Next.js App Router routing relies on file conventions like route groups, parallel routes, and intercepting routes. Apply these patterns alongside dedicated loading and error state files to structure dashboard pages and marketing sites without unnecessary client-side routing logic.

Handling caching and revalidation in Next.js requires a server-first rendering approach. Optimize bundle size and metadata generation by applying correct route file conventions and using server actions to trigger data revalidation for production-ready performance.

Optimizing Next.js bundle size and image handling involves enforcing server-first rendering and strict component boundaries. Keep interactive logic isolated in client components while leveraging server components for initial loads to minimize unnecessary JavaScript sent to the browser.

Yes, you can use server actions for API route handlers and metadata generation in Next.js. This pattern adheres to server-first workflows, allowing you to securely mutate data, validate inputs, and revalidate cached paths directly from your components or route handlers.
