After working on state, routing, and UI in earlier projects, I wanted to build something that depends on external data and real-time updates 🌍 Built a Weather App where you can search any city and get current conditions in a clean, responsive UI 🌦️ What this added for me 1. Working with API data instead of static state 2. Handling loading and error states properly 3. Keeping the UI clear even when data changes dynamically 📱 Stack: React, Vite, Tailwind CSS, Vercel 🔗 Live: https://lnkd.in/gZGcnUFS 💻 Code: https://lnkd.in/gasfj-vK Still building and improving, open to feedback or connections 👍 #React #JavaScript #FrontendDevelopment #WebDevelopment #BuildInPublic #LearningInPublic #API #Vite #TailwindCSS #DevCommunity #TechCareers #SoftwareDevelopment Error Makes Clever

Modern React apps often need to work with data that lives outside React: browser APIs, global stores, or third-party libraries. That’s exactly where useSyncExternalStore comes in. It’s a specialized hook that lets you safely subscribe to external data sources — while staying compatible with React’s concurrent rendering and avoiding bugs like inconsistent UI state (“tearing”). What is useSyncExternalStore? useSyncExternalStore connects your component to an external store and keeps it in sync. Instead of managing state inside React (useState, useEffect), you: - subscribe to changes - read the current snapshot - let React re-render when data updates const value = useSyncExternalStore(subscribe, getSnapshot); Where: - subscribe → tells React how to listen for changes - getSnapshot → returns current data - optional getServerSnapshot → for SSR React will re-render only when the external value actually changes. useSyncExternalStore is not a “daily hook” — but when you need it, nothing else fits as well. #react #frontend #webdev #javascript #reactjs #hooks

⚡ A Simple React Performance Trick: Lazy Loading Components One performance issue I’ve noticed in many React applications is large bundle sizes. When an app loads too much JavaScript upfront, it can slow down the initial page load and impact user experience. One simple solution for this is Lazy Loading. Instead of loading all components at once, we can load them only when they are needed. Here’s a simple example 👇 import React, { lazy, Suspense } from "react"; const Dashboard = lazy(() => import("./Dashboard")); function App() { return ( <Suspense fallback={Loading...}> ); } What’s happening here? 🔹 React.lazy() loads the component only when it is rendered 🔹 Suspense shows a fallback UI while the component is loading 🔹 This reduces the initial bundle size Why this matters 👇 ✅ Faster initial page load ✅ Better performance for large applications ✅ Improved user experience This technique becomes especially useful for: • Dashboards • Admin panels • Large feature modules • Route-based components 💡 One thing I’ve learned while working with React: Small performance optimizations like lazy loading and code splitting can make a big difference as applications scale. Curious to hear from other developers 👇 Do you use lazy loading in your React applications? #reactjs #frontenddevelopment #javascript #webdevelopment #reactperformance #softwareengineering #coding

I recently developed a Medium-inspired blog platform using React.js, focusing on building a clean, scalable, and user-friendly application. The project emphasizes modern frontend practices such as dynamic routing, reusable component architecture, and efficient state management. 🔹 Key Highlights: • Implemented dynamic routing for blog listing and detailed views • Designed a responsive and accessible UI using Tailwind CSS • Managed global application state using Context API • Integrated REST APIs for fetching and rendering real-time data • Built protected routes and handled authentication using LocalStorage 🔹 Tech Stack: React.js • Tailwind CSS • React Router • Context API • Axios • LocalStorage This project strengthened my understanding of building structured React applications and handling real-world UI and data flow challenges. I am actively exploring more advanced concepts to build production-ready web applications. #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #SoftwareDevelopment

Most React developers are still thinking in a client-first way — and that’s becoming a problem. Server-first React is quietly changing how we build applications. The traditional approach: - Fetch in useEffect - Move data through APIs (JSON) - Render on the client This is no longer the default in modern React + Next.js. What’s changing: - Server Components handle data and rendering - Client Components are used only for interactivity - UI can be streamed directly from the server - Hydration is selective, not global Impact: - Less JavaScript sent to the browser - Reduced reliance on client-side state - Better performance by default - Simpler data flow (often without an extra API layer) A useful mental model: Server = data + structure Client = interaction This isn’t just a feature update - it’s a shift in architecture. If you’re still using useEffect primarily for data fetching, it may be time to rethink how your React apps are structured. #React #Frontend #Fullstack #JavaScript #WebDevelopment

Tackling State Management in React I recently wrapped up a multi-step form project and wanted to share the results. While it looks simple on the surface, keeping state synchronized across different views while ensuring a smooth user experience was a great challenge. Key features I focused on: Persistent State: Ensuring data isn't lost when moving between steps. Progress Tracking: A visual indicator to keep the user engaged. Building this helped me sharpen my React skills alongside my background in .NET. Check out the demo below! #ReactJS #DotNetDeveloper #WebDevelopment #Frontend #CodingLife

⚛️ You can finally delete <Context.Provider> 👇 For years, the Context API introduced a small but persistent redundancy. We defined a Context object, yet we couldn’t render it directly—we had to access the .Provider property every single time. ⚛️ React 19 removes this requirement. ❌ The Old Way: UserContext.Provider It often felt like an implementation detail leaking into JSX. Forget .Provider, and your app might silently fail or behave unexpectedly. ✅ The Modern Way: <UserContext> The Context object itself is now a valid React component. Just render it directly. Why this matters ❓ 📉 Less Noise — Cleaner JSX, especially with deeply nested providers 🧠 More Intuitive — Matches how we think: “wrap this in UserContext” 💡 Note: Note: <Context.Consumer> is also largely dead in favor of the use hook or useContext. Starting in React 19, you can render <SomeContext> as a provider. In older versions of React, use <SomeContext.Provider>. #React #JavaScript #WebDevelopment #Frontend #React19

Most devs think Server Components vs Client Components is about "where code runs." That's technically true. But it misses the point. After 3 years of building React apps, here's the mental model that finally clicked for me: 🖥️ Server Components = Your Data Layer Think of them as the backend of your frontend. They run on the server, can access databases directly, and ship ZERO JavaScript to the browser. Use them when: → Fetching data (no more useEffect waterfalls) → Reading env variables or secrets → Rendering static/heavy layouts 💻 Client Components = Your Interaction Layer These are classic React. They hydrate in the browser and handle ALL interactivity. Use them when: → You need state (useState, useReducer) → You need lifecycle hooks (useEffect) → You need event handlers (onClick, onChange) The mistake everyone makes? Thinking "Server = fast, Client = slow." Wrong. Server Components reduce your bundle. Client Components cache beautifully. The power is in MIXING them — not choosing one. Here's the real-world pattern I use: 📂 Server Component (layout + data fetching) └─ 💻 Client Component (interactive form) └─ 🖥️ Server Component (search results) Nest them. Compose them. Stop treating them like enemies. The mental shift: Server Components are not "better React." They're a different tool for a different job. Once you get this, Next.js App Router finally makes sense. #React #NextJS #WebDev #Frontend #ServerComponents

Scaling a Next.js application isn’t about writing more code—it’s about organizing it correctly from day one. Cluttering the app/ directory with business logic and UI components is a common mistake that inevitably leads to technical debt.
