Use Server Components by default for data fetching and static content, switching to Client Components only for interactivity, state, and browser APIs. The App Router relies on this strategy to optimize initial load performance and reduce JavaScript bundle size.

Next.js data fetching patterns include default caching, revalidate for time-based revalidation, and no-store for dynamic real-time data. Fetch requests are automatically cached and deduplicated across the component tree, streamlining data flow.

Optimize Next.js performance by leveraging image optimization, analyzing bundle output, and using dynamic imports for lazy loading. These practices reduce initial JavaScript payloads and improve core web vitals for modern web applications.

Next.js App Router file conventions dictate route organization through nested folders and special files like page.tsx and layout.tsx. Best practices involve logically grouping route segments and isolating API routes for maintainable project structure.

Next.js caching strategies manage static and dynamic data Fetch requests, while server actions enable secure server-side data mutations. Correctly configuring these prevents common anti-patterns and ensures reliable application state.
