auth

Setup

• Use docker compose up to initialize the app.

Prisma needs to perform transactions, which requires the MongoDB server to be run as a replica set. This is a case of multi-document transaction. Prisma cannot create a namespace in multi-document transaction. So, we have to manually create collections User, AuthorizationCode.

• Use docker compose exec mongo-primary mongo -u "<user>" -p "<password>" to interact with the mongodb shell.
• Instantiate the replica set as follows,
  • rs.initiate({"_id" : "authapp","members" : [{"_id" : 0,"host" : "mongo-primary:27017"},{"_id" : 1,"host" : "mongo-worker-1:27017"},{"_id" : 2,"host" : "mongo-worker-2:27017"},{"_id" : 3,"host" : "mongo-worker-3:27017"}]});
  • Set the priority of the master over the other nodes,
    conf = rs.config();
conf.members[0].priority = 2;
rs.reconfig(conf);
• Use use <dbname>; to switch to the required db, auth.
• Use db.createCollection('User'); to create a collection, User.
• Use db.createCollection('AuthorizationCode'); to create a collection, AuthorizationCode.

Setup is complete.
