Constructors

constructor

• new MikroORM(options: Options<MySqlDriver, EM> | Configuration<MySqlDriver, EM>): MySqlMikroORM<EM>

• Inherited from MikroORM.constructor

  Parameters

  • options: Options<MySqlDriver, EM> | Configuration<MySqlDriver, EM>

  Returns MySqlMikroORM<EM>

Properties

readonlyinheritedconfig

config: Configuration<MySqlDriver, SqlEntityManager<MySqlDriver> & EntityManager<IDatabaseDriver<Connection>>>

Inherited from MikroORM.config

inheritedem

em: EM

Inherited from MikroORM.em

The global EntityManager instance. If you are using RequestContext helper, it will automatically pick the request specific context under the hood

Accessors

inheritedentityGenerator

• get entityGenerator(): IEntityGenerator

• Inherited from MikroORM.entityGenerator

  Shortcut for orm.getEntityGenerator()

  ---

  Returns IEntityGenerator

inheritedmigrator

• get migrator(): IMigrator

• Inherited from MikroORM.migrator

  Shortcut for orm.getMigrator()

  ---

  Returns IMigrator

inheritedschema

• get schema(): ReturnType<ReturnType<D[getPlatform]>[getSchemaGenerator]>

• Inherited from MikroORM.schema

  Shortcut for orm.getSchemaGenerator()

  ---

  Returns ReturnType<ReturnType<D[getPlatform]>[getSchemaGenerator]>

inheritedseeder

• get seeder(): ISeedManager

• Inherited from MikroORM.seeder

  Shortcut for orm.getSeeder()

  ---

  Returns ISeedManager

Methods

inheritedcheckConnection

• checkConnection(): Promise<{ ok: true } | { error?: Error; ok: false; reason: string }>

• Inherited from MikroORM.checkConnection

  Checks whether the database connection is active, returns .

  ---

  Returns Promise<{ ok: true } | { error?: Error; ok: false; reason: string }>

inheritedclose

• close(force?: boolean): Promise<void>

• Inherited from MikroORM.close

  Closes the database connection.

  ---

  Parameters

  • force: boolean = false

  Returns Promise<void>

inheritedconnect

• connect(): Promise<MySqlDriver>

• Inherited from MikroORM.connect

  Connects to the database.

  ---

  Returns Promise<MySqlDriver>

inheriteddiscoverEntities

• discoverEntities(): Promise<void>

• Inherited from MikroORM.discoverEntities

  Returns Promise<void>

inheriteddiscoverEntitiesSync

• discoverEntitiesSync(): void

• Inherited from MikroORM.discoverEntitiesSync

  Returns void

inheriteddiscoverEntity

• discoverEntity(entities: T | T[], reset?: string | string[]): void

• Inherited from MikroORM.discoverEntity

  Allows dynamically discovering new entity by reference, handy for testing schema diffing.

  ---

  Parameters

  • entities: T | T[]

  • optionalreset: string | string[]

  Returns void

inheritedgetEntityGenerator

• getEntityGenerator(): T

• Inherited from MikroORM.getEntityGenerator

  Gets the EntityGenerator.

  ---

  Returns T

inheritedgetMetadata

• getMetadata(): MetadataStorage
• getMetadata(entityName: EntityName<Entity>): EntityMetadata<Entity>

• Inherited from MikroORM.getMetadata

  Gets the MetadataStorage.

  ---

  Returns MetadataStorage

inheritedgetMigrator

• getMigrator(): T

• Inherited from MikroORM.getMigrator

  Gets the Migrator.

  ---

  Returns T

inheritedgetSchemaGenerator

• getSchemaGenerator(): SqlSchemaGenerator

• Inherited from MikroORM.getSchemaGenerator

  Gets the SchemaGenerator.

  ---

  Returns SqlSchemaGenerator

inheritedgetSeeder

• getSeeder(): T

• Inherited from MikroORM.getSeeder

  Gets the SeedManager

  ---

  Returns T

inheritedisConnected

• isConnected(): Promise<boolean>

• Inherited from MikroORM.isConnected

  Checks whether the database connection is active.

  ---

  Returns Promise<boolean>

inheritedreconnect

• reconnect(options?: Options): Promise<void>

• Inherited from MikroORM.reconnect

  Reconnects, possibly to a different database.

  ---

  Parameters

  • options: Options = {}

  Returns Promise<void>

staticinit

• init(options?: Options<D, EM>): Promise<MikroORM<D, EM>>

• Overrides MikroORM.init

  Initialize the ORM, load entity metadata, create EntityManager and connect to the database. If you omit the options parameter, your CLI config will be used.

  ---

  Parameters

  • optionaloptions: Options<D, EM>

  Returns Promise<MikroORM<D, EM>>

staticinitSync

• initSync(options: Options<D, EM>): MikroORM<D, EM>

• Overrides MikroORM.initSync

  Synchronous variant of the init method with some limitations:

  • database connection will be established when you first interact with the database (or you can use orm.connect() explicitly)
  • no loading of the config file, options parameter is mandatory
  • no support for folder based discovery
  • no check for mismatched package versions

  ---

  Parameters

  • options: Options<D, EM>

  Returns MikroORM<D, EM>
