge #FrontendDeveloper #DeveloperJourney #WebDevCommunity #MERNStack #Consistency #TechLearning #FullStack

#One_real_production_lesson_frontend_dev_taught_me: We had a bug in production where an API was getting called twice. At first, it looked like a backend issue. But the backend logs were clean. So I started digging into the frontend 👇 The culprit? 👉 React 18 Strict Mode. In development, React intentionally runs components twice to detect side effects. But our code wasn’t written with that in mind. Here’s what we had: ❌ API call inside "useEffect" without proper safeguards ❌ No cleanup / idempotent logic ❌ Assumption: "useEffect runs only once" Result: Duplicate API calls → inconsistent data → confused users. --- ✅ Fix: - Made API calls idempotent - Added proper checks before firing requests - Avoided unnecessary side effects inside "useEffect" --- 💡 Lesson: Writing code that works is easy. Writing code that works in real-world scenarios is the real skill. React doesn’t cause bugs. Our assumptions do. --- Since then, I always ask: 👉 “What happens if this runs twice?” 👉 “Is this safe in concurrent rendering?” --- Still learning something new every day 🚀 #FrontendDevelopment #ReactJS #JavaScript #CleanCode #WebDevelopment #Debugging

🚀 6 React Hooks that changed how I write code — and will change yours too. If you're still confused about when to use what, here's the simplest breakdown: 🔵 useState → Store & update values. Every re-render starts here. 🌐 useEffect → Talk to the outside world (APIs, DOM, subscriptions). 📦 useRef → Hold a value WITHOUT triggering a re-render. A hidden drawer for your data. 🧠 useCallback → Memoize functions so they don't get recreated on every render. ⚡ useMemo → Cache expensive calculations. Only recompute when dependencies change. 🌍 useContext → Share state globally. No more prop drilling through 5 layers. The moment these clicked for me, my components became cleaner, faster, and way easier to debug. Which hook took you the longest to truly understand?

When React first introduced Hooks, it completely transformed how developers write and manage components. Instead of relying heavily on class components, we can now handle state, side effects, and complex logic using simple functions. Here are a few Hooks that every React developer should master: >> useState – Manage local state in functional components. >> useEffect – Handle side effects like API calls, subscriptions, and DOM updates. >> useContext – Access global data without prop drilling. >> useRef – Persist values and directly interact with the DOM. >> useMemo & useCallback – Optimize performance by memoizing values and functions. Why Hooks matter: Cleaner and more readable code Better logic reuse through custom hooks Easier state management in functional components Improved component composition In modern React development, Hooks are not just a feature — they are the foundation of scalable and maintainable applications. If you're learning React today, mastering Hooks is a must.

I'm currently focusing on my backend journey 🚀 No fancy designs for now just logic, APIs, and making things actually work. Today I built a Color Scheme Generator from scratch using vanilla JavaScript. It connects to a real API, fetches live data, and displays a full color palette on the page. Small project. Big lesson. I learned: → How to call an external API with fetch() → How async/await works and why it matters → How to dynamically create and update the DOM → How to read API documentation and use it Every project teaches me something new — and I'm just getting started. 🔗 GitHub: https://lnkd.in/dVxnrRWU #JavaScript #Backend #100DaysOfCode #WebDevelopment #Learning

Most beginners think React is complicated… But honestly, it becomes simple when you understand a few core hooks. Today I revised the fundamentals, and here’s a clean breakdown - 1. useState - Used to manage state inside a component. Whenever state changes, React re-renders the UI. 2. useEffect - Handles side effects like API calls, DOM updates, or event listeners. Runs after render and can be controlled using dependencies. 3. useContext - Helps share data globally without passing props manually at every level. Very useful to avoid prop drilling. 4. useReducer - Best for managing complex state logic. Works like a simpler version of Redux with actions and reducers. 5. useRef - Stores values that don’t trigger re-render. Also used to directly access DOM elements. 6. useMemo & useCallback - Used for performance optimization. They help avoid unnecessary re-renders and expensive calculations. The goal is not to memorize everything… The goal is to understand when and why to use each hook. Still learning. Still improving. 🚀 #React #WebDevelopment #JavaScript #Frontend #LearningInPublic

One thing I often notice while learning and working with React is that many beginners only focus on the most common hooks like useState and useEffect. They see other hooks but usually just go through them quickly without understanding their real purpose. However, React provides many hooks and each of them solves a specific problem. Ignoring them means missing powerful tools that can make your code cleaner and more efficient. For example, instead of managing too many states inside a component with multiple useState calls, you can use useReducer to manage complex state logic in a more organized way. Similarly, useRef is very useful when you want to persist a value without causing a re-render or when you need to access a DOM element directly. For instance, you can use useRef to focus an input field automatically when a component loads. Hooks like useMemo and useCallback help optimize performance by preventing unnecessary calculations and function recreations in larger applications. And in routing scenarios, useNavigate makes navigation between pages simple and programmatic. The key point is: if you want to become strong in React, it's important not to just memorize hooks but to understand when and why they should be used. Once you start understanding the real use cases of these hooks, your code becomes more structured, efficient, and scalable. #React #WebDevelopment #FrontendDevelopment #JavaScript #ReactJS
