Optimize React State with the Hook Pattern

💡 React 19 Hook Spotlight: useActionState React 19 introduces useActionState, a powerful hook designed to simplify async actions, especially form submissions and API calls. What makes useActionState special? 🔸 Manages state + async logic together 🔸 Built-in loading (isPending) handling 🔸 Cleaner alternative to useState + onSubmit + useEffect 🔸 Works seamlessly with forms and server actions Think of it as: State transitions driven by actions, not events. Instead of juggling multiple states for loading, success, and errors, you return the next state directly from the action. This leads to: 🔷 Less boilerplate 🔷 Better readability 🔷 More predictable async flows If you’re working with modern React or exploring React 19 features, this hook is definitely worth learning early.

Just finished building a Todo App as part of strengthening my React fundamentals. Tech stack used: =>React =>Context API =>Hooks (useState, useEffect) =>Component-based architecture What I focused on: =>Managing global state with Context API =>Clean and reusable components =>Implementing basic CRUD functionality =>Writing readable and maintainable code This project helped me better understand how state flows in real React applications and why structure matters as apps scale. 🔗 GitHub Repository: https://lnkd.in/dzeNy2bd #React #JavaScript #WebDevelopment #FrontendDeveloper #LearningInPublic

🚀 Why Bun Is Faster Than Node.js Bun is gaining attention because it is built with performance and modern developer experience in mind. Main reasons why Bun feels faster: ⚡ Written in Zig - Lower-level control over memory and execution helps reduce runtime overhead compared to Node.js. 🧰 All-in-one runtime - Bun includes a package manager, bundler, test runner, and native TypeScript support. Fewer tools = faster execution. 🚀 Faster startup time - Uses JavaScriptCore, which is highly optimized for quick startup and short-lived processes. 📦 Blazing-fast package installs - Optimized caching and parallel downloads make dependency installation much faster than npm or yarn. 🌐 Web APIs by default - Built-in support for fetch, Request, and WebSocket means fewer dependencies and better performance. 👉 Final thought: Node.js is stable and production-proven, but Bun is a strong choice for modern, performance-focused projects. #Bun #NodeJS #JavaScript #Backend #WebDevelopment 🚀

🚀 Say goodbye to <Context.Provider> redundancy in React! For years, working with the Context API felt a bit clunky. We had to wrap our components in .Provider every single time, easy to forget, messy to read. ⚛️ With React 19, that changes: ❌ Before: <UserContext.Provider> It worked, but it cluttered JSX and felt like an implementation detail. Forget it, and React would either fail silently or break. ✅ Now: <UserContext> The Context object itself is now a valid component. Cleaner, simpler, and more intuitive. Why it matters: 📉 Less Noise: Cleaner JSX, even with multiple nested contexts. 🧠 More Logical: Wrapping a component now reads exactly how we think: “This component uses UserContext.” ⚡ Easy Upgrade: React provides a codemod to update your codebase automatically. 💡 Bonus: <Context.Consumer> is mostly obsolete, useContext or hooks have you covered. Starting React 19, just render <SomeContext> directly, and your JSX becomes clearer than ever. #ReactJS #React19 #WebDevelopment #FrontendDevelopment #JavaScript #SoftwareEngineering

#Day 87, 🚨 Common Mistakes in React JS 🚨 Just wrapped up a session on the most common pitfalls in React JS! 😅 If you're a React dev, listen up! 🙌 🔹 1. Improper Router Rendering - Using <Link> outside <BrowserRouter>? 💥 Wrap it up! - Missing <Route exact path>? 😬 Paths overlapping? Fix it! 🔹 2. Promise Object Mishaps - Handling API calls? 🔄 Use .then() or async/await properly! - Passing params via routes? 👉 Use useParams()! 🔹 3. Component Confusion - Multiple routes with same path? 🚫 Avoid it! - Missing exact keyword? 🔍 Get precise routing! 🔹 4. Ordering of Routes - Order matters! 👉 Put specific routes first. 🔹 5. Sweet Spot for Components - Keep common components in the right place 🌟! 💡 Takeaways: - Use BrowserRouter wisely 🧐 - Handle promises like a pro 🔥 - Route like a boss 🚀 #ReactJS #WebDev #CodingMistakes #Frontend #LearningInPublic 🚀 #ccbp #nxtwave #100daysofcoding

