Next.js data fetching should use Server Components for direct database access, Server Actions for mutations, and Route Handlers for external API endpoints, ensuring efficient and maintainable data patterns.

React Server Component boundaries require careful separation of server and client logic, using directives appropriately to prevent invalid patterns and maintain optimal rendering performance.

Hydration errors in Next.js can be resolved by ensuring server-rendered HTML matches client output, using Suspense boundaries effectively, and following proper component hydration patterns.

Next.js image and font optimization involves using built-in components for automatic resizing, responsive loading, and font subsetting to improve application performance and loading speed.

Parallel and intercepting routes in Next.js are used for advanced routing patterns like modals and dynamic layouts, allowing simultaneous rendering of multiple route segments within a single view.

Error handling in Next.js requires implementing error boundaries for component-level failures and navigation error handling for route transitions, ensuring robust user experiences during failures.
