@auth/typeorm-adapter

Official TypeORM adapter for Auth.js / NextAuth.js.

Installation​

npm install @auth/typeorm-adapter typeorm

TypeORMAdapter()​

TypeORMAdapter(dataSource, options?): Adapter

Setup​

Configure Auth.js to use the TypeORM Adapter:

pages/api/auth/[...nextauth].js
import NextAuth from "next-auth"
import { TypeORMAdapter } from "@auth/typeorm-adapter"

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

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

Advanced usage​

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
}
  1. Pass them to TypeORMAdapter
pages/api/auth/[...nextauth].js
import NextAuth from "next-auth"
import { TypeORMAdapter } from "@auth/typeorm-adapter"
import * as entities from "lib/entities"

export default NextAuth({
  adapter: TypeORMAdapter("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 { TypeORMAdapter } from "@auth/typeorm-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: TypeORMAdapter(connection),
  ...
})

Parameters​

▪ dataSource: string | DataSourceOptions

▪ options?: TypeORMAdapterOptions

Returns​

Adapter

TypeORMAdapterOptions​

This is the interface for the TypeORM adapter options.

Properties​

entities​

entities?: __module;

The TypeORM entities to create the database tables from.
