## 1. 架构设计理念
|
||||
|
||||
### 1.1 设计目标
|
||||
|
||||
- **统一接口**：使用 Vercel AI SDK 统一不同 AI Provider 的接口差异
|
||||
- **动态导入**：通过动态导入实现按需加载，减少打包体积
|
||||
- **最小包装**：直接使用 AI SDK 的类型和接口，避免重复定义
|
||||
- **中间件增强**：扩大中间件的介入范围，覆盖请求的全生命周期（规划中）
|
||||
- **插件系统**：基于钩子的插件架构，支持请求全生命周期扩展
|
||||
- **类型安全**：利用 TypeScript 和 AI SDK 的类型系统确保类型安全
|
||||
- **轻量级**：专注核心功能，保持包的轻量和高效
|
||||
- **包级独立**：作为独立包管理，便于复用和维护
|
||||
|
||||
### 1.2 核心优势
|
||||
|
||||
- **标准化**：AI SDK 提供统一的模型接口，减少适配工作
|
||||
- **简化维护**：废弃复杂的 XxxApiClient，统一为工厂函数模式
|
||||
- **更好的开发体验**：完整的 TypeScript 支持和丰富的生态系统
|
||||
- **性能优化**：AI SDK 内置优化和最佳实践
|
||||
- **模块化设计**：独立包结构，支持跨项目复用
|
||||
- **可扩展中间件**：支持在请求全生命周期中插入自定义逻辑
|
||||
- **可扩展插件**：基于钩子的插件系统，支持灵活的功能扩展和流转换

### 4.4 增强的中间件系统 (规划中)
|
||||
### 4.4 钩子风格插件系统 ✅
|
||||
|
||||
扩展中间件架构，支持请求全生命周期的介入。
|
||||
基于钩子机制的插件架构设计，提供灵活的扩展系统。
|
||||
|
||||
**生命周期阶段：**
|
||||
1. **Pre-Request**：请求预处理、参数验证、缓存检查
|
||||
2. **Request**：实际的 AI SDK 调用
|
||||
3. **Stream Processing**：流式响应处理、实时转换
|
||||
4. **Post-Response**：响应后处理、结果聚合
|
||||
5. **Error Handling**：错误处理、重试、降级
|
||||
**钩子类型：**
|
||||
|
||||
**中间件分类：**
|
||||
1. **First Hooks**：执行到第一个有效结果就停止
|
||||
2. **Sequential Hooks**：按序链式执行，可变换数据
|
||||
3. **Parallel Hooks**：并发执行，用于副作用
|
||||
4. **Stream Hooks**：流转换，直接传递给 AI SDK
|
||||
|
||||
**生命周期中间件：**
|
||||
- `PreRequestMiddleware`：请求前处理，参数验证、权限检查
|
||||
- `PostResponseMiddleware`：响应后处理，结果转换、统计记录
|
||||
- `ErrorHandlingMiddleware`：错误处理，重试机制、降级策略
|
||||
- `CacheMiddleware`：缓存中间件，请求缓存、结果缓存
|
||||
**优先级系统：**
|
||||
|
||||
**核心中间件：**
|
||||
- `StreamProcessingMiddleware`：流式处理，chunk 转换、进度追踪
|
||||
- `RequestValidationMiddleware`：请求验证，schema 验证、安全检查
|
||||
- `ResponseTransformMiddleware`：响应转换，格式标准化、类型转换
|
||||
- `pre`：前置处理（-100 到 -1）
|
||||
- `normal`：标准处理（0 到 99）
|
||||
- `post`：后置处理（100 到 199）
|
||||
|
||||
**特性中间件：**
|
||||
- `ThinkingMiddleware`：思考过程中间件，记录推理步骤
|
||||
- `ToolCallMiddleware`：工具调用中间件，函数调用处理
|
||||
- `WebSearchMiddleware`：网络搜索中间件，集成搜索功能
|
||||
**核心钩子：**
|
||||
|
||||
**First Hooks (第一个有效结果)：**
|
||||
|
||||
- `resolveModel`：模型解析，返回第一个匹配的模型
|
||||
- `loadTemplate`：模板加载，返回第一个找到的模板
|
||||
|
||||
**Sequential Hooks (链式变换)：**
|
||||
|
||||
- `transformParams`：参数转换，依次变换请求参数
|
||||
- `transformResult`：结果转换，依次变换响应结果
|
||||
|
||||
**Parallel Hooks (并发副作用)：**
|
||||
|
||||
- `onRequestStart`：请求开始时触发
|
||||
- `onRequestEnd`：请求结束时触发
|
||||
- `onError`：错误发生时触发
|
||||
|
||||
**Stream Hooks (流转换)：**
|
||||
|
||||
- `transformStream`：流转换，返回 AI SDK 转换函数

## 6. 与现有架构的对比
|
||||
## 6. 简化设计原则
|
||||
|
||||
