Moving API calls out of React components for cleaner code

You know how to create components in React and call APIs, so does the AI. A lot of people think (even I did back in 2023) that if you know how to make components, pass props, and call an API, you’re ready for backend. But I was wrong. React is not just about components, props, and API calls. I realized this when I got a frontend project from another developer. Everything looked fine. UI was good, backend was clean. But something felt off. Then I noticed the dependency array was not handled properly. The result? 100+ API calls on page load, and 429 errors started showing. There are no shortcuts to fundamentals. #javascript #frontenddevelopment #backenddevelopment #webdevelopment

🚀 Frontend Folder Structure That Scales A clean and well-organized frontend structure is not just about neat code — it’s about scalability, maintainability, and developer productivity. Here’s a structure I’ve found really effective while working on modern React/Next.js applications 👇 📁 api → Handles backend communication 📁 assets → Static files (images, icons, etc.) 📁 components → Reusable UI components 📁 context → Global state (Context API) 📁 data → Static/mock data 📁 hooks → Custom reusable logic 📁 pages → Application screens 📁 redux → Advanced state management 📁 services → Business logic & API handling 📁 utils → Helper functions 💡 Why this structure works: ✔ Improves code readability ✔ Makes scaling easier ✔ Encourages reusability ✔ Separates concerns clearly Whether you're building a small app or a large-scale product, structuring your frontend properly can save you hours of debugging and refactoring later. #Frontend #ReactJS #WebDevelopment #CleanCode #SoftwareEngineering #JavaScript #Programming

⚛️ 3 Common Mistakes Developers Make That Hurt React Performance While building React applications, I’ve noticed that performance issues often come from small architectural decisions rather than the framework itself. Here are three common mistakes developers make: 1️⃣ Unnecessary Re-renders Many components re-render more often than needed. This usually happens when state is lifted too high or when functions and objects are recreated on every render. ✔️ Using techniques like React.memo, useCallback, and useMemo can significantly reduce unnecessary renders. 2️⃣ Fetching Data Inefficiently Fetching data directly inside multiple components can cause duplicate API calls and slow down the application. ✔️ Using centralized data fetching, caching strategies, or tools like React Query can improve both performance and scalability. 3️⃣ Large Components Doing Too Much When a single component handles too many responsibilities, it becomes harder to optimize and maintain. ✔️ Breaking UI into smaller reusable components improves performance and keeps the codebase cleaner. Performance optimization in React is rarely about complex tricks — it’s usually about writing clean, predictable, and well-structured components.

🚀 Day 37— Managing Complex State with useReducer in React As React applications grow, managing state with simple hooks can become difficult to scale. Today I explored how React provides a powerful alternative through the useReducer hook for handling complex state logic in a predictable way. While useState works perfectly for simple updates, useReducer shines when state transitions depend on previous state or multiple actions. Here are the key concepts I learned today 👇 🔹 What is useReducer? useReducer is a hook used for advanced state management inside React components. It follows a pattern similar to Redux, but it is built directly into React, making it lightweight and easy to implement. This approach helps structure state updates in a clear and predictable manner. 🔹 Core Building Blocks 1️⃣ initialState Defines the starting value of the component’s state. Example: const initialState = { count: 0 }; 2️⃣ reducer(state, action) A pure function that determines how the state changes based on the action dispatched. Example logic: increment counter decrement counter reset state 3️⃣ The useReducer Hook Inside the component, useReducer connects the state with the reducer logic. const [state, dispatch] = useReducer(reducer, initialState); • state → current state value • dispatch() → sends actions to update the state 🧠 Why useReducer Matters Using the reducer pattern helps developers: • manage complex state transitions • keep update logic centralized • make components easier to debug and maintain • scale state management in larger components Moving from useState to useReducer feels like a major step toward writing structured and production-ready React code.

Ever built a Search Bar and noticed it always feels one step behind? ``` const [query, setQuery] = useState(""); const handleSearch = (e) => { setQuery(e.target.value); fetchResults(query); } ``` Your user types "React Hooks", but you're fetching results for "React Hook". Always one keystroke behind. This catches almost every React developer off guard at some point. I've had my fair share too when I was new to React. Here's what's actually happening under the hood: 1. User types -> setQuery is called -> React queues a re-render 2. The current function finishes executing (with the old value still in scope) 3. React re-renders the component 4. Only now does the useState return the new value of the state State updates in React are asynchronous. The setter doesn't mutate the variable in place - it schedules a new render where the updated value will be available. The fix is simpler than you'd think: ``` const handleSearch = (e) => { const newQuery = e.target.value; setQuery(newQuery); fetchResults(newQuery); } ``` Store the new value in a local variable first. Use that everywhere in the same function call. React's model makes much more sense once you stop thinking of state as a variable and start thinking of it as a snapshot per render. #ReactJS #React #Frontend #FrontendEngineering #WebDevelopment

I spent weeks building a beautiful UI that became a debugging nightmare. Here's why 👇 On my HerCycleBloom project, I did what a lot of new devs do , I built all the UI first, made everything look perfect, and left the backend and functionality for later. Big mistake. When it came time to wire everything up, errors started popping up across pages I'd already moved past. I was constantly going backwards, fixing things that should have been caught earlier. Time wasted. Momentum lost. What I do now instead: → Build one feature at a time, end to end → UI, logic, and backend together : before moving to the next section → Test as I go, not after everything is "done" Simple shift. Massive difference. Save yourself the headache — connect your layers as you build them. 🙏 GitHub : https://lnkd.in/dMKcsMfm #WebDevelopment #CodingTips #JuniorDeveloper #FullStackDevelopment #DevMistakes #LessonsLearned

"The future of scalable apps is Full-stack TypeScript with tRPC. Most teams aren't ready for it. 1. **Embrace Type Safety**: Use TypeScript for both front-end and back-end. This ensures that your contract between server and client isn’t just assumed; it’s guaranteed. 2. **Implement tRPC**: Build your API without schemas. tRPC provides end-to-end type safety by deriving types directly from your TypeScript code, a game changer for reducing errors. 3. **Skip REST and GraphQL Complexity**: Avoid manual type definitions and boilerplate. tRPC simplifies communication with fewer dependencies, making your stack more maintainable. 4. **Accelerate Development**: Try AI-assisted tooling to boost coding speed. It's perfect for rapidly prototyping with 'vibe coding' in TypeScript, letting you focus on logic rather than setup. 5. **Enhance Collaboration**: Share types across your team to eliminate the disconnect between front-end and back-end developers. This leads to fewer bugs and faster feature delivery. 6. **Debug Effortlessly**: With consistent types across your stack, trace issues in minutes, not hours. Your IDE becomes a powerhouse for preventing runtime errors with type hints. 7. **Stay Current**: Build on the latest versions of Node.js and TypeScript to leverage modern syntax and features. This keeps your tech stack up-to-date and efficient. ```typescript import { initTRPC } from '@trpc/server'; const t = initTRPC.create(); const appRouter = t.router({ getUser: t.procedure .input((val: unknown) => /* input validation */) .query(({ input }) => { return { id: input, name: "John Doe" }; // Example response }), }); ``` What challenges are you facing with full-stack TypeScript and tRPC integration?" #WebDevelopment #TypeScript #Frontend #JavaScript
