What is a CDN

The pages and the app router can be used together in one Next.js project.

This might be helpful for incremental migration to the app router.

'use client' marks a boundary between the server and client code on the module dependency tree.

Every component imported in a file with 'use client' automatically becomes a client component.

We can still pass server components as props to the client components.
