# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project Overview

This is a uni-app Vue 3 + TypeScript swimming timer/training application called "智能秒表" (Smart Stopwatch). It supports multiple platforms including H5, WeChat mini-program, and native apps.

## Development Commands

```bash
# Development
npm run dev:h5              # Run H5 development server
npm run dev:mp-weixin       # Run WeChat mini-program development
npm run dev:app             # Run app development

# Build
npm run build:h5            # Build for H5
npm run build:mp-weixin     # Build for WeChat mini-program
npm run build:app           # Build for app

# Type checking
npm run type-check          # Run TypeScript type checking
```

```

### Service Layer Pattern
- `Service` class extends `BaseConfig` and provides:
  - API requests: `Service.Request(url, method, data)` - handles 401 token expiration automatically
  - Navigation: `Service.GoPage()`, `Service.GoPageTab()`, `Service.GoPageBack()`, `Service.GoPageDelse()`
  - Storage: `Service.SetStorageCache()`, `Service.GetStorageCache()`, `Service.DelStorageCache()`
  - Messages: `Service.Msg()`, `Service.Alert()`
  - Loading: `Service.LoadIng()`, `Service.LoadClose()`
  - File uploads: `Service.UpLoadMedia()`, `Service.uploadH5()`

### Pages Configuration
- Pages registered in `src/pages.json`
- User features in `subPackages` under `pages/userFunc/`
- Tab bar with 2 tabs: "项目" (index) and "我的" (user)
- Navigation style is custom for some pages (e.g., swimim page)

### Key Domain Types
- `Project`: Swimming project data (id, name, createdAt)
- `StudentRecord`: Student timing records
- `TimingState`: Timer state management
- `ResultData`: Standard API response wrapper

## Code Style

- Use tabs for indentation
- Single quotes for strings
- PascalCase for components and classes
- camelCase for variables and functions
- kebab-case for CSS classes
- Use `@/` path alias for imports from src/ directory
- Import Vue composition API from 'vue', uni-app hooks from `@dcloudio/uni-app`

## UI Framework

- **uview-plus** as primary UI component library (configured with easycom)
- **ColorUI** for CSS framework and icons
- Component prefix: `u-` (e.g., `<u-icon>`, `<u-button>`)
- Use `rpx` units for responsive design

## Important Notes

- Automatic 401 token handling: API requests through `Service.Request()` redirect to login on token expiration
- Clean up intervals in `onUnmounted()` lifecycle hook
- No test framework currently configured
- Platform-specific APIs prefixed with `uni.` (uni-app framework)
