Migrating from the Next.js Pages Router to the App Router involves adopting new file conventions, moving data fetching to server components, and updating metadata generation. This transition requires restructuring your routes and adapting to server-side rendering patterns.

Parallel routes and intercepting routes in Next.js allow advanced routing layouts like modals and split views. They use specific file conventions to render multiple pages simultaneously and intercept navigation to display contextual UI without losing the current route context.

Use server components in the Next.js App Router for static rendering, data fetching, and SEO benefits. Use client components when you need interactivity, state, hooks, or browser APIs, ensuring optimal component placement and rendering performance.

Streaming with Next.js server components enables progressive data rendering by sending UI chunks to the client as they become available. Implement loading states to provide immediate feedback while slower server-side data fetching operations complete in the background.

Yes, the Next.js App Router supports route handlers for building API endpoints and server actions for secure server-side data mutations. These features enable robust full-stack development directly within your Next.js application architecture.

Next.js 16 App Router caching strategies optimize data fetching and rendering performance through built-in request memoization and data caches. Metadata generation patterns use file conventions to dynamically generate SEO tags and titles directly from server components.
