TypeORM

This Adapter is used to support SQL-flavored databases (like SQLite, MySQL, MSSQL, MariaDB, CockroachDB, etc.) through TypeORM, and mostly kept around for legacy reasons. (See the warning below.)

note

If you previously used this Adapter with MongoDB, check out the MongoDB Adapter instead.

danger

In the future, we might split up this adapter to support single flavors of SQL for easier maintenance and reduced bundle size.

Usage

To use this Adapter, you need to install the following packages:

npm install next-auth @next-auth/typeorm-legacy-adapter typeorm

Configure your Auth.js to use the TypeORM Adapter:

pages/api/auth/[...nextauth].js

import NextAuth from "next-auth"
import { TypeORMLegacyAdapter } from "@next-auth/typeorm-legacy-adapter"


export default NextAuth({
  adapter: TypeORMLegacyAdapter("yourconnectionstring"),
  ...
})

TypeORMLegacyAdapter takes either a connection string, or a ConnectionOptions object as its first parameter.

Custom models

The TypeORM adapter uses Entity classes to define the shape of your data.

If you want to override the default entities (for example to add a role field to your UserEntity), you will have to do the following:

This schema is adapted for use in TypeORM and based upon our main schema

1. Create a file containing your modified entities:

(The file below is based on the default entities)

lib/entities.ts

import {
  Entity,
  PrimaryGeneratedColumn,
  Column,
  ManyToOne,
  OneToMany,
  ValueTransformer,
} from "typeorm"

const transformer: Record<"date" | "bigint", ValueTransformer> = {
  date: {
    from: (date: string | null) => date && new Date(parseInt(date, 10)),
    to: (date?: Date) => date?.valueOf().toString(),
  },
  bigint: {
    from: (bigInt: string | null) => bigInt && parseInt(bigInt, 10),
    to: (bigInt?: number) => bigInt?.toString(),
  },
}

@Entity({ name: "users" })
export class UserEntity {
  @PrimaryGeneratedColumn("uuid")
  id!: string

  @Column({ type: "varchar", nullable: true })
  name!: string | null

  @Column({ type: "varchar", nullable: true, unique: true })
  email!: string | null

  @Column({ type: "varchar", nullable: true, transformer: transformer.date })
  emailVerified!: string | null

  @Column({ type: "varchar", nullable: true })
  image!: string | null

+ @Column({ type: "varchar", nullable: true })
+ role!: string | null

  @OneToMany(() => SessionEntity, (session) => session.userId)
  sessions!: SessionEntity[]

  @OneToMany(() => AccountEntity, (account) => account.userId)
  accounts!: AccountEntity[]
}

@Entity({ name: "accounts" })
export class AccountEntity {
  @PrimaryGeneratedColumn("uuid")
  id!: string

  @Column({ type: "uuid" })
  userId!: string

  @Column()
  type!: string

  @Column()
  provider!: string

  @Column()
  providerAccountId!: string

  @Column({ type: "varchar", nullable: true })
  refresh_token!: string | null

  @Column({ type: "varchar", nullable: true })
  access_token!: string | null

  @Column({
    nullable: true,
    type: "bigint",
    transformer: transformer.bigint,
  })
  expires_at!: number | null

  @Column({ type: "varchar", nullable: true })
  token_type!: string | null

  @Column({ type: "varchar", nullable: true })
  scope!: string | null

  @Column({ type: "varchar", nullable: true })
  id_token!: string | null

  @Column({ type: "varchar", nullable: true })
  session_state!: string | null

  @Column({ type: "varchar", nullable: true })
  oauth_token_secret!: string | null

  @Column({ type: "varchar", nullable: true })
  oauth_token!: string | null

  @ManyToOne(() => UserEntity, (user) => user.accounts, {
    createForeignKeyConstraints: true,
  })
  user!: UserEntity
}

@Entity({ name: "sessions" })
export class SessionEntity {
  @PrimaryGeneratedColumn("uuid")
  id!: string

  @Column({ unique: true })
  sessionToken!: string

  @Column({ type: "uuid" })
  userId!: string

  @Column({ transformer: transformer.date })
  expires!: string

  @ManyToOne(() => UserEntity, (user) => user.sessions)
  user!: UserEntity
}

@Entity({ name: "verification_tokens" })
export class VerificationTokenEntity {
  @PrimaryGeneratedColumn("uuid")
  id!: string

  @Column()
  token!: string

  @Column()
  identifier!: string

  @Column({ transformer: transformer.date })
  expires!: string
}

2. Pass them to TypeORMLegacyAdapter

pages/api/auth/[...nextauth].js

import NextAuth from "next-auth"
import { TypeORMLegacyAdapter } from "@next-auth/typeorm-legacy-adapter"
import * as entities from "lib/entities"

export default NextAuth({
  adapter: TypeORMLegacyAdapter("yourconnectionstring", { entities }),
  ...
})

Synchronize your database ♻

The synchronize: true option in TypeORM will generate SQL that exactly matches the entities. This will automatically apply any changes it finds in the entity model. This is a useful option in development.

Using synchronize in production

synchronize: true should not be enabled against production databases as it may cause data loss if the configured schema does not match the expected schema! We recommend that you synchronize/migrate your production database at build-time.

Naming Conventions

If mixed snake_case and camelCase column names are an issue for you and/or your underlying database system, we recommend using TypeORM's naming strategy feature to change the target field names. There is a package called typeorm-naming-strategies which includes a snake_case strategy which will translate the fields from how Auth.js expects them, to snake_case in the actual database.

For example, you can add the naming convention option to the connection object in your NextAuth config.

pages/api/auth/[...nextauth].js

import NextAuth from "next-auth"
import { TypeORMLegacyAdapter } from "@next-auth/typeorm-legacy-adapter"
import { SnakeNamingStrategy } from 'typeorm-naming-strategies'
import { ConnectionOptions } from "typeorm"

const connection: ConnectionOptions = {
    type: "mysql",
    host: "localhost",
    port: 3306,
    username: "test",
    password: "test",
    database: "test",
    namingStrategy: new SnakeNamingStrategy()
}

export default NextAuth({
  adapter: TypeORMLegacyAdapter(connection),
  ...
})
