Providers 싱글톤으로 사용하는 방법

NestJs에서 Providers(Service) 싱글톤으로 사용하는 방법

 

모듈을 Import 해서 사용하라!

 

 

 

You have to export the ItemsService in the module that provides it

@Module({
  controllers: [ItemsController],
  providers: [ItemsService],
  exports: [ItemsService]
})
export class ItemsModule {}

and then import the exporting module in the module that uses the service:

@Module({
  controllers: [PlayersController],
  providers: [PlayersService],
  imports: [ItemsModule]

})
export class PlayersModule {}

⚠️ Don't add the same provider to multiple modules. Export the provider, import the module
