          }
        },
      }),
  ],
  controllers: [AppController],
})
export class AppModule {}

  @Get()
  async getHello() {
    const item = await this.connection.entityManager.findOne(...);
    return { item };
  }
}

      }),
  ],
  controllers: [AppController],
})
export class AppModule {}

import { Controller, Get, } from '@nestjs/common';
