- **App ID**: `wxf9ce8010f1ad24aa` (dev), `wx71ac9c27c3c3e3f4` (prod)

## Directory Structure

```

├── pages/              # Doctor-side main pages (医生端)
├── patient/pages/      # Patient-side pages (subpackage)
├── gift/pages/         # DTP pharmacy pages (subpackage)

└── config.ts           # Environment configs per appId
```

## Key Conventions

### Path Aliases

- `@/*` → `src/*` (configured in tsconfig.json and app.json `resolveAlias`)
- Use `@/utils/request` not relative paths

### User Types & Routing

Login types enforced in `app.ts`:

- `0`: Not logged in
- `1`: Patient (患者) → routes to `/patient/pages/*`
- `2`: Doctor (医生) → routes to `/pages/*`

Use `app.zdWaitLogin()` to guard pages that require login.

### Page/Component Wrappers

`app.ts` overrides global `Page` and `Component` with wrappers from `utils/page.ts` and `utils/component.ts`:

- Auto-sets `imageUrl` and `Timestamp` on page load
- Auto-handles navbar background on scroll
- Provides default share behavior

### Modal Colors (Required)

All `wx.showModal` must use:

```ts
wx.showModal({
  confirmColor: '#8c75d0',
  cancelColor: '#141515',
})
```

### App Instance (Required)

`getApp()` should be called at the top of the file, not inside methods:

```ts
// ✅ Correct
const app = getApp<IAppOption>()

Page({
  onLoad() {
    // Use app directly
    console.log(app.globalData)
  }
})

// ❌ Incorrect
Page({
  onLoad() {
    const app = getApp<IAppOption>()
    console.log(app.globalData)
  }
})
```

## WXML 开发规范

### 1. 不支持在 WXML 中直接调用方法

**错误示例：**

```xml
<!-- ❌ 错误：WXML 中不能直接调用方法 -->
<view>{{getUploadedCount()}}</view>
<view wx:if="{{hasPhotos()}}">内容</view>
```

**正确做法：**

```xml
<!-- ✅ 正确：使用数据绑定 -->
<view>{{uploadedCount}}</view>
<view wx:if="{{hasPhotos}}">内容</view>
```

```typescript
// 在 TS 中计算好数据
this.setData({
  uploadedCount: photos.length,
  hasPhotos: photos.length > 0
})
```

### 2. 列表渲染时使用 wx:key

```xml
<view wx:for="{{list}}" wx:key="id">{{item.name}}</view>
```

### 3. 条件渲染

```xml
<view wx:if="{{condition}}">显示</view>
<view wx:else>隐藏</view>
```

### 4. WXML 表达式限制

WXML 中的双大括号 `{{}}` 只能使用简单的表达式，**不支持**以下语法：

**❌ 不支持的语法：**

```xml
<!-- 方法调用 -->
<view>{{arr.indexOf(item) > -1}}</view>

<!-- 复杂表达式 -->
<view>{{obj.method().property}}</view>

<!-- 正则表达式 -->
<view>{{str.match(/regex/)}}</view>

<!-- new 操作符 -->
<view>{{new Date().getTime()}}</view>
```

**✅ 支持的语法：**

```xml
<!-- 简单属性访问 -->
<view>{{item.name}}</view>

<!-- 三元表达式 -->
<view class="{{item.isActive ? 'active' : ''}}">内容</view>

<!-- 简单比较 -->
<view wx:if="{{count > 0}}">有数据</view>

<!-- 逻辑运算 -->
<view wx:if="{{isLogin && isVip}}">VIP用户</view>
```

**解决方案：**

```typescript
// 在 TS 中预处理数据，将复杂计算转换为简单布尔值
this.setData({
  // ❌ 不要在 WXML 中使用 indexOf
  // isSelected: selectedDates.indexOf(item.recordId) > -1

  // ✅ 在数据中直接提供 isSelected 字段
  list: rawList.map(item => ({
    ...item,
    isSelected: selectedDates.includes(item.recordId)
  }))
})
```

## Available Commands

```bash
# Lint and auto-fix (only command available)
npm run lint:fix

# Install dependencies (pnpm preferred based on lockfile)
pnpm install

# Build: Use WeChat Developer Tools
# - Import project with src/ as root
# - project.config.json at repo root
```

## NPM Dependencies

**Critical**: After `npm install`, run **Tools → Build npm** in WeChat Developer Tools to generate `miniprogram_npm/`. This is required for Vant and other packages.

Key dependencies:

- `@vant/weapp`: UI components
- `miniprogram-licia`: Utility library (available as `licia`)
- `dayjs`: Date handling
- `mp-html`: Rich HTML rendering

## Images & Assets

**Images are stored in SVN, not git.**

- SVN URL: `svn://39.106.86.127:28386/projects/xd/proj_src/shop/frontend/web/xd/`
- Local path: `src/images/` (gitignored)
- Excluded from upload via `project.config.json` packOptions
- Only `/images/tabbar/*` is included in uploads

Image URL pattern:

```
{{imageUrl}}/path/to/image.png?t={{Timestamp}}
```

## TypeScript Configuration

- Strict mode enabled
- `noImplicitAny: false` (allows implicit any)
- Paths: `@/*` mapped to `src/*`
- Types: `miniprogram-api-typings` for WX API

Global types in `typings/index.d.ts`:

- `IAppOption`: Global app instance interface
- `pageType`: 0 | 1 | 2 for user types
- `wx.ajax`: Extended request method

## ESLint & Formatting

- Config: `@antfu/eslint-config` (flat config in `eslint.config.js`)
- Prettier: 2-space tabs, no semis, single quotes, trailing commas
- WXML files parsed as HTML, WXSS as CSS
- Globals defined: `wx`, `App`, `Page`, `Component`, `getCurrentPages`, etc.

