Handling Forms in React with Controlled Approach and React Hook Form

⚛️ Common React Mistakes That Are Killing Your Performance 💀 You think your React code is fine… . But these small mistakes are silently breaking your app 👀 Here’s what most developers still do wrong 👇 . ❌ Mutating state directly React won’t re-render properly (page 2)  ❌ Using index as key Leads to weird UI bugs when list updates (page 3)  ❌ Too much global state Unnecessary re-renders & messy logic (page 4)  ❌ useEffect misuse Missing dependency array = infinite loop 🔁 (page 5)  ❌ Storing derived state You’re duplicating logic for no reason (page 6)  ❌ Too many re-renders New objects/functions every render = performance drop (page 7)  ❌ Ignoring loading & error states Your UI breaks when API fails (page 8)  ❌ Poor folder structure Good code needs good organization (page 9)  . 🔥 React isn’t hard… Bad practices make it hard 💬 Clean code = scalable apps 📌 Save this before your next project .

🚀 React Series - Day 3 State - The Reason React Apps Feel Alive Static UI is boring - users expect interaction. That’s where state comes in. State allows components to store data that can change over time, such as: • Button clicks • Form inputs • Toggle switches Whenever state changes, React automatically updates the UI. This is what makes React applications feel dynamic and responsive. 👉 In modern React, state is usually managed using the useState hook. #reactjs #javascript #frontenddeveloper #webdevelopment #codinginterview #learnreact #30daysofcode #programming #reactinterview #react #coding

🚀 React 19 is officially changing the game for form handling! Say goodbye to manual 'loading' and 'error' states forever. The introduction of the `useActionState` hook (formerly useFormState) is a massive win for DX. It automatically handles the transition from pending states to data return without the need for multiple `useState` or `useEffect` calls. Why this is a breakthrough: ✅ Native Pending State: The `isPending` boolean is built-in. ✅ Error Handling: Easily capture and display server responses. ✅ Progressive Enhancement: Forms work even before the full JS bundle loads. ✅ Cleaner UI Logic: Decouple your business logic from your component state. React is moving closer to the platform, and I am here for it! Are you upgrading to React 19 yet?

💡 What is React Hook Form? React Hook Form is a library that helps you handle forms easily and efficiently in React. 👉 Less code 👉 Better performance 👉 Easy validation 👉 Cleaner logic 📌 Why use React Hook Form? • No unnecessary re-renders • Simple form handling • Built-in validation • Scalable for large forms 📌 How it works: 1️⃣ Register inputs 2️⃣ Handle submit 3️⃣ Validate data 4️⃣ Get form values ⚡ It makes form handling fast, clean, and professional.

🚀 React Series – Day 13 useRef - A Simple Way to Persist Values Without Re-rendering In React, most developers rely on state to manage data. But not every value needs to trigger a UI update. This is where useRef comes in. It allows you to store a value that persists across renders without causing the component to re-render. Some common use cases: • Accessing DOM elements (e.g., focusing an input field) • Storing previous values • Managing timers or intervals For example, focusing an input field without re-rendering the component is a perfect use case for useRef. 👉 The key difference: State updates → re-render component useRef updates → no re-render This makes it a great choice for handling values that don’t directly affect the UI. #reactjs #javascript #frontenddeveloper #webdevelopment #codinginterview #learnreact #30daysofcode #programming #reactinterview #react #coding

Stop making this mistake in your useEffect! 🛑 If you are fetching data in React, you need to handle it like a pro. This image shows the difference between a simple fetch and a safe fetch. Here is the main problem: Junior Level: A basic fetch starts every time the ID changes. If the user clicks fast, multiple requests will run at the same time and can cause bugs. Pro Level: A professional uses an AbortController to stop the old request before starting a new one. Why should you use a cleanup function? It prevents "race conditions" where the wrong data might show up on your screen. It makes your app faster and avoids wasting network resources. You can easily cancel the fetch by calling controller.abort() in the return function. This small change makes your React projects much more stable and professional. Do you always use a cleanup function in your useEffect? Let me know! 👇 #ReactJS #WebDevelopment #CodingTips #CleanCode #FrontendDeveloper #JavaScript #Programming

🚀 React Series – Day 6 Handling User Actions in React (Events Made Simple) User interaction is at the heart of every application - clicks, typing, form submissions. In React, handling these actions is straightforward and similar to JavaScript, with a few small differences. Events are written in camelCase, such as: • onClick • onChange • onSubmit Instead of writing inline logic, it’s better to pass a function as a handler. This keeps the code clean and maintainable. 👉 One small but important detail: always pass the function reference, not the function call. This approach helps React efficiently manage user interactions and update the UI accordingly. #reactjs #javascript #frontenddeveloper #webdevelopment #codinginterview #learnreact #30daysofcode #programming #reactinterview #react #coding

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.

- One React Lesson That Made a Difference in How I Code When I first started using React, I used to put everything into one component — state, logic, and UI all mixed together. It worked… but it wasn’t scalable. Then I learned the importance of separation of concerns 👇 Now, I focus on: • Building reusable components • Moving logic into custom hooks • Keeping components clean and easy to read For example, instead of handling API calls inside components, I move them into custom hooks like "useFetch" or into service layers. This small shift made my code: ✔️ Easier to maintain ✔️ More reusable ✔️ Cleaner and more readable Good React code isn’t just about making things work — it’s about making them scalable. 💬 What’s one React concept that improved your code quality? #ReactJS #JavaScript #FrontendDevelopment #ReactNative #CleanCode #WebDevelopment #ReactHooks #CustomHooks #SoftwareEngineering #FrontendEngineer #CodeQuality #ScalableCode #Programming #DeveloperLife #BuildInPublic #LearnInPublic

I just published a new article breaking down some of the most important React fundamentals that finally clicked for me. https://lnkd.in/df7igt6X It covers: - Declarative vs Imperative thinking - Components and Props - State and why it actually matters - The real reason React re-renders - Common mistakes with event handling One of the biggest takeaways for me was understanding this: React doesn’t “update variables” — it re-runs your component, and only state survives between renders. That small shift in thinking makes a huge difference when working with React. If you’re learning React or struggling with concepts like state and re-renders, this might help clarify things. I’d appreciate any feedback or thoughts. #React #JavaScript #Frontend #WebDevelopment #LearningInPublic
