Debugging Pitfalls: Wrong Password Bug

🚀 Back in the Flow: Mastering Performance in React After a brief break, I’m back to what I love—building and solving logic. Today, I focused on optimizing search functionality using Debouncing in React. When building a search bar, hitting an API on every single keystroke is expensive and inefficient. To solve this, I implemented a custom debouncing logic inside a useEffect hook. 💡 Key Highlights of this Implementation: Controlled Input: Using useState to manage the search query. Debounce Logic: I used setTimeout to delay the API call by 700ms. This ensures the request only fires after the user has stopped typing. Memory Management: A crucial cleanup function (clearTimeout) to prevent memory leaks and race conditions if the user continues typing. Async/Await: Handling API fetching cleanly within the hook. Building these kinds of "logic-heavy" small components is what sharpens the mind for large-scale applications. It's not just about making it work; it's about making it efficient.

Most beginners think Redux DevTools is just a fancy "console.log()". I thought the same. Until I actually started debugging a real feature in my React project. I had a simple flow: • User clicks a button • An action dispatches • The reducer updates the state • The UI re-renders Simple… right? But my UI was not updating correctly. So I started doing what every developer does: "console.log(action)" "console.log(state)" After a few minutes my console looked like a wall of logs. I still couldn't understand: • Which action caused the bug • What the previous state was • What exactly changed Then I opened Redux DevTools. And everything became clear instantly. Redux DevTools shows: • Every action that happened • The payload of that action • The previous state • The next state But the feature that completely changed how I debug Redux was Time Travel Debugging. You can literally move backward through your application's state history. Step by step. Click an action → see the state before it. Click the next action → see what changed. No guessing. No endless logs. Just a clear timeline of your application's state. This is the moment Redux finally clicked for me. Because Redux isn't just about state management. It's about predictable state changes. And Redux DevTools lets you see that predictability in action. If you're learning Redux right now, here's my advice: Don't just install Redux DevTools. Spend time understanding the action timeline. That's where Redux really starts making sense. #react #redux #webdevelopment #frontend #javascript #programming

My laptop started heating up like crazy 🔥 VS Code was lagging every time I opened one of my projects… At first, I thought: “Maybe it’s just my system 🤷♂️” But then I paused and asked: 👉 How big is this project actually? 👉 How much code am I loading every time? So I did what every developer does… I built a tool 😄 🚀 Introducing gs-codecount - A simple npm package that helps you: - Count total lines of code - Analyze project size - Ignore unnecessary folders like node_modules Understand what’s actually slowing things down Turns out… the project was way bigger than I expected 👀 Sometimes the problem isn’t your laptop, it’s the amount of code you’re asking it to handle. 📦 Check it out : https://lnkd.in/gvaJKYeg Launch under Geeta Systems Would love your thoughts and suggestions 🙌 #buildinpublic #javascript #nodejs #developers #opensource #webdev

Excited to announce west-js-app v3.1.0 🎉 I've been building west-js-app — an open-source CLI that scaffolds a production-ready Express + TypeScript backend in seconds. Think of it as `create-react-app`, but for your Node.js backend. With a single command: $ npx west-js-app ...you get a fully configured project with your choice of ORM (Prisma, Drizzle, TypeORM, Mongoose), database, Docker setup, Zod validation, Pino logging, ESLint, Prettier, and Husky pre-commit hooks — all wired up from day one. Version 3.1.0 brings the most requested feature yet: Vitest support ⚡ Here's what's new: • Vitest is now available as an alternative to Jest for unit and integration testing • New --test-framework flag lets you choose between jest, vitest, or none during scaffolding • Tests are only generated when a framework is selected — no clutter if you don’t need it • Improved Jest compatibility on Windows (no extra tooling required) • Boilerplate templates now include explicit Vitest imports for better IDE support Vitest is now the recommended choice for performance-critical projects — it’s faster, native to ESM, and feels right at home alongside modern TypeScript toolchains. If you’re tired of spending the first few hours of every project configuring boilerplate, give west-js-app a try. It’s open source, zero runtime dependency, and you own all the generated code. 🔗 westjs.vishalvoid.com 📦 npm: npx west-js-app ⭐ GitHub: https://lnkd.in/ge5w3peV #OpenSource #NodeJS #ExpressJS #TypeScript #Vitest #BackendDevelopment #DeveloperTools #WebDevelopment

I spent 3 hours fixing a React bug yesterday. The issue wasn’t complex. My approach was. Earlier, whenever something broke in my app, I used to: ❌ randomly change code ❌ refresh again and again ❌ search Stack Overflow immediately Now I follow a simple process: ✅ check component re-renders ✅ inspect props and state flow ✅ verify API response structure ✅ use console logs step-by-step And honestly, debugging became much faster. One thing I’m learning as a developer: Writing code is important. But understanding why code breaks is what actually improves your skills. Curious to know — what’s the toughest bug you fixed recently? #ReactJS #WebDevelopment #JavaScript #FrontendDevelopment #CodingJourney #FullStackDeveloper #MERN

Real talk - 'npm cache clean -- force' has become everyone's first instinct when something breaks. But clearing the cache is not always the answer and running it blindly can waste more time than it saves. Here's when it genuinely fixes the problem, and when it doesn't. 👇 ✅ USE IT WHEN: → You installed a package and it's behaving like an older version → Your node_modules look fine, but the app keeps breaking in weird ways → You're getting checksum or integrity errors during install → You just upgraded Node or npm and things stopped working ❌ DON'T USE IT WHEN: → Your package.json or package-lock.json has conflicts - fix those first → You haven't tried deleting node_modules and reinstalling yet → The error has nothing to do with packages (check your code first 😅) → You're on a slow connection - clearing cache means re-downloading everything The better troubleshooting order: 1. Read the actual error message 2. Delete node_modules and run npm install again 3. Check for version conflicts in package-lock.json 4. Then run npm cache clean -- force if nothing else works The cache is not the enemy. Most of the time, it's doing exactly what it's supposed to do. Save this for the next time your first instinct is to nuke it. 🙃 #DevOps #JavaScript #NodeJS #WebDev #TechTips #SoftwareEngineering #Frontend

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

💡 Lesson Learned Today: While working on implementing search functionality in a React + Redux application, I faced an issue where the search input was updating correctly… but the results were not filtered at all 🤔 After debugging, I discovered an important insight: 👉 Not every “search issue” comes from the frontend. ✔️ The request was being sent correctly ✔️ The search parameter was included in the API call ❌ But the backend endpoint didn’t support filtering with that parameter 🔍 What I learned: Always verify: Is the correct parameter name being sent? Is the backend actually using it? Check the Network tab before assuming the issue 🚀 Sometimes the best debugging skill is knowing where the problem is NOT. #FrontendDevelopment #React #Redux #Debugging #WebDevelopment #LearningJourney
