Next.js Best Practices for Server-Side Architecture

Today I explored one of the most important concepts in Next.js — Routing. Coming from React, I was used to handling routes manually using libraries like React Router. But Next.js makes this much simpler and more structured. 💡 Key learnings: In Next.js, folder structure defines routes page.js represents a route automatically Creating nested folders creates nested routes Dynamic routing using [id] makes it easy to handle dynamic pages Navigation is handled using the built-in <Link /> component 📂 Example: /app/about/page.js → /about /app/users/[id]/page.js → /users/1 This approach feels more intuitive and reduces boilerplate code compared to traditional routing. I’m currently building my understanding step-by-step and will soon start implementing these concepts in a SaaS dashboard project. 🔁 Consistency > Perfection #NextJS #FrontendDevelopment #ReactJS #WebDevelopment #LearningInPublic #JavaScript #Developers #CodingJourney

I just built my first project with Next.js — and I finally understand why so many developers are switching to it. Coming from React, I used to think Next.js was just “React with extra steps”… but actually building with it changed everything. Things that stood out immediately: • Built-in routing (no more manual setup) • Server-side rendering out of the box • Better performance and SEO without extra configuration • Cleaner project structure What surprised me the most wasn’t just the features — it was how much faster I could build something that actually feels production-ready. This project pushed me to think differently about: Data fetching Performance optimization Structuring scalable apps If you're already comfortable with React, learning Next.js is honestly one of the best upgrades you can make right now. Still learning, still improving and open for collaboration — but this is a solid step forward 🚀 live demo : https://lnkd.in/d4C-jHY2 #NextJS #WebDevelopment #Frontend #React #JavaScript #BuildInPublic

👨💻 Day 2 of sharing what I’m learning Everyone says: “Learn React.” But in 2026, the real shift is happening around React. Here’s what’s changing 👇 🔹 React is becoming more backend-aware With Server Components, a part of your UI now runs on the server—not just the browser 🔹 Next.js is becoming the default choice Routing, API handling, SSR, optimization—everything in one place ⚡ 🔹 Performance is a priority, not an afterthought Less client-side JS, faster loads, better UX 🔹 Rendering strategies matter now CSR vs SSR vs SSG vs ISR—knowing when to use what is a real skill 🔹 Frontend ≠ just UI anymore You’re expected to think about data fetching, caching, and architecture 💡 My takeaway: Learning React alone isn’t enough anymore. Understanding how React fits into a full system is what makes you stand out. Right now, I’m focusing on: ✔ Building with Next.js ✔ Understanding Server Components ✔ Improving performance in small projects 👉 Are you still using plain React or have you moved to Next.js? #ReactJS #NextJS #WebDevelopment #Frontend #FullStack #LearningInPublic #Developers

Honestly, I didn't even realise how bad it was until the client pointed it out. "The dashboard is too slow. Users are leaving." That message hit different. 😅 We were so focused on shipping features that performance had taken a back seat. Classic mistake. So I sat down, opened DevTools and started digging. What I found was embarrassing honestly 😄 Here's what was wrong and how we fixed it 1. Everything was re-rendering. Constantly. Components re-rendering on every state change even when nothing relevant changed. We hadn't used useMemo or useCallback properly. I know — basic stuff. But in the rush of delivery, it just slips. Fixed it. Immediate difference. ⚡ 2. We were loading everything on the first paint Every single route, every feature, every component — all loading upfront. No code splitting at all. React.lazy + Suspense fixed this. Only load what the user needs right now. Should have done this from day one honestly. 3. A list rendering 500+ items at once Every item in the DOM at the same time. The browser was struggling and honestly so were we 😄 react-window saved us here. Virtual scrolling — only renders what's visible. Felt like a completely different app instantly. 4. useEffect was firing API calls like crazy Duplicate requests. Unnecessary fetches. Stale data everywhere. We thought it was a backend issue for two days. It wasn't. It was us. 😅 A proper custom useFetch hook with correct dependency arrays fixed everything. One clean pattern across the whole codebase. 5. Images. Nobody had touched them. Full size images loading on every page. Not a single one optimised. When I saw this I actually laughed because it was such an easy fix we had completely ignored. next/image + lazy loading. Done. 🚀 The result? 6 seconds → under 2 seconds load time. Client happy. Neha happy. Team finally sleeping properly 😄 The lesson I took from this — performance is not something you fix at the end. It's something you think about from the very first component you write. If your React app feels slow right now — start with these 5 things. I promise one of them is the culprit. #ReactJS #WebPerformance #FrontendDevelopment #JavaScript #NextJS #TypeScript #React #SoftwareEngineering #WebDevelopment #FrontendEngineer

