Data fetching in Next.js App Router server components involves using the extended fetch API directly within the component to leverage automatic request memoization, caching, and on-demand revalidation for performant rendering.

The best way to implement dynamic routing in the Next.js App Router is by using nested folder structures with dynamic segments like [id] inside page.tsx files, allowing precise control over server-side data fetching and layout composition.

Use parallel and intercepting routes in Next.js when you need to render multiple route segments simultaneously or intercept standard navigation flow for modals, enabling advanced routing patterns within your App Router architecture.

Yes, the Next.js App Router supports Server Actions, allowing you to mutate data and handle form submissions directly on the server without creating separate API routes or client-side JavaScript.

Next.js middleware may not intercept requests correctly if the matcher configuration is misconfigured, so ensure your middleware logic accurately targets specific pathnames for proper request interception and routing optimization.
