What is Prisma?

Prisma is an ORM for Typescript, that allows you to define your database schema and models in a schema.prisma file, and then generate a type-safe client that can be used to interact with your database from your backend.

Prisma Client

Located at /server/db/client.ts, the Prisma Client is instantiated as a global variable (as recommended as best practice by the team at Prisma) and exported to be used in your API routes.

Schema

You will find the Prisma schema file at /prisma/schema.prisma. This file is where you define your database schema and models, and is used when generating the Prisma Client.

With NextAuth.js

When you select NextAuth.js in combination with Prisma, the schema file is generated and set up for you with the recommended values for the User, Session, Account and VerificationToken models, as per the NextAuth.js documentation.

Default Database

The default database is a SQLite database, which is great for development and quickly spinning up a proof-of-concept, but not recommended for production. You can change the database to use by changing the provider in the datasource block to either postgresql or mysql, and then updating the connection string within environment variables to point to your database.
