The api uses the ORM Prisma and it needs the MongoDB instance to be a replica set.

If you use MongoDB Atlas, the set is managed for you.

The simplest way to run a replica set locally is to use the docker-compose file in /tools. First disable any running MongoDB instance on your machine, then run the docker-compose file.

cd tools
docker compose up -d

During development and testing, the api exposes the endpoint GET auth/dev-callback. Calling this will log you in as the user with the email foo@bar.com by setting the session cookie for that user.