| 方面 | 现有架构 | 新架构 (AI Core 包) |
|
||||
|------|----------|-------------------|
|
||||
| **代码组织** | 集成在主应用中 | 独立包，模块化管理 |
|
||||
| **Provider 管理** | 各自独立的 XxxApiClient | 统一的 Provider 注册表 + 工厂 |
|
||||
| **接口标准化** | 手动适配各 Provider 差异 | AI SDK 统一接口 |
|
||||
| **类型安全** | 部分类型安全 | 完整的 TypeScript 支持 |
|
||||
| **维护成本** | 每个 Provider 需要单独维护 | 统一维护，新 Provider 快速接入 |
|
||||
| **包体积** | 所有 Provider 都打包 | 按需加载，动态导入 |
|
||||
| **复用性** | 仅限当前项目 | 可跨项目复用 |
|
||||
| **扩展性** | 添加新 Provider 复杂 | 只需在注册表中添加配置 |
|
||||
### 6.1 最小包装原则
|
||||
|
||||
## 7. 简化设计原则
|
||||
|
||||
### 7.1 最小包装原则
|
||||
- 直接使用 AI SDK 的类型，不重复定义
|
||||
- 避免过度抽象和复杂的中间层
|
||||
- 保持与 AI SDK 原生 API 的一致性
|
||||
|
||||
### 7.2 动态导入优化

# AI Core 插件系统
|
||||
|
||||
支持四种钩子类型：**First**、**Sequential**、**Parallel** 和 **Stream**。
|
||||
|
||||
## 🎯 设计理念
|
||||
|
||||
借鉴 Rollup/Vite 的成熟插件思想：
|
||||
|
||||
- **语义清晰**：不同钩子有不同的执行语义
|
||||
- **类型安全**：TypeScript 完整支持
|
||||
- **性能优化**：First 短路、Parallel 并发、Sequential 链式
|
||||
- **易于扩展**：`enforce` 排序 + 功能分类
|
||||
|
||||
## 📋 钩子类型
|
||||
|
||||
### 🥇 First 钩子 - 首个有效结果
|
||||
|
||||
```typescript
|
||||
// 只执行第一个返回值的插件，用于解析和查找
|
||||
resolveModel?: (modelId: string, context: AiRequestContext) => string | null
|
||||
loadTemplate?: (templateName: string, context: AiRequestContext) => any | null
|
||||
```
|
||||
|
||||
### 🔄 Sequential 钩子 - 链式数据转换
|
||||
|
||||
```typescript
|
||||
// 按顺序链式执行，每个插件可以修改数据
|
||||
transformParams?: (params: any, context: AiRequestContext) => any
|
||||
transformResult?: (result: any, context: AiRequestContext) => any
|
||||
```
|
||||
|
||||
### ⚡ Parallel 钩子 - 并行副作用
|
||||
|
||||
```typescript
|
||||
// 并发执行，用于日志、监控等副作用
|
||||
onRequestStart?: (context: AiRequestContext) => void
|
||||
onRequestEnd?: (context: AiRequestContext, result: any) => void
|
||||
onError?: (error: Error, context: AiRequestContext) => void
|
||||
```
|
||||
|
||||
### 🌊 Stream 钩子 - 流处理
|
||||
|
||||
```typescript
|
||||
// 直接使用 AI SDK 的 TransformStream
|
||||
transformStream?: () => (options) => TransformStream<TextStreamPart, TextStreamPart>
|
||||
```
|
||||
|
||||
## 🚀 快速开始
|
||||
|
||||
### 基础用法
|
||||
|
||||
```typescript
|
||||
import { PluginManager, createContext, definePlugin } from '@cherry-studio/ai-core/middleware'
|
||||
|
||||
// 创建插件管理器
|
||||
const pluginManager = new PluginManager()
|
||||
|
||||
// 添加插件
|
||||
pluginManager.use({
|
||||
name: 'my-plugin',
|
||||
async transformParams(params, context) {
|
||||
return { ...params, temperature: 0.7 }
|
||||
}
|
||||
})
|
||||
