import { BaseRepositoryService } from 'nestjs-mongo-crud-base';
import { Hero } from "../schemas/hero.schema";


@Injectable()

@ApiTags('heros')
@Controller('heros')
export class HeroController extends BaseController<Hero> {
  constructor(private readonly heroService: HeroService) {
    super(heroService)
  }
}

    },
    ...args: any[]
