Mastering the Next.js App Router

Understanding Layouts

The App Router introduces nested layouts that prevent unnecessary re-renders.

With server components, you can fetch data directly on the server, improving performance and reducing client bundle size.

Dynamic Routing

Using folders like [slug], you can easily build blog systems.

Streaming and Suspense support allow smoother user experiences, especially when loading large datasets.

Next.js App Router is the future of React architecture.