React Strict Mode shows problems you didn’t know you shipped React Strict Mode doesn’t exist to annoy developers. It exists to expose code that only appears correct. When we enabled Strict Mode, things that “worked fine” suddenly started breaking: APIs were called twice effects behaved unpredictably cleanup logic revealed hidden bugs At first glance, it feels like React is doing something wrong. But what it’s really doing is removing your safety net. Strict Mode forces you to write code that: has no side effects during render cleans up effects correctly doesn’t rely on execution order luck What surprised me most was this: the issues it exposed weren’t development-only problems. They were production bugs waiting for the right conditions. If code survives Strict Mode, it’s usually safe for: concurrent rendering Suspense future React changes Disabling Strict Mode doesn’t make your app safer. It just hides the weak spots. #react #frontend #javascript #webengineering #softwarearchitecture #srinudesetti

🚀 Leveling up React-Redux with TypeScript! 🚀 Sharing a quick tip for React + Redux Toolkit developers using TypeScript! Instead of using the plain useDispatch and useSelector hooks directly, it’s a best practice to create typed versions like useAppDispatch and useAppSelector. Why does this matter? ✅ Stronger type safety — Dispatch knows exactly which actions are allowed, and selectors provide accurate state types. ✅ Cleaner, more maintainable code — Reduces repetitive type annotations throughout your components. ✅ Improved developer experience — Better IntelliSense and autocomplete support in IDEs. Here’s a simple example of how to set it up: This pattern ensures that your Redux state and dispatch calls are fully typed across your app, making it easier to scale and maintain. If you’re working with React, Redux Toolkit, and TypeScript, consider adopting typed hooks for safer and cleaner code! 💡 #TypeScript #ReactJS #ReduxToolkit #JavaScript #WebDevelopment #CleanCode #FrontendDevelopment #SoftwareEngineering #CodeQuality #DeveloperExperience #ProgrammingTips #ReactHooks #WebApp #TechTips #CodingBestPractices

Your try-catch block is hiding bugs, not fixing them. 🛑🩹 I’ve been reviewing a lot of Node.js and React code lately where I see this pattern: try { await someCriticalAPI(); } catch (e) { console.log("Error occurred", e); } This is a ticking time bomb. By "swallowing" the error and only logging it to the console, you’ve created a Silent Failure. The UI thinks everything is fine, the user is stuck on a loading spinner, and your backend monitoring never receives an alert. The Senior Approach to Error Handling: Throw or Flow: If you can’t fix the error inside the catch, re-throw it so a global error handler can catch it. User Feedback: Never leave a user guessing. Always trigger an "Error State" in the UI. Observability: Send the error to Sentry, LogRocket, or your internal tracker with the Full Stack Trace. A code that crashes is annoying. A code that fails silently is dangerous. 👇 How do you handle errors in production? Do you use a global error boundary or handle them per request? #SoftwareEngineering #JavaScript #NodeJS #WebDevelopment #APIDesign #CleanCode #adarshjaiswal

🌱 Going back to basics "Controlled Components" While building forms in React, there is one pattern I keep coming back to "controlled components". At first, I honestly did not like it. "value" here, "onChange" there… feels like too much work. But one thing my mentor said stayed with me : “It is about the mental model. It will help you later.” And slowly, it started making sense....!!! Every input "text box", "dropdown" , "checkbox" takes its value from React state. And every change updates that state. One clear source of truth...!! Simple and predictable. Controlled components may look boring, but they make forms easier to manage when things grow bigger. For me, going back to basics means choosing patterns that keep things clear and easy to reason about. And controlled components do exactly that. #ReactJS #ControlledComponents #Frontend #JavaScript #GoingBackToBasics