|
||||
// 使用插件
|
||||
const context = createContext('openai', 'gpt-4', { messages: [] })
|
||||
const transformedParams = await pluginManager.executeSequential(
|
||||
'transformParams',
|
||||
{ messages: [{ role: 'user', content: 'Hello' }] },
|
||||
context
|
||||
)
|
||||
```
|
||||
|
||||
### 完整示例
|
||||
|
||||
```typescript
|
||||
import {
|
||||
PluginManager,
|
||||
ModelAliasPlugin,
|
||||
LoggingPlugin,
|
||||
ParamsValidationPlugin,
|
||||
createContext
|
||||
} from '@cherry-studio/ai-core/middleware'
|
||||
|
||||
// 创建插件管理器
|
||||
const manager = new PluginManager([
|
||||
ModelAliasPlugin, // 模型别名解析
|
||||
ParamsValidationPlugin, // 参数验证
|
||||
LoggingPlugin // 日志记录
|
||||
])
|
||||
|
||||
// AI 请求流程
|
||||
async function aiRequest(providerId: string, modelId: string, params: any) {
|
||||
const context = createContext(providerId, modelId, params)
|
||||
|
||||
try {
|
||||
// 1. 【并行】触发请求开始事件
|
||||
await manager.executeParallel('onRequestStart', context)
|
||||
|
||||
// 2. 【首个】解析模型别名
|
||||
const resolvedModel = await manager.executeFirst('resolveModel', modelId, context)
|
||||
context.modelId = resolvedModel || modelId
|
||||
|
||||
// 3. 【串行】转换请求参数
|
||||
const transformedParams = await manager.executeSequential('transformParams', params, context)
|
||||
|
||||
// 4. 【流处理】收集流转换器（AI SDK 原生支持数组）
|
||||
const streamTransforms = manager.collectStreamTransforms()
|
||||
|
||||
// 5. 调用 AI SDK（这里省略具体实现）
|
||||
const result = await callAiSdk(transformedParams, streamTransforms)
|
||||
|
||||
// 6. 【串行】转换响应结果
|
||||
const transformedResult = await manager.executeSequential('transformResult', result, context)
|
||||
|
||||
// 7. 【并行】触发请求完成事件
|
||||
await manager.executeParallel('onRequestEnd', context, transformedResult)
|
||||
|
||||
return transformedResult
|
||||
} catch (error) {
|
||||
// 8. 【并行】触发错误事件
|
||||
await manager.executeParallel('onError', context, undefined, error)
|
||||
throw error
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 🔧 自定义插件
|
||||
|
||||
### 模型别名插件
|
||||
|
||||
```typescript
|
||||
const ModelAliasPlugin = definePlugin({
|
||||
name: 'model-alias',
|
||||
enforce: 'pre', // 最先执行
|
||||
|
||||
async resolveModel(modelId) {
|
||||
const aliases = {
|
||||
gpt4: 'gpt-4-turbo-preview',
|
||||
claude: 'claude-3-sonnet-20240229'
|
||||
}
|
||||
return aliases[modelId] || null
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### 参数验证插件
|
||||
|
||||
```typescript
|
||||
const ValidationPlugin = definePlugin({
|
||||
name: 'validation',
