+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is the GFast UI project, a Vue 3 admin management system based on the vue-next-admin template, customized for a digital advertising/trading platform.
+
+## Commands
+
+- `npm install` - Install dependencies (use `npm install --registry=https://registry.npmmirror.com` for China mainland)
+- `npm run dev` - Start development server
+- `npm run build` - Build for production
+- `npm run lint` - Run ESLint check
+- `npm run lint-fix` - Fix ESLint issues automatically
+- `npm run type-check` - Run TypeScript type checking
+- `npm run quality` - Run both lint and type-check
+
+## Architecture Overview
+
+**Tech Stack:**
+- Vue 3 with Composition API (script setup)
+- TypeScript
+- Vite
+- Element Plus (UI framework)
+- Pinia (state management)
+- Vue Router (with hash mode)
+- Axios (HTTP client)
+- i18n (internationalization)
+- mitt (event bus)
+
+**Directory Structure:**
+- `src/api/` - API client methods organized by business domain (ads, assets, cid, customerService, digitalHuman, knowledge, login, menu, settings, system, etc.)
+- `src/components/` - Reusable Vue components
+- `src/directives/` - Custom Vue directives
+- `src/i18n/` - Internationalization configuration
+- `src/layout/` - Main layout components
+- `src/router/` - Route configuration
+  - `index.ts` - Router setup and guard
+  - `backEnd.ts` - Backend-controlled route initialization
+  - `frontEnd.ts` - Frontend-controlled route initialization
+  - `route.ts` - Static route definitions
+- `src/stores/` - Pinia state stores
+  - `themeConfig.ts` - Theme and global configuration
+  - `userInfo.ts` - User information
+  - `routesList.ts` - Dynamic route management
+  - `keepAliveNames.ts` - keep-alive cache management
+- `src/theme/` - Theme related styles
+- `src/types/` - TypeScript type definitions
+- `src/utils/` - Utility functions
+  - `request.ts` - Axios instance with interceptors, error handling, and token management
+  - `storage.ts` - Session storage wrapper
+  - `gfast.ts` - GFast-specific helpers (file URL construction, tree building, date formatting)
+  - `diffUtils.ts` - Field change detection for PUT requests
+- `src/views/` - Page components organized by business module
+
+**Key Patterns:**
+
+1. **Routing**: Supports both frontend and backend controlled routing. When backend control is enabled (`isRequestRoutes: true` in themeConfig), routes are fetched from the backend and dynamically added.
+
+2. **API Requests**:
+   - API methods are organized by domain in `src/api/` (each subdomain has its own directory structure)
+   - The Axios instance in `src/utils/request.ts` automatically:
+     - Adds Bearer token from session storage
+     - Sends only changed fields for PUT requests (diff comparison with original data)
+     - Handles token expiration globally with redirect to login
+     - Provides error message extraction from multiple response formats (`message`, `msg`, `error`, `detail`)
+     - Supports error mode configuration via `requestOptions.errorMode`:
+       - `global`: (default) Global error popup with backend message
+       - `page`: No automatic popup, reject the error for page-level handling
+       - `silent`: Completely silent, no error display
+     - Special handling for `code === 402`: Triggers module not enabled subscription flow (except for specific asset endpoints)
+   - Response format expects `code`, `message`/`msg`, and data. Known success codes: `0`, `200`.
+   - Use `getApiErrorMessage(error)` from `/@/utils/request` to extract user-friendly error messages in catch blocks when using `page` or `silent` mode.
+
+3. **Global Properties & Components**:
+   - Helpers registered globally for template use:
+     - `getUpFileUrl`, `handleTree`, `useDict`, `selectDictLabel`, `parseTime`, `getItems`, `setItems`, `getOptionValue`, `isEmpty`
+   - Global components:
+     - `pagination` - Reusable pagination component
+   - Global event bus via mitt: `app.config.globalProperties.mittBus`
+
+4. **Authentication**: Token is stored in session storage via the `Session` utility. 401 responses (HTTP or business code) trigger automatic logout.
+
+5. **Keep-alive**: Route components can be cached via keep-alive, managed by the `useKeepALiveNames` store.
+
+## Environment Variables
+
+- `.env.development` - Development environment settings
+- `.env.production` - Production environment settings
+- `VITE_API_URL` - Backend API base URL
+- `VITE_PORT` - Dev server port
+- `VITE_PUBLIC_PATH` - Public base path for production build
+- `VITE_OPEN_CDN` - Enable CDN for external dependencies
+
+## Development Notes
+
+- The project uses `/@` alias for `src/`
+- Components use the Composition API with `<script setup lang="ts">`
+- Styling is done with SCSS
+- ESLint enforces code quality
+- Node version requirement: `>=16.0.0` (supported: v16.x ~ v20.x)