## Environment Configuration

Selected by App ID in `src/config.ts`:

- `wxf9ce8010f1ad24aa`: Dev/Staging (hbraas.com)
- `wx71ac9c27c3c3e3f4`: Production (hbsaas.com)

App reads `wx.getAccountInfoSync().miniProgram.appId` on launch to select config.

## Testing & Development

- No unit test framework configured
- Manual testing via WeChat Developer Tools
- `project.private.config.json` has hot reload enabled (`compileHotReLoad: true`)
- Predefined test pages in `project.private.config.json` condition list

## Common Gotchas

1. **NPM packages**: Must run "Build npm" in WeChat tools after install
2. **Images**: Will 404 if SVN images not checked out to `src/images/`
3. **Subpackages**: Patient pages are in `patient/` subpackage, not main package
4. **Skyline**: Enabled in rendererOptions, some components may behave differently
5. **Login flow**: App automatically calls `startLogin()` on launch; pages must wait via `app.zdWaitLogin()`

## 自定义导航栏规范

### 统一使用 navbar 组件

所有需要自定义导航的页面统一使用 `/components/navbar/index`。`/components/zd-navBar/navBar` 是历史遗留组件，新页面**不要使用**。

**JSON 配置：**

```json
{
  "navigationStyle": "custom",
  "usingComponents": {
    "navbar": "/components/navbar/index"
  }
}
```

**WXML 用法：**

```xml
<navbar fixed title="页面标题" custom-style="background:{{background}}">
  <van-icon name="arrow-left" slot="left" size="18px" color="#000" bind:tap="handleBack" />
</navbar>

<view class="page" style="padding-top:{{pageTop+20}}px;">
```

**TS 实现：**

```typescript
handleBack() {
  wx.navigateBack()
}
```

### 关键参数

| 属性           | 说明         | 常用值                      |
| -------------- | ------------ | --------------------------- |
| `fixed`        | 固定导航栏   | `fixed`                     |
| `title`        | 导航栏标题   | 字符串                      |
| `custom-style` | 自定义样式   | `background:{{background}}` |
| `leftArrow`    | 显示返回箭头 | Boolean                     |
| `slot="left"`  | 左侧插槽     | van-icon 返回按钮           |
| `bind:tap`     | 返回按钮点击 | `handleBack`                |

### pageTop 变量

`pageTop` 由 `utils/page.ts` wrapper 自动注入，表示导航栏高度。页面内容区使用 `padding-top:{{pageTop+20}}px;` 避开导航栏。**不要手动计算 navBarHeight**。

## 返回拦截与弹窗规范

### 使用自定义弹窗替代系统弹窗

**禁止使用** `wx.showModal` 进行操作确认，统一使用项目内的 popup 组件：

```json
{
  "usingComponents": {
    "popup": "/components/popup/index"
  }
}
```

```xml
<popup show="{{popupShow}}" type="{{popupType}}" params="{{popupParams}}" bind:ok="handlePopupOk" bind:cancel="handlePopupCancel" />
```

### 常用 popup 类型

| 类型      | 场景           | 标题               | 确认按钮 | 取消按钮 |
| --------- | -------------- | ------------------ | -------- | -------- |
| `popup15` | 删除确认       | "确认删除记录?"    | 确认删除 | 取消     |
| `popup16` | 未保存数据退出 | "您的记录还未保存" | 保存记录 | 退出     |
| `popup17` | 裁剪未保存退出 | "您有裁剪的照片"   | 退出     | 取消     |

### popup 数据定义

```typescript
data: {
  popupShow: false,
  popupType: 'popup16',
  popupParams: {
    close: false,
    position: 'center',
  } as any,
}
```

### 返回拦截模式

当页面有未保存数据时，使用自定义导航 + `bind:back` 拦截返回：

```typescript
handleBack() {
  if (this.hasUnsavedData()) {
    this.setData({ popupShow: true, popupType: 'popup16' })
  } else {
    wx.navigateBack()
  }
}

handlePopupOk() {
  this.setData({ popupShow: false })
  this.handleSave()
}

handlePopupCancel() {
  this.setData({ popupShow: false })
  wx.navigateBack()
}
```

**注意**：`navigationStyle: "custom"` 后系统返回手势无法拦截，只有 navBar 的返回按钮可被拦截。如需拦截系统返回手势，需要额外使用 `wx.enableAlertBeforeUnload`。

## wx.cropImage 规范

`wx.cropImage` 的 `src` 参数**只接受本地文件路径**，不支持网络 URL。裁剪网络图片时必须先用 `wx.getImageInfo` 下载到本地：

```typescript
handleCrop(e: any) {
  const index = e.currentTarget.dataset.index
  const photo = this.data.photos[index]

  wx.showLoading({ title: '加载中...' })
  wx.getImageInfo({
    src: photo.photoUrl,
    success: (imgRes) => {
      wx.hideLoading()
      wx.cropImage({
        src: imgRes.path,
        cropScale: '9:16',
        success: (cropRes) => {
          photos[index].croppedUrl = cropRes.tempFilePath
          this.setData({ photos })
        },
        fail: (err) => {
          if (err.errMsg?.includes('cancel')) return
          wx.showToast({ title: '裁剪取消', icon: 'none' })
        },
      })
    },
    fail: () => {
      wx.hideLoading()
      wx.showToast({ title: '图片加载失败', icon: 'none' })
    },
  })
}
```

## 子包组件引用规范

主包页面（`src/pages/`）**不能引用**子包组件（`src/patient/components/`）。如果主包和子包都需要使用某个组件，需要将组件复制到 `src/components/` 目录下。

示例：`image-merge` 组件在 `patient/components/` 和 `components/` 各有一份，分别供子包和主包页面使用。
