Prisma

You can also use NextAuth.js with the new experimental Adapter for Prisma. This version of the Prisma Adapter is not included in the core next-auth package, and must be installed separately.

info

You may have noticed there is a prisma and prisma-legacy adapter. This is due to historical reasons, but the code has mostly converged so that there is no longer much difference between the two. The legacy adapter, however, does have the ability to rename tables which the newer version does not.

To use this Adapter, you need to install Prisma Client, Prisma CLI, and the separate @next-auth/prisma-adapter package:

npm install @prisma/client @next-auth/prisma-adapter
npm install prisma --save-dev

Configure your NextAuth.js to use the Prisma Adapter:

pages/api/auth/[...nextauth].js
import NextAuth from "next-auth"
import Providers from "next-auth/providers"
import { PrismaAdapter } from "@next-auth/prisma-adapter"
import { PrismaClient } from "@prisma/client"

const prisma = new PrismaClient()

export default NextAuth({
providers: [
Providers.Google({
clientId: process.env.GOOGLE_CLIENT_ID,
clientSecret: process.env.GOOGLE_CLIENT_SECRET,
}),
],
adapter: PrismaAdapter(prisma),
})
tip

While Prisma includes an experimental feature in the migration command that is able to generate SQL from a schema, creating tables and columns using the provided SQL is currently recommended instead as SQL schemas automatically generated by Prisma may differ from the recommended schemas.

Schema for the Prisma Adapter (@next-auth/prisma-adapter)

Setup​

Create a schema file in prisma/schema.prisma similar to this one:

schema.prisma
generator client {
provider = "prisma-client-js"
}

datasource db {
provider = "sqlite"
url = "file:./dev.db"
}

model Account {
id String @id @default(cuid())
userId String
providerType String
providerId String
providerAccountId String
refreshToken String?
accessToken String?
accessTokenExpires DateTime?
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
user User @relation(fields: [userId], references: [id])

@@unique([providerId, providerAccountId])
}

model Session {
id String @id @default(cuid())
userId String
expires DateTime
sessionToken String @unique
accessToken String @unique
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
user User @relation(fields: [userId], references: [id])
}

model User {
id String @id @default(cuid())
name String?
email String? @unique
emailVerified DateTime?
image String?
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
accounts Account[]
sessions Session[]
}

model VerificationRequest {
id String @id @default(cuid())
identifier String
token String @unique
expires DateTime
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt

@@unique([identifier, token])
}

Generate Client​

Once you have saved your schema, use the Prisma CLI to generate the Prisma Client:

npx prisma generate

To configure your database to use the new schema (i.e. create tables and columns) use the prisma migrate command:

npx prisma migrate dev

To generate a schema in this way with the above example code, you will need to specify your database connection string in the environment variable DATABASE_URL. You can do this by setting it in a .env file at the root of your project.

As this feature is experimental in Prisma, it is behind a feature flag. You should check your database schema manually after using this option. See the Prisma documentation for information on how to use prisma migrate.
