## DDD领域驱动设计的微服务前端案例
> 持续开发中及时拉取代码文档还不够完善先凑合看目前只是demo代码还会进行大规模封装细化和改造
搭建的一套**基于DDD领域驱动设计的微服务前端**,适用于大型企业,开发大型复杂且拓展灵活的前端应用的架构方案。
> 微服务架构中,前端用什么语言不受约束,随意就好!
项目大致技术栈:
- [DDD领域驱动设计](https://zh.wikipedia.org/zh-cn/%E9%A0%98%E5%9F%9F%E9%A9%85%E5%8B%95%E8%A8%AD%E8%A8%88)
- [@originjs/vite-plugin-federation](https://www.npmjs.com/package/@originjs/vite-plugin-federation)
- [Deno](https://deno.com/)
- [TypeScript](https://www.typescriptlang.org/)
- [GraphQL](https://graphql.org/)
- [docker](https://www.docker.com/)
- [drone](https://drone.cool/)
- [nginx](https://nginx.org/)
- [Vue3](https://cn.vuejs.org/)
- [Jsx](https://legacy.reactjs.org/docs/introducing-jsx.html)
- [Vite](https://cn.vite.dev/)
- [axios](https://axios-http.com/)
- 等等等....
## 开发任务
- [x] 基于DDD理念改造
- [ ] 基于 vite-plugin-federation 拆分领域模块为联邦模块,实现微前端
- [ ] 领域模块实现 docker自动化构建部署上线
- [ ] Deno集成GraphQL

# Fresh project
Your new Fresh project is ready to go. You can follow the Fresh "Getting
Started" guide here: https://fresh.deno.dev/docs/getting-started
### Usage
Make sure to install Deno:
https://docs.deno.com/runtime/getting_started/installation
Then start the project in development mode:
```
deno task dev
```
This will watch the project directory and restart as necessary.

### 依赖注意
DDD 中允许 “外层依赖内层”(交付层依赖领域层),但不允许 “内层依赖外层”。
- 正确features交付层 → domains领域层
- 错误domains领域层 → features交付层
#### 避免类型重复定义
如果不在视图中直接使用领域类型,就需要在交付层重新定义一套类似的类型(如 “视图专用商品类型”),这会导致:
- 代码冗余和不一致风险
- 类型转换的额外成本
- 业务规则分散(领域层的类型约束可能在视图层被忽略)
### 横切关注点 ### 横切关注点
- 特征:横向,影响多个模块,那些无法放入任何一个业务模块,而是会"横着"贯穿多个甚至所有模块的技术性需求。 - 特征:横向,影响多个模块,那些无法放入任何一个业务模块,而是会"横着"贯穿多个甚至所有模块的技术性需求。

* 优点:是一个依赖工厂,它隐藏了对象创建的细节,
* 让业务代码只需要关心 “做什么”,而不用关心 “依赖从哪里来”
* 所有依赖关系都在di目录下集中配置一目了然后续维护时能快速找到所有依赖的创建逻辑。
*
* 松耦合:
* 业务代码ProductApplicationService只依赖抽象接口ProductRepository
* 不依赖具体实现。如果未来需要改用其他数据来源(比如 WebSocket
* 只需修改bindProductRepository的返回值无需改动业务逻辑。
*
* 易于测试:
* 测试时可以临时替换为模拟实现
* productModule.bindProductRepository = () => new MockProductRepository();
