Server components fetch data and render on the server by default, while client components require explicit directives to handle interactivity. You distinguish them by applying interleaving patterns to safely compose UI and establish correct component boundaries in your App Router project.

To handle async params and cookies in Next.js 15, you access them asynchronously within your App Router routes and route handlers. This approach replaces synchronous access methods from Next.js 14, ensuring data is correctly resolved before rendering or handling requests.

Migrating routing to the Next.js 15 App Router involves updating your route handlers to use async params and adjusting cookies and headers access. You align component usage with new app router guidelines and define required patterns for a smooth migration.

Configuring revalidation and metadata generation involves applying specific guidelines for App Router usage in production. You implement checks and recommendations to control data revalidation and dynamically generate metadata for your application routes.

Yes, Next.js 15 App Router patterns suit production deployment when you follow specific guidelines for revalidation and metadata generation. You apply defined patterns and deploy considerations to ensure correct component boundaries and stable performance.
