Server Actions in Next.js allow you to write server-side mutation logic directly. You define async functions to handle form submissions and process data securely on the server without writing separate API routes.

Server Components fetch data and render statically on the server to reduce JavaScript bundle size, whereas Client Components handle interactive state and browser events. You manage their interaction to optimize performance.

Data fetching in async Server Components allows direct database access. Caching strategies store request results to optimize retrieval, while streaming progressively sends HTML to the client to improve load times.

Yes, you can secure your application using NextAuth.js with the App Router. It integrates with Next.js middleware to manage user sessions and protect specific routes from unauthorized access.

The best way to handle dynamic and parallel routes is using the App Router conventions. Dynamic routes use bracket syntax for URL parameters, while parallel routes use intercepting routes to render multiple pages simultaneously.

Yes, TypeScript works seamlessly with Next.js Server Components and Route Handlers. It enforces type safety for data fetching, component props, and API responses, ensuring robust backend logic and architecture.
