TypeORM - metadata

  @Entity('user')
  @Unique(['email'])
  class UserEntity {
    @PrimaryColumn({ type: 'uuid' })
    id: string;

    @CreateDateColumn()
    created_at: Date;

    @UpdateDateColumn()
    updated_at: Date;

    @Column({ type: 'varchar', length: 64, comment: '이메일 주소' })
    email: string;
  }
