🧠 How I Structure React Apps for Real-Time Systems After working on dashboards handling live data (WebSockets, charts, 3D views), I realized one thing: 👉 Bad structure = unscalable app Here’s the architecture I follow 👇 📁 components/ Reusable UI (pure, presentational) 📁 pages/ Feature-level screens (Dashboard, Monitoring, etc.) 📁 hooks/ Custom hooks → data fetching, WebSocket logic 📁 services/ All API + WebSocket logic (NO direct calls in components) 📁 context/ or store/ Global state (selected rack, filters, etc.) 🔥 Data Flow: WebSocket/API → service → hook → component → UI 👉 Keeps everything predictable & testable ⚡ Real Insight: ❌ Mixing API calls inside components = chaos ❌ Too much global state = performance issues 👉 Keep logic layered and isolated 💡 From real-world dashboards: Handling real-time updates across multiple components becomes EASY when your architecture is clean. 🧠 Rule: 👉 “Components should render UI, not manage systems” If you’re building scalable React apps or real-time dashboards, this structure will save you from future headaches 🚀 #reactjs #frontenddevelopment #javascript #softwarearchitecture #webdevelopment #reactcontext #coding #reactpatterns

🚀 Understanding Controlled vs Uncontrolled Components in React — Simplified! Handling forms in React seems simple… until it’s not. Choosing between controlled and uncontrolled components can impact your app’s scalability, validation, and performance. 💡 What are Controlled Components? 👉 Form data is managed by React state const [name, setName] = useState(""); <input value={name} onChange={(e) => setName(e.target.value)} /> ✅ React is the source of truth ✅ Easy validation & control 💡 What are Uncontrolled Components? 👉 Form data is handled by the DOM itself const inputRef = useRef(); <input ref={inputRef} /> 👉 Access value when needed: inputRef.current.value ⚙️ How it works 🔹 Controlled: State-driven Re-renders on every change Full control over input 🔹 Uncontrolled: DOM-driven No re-render on input change Less control 🧠 Real-world use cases ✔ Controlled: Form validation Dynamic UI updates Complex forms ✔ Uncontrolled: Simple forms Performance-sensitive inputs Quick prototyping 🔥 Best Practices (Most developers miss this!) ✅ Prefer controlled components for scalability ✅ Use uncontrolled for simple or performance-heavy cases ✅ Avoid mixing both in the same form ❌ Don’t overuse uncontrolled in complex apps ⚠️ Common Mistake // ❌ Mixing both approaches <input value={name} ref={inputRef} /> 👉 Leads to unpredictable behavior 💬 Pro Insight Controlled = Predictability Uncontrolled = Simplicity 👉 Choose based on complexity vs performance needs 📌 Save this post & follow for more deep frontend insights! 📅 Day 5/100 #ReactJS #FrontendDevelopment #JavaScript #ReactHooks #WebDevelopment #SoftwareEngineering #100DaysOfCode 🚀

I got tired of rewriting the same scroll logic… so I built a reusable React hook 👇 In one of my projects, I had multiple places where I needed: → Detect when a user is near the bottom → Trigger API calls (pagination / infinite scroll) → Handle different containers (not just window scroll) Initially, I was repeating this logic everywhere. So I extracted it into a custom hook: 👉 useTableScrollPagination What it does: • Works with both containers and tables (AG Grid in my case) • Lets me control when to trigger (75%, 90%, etc.) • Prevents duplicate API calls while loading • Keeps scroll position intact after data updates The biggest win? 👉 I no longer think about scroll logic — I just reuse it. I know there are libraries for infinite scroll, but in real-world apps: → Custom containers → Complex UI structures → Different trigger behaviors …often need a more flexible approach. Curious — how are you handling infinite scroll in your apps? Library or custom solution? #ReactJS #FrontendDevelopment #TypeScript #DeveloperExperience

