Introduction
Next.js takes React to the next level by providing everything needed to build production-ready applications. It combines performance, developer experience, and scalability into a single framework.
Think of Next.js as the operating system for modern web apps — managing routing, rendering, optimization, and deployment.
⚡ Why Next.js Matters
Next.js provides:
✅ Multiple Rendering Methods – SSR, SSG, ISR, and streaming ⚡ Automatic Optimization – images, fonts, scripts 🧠 Full-Stack Support – frontend, backend, APIs, and actions 📦 Built-in Routing – file-based and simple 🚀 Production Performance – fast loads and smooth UX
🧱 Core Concepts Concept Role App Router Modern routing system Server Components Server-rendered UI Client Components Interactive UI Data Fetching Server actions & fetch API Routes Backend endpoints Rendering Modes SSR, SSG, ISR Middleware Request handling Edge Functions Ultra-fast global execution 🛠 How Next.js Works
User requests a page Next.js determines rendering method Data is fetched on the server HTML is generated Client hydrates interactivity App becomes fully interactive
This happens in milliseconds.
🧩 Key Features
Hybrid rendering Built-in SEO optimization Automatic code splitting Image and font optimization Deployment-ready with Vercel
🔐 Best Practices
Use server components where possible Optimize images and fonts Structure your app clearly Leverage caching and revalidation Secure API routes and actions
🎯 Developer & Business Impact Developers
