## Common Patterns
|
||||
## 常见模式
|
||||
|
||||
### Frontend Patterns
|
||||
- **Component Composition**: Build complex UI from simple components
|
||||
- **Container/Presenter**: Separate data logic from presentation
|
||||
- **Custom Hooks**: Reusable stateful logic
|
||||
- **Context for Global State**: Avoid prop drilling
|
||||
- **Code Splitting**: Lazy load routes and heavy components
|
||||
### 前端模式
|
||||
- **组件组合 (Component Composition)**:从简单组件构建复杂 UI
|
||||
- **容器/展示组件 (Container/Presenter)**:分离数据逻辑与表现层
|
||||
- **自定义 Hooks**:可重用的有状态逻辑
|
||||
- **全局状态上下文 (Context for Global State)**:避免属性钻取(Prop drilling)
|
||||
- **代码分割 (Code Splitting)**:延迟加载路由和重型组件
|
||||
|
||||
### Backend Patterns
|
||||
- **Repository Pattern**: Abstract data access
|
||||
- **Service Layer**: Business logic separation
|
||||
- **Middleware Pattern**: Request/response processing
|
||||
- **Event-Driven Architecture**: Async operations
|
||||
- **CQRS**: Separate read and write operations
|
||||
### 后端模式
|
||||
- **存储库模式 (Repository Pattern)**:抽象数据访问
|
||||
- **服务层 (Service Layer)**:业务逻辑分离
|
||||
- **中间件模式 (Middleware Pattern)**:请求/响应处理
|
||||
- **事件驱动架构 (Event-Driven Architecture)**:异步操作

- **CQRS**:读写职责分离
|
||||
|
||||
### Data Patterns
|
||||
- **Normalized Database**: Reduce redundancy
|
||||
- **Denormalized for Read Performance**: Optimize queries
|
||||
- **Event Sourcing**: Audit trail and replayability
|
||||
- **Caching Layers**: Redis, CDN
|
||||
- **Eventual Consistency**: For distributed systems
|
||||
### 数据模式
|
||||
- **规范化数据库 (Normalized Database)**:减少冗余
|
||||
- **为读取性能去规范化 (Denormalized for Read Performance)**:优化查询
|
||||
- **事件溯源 (Event Sourcing)**:审计追踪与可重放性

## Architecture Decision Records (ADRs)
|
||||
## 架构决策记录 (Architecture Decision Records, ADRs)
|
||||
|

||||
Need to store and query 1536-dimensional embeddings for semantic market search.
|
||||
## 上下文 (Context)
|
||||

## Red Flags
|
||||
## 红线(反模式)
|
||||
|
||||
Watch for these architectural anti-patterns:
|
||||
- **Big Ball of Mud**: No clear structure
|
||||
- **Golden Hammer**: Using same solution for everything
|
||||
- **Premature Optimization**: Optimizing too early
|
||||
- **Not Invented Here**: Rejecting existing solutions
|
||||
- **Analysis Paralysis**: Over-planning, under-building
|
||||
- **Magic**: Unclear, undocumented behavior
|
||||
- **Tight Coupling**: Components too dependent
|
||||
- **God Object**: One class/component does everything
|
||||
警惕这些架构反模式:
|
||||
- **大泥球 (Big Ball of Mud)**:没有清晰的结构
|
||||
- **金锤 (Golden Hammer)**:用同一种方案解决所有问题
|
||||
- **过早优化 (Premature Optimization)**:优化得太早
|
||||
- **非我所创 (Not Invented Here)**:拒绝现有解决方案
|
||||
- **分析瘫痪 (Analysis Paralysis)**:过度规划,疏于构建
|
||||
- **魔法 (Magic)**:不清晰、无文档的行为
|
||||
- **紧耦合 (Tight Coupling)**:组件间过于依赖
|
||||
- **上帝对象 (God Object)**:一个类/组件完成所有事情
|
||||

AI 驱动的 SaaS 平台示例架构:
|
||||
|
||||
### Current Architecture
|
||||
- **Frontend**: Next.js 15 (Vercel/Cloud Run)
|
||||
- **Backend**: FastAPI or Express (Cloud Run/Railway)
|
||||
- **Database**: PostgreSQL (Supabase)
|
||||
- **Cache**: Redis (Upstash/Railway)
|
||||
- **AI**: Claude API with structured output

|
||||
### 当前架构
|
||||
- **前端**:Next.js 15 (Vercel/Cloud Run)
|
||||
- **后端**:FastAPI 或 Express (Cloud Run/Railway)
|
||||
- **数据库**:PostgreSQL (Supabase)
|
||||
- **缓存**:Redis (Upstash/Railway)
|
||||
- **AI**:具备结构化输出的 Claude API
|
||||
- **实时性**:Supabase 订阅(subscriptions)
|
||||
|
||||
### Key Design Decisions
|
||||
1. **Hybrid Deployment**: Vercel (frontend) + Cloud Run (backend) for optimal performance
|
||||
2. **AI Integration**: Structured output with Pydantic/Zod for type safety
|
||||
3. **Real-time Updates**: Supabase subscriptions for live data
|
||||
4. **Immutable Patterns**: Spread operators for predictable state
|
||||
5. **Many Small Files**: High cohesion, low coupling
|
||||
### 关键设计决策
|
||||
1. **混合部署**:Vercel(前端)+ Cloud Run(后端)以获得最佳性能
|
||||
2. **AI 集成**:结合 Pydantic/Zod 使用结构化输出以确保类型安全
|
||||
3. **实时更新**:使用 Supabase 订阅获取实时数据
|
||||
4. **不可变模式**:使用展开运算符(Spread operators)以实现可预测的状态
|
||||
5. **大量小文件**:高内聚,低耦合
|
||||
|
||||
### Scalability Plan
|
||||
- **10K users**: Current architecture sufficient
|
||||
- **100K users**: Add Redis clustering, CDN for static assets
|
||||
- **1M users**: Microservices architecture, separate read/write databases
|
||||
- **10M users**: Event-driven architecture, distributed caching, multi-region
|
||||
### 可扩展性计划
|
||||
- **1 万用户**:当前架构足够
|
||||
- **10 万用户**:增加 Redis 集群,为静态资源添加 CDN
|
||||
- **100 万用户**:微服务架构,分离读写数据库
|
||||
- **1000 万用户**:事件驱动架构,分布式缓存,多区域部署
|
||||
|
||||
**Remember**: Good architecture enables rapid development, easy maintenance, and confident scaling. The best architecture is simple, clear, and follows established patterns.
|
||||
**记住**:良好的架构能够实现快速开发、易于维护和自信的扩展。最好的架构是简单、清晰并遵循既定模式的。