🚀 Understanding Conditional Rendering in React — Simplified! In real-world apps, UI is rarely static. 👉 Show loading 👉 Hide elements 👉 Display data conditionally That’s where Conditional Rendering comes in. 💡 What is Conditional Rendering? It allows you to render UI based on conditions. 👉 Just like JavaScript conditions—but inside JSX ⚙️ Common Ways to Do It 🔹 1. if/else (outside JSX) if (isLoggedIn) { return <Dashboard />; } else { return <Login />; } 🔹 2. Ternary Operator return isLoggedIn ? <Dashboard /> : <Login />; 🔹 3. Logical AND (&&) {isLoggedIn && <Dashboard />} 👉 Renders only if condition is true 🔹 4. Multiple Conditions {status === "loading" && <Loader />} {status === "error" && <Error />} {status === "success" && <Data />} 🧠 Real-world use cases ✔ Authentication (Login / Dashboard) ✔ Loading states ✔ Error handling ✔ Feature toggles ✔ Dynamic UI 🔥 Best Practices (Most developers miss this!) ✅ Use ternary for simple conditions ✅ Use && for single-condition rendering ✅ Keep JSX clean and readable ❌ Avoid deeply nested ternaries ❌ Don’t mix too many conditions in one place ⚠️ Common Mistake // ❌ Hard to read return isLoggedIn ? isAdmin ? <AdminPanel /> : <UserPanel /> : <Login />; 👉 Extract logic instead 💬 Pro Insight Conditional rendering is not just about showing UI— 👉 It’s about controlling user experience dynamically 📌 Save this post & follow for more deep frontend insights! 📅 Day 10/100 #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #ReactHooks #SoftwareEngineering #100DaysOfCode 🚀

241 package downloads in, and developers are already building real UI's with it. Here's everything I learned. I published a deep-dive on my blog at gwan.dev — a complete guide on pairing GWAN Design System with React Hook Form and Zod for bulletproof form validations. If you've ever written the same error state logic five times across five different inputs, this one's for you. What the article covers: → Setting up Zod schemas with TypeScript inference — write your validation once, get types for free → Wiring react-hook-form's register and formState directly into GWAN's Input, Checkbox, Select, and TextArea components → Displaying inline validation errors that respect GWAN's design tokens — consistent look across your entire app → Real-world patterns: async validation, dependent fields, and multi-step forms → How GWAN's controlled component API makes RHF integration feel native, not bolted on Why this stack works so well together: Zod gives you a single source of truth for your data shape. React Hook Form gives you performance. GWAN gives you the UI. None of them fight each other — they compose cleanly. The result is form code that's readable, maintainable, and looks good out of the box. 📖 Read the full guide: https://lnkd.in/gAnmSnRB 📦 Install GWAN: npm install gwan-design-system ⭐ 241 downloads and growing — thank you to everyone who's already using it. If you've built something with GWAN, I'd genuinely love to hear about it in the comments. If you like to contribute, I welcome your ideas in PRs. If you find the article useful, a share goes a long way for an indie open source project. 🙏 #ReactJS #NextJS #TypeScript #ReactHookForm #Zod #FormValidation #OpenSource #DesignSystem #WebDevelopment #FrontendEngineering #TailwindCSS

I built a simple To-Do app… and ended up redesigning how I think about UI. What started as a basic JavaScript project turned into a deep dive into: * Why directly manipulating the DOM breaks easily * Why data should be the single source of truth * How rendering from state** makes UI predictable * And how adding localStorage becomes trivial once architecture is right At first, my app worked — but it was fragile. Refreshing wiped data. UI and logic were tightly coupled. Every new feature felt harder. So I rebuilt it. Instead of “update DOM on events”, I switched to: 👉 Update data → Re-render UI from scratch That one shift changed everything. Then I added localStorage: 👉 Persist data → Load on startup → Render UI And suddenly, the app became consistent, predictable, and scalable. I also explored: * JavaScript execution phases (creation vs execution) * Event loop basics (why timing matters more than code order) * Why UI = function(state) is not just theory Below is a detailed video showcasing this project.
