Structure your Next.js 15 App Router project using file-based routing, layout conventions, and dynamic segments to ensure maintainable web application development. This approach organizes routes predictably within the file system.

Use Server Components for data fetching and static rendering, and Client Components for interactivity. Next.js 15 conventions dictate using Client Components only when state or browser APIs are explicitly required.

Fetch data in Next.js 15 by executing direct queries in Server Components, handling mutations via Server Actions, and processing external API requests through Route Handlers. These strategies ensure optimal data flow and performance.

Implement caching and revalidation in Next.js 15 using built-in mechanisms to control data freshness and performance. Configure revalidation strategies to balance optimal loading speed with up-to-date content delivery.

Next.js 15 App Router conventions fully support TypeScript for structured web application development. While TypeScript is highly recommended for type safety, the framework itself does not strictly mandate its usage.

Configure middleware in a Next.js 15 application by defining rules within the middleware file to intercept requests and apply authentication or routing logic. This ensures standardized request handling before route completion.
