Structure Server Components and Client Components in the Next.js App Router by applying server-first principles and colocation. Use Client Components only for user interaction, while keeping data fetching on the server.

The best way to fetch and cache data in Next.js 14 is by using Server Components for data fetching alongside targeted caching and revalidation strategies. This ensures efficient data management and scalable application performance.

Server Actions work in Next.js applications by executing server-side code directly from client components to handle mutations. They integrate with TypeScript to provide type-safe data modifications without creating separate API routes.

Yes, you can use parallel routes and layouts for dynamic routing in the App Router. This approach allows you to render multiple pages simultaneously within a shared layout, enabling complex UI patterns.

Use Route Handlers instead of Server Actions in Next.js when you need to expose external API endpoints or handle webhooks. Server Actions are better suited for direct client-side mutations and form submissions.

Streaming and error handling in Next.js Server Components work by progressively sending UI chunks to the client while isolating errors to specific route segments. This ensures the application remains responsive during data fetches.
