To use Server Components and Client Components together in the Next.js App Router, you implement Server Components by default and explicitly designate Client Components using the "use client" directive. This architecture optimizes data fetching on the server while preserving client-side interactivity.

The best way to fetch and cache data in Next.js 14 is by utilizing the extended fetch API within Server Components. This approach supports fine-grained caching strategies and integrates seamlessly with streaming to progressively render UI as data becomes available.

To create a dynamic route with a slug parameter in Next.js, you generate a folder named with square brackets, such as [slug], inside the app directory. The slug parameter is then accessible within your page component for dynamic content rendering.

Yes, you can use Server Actions for form submissions and data mutations in Next.js 15. Server Actions allow you to write server-side mutation logic directly without creating dedicated API routes, streamlining full-stack data management.

Middleware in Next.js works by intercepting requests before they complete to protect routes and manage authentication. It allows you to verify user session tokens and conditionally redirect unauthorized access away from secured application areas.

Yes, you need to understand TypeScript to build production-grade Next.js applications. TypeScript is required to implement strongly typed Server Components, Route Handlers, and data fetching logic effectively across the full stack.
