@longzai-intelligence-shared-kernel/mapper

Mapper 类型定义包，提供 ORM Mapper 和 Application Mapper 的统一接口类型。

安装

bun add @longzai-intelligence-shared-kernel/mapper

使用

ORM Mapper 接口

import type { OrmMapper } from '@longzai-intelligence-shared-kernel/mapper';

type UserOrmMapper = OrmMapper<UserEntity, UserOrmEntity>;

// 实现示例
class UserOrmMapperImpl implements UserOrmMapper {
  toDomain(orm: UserOrmEntity): UserEntity {
    // 转换逻辑
  }

  toOrm(entity: UserEntity): UserOrmEntity {
    // 转换逻辑
  }
}

Application Mapper 接口

import type { ApplicationMapper } from '@longzai-intelligence-shared-kernel/mapper';

type UserMapper = ApplicationMapper<UserEntity, UserDTO>;

// 实现示例
class UserMapperImpl implements UserMapper {
  toDTO(entity: UserEntity): UserDTO {
    // 转换逻辑
  }

  toDTOList(entities: UserEntity[]): UserDTO[] {
    return entities.map((entity) => this.toDTO(entity));
  }
}

API

OrmMapper<TDomain, TOrm>

ORM Mapper 接口类型，定义领域实体与 ORM 实体之间的双向转换契约。

| 方法 | 签名 | 说明 | | ---------- | --------------------------- | ------------------------- | | toDomain | (orm: TOrm) => TDomain | 将 ORM 实体转换为领域实体 | | toOrm | (entity: TDomain) => TOrm | 将领域实体转换为 ORM 实体 |

ApplicationMapper<TDomain, TDTO>

Application Mapper 接口类型，定义领域实体与 DTO 之间的转换契约。

| 方法 | 签名 | 说明 | | ----------- | --------------------------------- | ------------------------ | | toDTO | (entity: TDomain) => TDTO | 将领域实体转换为 DTO | | toDTOList | (entities: TDomain[]) => TDTO[] | 批量将领域实体转换为 DTO |
