DDD 架構輔助技能
描述
確保前後端程式碼遵循 DDD 架構與 DAL 分離原則。
觸發條件
- 「建立新功能」「新增模組」
- 「架構檢查」
- 建立新檔案時自動檢查
- 「前端架構」「後端架構」
法規依據
- 憲法:CONSTITUTION.md 第 1、2 條
- 子法:.github/bylaws/ddd-architecture.md
🔧 後端 DDD 結構 (Python/Go/Rust)
新功能腳手架
當建立新功能時,自動生成 DDD 結構:
「新增 Order 領域」
生成:
src/
├── Domain/
│ ├── Entities/Order.py
│ ├── ValueObjects/OrderId.py
│ ├── Aggregates/OrderAggregate.py
│ └── Repositories/IOrderRepository.py
├── Application/
│ ├── UseCases/CreateOrder.py
│ └── DTOs/OrderDTO.py
└── Infrastructure/
└── Persistence/Repositories/OrderRepository.py
層級職責
| 層級 | 職責 | 可依賴 |
|---|---|---|
| Domain | 業務規則、Entity、Value Object | 無外部依賴 |
| Application | Use Case、DTO、編排 | Domain |
| Infrastructure | Repository 實作、外部 API | Domain |
| Presentation | API、CLI、UI | Application |
⚛️ 前端 DDD 結構 (React/Vue)
React 專案結構
「新增 User 管理功能 (React)」
生成:
src/
├── domain/
│ ├── models/
│ │ └── User.ts # Entity 類型定義
│ ├── types/
│ │ └── UserTypes.ts # Value Object 類型
│ └── rules/
│ └── userValidation.ts # 純業務規則(無框架依賴)
│
├── application/
│ ├── hooks/
│ │ └── useUser.ts # 業務邏輯 Hook
│ ├── stores/
│ │ └── userStore.ts # 狀態管理 (Zustand/Redux)
│ └── services/
│ └── UserService.ts # 應用服務(編排)
│
├── infrastructure/
│ ├── api/
│ │ └── userApi.ts # API Client (fetch/axios)
│ ├── storage/
│ │ └── userStorage.ts # LocalStorage/SessionStorage
│ └── adapters/
│ └── userAdapter.ts # API Response → Domain Model
│
└── presentation/
├── components/
│ └── UserCard.tsx # UI 元件
├── pages/
│ └── UserListPage.tsx # 頁面
└── layouts/
└── UserLayout.tsx # 佈局
Vue 3 專案結構
「新增 Product 管理功能 (Vue)」
生成:
src/
├── domain/
│ ├── models/
│ │ └── Product.ts
│ ├── types/
│ │ └── ProductTypes.ts
│ └── rules/
│ └── productValidation.ts
│
├── application/
│ ├── composables/
│ │ └── useProduct.ts # Composition API
│ ├── stores/
│ │ └── productStore.ts # Pinia Store
│ └── services/
│ └── ProductService.ts
│
├── infrastructure/
│ ├── api/
│ │ └── productApi.ts
│ └── adapters/
│ └── productAdapter.ts
│
└── presentation/
├── components/
│ └── ProductCard.vue
├── views/
│ └── ProductListView.vue
└── layouts/
└── ProductLayout.vue
前端層級對照
| 層級 | React | Vue 3 | 職責 |
|---|---|---|---|
| Domain | models/, types/, rules/ | 同左 | 純 TypeScript,無框架 |
| Application | hooks/, stores/ | composables/, stores/ | 業務邏輯封裝 |
| Infrastructure | api/, adapters/ | 同左 | 外部服務對接 |
| Presentation | components/, pages/ | components/, views/ | UI 元件 |
🔍 架構違規檢查
後端違規
偵測並警告:
- ❌ Domain 層導入 Infrastructure
- ❌ 直接在 Domain 操作資料庫
- ❌ Application 層直接操作資料庫
- ❌ Repository 實作放在 Domain 層
前端違規
偵測並警告:
- ❌ Domain 層導入 React/Vue(應為純 TypeScript)
- ❌ 元件直接呼叫 API(應透過 hooks/composables)
- ❌ 將業務邏輯寫在元件內
- ❌ API Response 直接用於 UI(應經過 adapter 轉換)
依賴方向驗證
✅ Presentation → Application → Domain
✅ Infrastructure → Domain (實作介面)
❌ Domain → Infrastructure
❌ Domain → Application
❌ Domain → React/Vue/框架
📋 檢查範本
後端輸出
🏗️ DDD 架構檢查 (Backend)
✅ 依賴方向正確
✅ DAL 正確分離
⚠️ 警告:
- src/Domain/Services/UserService.py:15
導入了 Infrastructure 模組
建議:
將資料庫操作移至 Repository
前端輸出
🏗️ DDD 架構檢查 (Frontend - React)
✅ Domain 層無框架依賴
✅ API 呼叫正確封裝於 infrastructure/
⚠️ 警告:
- src/presentation/components/UserCard.tsx:23
直接呼叫 fetch(),應使用 useUser hook
建議:
將 API 呼叫移至 src/application/hooks/useUser.ts
🎯 快速生成指令
「建立後端 Order 領域」 → 生成 Python DDD 結構
「建立前端 User 功能」 → 詢問 React/Vue,生成對應結構
「架構檢查」 → 掃描全專案違規
「前端架構檢查」 → 僅掃描前端
