Building a CRUD System with React Hook Form

Form Handling in React JS Forms are an important part of almost every web application. Learning how to handle them properly in React helps in building better and more user-friendly applications. Here are a few key concepts: Controlled components: Managing form inputs using state Validation: Ensuring correct data before submission Error handling: Showing clear messages to users Reusable components: Writing clean and maintainable code Libraries like React Hook Form and Yup make form handling easier and more efficient. #ReactJs #Development #javascript

Half the JavaScript your app ships is never used. Not on slow connections. Not on fast ones. Never. According to HTTP Archive's, the median page ships 613KB of JavaScript on desktop. Roughly half of it is never used during page load. What it does Code splitting divides your bundle into smaller chunks that load only when required. For example, one production React application reduced its bundle size from 2.3MB to 875KB and improved Time to Interactive from 5.2 seconds to 2.7 seconds. Where to split Routes — always first Heavy libraries — 200–500KB each Modals, drawers, PDF export — rarely used, no reason to preload Permission-based chunks — admin panels, billing, or internal tools, in bundles for users who cannot access them. This practice avoids unnecessary data transfer and potential security concerns. The trap I see most often Avoid splitting too aggressively at the component level, as it can lead to excessive network requests. Instead, split at logical boundaries that align with the user journey rather than the file structure. Code splitting is a simple yet significant technique. #Frontend #JavaScript #WebPerformance #React #CodeSplitting #WebDev #SoftwareEngineering #Programming

A simple roadmap that actually works: 1. Start with the fundamentals of the web — how the internet works, browser rendering, and HTTP basics. 2. Learn HTML to structure content, then CSS to style and design. 3. Build your logic skills with JavaScript — that’s where websites come to life. 4. Pick up tools for faster, cleaner development: · Git & GitHub (version control) · SASS (better CSS) · Bootstrap or Tailwind (modern UI) 5. Step into real-world development: · Node.js for backend basics · React.js for powerful UIs 6. Level up with: · TypeScript (safer code) · Next.js (production-ready apps) The key isn’t learning everything at once — it’s learning step by step and building projects along the way. Consistency beats everything. #FrontendDeveloper #WebDevelopment #JavaScript #ReactJS #CodingJourney #Developers #LearnToCode

One React Hook changed the way I build dynamic forms. And honestly, it saved me from a lot of messy code. Before using useFieldArray in React Hook Form, I used manual state for dynamic fields. At first, it looked manageable. But as the form started growing, the logic became messy very quickly. Adding fields, removing fields, keeping values in sync, and handling validation started taking more effort than expected. The feature was simple, but the code was not. Then I started using useFieldArray. That is when I understood how useful this hook is in real projects. It makes dynamic form handling much cleaner. Add and remove actions become easier. The structure feels more organized. And the code becomes easier to maintain. For me, the biggest lesson was simple: Sometimes a problem feels difficult not because it is truly hard, but because we are solving it in a harder way. If you work with dynamic forms in React, this hook is worth understanding deeply.

Built a simple Counter App using HTML, CSS, and JavaScript. Increase ➕ Decrease ➖ Reset 🔄 — works similar to cart quantity updates. This project helped me understand DOM manipulation and dynamic value updates. GitHub Repository : https://lnkd.in/gZzUcGWT Live Demo : https://lnkd.in/gYbGruAM #JavaScript #Frontend #Learning

I used to think performance optimization is for advanced developers… So I ignored it. Focused only on building features. But during one project, I noticed: Slow loading Unnecessary re-renders Heavy components That’s when it clicked. 👉 Performance is not optional anymore Now I focus on: • Smaller components • Optimized rendering • Clean logic The biggest learning: A fast app is always better than a complex one. What do you prioritize more: Features or performance? #ReactJS #WebPerformance #FrontendDeveloper #JavaScript

Built a real DOM-based project today......a To-Do List And honestly, it taught me more than I expected. Here’s what it does: - You can type a task and add it using a button - Or simply press Enter on the keyboard to add it instantly - Each task gets added dynamically to the list - Task counters update in real time (In Progress + Completed) - You can delete tasks anytime - You can also mark tasks as completed and track progress What seemed like a “simple project” actually pushed me to understand how everything connects behind the scenes: - How DOM updates work in real time - How events like clicks and keyboard inputs interact with JavaScript - How dynamic UI changes without refreshing the page Even a basic To-Do app contains the core logic of real-world applications. Small steps. Real understanding. Constant building. 💻🔥 #WebDevelopment #JavaScript #DOM #FrontendDevelopment #BuildInPublic

🚀 Understanding CORS (Cross-Origin Resource Sharing) Simplified for Developers If you’ve ever seen this error in your browser 👇 “No 'Access-Control-Allow-Origin' header is present…” Congrats — you’ve met CORS 😅 Let’s break it down in the simplest way 👇 🔹 What is CORS? CORS is a browser security feature that controls how your frontend and backend communicate when they are on different origins. 👉 Example: Frontend: http://localhost:3000 Backend: http://localhost:5000 Different ports = different origin → 🚫 blocked by default 🔹 Why does it exist? To protect users from malicious websites making unauthorized requests using their browser. 🔹 How does it work? When your frontend makes a request: Browser sends the request with origin info Server responds with permission headers Browser decides: allow ✅ or block ❌ 🔹 Common Fix (Node.js / Express) import cors from "cors"; app.use(cors({ origin: "http://localhost:3000" })); 🔹 Key Points to Remember ✔️ CORS is enforced by the browser ✔️ Backend must allow the origin ✔️ Postman/cURL don’t care about CORS ✔️ Never blindly use * in production 🔹 Pro Tip 💡 If you're working with React / Next.js + API, always configure CORS early — it saves hours of debugging. 💬 Have you faced CORS issues before?

The Core Difference React.js: A flexible JavaScript library for building modular user interfaces. Next.js: A powerful React framework engineered for production-scale applications. Key Differences: • Rendering → React: CSR | Next.js: SSR, SSG & ISR • Routing → React: Requires extra libraries | Next.js: File-based routing • SEO → React: Limited | Next.js: Excellent • Performance → React: Manual optimization | Next.js: Built-in optimization • Features → React: Basic setup | Next.js: API routes, Image optimization & more When to choose what? ✅ Choose React for maximum flexibility and custom setups 🚀 Choose Next.js for speed, SEO, and production-ready apps 💬 Most modern projects today are moving toward Next.js.

👀At first, it looked like just another basic project — but it actually helped me understand how real web apps work behind the scenes. 🔹 What I implemented: * Create tasks (POST) * View tasks (GET) * Update tasks (PUT) * Delete tasks (DELETE) 🔹 Tech used: * HTML, CSS, JavaScript * Express.js * Fetch API 💡 What I really learned: * How API calls work between frontend and backend * How data flows through requests and responses * Handling async operations using Promises * Building and structuring a basic REST API This project helped me move from just writing code → to actually understanding it. #WebDevelopment #FullStack #JavaScript #ExpressJS #LearningInPublic
