Structure Next.js App Router components by defaulting to server components for data fetching, adding client components only when interactivity requires it. Split server and client boundaries to maximize performance and maintainability.

The best way to fetch data in Next.js is using default static fetching with ISR for cached performance. Switch to dynamic no-store options only when your component's interactivity requires fresh, real-time data.

Use client components in Next.js when you need interactivity, state, or browser APIs. Keep the rest of your application as server components to ensure optimal data fetching and rendering performance.

Organize Next.js App Router files using standard conventions for layouts, loading states, and error handling. Document route organization techniques and 404 handling to maintain clear component separation and structure.

Server actions in Next.js work by executing server-side mutations directly from components, integrated with standard routing conventions. They pair with metadata generation and image optimization to improve overall application performance.