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

The biggest shift in my frontend journey wasn’t learning a new syntax—it was completely changing my mental model. 🧠 When I first started working with React, shifting from imperative DOM manipulation to a declarative, component-driven approach felt like learning to write with my opposite hand. I had to stop thinking about how to change the UI, and start thinking about what the UI should look like for any given state. Now? I can’t imagine building web applications any other way. Here are three reasons React continues to be a staple in my tech stack: 1️⃣ Component Reusability: Building a robust design system and reusing logic across applications saves an incredible amount of time. 2️⃣ The Ecosystem: Whether it's Next.js for SSR, Zustand for state management, or Tailwind for styling, the tooling built around React is unmatched. 3️⃣ Continuous Evolution: From Class Components to Hooks, and now Server Components, the core team is never afraid to push the boundaries of what the web can do.

⚛️ React works with ⚡ Vite in a modern frontend setup. Earlier, I thought building React apps always required heavy bundling and slow refresh. But Vite changes that completely by using native ES modules. Instead of bundling everything at the start, Vite loads only what is needed — making development much faster and smoother. What I understood from this architecture: • ⚡ Instant dev server startup (no waiting time) • 🔁 Hot Module Replacement (see changes instantly without reload) • 🧩 Clear flow: index.html → main.jsx → App.jsx → components • 🧠 Easy-to-manage component-based structure • 📦 Optimized production build with better performance For beginners, this kind of setup reduces confusion and improves learning speed. For developers, it improves productivity and code quality. Understanding tools like Vite is not just about speed — it’s about writing better, scalable frontend applications. 🚀 #React #Vite #FrontendDevelopment #Learning #WebDevelopment #JavaScript

NestJS vs. Express.js: Which should you choose in 2026? 🚀 Stop me if you’ve heard this: "Express is too messy for large teams," or "NestJS is just over-engineered overkill." The truth? Both are incredible, but they solve different problems. Here is the 60-second breakdown: 🔪Express.js: The Minimalist’s Knife 🔹Vibe: Unopinionated and flexible. 🔹Best for: Small-to-medium apps, micro-services, and rapid prototyping. 🔹Pros: Tiny learning curve, total freedom, and massive community support. 🔹Cons: As the app grows, you have to "invent" your own architecture (which often leads to spaghetti code). 🏗️ NestJS: The Architect’s Blueprint 🔹Vibe: Structured, opinionated, and enterprise-ready. 🔹Best for: Large-scale applications, complex business logic, and growing teams. 🔹Pros: Out-of-the-box TypeScript, Dependency Injection, and modular architecture (inspired by Angular). 🔹Cons: Steeper learning curve and more boilerplate for tiny tasks. The Verdict: Choose Express if you want to move fast and have a small, disciplined team. Choose NestJS if you want a system that stays maintainable 3 years from now.

🚀 Understanding React Routing (Simplified) Just created this quick visual to break down React Routing concepts in a clean and structured way. Here’s the core idea 👇 🔹 Types of Routing Declarative → Uses predefined components Data / Custom → Build your own logic Framework → Full control from scratch 🔹 Declarative Routing (Most Common) Uses BrowserRouter Works with Context API Routes defined using <Route> Nested routes handled with <Outlet /> UI-first approach (render first, fetch later) 🔹 Key Concept Routing is basically about showing UI based on URL (path). 🔹 Nested Routing Parent component contains <Outlet /> Child routes render inside that space 🔹 When to Use What? Declarative → Best for most apps (simple, fast, scalable) Custom/Data routing → Useful for complex, dynamic apps 💡 Simple takeaway: Start with declarative routing. Master it. Then explore advanced routing patterns. Trying to turn my handwritten notes into clean visuals like this to improve clarity.
