Optimistic UI for Perceived Performance

⚡ Your React App is Slow? Here’s What Actually Matters Most developers focus on features. Top developers focus on performance. Here’s what I use in real projects 👇 🚀 Techniques: React.memo → prevent unnecessary re-renders useCallback & useMemo → optimize heavy functions Lazy loading → reduce initial bundle size Code splitting → faster load time Example 👇 const MemoComponent = React.memo(({ data }) => { return <div>{data}</div>; }); 💡 Real Impact: Faster UI ⚡ Better user experience Improved Lighthouse score Performance is a feature. #ReactPerformance #WebPerformance #Frontend

One thing I’ve learned while building my app: Good structure doesn’t matter at the beginning… but it matters a lot as your project grows. On the backend, I naturally structured things like this: → routes → schemas → services Each layer had a clear responsibility. Easy to scale. Easy to maintain. But on the frontend, I went with: → components → hooks → lib It felt clean at first. Until the app started growing (boards, pins, collaborators…). Working on a single feature meant jumping across multiple folders: components → hooks → lib Same feature… different places. That’s when I realized: I was structuring my backend by feature logic, but my frontend by file type. And that difference becomes very obvious at scale. So I’m now moving toward a more feature-based structure on the frontend: → grouping everything related to a feature in one place Not a full refactor yet, but the direction is clear. Key takeaway: You don’t really understand structure when starting a project, you understand it when the project starts growing. Curious how others approach this ….do you prefer feature-based or layer-based structure? #softwareengineering #webdevelopment #reactjs #nextjs #buildinpublic

Week 35 – Understanding Rendering Strategies in Next.js This week, I spent time understanding how Next.js actually delivers content to users and it completely changed the way I think about building web apps. My key learnings: ✅ SSR (Server-Side Rendering) – Rendering pages on each request when fresh data matters ✅ SSG (Static Site Generation) – Pre-building pages for speed and performance ✅ ISR (Incremental Static Regeneration) – Updating static pages without rebuilding everything What stood out to me is that it’s not just about building features anymore—it’s about how those features are delivered. The same app can feel completely different depending on the rendering strategy you choose. This week made me realize that performance and scalability aren’t afterthoughts—they’re decisions you make early while building. Step by step, I’m moving closer to thinking like a developer who builds not just working apps, but efficient ones. Looking forward to experimenting more with these strategies in real projects as I continue my #MERNStack journey. 🚀 #NextJS #ReactJS #WebDevelopment #FullStackDevelopment #CodingJourney #LearnInPublic #ProfessionalGrowth

🚨 Still structuring your Next.js routes like it’s 2022? If your folder structure is leaking into your URLs, you’re missing out on one of the cleanest features in Next.js: Route Groups. They let you organize your app by features, teams, or sections—without polluting your URL paths. That means: ✔️ Cleaner, user-friendly URLs ✔️ Better project organization ✔️ Easier scalability as your app grows ✔️ Flexible layouts without breaking routes Imagine keeping /about instead of /marketing/about while still organizing everything neatly behind the scenes. That’s the power. 💡 Pro tip: Use route groups for things like (auth), (dashboard), or (settings) to keep your codebase clean and maintainable. Start thinking structure-first, not URL-first. #NextJS #WebDevelopment #Frontend #ReactJS #CleanCode #SoftwareEngineering #DevTips

What if I told you that loading less can actually make your app faster? It sounds counterintuitive, but in the world of React, lazy loading and code splitting are the game changers. Imagine working late, pushing to meet a deadline. Your app loads sluggishly, and every second feels like an eternity. 🚀 Frustrating, right? But then you stumble upon lazy loading. You realize that instead of loading everything at once, you can break it down! 🎉 By prioritizing essential resources, your users experience lightning-fast load times. It’s like flipping a switch—no more waiting, just instant engagement. After diving into code splitting, you see the transformative effects: smaller bundles lead to improved performance across the board. 📦 Less JavaScript means faster rendering, smoother interactions, and happier users. The best part? Your app becomes more efficient as it only serves what’s needed when it’s needed. 🌟 Have you tried lazy loading or code splitting in your projects? What results did you see?

Day 10 - Frontend Diaries 👉 I thought React automatically optimizes everything While working with React, it’s easy to assume that it handles performance by default components re-render UI updates and everything just works But while building and observing behavior, I realized that React does not automatically optimize everything Unnecessary re-renders still happen props changes still trigger updates state changes can affect multiple parts of the UI React gives you the tools but how you use them decides performance Understanding when components re-render and how data flows through them becomes important as the app grows That’s when I realized React does not optimize your app for you it helps you build it, but optimization is still your responsibility #frontenddevelopment #reactjs #webdevelopment #fullstackdeveloper #softwareengineering #buildinpublic #buildinpublic #developers

Good frontend boundaries are not about adding ceremony, they are about protecting clarity. When features, state, and UI concerns bleed into each other, small changes start causing surprising breakages in totally unrelated parts of the app. Clear boundaries give each part of the system a defined job, which makes the codebase easier to reason about, safer to change, and far more sustainable as the product grows. In that sense, boundaries are not constraints on speed, they are what make speed possible over time. #reactjs #frontend #developerexperience #scalability

Rendering in React is one of those things that looks simple… until it’s not. At first, it feels like: state changes → UI updates → done But as your app grows, rendering becomes the difference between a smooth experience and a laggy, frustrating one. If you’ve worked with React long enough, you’ve probably seen: Unnecessary re-renders Components updating when nothing changed Performance drops that are hard to trace A few fundamentals that changed how I approach rendering: Not everything needs to re-render Memoization is powerful when used correctly State placement matters more than you think Derived state can silently hurt performance React renders are cheap… until they aren’t The goal isn’t to stop renders completely It’s to render the right components at the right time for the right reasons Once you understand this, optimizing React apps becomes much more predictable Curious how others handle rendering optimization in large apps #ReactJS #Frontend #WebDevelopment #JavaScript #SoftwareEngineering #Performance #CleanCode #TechLeadership

New project completed! 🚀 Sharing my latest React build: a fully functional interactive calculator. For this app, I focused on applying core React best practices: 🔹 Modularization: Clean code splitting with reusable components (Button, Screen). 🔹 Hooks: State management for mathematical logic and input flow. 🔹 UI/UX: Clean and responsive styling for an intuitive user experience. Check out the video below to see it in action! I'll leave the link to the GitHub repository in the first comment. 👇 #ReactJS #Frontend #WebDevelopment #JavaScript #SoftwareEngineering

A client once told me, “Can you add more features? The app isn’t performing well.” At first, I thought the same - maybe we just needed more functionality. But when I looked deeper… the real problem wasn’t features. The app was: • Slow • Buggy • Hard to scale And the issue? 👉 Frontend architecture. Now, before adding anything new, I always fix the foundation first. Because a strong architecture doesn’t just improve performance - it makes everything else easier. If your app feels slow or messy, maybe it’s not the features… it’s the frontend. 💬 Have you faced this before?
