#Next.js#React#App Router#Tutorial
What is the App Router?
The App Router is Next.js 13+'s new routing system built on React Server Components. It provides:
- File-based routing with layouts
- Server Components by default
- Streaming and Suspense
- Built-in data fetching
Key Features
Server Components
Server Components run on the server, reducing JavaScript sent to the client. This improves performance and reduces bundle size.
Layouts
Layouts allow you to create shared UI that persists across routes. Perfect for headers, footers, and navigation.
Loading States
Built-in loading.tsx files make it easy to show loading states while data is being fetched.
Best Practices
When using the App Router:
- Use Server Components by default
- Add 'use client' only when needed
- Leverage layouts for shared UI
- Use streaming for better UX
