+# XSH Assistant 编码指南
+
+## 项目概览
+
+**xsh-assistant** 是一个基于 Nuxt 3 的 AI 驱动内容生成平台，专注于数字内容创作（微课视频、虚拟讲师、绿幕合成等）。核心特性：
+
+- **前端框架**: Nuxt 3 + Vue 3 + TypeScript + Tailwind CSS + Radix Vue UI
+- **状态管理**: Pinia（带持久化）
+- **媒体处理**: FFmpeg WASM（客户端视频处理）、WebAV（视频剪辑）
+- **API 集成**: 统一的 `useFetchWrapped` 包装器，所有请求都通过 `API_BASE` 代理（`https://service1.fenshenzhike.com/`）
+- **部署模式**: SPA（SSR=false）
+
+## 核心架构模式
+
+### 1. Composables 设计（Pinia + 自定义 Composables）
+
+**状态管理采用分层设计**：
+
+```
+Pinia Stores（持久化状态）
+├── useLoginState: 用户认证、token、个人资料
+├── useHistory: AIGC 会话、聊天历史
+└── useTourState: 新手引导状态
+
+业务 Composables（无状态或短生命周期）
+├── useFetchWrapped: API 请求包装（自动添加 token、user_id）
+├── useLLM: LLM API 调用（Spark 模型集成）
+├── useFFmpeg: FFmpeg WASM 单例管理
+├── useVideoBackgroundCompositing: 视频合成（数字人+背景）
+├── useVideoSubtitleEmbedding: 字幕嵌入
+└── useDownload: 文件下载管理
+```
+
+**关键模式**：
+- **Pinia stores 必须是单一实例**，通过 `storeToRefs()` 获取响应式引用
+- **API 请求必须通过 `useFetchWrapped`** 来自动处理认证头（token/user_id）
+- **FFmpeg 采用单例模式**（`useFFmpeg()` 返回全局加载的实例），避免重复初始化
+
+### 2. API 请求模式
+
+所有 API 请求使用统一的 `useFetchWrapped` 包装器：
+
+```typescript
+// 基础签名
+useFetchWrapped<RequestType, ResponseType>(action: string, payload?: RequestType, options?: FetchOptions)
+
+// 请求格式示例（来自 useHistory）
+useFetchWrapped<AuthedRequest, BaseResponse<resp.xxx>>(
+  'App.User_User.CheckSession',  // action 作为查询参数 ?s=
+  { token: loginState.token, user_id: loginState.user.id, ...payload },
+  { method: 'POST' }  // 默认 POST
+)
+```
+
+**约定**：
+- **每个请求必须包含** `token` 和 `user_id`（来自 `useLoginState`）
+- **响应结构统一**: `BaseResponse<T>` 包含 `ret: number` 状态码和 `data: T` 数据
+- **API_BASE 在 `nuxt.config.ts` 中定义**，所有请求都相对于此 URL
+
+### 3. 媒体处理架构
+
+#### FFmpeg 初始化流程
+- **单例加载**: 首次调用 `useFFmpeg()` 时初始化，后续复用缓存的实例
+- **WASM 资源加载**: 从 CDN（`cdn.jsdelivr.net`）加载 FFmpeg core、wasm、worker
+- **错误恢复**: 调用 `cleanupFFmpeg()` 清理资源并重置单例
+
+#### 视频合成流程（核心用例）
+```
+输入: 透明通道视频 (WebM) + 背景图 (PNG/File)
+  ↓
+1. 获取背景图尺寸
+2. 计算等比缩放到 720P
+3. 加载文件到 FFmpeg vFS
+4. 执行 FFmpeg 滤镜链：
+   - 背景: scale → ${outputWidth}x${outputHeight}
+   - 视频: scale → ${outputWidth}x${outputHeight} (保留 alpha)
+   - overlay: 视频叠加到背景（format=auto）
+5. 使用 VP9 编码（支持 alpha）+ Opus 音频编码
+6. 返回 Blob → 可直接上传或本地预览
+```
+
+### 4. UI 组件架构
+
+#### 内置组件库（`components/uni/`）
+自定义包装组件，提供统一 API：
+- `UniButton`: 按钮 + loading 状态
+- `UniInput`/`UniTextArea`: 表单输入
+- `UniSelect`: 下拉选择
+- `UniMessage`: 全局消息通知（通过 provide/inject）
+- `UniCopyable`: 可复制文本
+
+**消息通知用法**：
+```typescript
+const toast = useToast()  // Radix Vue 的 Toast（顶部通知）
+// 或从 provide 注入
+const messageApi = inject('uni-message')
+messageApi.success('操作成功')
+messageApi.error('操作失败', 5000)
+```
+
+#### Radix Vue + Nuxt UI 集成
+- 使用 Radix Vue for 基础组件（button, dialog, select）
+- Nuxt UI 用于高级组件 + 主题管理
+- **颜色方案**: primary='indigo', gray='neutral'，详见 `app.config.ts`
+
+### 5. 路由与页面结构
+
+**目录映射**：
+```
+pages/
+├── generation.vue (导航枢纽)
+└── aigc/
+    ├── chat/index.vue (聊天页，支持多 LLM 模型)
+    ├── draw/index.vue (绘图生成)
+    └── generation/