|
||||
|
||||
async transformParams(params) {
|
||||
if (!params.messages) {
|
||||
throw new Error('messages is required')
|
||||
}
|
||||
|
||||
return {
|
||||
...params,
|
||||
temperature: params.temperature ?? 0.7,
|
||||
max_tokens: params.max_tokens ?? 4096
|
||||
}
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### 监控插件
|
||||
|
||||
```typescript
|
||||
const MonitoringPlugin = definePlugin({
|
||||
name: 'monitoring',
|
||||
enforce: 'post', // 最后执行
|
||||
|
||||
async onRequestEnd(context, result) {
|
||||
const duration = Date.now() - context.startTime
|
||||
console.log(`请求耗时: ${duration}ms`)
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### 内容过滤插件
|
||||
|
||||
```typescript
|
||||
const FilterPlugin = definePlugin({
|
||||
name: 'content-filter',
|
||||
|
||||
transformStream() {
|
||||
return () =>
|
||||
new TransformStream({
|
||||
transform(chunk, controller) {
|
||||
if (chunk.type === 'text-delta') {
|
||||
const filtered = chunk.textDelta.replace(/敏感词/g, '***')
|
||||
controller.enqueue({ ...chunk, textDelta: filtered })
|
||||
} else {
|
||||
controller.enqueue(chunk)
|
||||
}
|
||||
}
|
||||
})
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
## 📊 执行顺序
|
||||
|
||||
### 插件排序
|
||||
|
||||
```
|
||||
enforce: 'pre' → normal → enforce: 'post'
|
||||
```
|
||||
|
||||
### 钩子执行流程
|
||||
|
||||
```mermaid
|
||||
graph TD
|
||||
A[请求开始] --> B[onRequestStart 并行执行]
|
||||
B --> C[resolveModel 首个有效]
|
||||
C --> D[loadTemplate 首个有效]
|
||||
D --> E[transformParams 串行执行]
|
||||
E --> F[collectStreamTransforms]
|
||||
F --> G[AI SDK 调用]
|
||||
G --> H[transformResult 串行执行]
|
||||
H --> I[onRequestEnd 并行执行]
|
||||
|
||||
G --> J[异常处理]
|
||||
J --> K[onError 并行执行]
|
||||
```
|
||||
|
||||
## 💡 最佳实践
|
||||
|
||||
1. **功能单一**：每个插件专注一个功能
|
||||
2. **幂等性**：插件应该是幂等的，重复执行不会产生副作用
|
||||
3. **错误处理**：插件内部处理异常，不要让异常向上传播
|
||||
4. **性能优化**：使用合适的钩子类型（First vs Sequential vs Parallel）
|
||||
5. **命名规范**：使用语义化的插件名称
|
||||
|
||||
## 🔍 调试工具
|
||||
|
||||
```typescript
|
||||
// 查看插件统计信息
|
||||
const stats = manager.getStats()
|
||||
console.log('插件统计:', stats)
|
||||
|
||||
// 查看所有插件
|
||||
const plugins = manager.getPlugins()
|
||||
console.log(
|
||||
'已注册插件:',
|
||||
plugins.map((p) => p.name)
|
||||
)
|
||||
```
|
||||
|
||||
## ⚡ 性能优势
|
||||
|
||||
- **First 钩子**：一旦找到结果立即停止，避免无效计算
|
||||
- **Parallel 钩子**：真正并发执行，不阻塞主流程
|
||||
- **Sequential 钩子**：保证数据转换的顺序性
|
||||
- **Stream 钩子**：直接集成 AI SDK，零开销
|
||||
|
||||
这个设计兼顾了简洁性和强大功能，为 AI Core 提供了灵活而高效的扩展机制。
