Next.js 15 App Router uses file-based routing conventions to define layouts, loading states, and error handling. You create files in the app directory to map routes, implement Server Components, and manage data fetching strategies for dynamic web applications.

Server Actions in Next.js allow you to handle form submissions and data mutations directly on the server. You define asynchronous functions within Server Components to process form data, enabling efficient server-side rendering without creating separate API endpoints.

The best way to fetch data in Next.js Server Components is by implementing parallel and streaming data fetching strategies. This approach optimizes performance by fetching data directly on the server, reducing client-side JavaScript and leveraging server-first patterns.

Yes, you can build robust backend APIs and implement request middleware with the Next.js App Router. Middleware allows you to intercept requests before they complete, while API routes handle backend logic, ensuring secure and efficient web application development.

Next.js 15 provides metadata generation capabilities for Server Components. By exporting a metadata object from your route files, you can dynamically generate SEO metadata, ensuring your web application maintains optimal search engine visibility.
