Server vs Client Components

By default, all components in Next.js 15 are Server Components. Use the "use client" directive when you need client-side interactivity like state, effects, or browser APIs.

This architecture allows you to keep expensive computations and data fetching on the server while shipping minimal JavaScript to the client.
