# Working on the new api ## Connecting to local database The api uses the ORM Prisma and it needs the MongoDB instance to be a replica set. ### Atlas If you use MongoDB Atlas, the set is managed for you. ### Local 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. ```bash cd tools docker compose up -d ``` ## Login in development/testing 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.
