A very basic sample of a separate next-auth authentication service that is meant to be hosted as a subdomain
The repo contains two projects, auth and client
auth runs on port 3000
client runs on port 8080
You will need to provide GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET environment variables for the auth project, or alternatively change the providers in [...nextauth].ts to use a different IDP
This was created to demonstrate the following discussion thread: nextauthjs/next-auth#2414 (comment)
