Next.js App Router uses Server Components by default for data fetching and rendering. You should use Client Components only when you need interactivity, state, or browser APIs, ensuring efficient and maintainable React application development.

The best way to fetch data in Next.js App Router is directly inside Server Components. This approach leverages server-side execution, integrates seamlessly with caching and revalidation patterns, and avoids sending large payloads to the client.

Optimize Next.js performance by applying built-in techniques for image optimization and strategic bundle splitting. Separating Server and Client Components correctly also minimizes the JavaScript shipped to the browser, boosting overall application performance.

Yes, Next.js App Router supports advanced routing features including parallel routes and route groups. These principles allow you to build complex layouts and render multiple pages simultaneously within the same view.

Common Next.js anti-patterns include overusing Client Components for static data, bypassing built-in caching mechanisms, and improperly structuring API routes. Following App Router principles helps avoid these pitfalls to maintain scalable applications.
