+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Commands
+
+```bash
+# Development
+npm run dev          # Start Vite dev server
+npm run build        # Type-check and build for production
+npm run preview      # Preview production build
+```
+
+## Architecture Overview
+
+This is a Vue 3 + TypeScript AI chat UI application built with the following stack:
+
+**Core:**
+- Vue 3 (Composition API with `<script setup>`)
+- Pinia for state management
+- TypeScript with path alias `@/*` → `src/*`
+- Vite for build tooling
+
+**Styling:**
+- TailwindCSS 4 + UnoCSS (dual setup)
+- Custom SCSS for global styles
+- Dark mode support via `.dark` class
+
+**Key Dependencies:**
+- `markstream-vue` - Streaming markdown rendering
+- `lucide-vue-next` - Icon library
+- `@vueuse/core` - Vue composables utilities
+- `echarts`, `mermaid`, `shiki` - Visualization and code highlighting
+
+## Project Structure
+
+```
+src/
+├── components/       # Vue components organized by feature
+│   ├── chat/        # Main chat interface (ChatMain, ChatHeader, MessageList, WelcomeScreen)
+│   ├── message/     # Message rendering (MessageBubble, CodeBlock, ThinkingNode, etc.)
+│   ├── input/       # Chat input and attachments
+│   ├── sidebar/     # Conversation list sidebar
+│   ├── modals/      # Settings and search modals
+│   └── ui/          # Reusable form components
+├── stores/          # Pinia stores
+│   ├── chat.ts      # Conversation and message management
+│   └── settings.ts  # App settings and theme
+├── composables/     # Reusable composables (useKeyboard)
+├── services/        # API layer (api.ts - chat streaming, file upload)
+├── types/           # TypeScript type definitions
+└── utils/           # Helper functions
+```
+
+## State Management
+
+Two Pinia stores manage application state:
+
+**`useChatStore`** (`src/stores/chat.ts`):
+- Manages conversations (CRUD operations)
+- Handles message streaming state
+- Persists to localStorage
+
+**`useSettingsStore`** (`src/stores/settings.ts`):
+- App settings (theme, font size, preferences)
+- Sidebar state
+- Modal visibility controls
+- Persists to localStorage
+
+## API Layer
+
+`src/services/api.ts` defines the API contract. The backend must implement these endpoints:
+- `POST /api/chat-ui/chat` - Chat (streaming supported)
+- `GET /api/chat-ui/conversations` - List conversations
+- `POST /api/chat-ui/upload` - File upload
+- `GET /api/chat-ui/models` - Model list
+- `POST /api/chat-ui/stop/:id` - Stop generation
+
+## Development Notes
+
+- Base path configured as `/chat-ui/` in `vite.config.ts`
+- Proxy configured for `/api/chat-ui` → `http://localhost:3000`
+- UnoCSS shortcuts available: `flex-center`, `full`, and regex-based patterns
+- Toast notifications available globally via `window.$toast(message, type)`

+# 日志系统文档
+
+## 概述
+
+本项目实现了统一的后端日志系统，为所有接口提供了详细的日志记录功能，包括请求、响应、错误等状态。
+
+## 日志系统结构
+
+### 1. logger.js
+- 统一日志管理模块
+- 支持多种日志级别：ERROR, WARN, INFO, DEBUG
+- 支持控制台和文件双重输出
+- 包含HTTP请求专用日志方法
+
+### 2. 日志文件位置
+- 存储在 `server/logs/` 目录
+- 按日期命名：`server-YYYY-MM-DD.log`
+- JSON格式便于查询和分析
+
+## 日志级别
+
+- `ERROR`: 错误和异常情况
+- `WARN`: 警告和潜在问题
+- `INFO`: 重要操作和状态信息
+- `DEBUG`: 详细调试信息
+
+## 接口日志详情
+
+### 1. 对话接口 (`/api/chat-ui/chat`)
+- 记录请求代理开始和结束
+- 记录目标API响应状态
+- 记录代理错误
+
+### 2. 模型列表接口 (`/api/chat-ui/models`)
+- 记录请求基本信息
+- 记录返回的模型数量
+
+### 3. 对话管理接口 (`/api/chat-ui/conversations/*`)
+- 记录操作类型（获取/创建/删除）
+- 记录对话ID
+- 记录操作结果
+
+### 4. 文件上传接口 (`/api/chat-ui/upload`)
+- 记录上传文件信息（名称、大小、类型）
+- 记录上传结果和生成的URL
+
+### 5. 停止生成接口 (`/api/chat-ui/stop/*`)
+- 记录停止请求的ID
+- 记录操作结果
+
+### 6. HTTP通用日志
+- 记录所有请求的方法、URL、状态码
+- 记录请求耗时
+- 记录客户端IP和User-Agent
+- 根据状态码自动分类日志级别
+
+## 使用方法
+
+### 环境变量
+```bash
+LOG_LEVEL=DEBUG  # 设置日志级别，默认为INFO
+```
+
+### 在代码中使用
+```javascript
+const { logger } = require('./logger');
+
+logger.info('Some info message', { additional: 'data' });
+logger.error('Error occurred', { error: error.message });
+logger.debug('Debug info', { variable: value });
+```
+
+## 日志示例
+
+### HTTP请求日志
+```json
+{
+  "timestamp": "2026-03-03T03:26:58.631Z",
+  "level": "INFO",
+  "message": "HTTP GET /api/chat-ui/models 200 15ms",
+  "method": "GET",
+  "url": "/api/chat-ui/models",
+  "statusCode": 200,
+  "duration": "15ms",
+  "userAgent": "Mozilla/5.0...",
+  "ip": "::1"
+}
+```
+
+### 特定接口日志
+```json
+{
+  "timestamp": "2026-03-03T03:27:12.123Z",
+  "level": "INFO",
+  "message": "Successfully uploaded file",
+  "filename": "1642342342-file.jpg",
+  "originalName": "file.jpg",
+  "url": "http://localhost:3000/uploads/1642342342-file.jpg",
+  "size": 123456
+}
+```
