Next.js 15 App Router enforces specific file-based routing conventions, using dedicated layout files and dynamic segment parameters to structure your project hierarchy. You organize your application by creating route files that automatically map to your URL paths.

Use Server Components by default for direct data fetching and static content, switching to Client Components only when requiring interactivity or browser APIs. This distinction ensures optimal rendering performance and adheres to React best practices.

Implement data fetching directly within Server Components for reads, use Server Actions for mutations, and configure Route Handlers for API endpoints. This strategy follows Next.js best practices for efficient data management and application performance.

Caching and revalidation mechanisms in Next.js 15 optimize data freshness and application performance. You configure these strategies to determine how fetched data is stored and when the server should revalidate the cached responses.

Next.js 15 middleware configuration fully supports TypeScript and integrates with React best practices. You configure middleware to intercept requests at the edge while maintaining type safety and following established App Router conventions.
