To structure Next.js App Router components, default to server components for performance and SEO, strategically applying the 'use client' directive only when client-side interactivity is required. This ensures efficient client-server interaction and maintainable application architecture.

The best way to implement loading and error states in the Next.js App Router is by utilizing layout, loading, error, and not-found boundary files. This pattern provides robust UIs by managing expected delays and unexpected runtime errors across specific route segments.

Data fetching in the Next.js App Router leverages built-in caching mechanisms to optimize performance. By defaulting to server components, data fetching occurs on the server, allowing you to execute effective patterns that maximize caching efficiency and reduce client-side waterfall requests.

You should use server components by default for all data fetching and static rendering tasks in Next.js. Apply the 'use client' directive only when a component requires interactivity, state, or lifecycle methods, ensuring efficient client-server interaction and preserving SEO benefits.

Yes, the Next.js App Router fully supports TypeScript for defining component patterns. You can implement structured application architecture using TypeScript, ensuring type safety across server components, data fetching logic, and client-side UI boundaries.
