@sclable/nestjs-libs / es-cqrs / EventStoreAsyncOptions

Interface: EventStoreAsyncOptions

Asyncronous options for the event store

Example (useFactory): app.module.ts

@Module({
  imports: [
    ESCQRSModule.forRootAsync({
      inject: [GlobalOptionsProvider]
      useFactory: async (globalOptions: GlobalOptionsProvider) => {
        return await globalOptions.getEventStoreOptions()
      }
    }),
    MyModule,
  ]
})

Example (useClass / useExisting): app.module.ts

class OptionsFactory implements EventStoreOptionsFactory {
  public async createEventStoreOptions() {
    return { logging: true }
  }
}

@Module({
  imports: [
    ESCQRSModule.forRootAsync({
      useClass: OptionsFactory
    }),
    MyModule,
  ]
})

It is also possible to add additional imports for the options factory if the service required is in another module

Example (imports): app.module.ts

@Module({
  imports: [
    ESCQRSModule.forRootAsync({
      imports: [GlobalOptionsModule]
      inject: [GlobalOptionsProvider]
      useFactory: async (globalOptions: GlobalOptionsProvider) => {
        return await globalOptions.getEventStoreOptions()
      }
    }),
    MyModule,
  ]
})
