A Deno server handling requests with Cloud Auth looks like this.

npm create feathersdev@latest server --platform deno --app-id "<your-app-id>"

An authenticateRequest function that validates an incoming web standard request can be implemented in src/authenticate.ts like this:

<<< @/examples/server/deno/src/authenticate.ts

A Deno server can then use it in src/server.ts like this:

<<< @/examples/server/deno/src/server.ts

The full Deno example can be found here.