+        ├── course.vue (微课生成)
+        ├── green-screen.vue (绿幕视频)
+        ├── avatar-models.vue (数字讲师)
+        ├── materials.vue (片头片尾)
+        ├── ppt-templates.vue (PPT 库)
+        └── admin/ (管理功能)
+```
+
+**导航约定**：
+- `/generation` → 功能导航页面
+- `/aigc/chat` → 聊天/文本生成
+- `/generation/course` → 视频生成工作流
+- 所有生成功能都需要登录（ModalAuthentication 处理）
+
+## 开发工作流
+
+### 启动项目
+```bash
+ni                    # 安装依赖
+nr dev                # 启动 http://localhost:3000
+nr generate           # 生产构建 (生成静态文件)
+```
+
+### 常见任务
+
+**添加新的 API 端点**：
+1. 定义 Request 和 Response 类型（参考 `typings/llm.ts`）
+2. 在 composable 中使用 `useFetchWrapped` 调用
+3. 自动包含 token/user_id（来自 `useLoginState`）
+
+**添加新的视频处理功能**：
+1. 使用 `useFFmpeg()` 获取实例（自动初始化）
+2. 写入文件到 vFS: `ffmpeg.writeFile()`
+3. 执行命令：`ffmpeg.exec([...filterArgs])`
+4. 清理临时文件：`ffmpeg.deleteFile()`
+5. 使用 progress callback 通报处理进度
+
+**添加新的 UI 组件**：
+1. 创建在 `components/` 下（自动注册）
+2. 优先使用 Radix Vue + Nuxt UI（已集成）
+3. 使用 Tailwind CSS utility classes + `@apply` 指令
+4. 通过 `app.config.ts` 自定义 UI 主题
+
+## 项目特定的约定
+
+### 类型定义位置
+- **LLM 相关**: `typings/llm.ts`（ChatMessage, ChatSession, ModelTag, LLMModal）
+- **全局类型**: `typings/types.d.ts`（BaseResponse, AuthedRequest, UserSchema）
+- **组件接口**: 组件目录下的 `index.d.ts`（例 `components/aigc/drawing/index.d.ts`）
+
+### 命名规范
+- **Composables**: `use` 前缀（`useLoginState`, `useLLM`）
+- **Stores**: `use` + 功能名（`useHistory`, `useTourState`）
+- **组件**: PascalCase（`ChatItem.vue`, `ModalAuthentication.vue`）
+- **工具函数**: camelCase，放在 `composables/` 或各功能目录
+
+### 响应式数据模式
+- **Pinia store 返回值**: 必须通过 `storeToRefs()` 才能保持响应式
+- **模板中的 ref**: 直接访问（Vue 自动展开）
+- **跨组件数据**: 优先使用 Pinia store（带持久化）
+
+### 进度反馈与错误处理
+- **长时间操作** (视频处理): 通过 callback 函数报告 progress（0-100）
+- **错误处理**: 返回 Promise reject，上层 catch 处理；可选通过 toast/message 提示
+- **FFmpeg 错误**: 捕获 exitCode 非零，记录详细的 FFmpeg 输出
+
+## 依赖与性能优化
+
+### 关键依赖
+- **@ffmpeg/ffmpeg@0.12.15**: WASM 视频处理（从 CDN 加载）
+- **@webav/av-cliper**: 客户端视频剪辑库
+- **markdown-it + highlight.js**: 内容渲染（支持代码高亮）
+- **date-fns/dayjs**: 时间处理（dayjs-nuxt 提供全局实例）
+- **idb-keyval**: IndexedDB 简化操作（缓存大文件）
+
+### Vite 优化设置
+```typescript
+// nuxt.config.ts 中排除以下包进行优化，避免 bundling WASM
+optimizeDeps.exclude: ['@ffmpeg/ffmpeg', 'idb-keyval', '@webav/av-cliper', 'gsap', 'markdown-it']
+```
+
+### 构建排除项
+Worker 格式设置为 ES Module，避免 Vite 默认处理：
+```typescript
+vite.worker.format = 'es'
+```
+
+## 测试与调试
+
+- **开发服务器日志**: 浏览器控制台查看 FFmpeg、API、业务日志
+- **FFmpeg 调试**: `[FFmpeg]` 前缀的日志输出包含加载进度、命令执行信息
+- **状态调试**: Pinia DevTools（启用 `devtools: true`）
+- **样式调试**: Tailwind 配置在 `tailwind.config.ts`，按需自定义
+
+## 常见陷阱与解决方案
+
+| 问题 | 原因 | 解决方案 |
+|------|------|--------|
+| API 请求 401 | 缺少 token 或已过期 | 检查 `useLoginState().token`，通过 ModalAuthentication 重新登录 |
+| FFmpeg 加载超时 | CDN 资源加载慢 | 检查网络，可切换到本地 `/public/assets/ffmpeg` |
+| 视频输出无声音 | 滤镜链未映射音频 | 确保 FFmpeg 命令包含 `-map '1:a?'` 映射音频轨道 |
+| 组件未注册 | 文件位置错误 | 确保在 `components/` 目录下，子目录自动扁平化注册 |
+| Pinia 状态未持久化 | 未配置 persist 选项 | 在 store 返回语句后添加 persist 配置（参考 `useLoginState`） |
