Next.js App Router projects use Server Components by default to minimize client JavaScript and simplify data fetching. You establish clear server-client boundaries and only opt into client components when interactive state is required.

Revalidation and caching with Next.js Server Actions require configuring explicit cache strategies for reliable mutations. You validate inputs on the server and trigger revalidation paths to ensure data consistency after updates.

Streaming and partial prerendering in Next.js App Router routes allow progressive HTML rendering to the client. This mechanism wraps route segments in Suspense boundaries to stream content as data resolves, improving initial load performance.

You configure generateMetadata for SEO optimization across Next.js routes by defining an asynchronous function in your route file. This function fetches dynamic data to inject titles and meta tags into the document output.

A Next.js production deployment checklist for App Router apps includes verifying server-client boundaries, validating SEO metadata generation, testing streaming behavior, and confirming revalidation strategies to ensure readiness and performance.

Yes, Next.js Server Actions work without adding complex client-side dependencies. They allow you to write server-side mutation logic directly that the client invokes, reducing the need for manual API route creation.
