Async Configuration

To provide asynchronous mongoose schema options (similar to nestjs mongoose implementation) you can use the TypegooseModule.forRootAsync

@Module({
  imports: [
    TypegooseModule.forRootAsync({
      imports: [ConfigModule],
      useFactory: async (configService: ConfigService) => ({
        uri: configService.getString("MONGODB_URI")
        // ...typegooseOptions (Note: config is spread with the uri)
      }),
      inject: [ConfigService]
    })
  ]
})
export class CatsModule {}

Note: typegooseOptions with async

The typegooseOptions is spread with the uri. The uri is required!

You can also use a class with useClass

import {
  TypegooseOptionsFactory,
  TypegooseModuleOptions
} from "nestjs-typegoose";

class TypegooseConfigService extends TypegooseOptionsFactory {
  createTypegooseOptions():
    | Promise<TypegooseModuleOptions>
    | TypegooseModuleOptions {
    return {
      uri: "mongodb://localhost/nest"
    };
  }
}

@Module({
  imports: [
    TypegooseModule.forRootAsync({
      useClass: TypegooseConfigService
    })
  ]
})
export class CatsModule {}

Or if you want to prevent creating another TypegooseConfigService class and want to use it from another imported module then use useExisting

@Module({
  imports: [
    TypegooseModule.forRootAsync({
      imports: [ConfigModule],
      useExisting: ConfigService
    })
  ]
})
export class CatsModule {}
