### native-message api

<!-- 选择文件 -->

postMessage({ api: 'chooseFile', content: {
type: 'img' | 'video' | 'file' | 'midi' | 'mp3' | 'xml',
max: 1
}}, (res) => {

  <!-- fileUrl。 如果是视频 firstFrameImg -->

})

<!-- 进入直播间 -->

postMessage({ api: 'joinLiveRoom', content: {
roomId: 'xxx',
teacherId: 'xxx'
})

<!-- 进入群聊天 -->

postMessage({
api: 'joinChatGroup',
content: {
type: 'multi', // single 单人 multi 多人
id: item.id,
role: 'STUDENT' || 'TEACHER'
}
})

<!-- 拉起支付 -->

postMessage({
api: 'paymentOrder',

orderNo: this.orderInfo.orderNo,
payInfo: `alipays://platformapi/startapp?saId=10000007&qrcode=${res.data.pay_info}`
}
})

<!-- 原生导航是否显示 -->

postMessage({api:'setBarStatus',content:{status:1}});

<!-- 原生导航返回样式 -->

postMessage({api:'backIconChange',content:{iconStyle:'black'}});

<!-- 获取原生导航高度 -->

postMessage({ api: 'getNavHeight' })

### 获取某个目录下面的图片对象

export const getAssetsHomeFile = (fileName: string) => {
const path = `../images/${fileName}`
const modules = import.meta.globEager('../images/\*')
return modules[path].default
}

- 需要带上图片后辍
  getAssetsHomeFile('xxx.png')

### Rem Unit (default)

Vant uses `px` unit by default,You can use tools such as `postcss-pxtorem` to transform `px` unit to `rem` unit.

- [postcss-pxtorem](https://github.com/cuth/postcss-pxtorem)
- [lib-flexible](https://github.com/amfe/lib-flexible)

#### PostCSS Config

PostCSS config example:

```js
// .postcssrc.js
module.exports = {
  plugins: {
    'postcss-pxtorem': {
      rootValue: 37.5,
      propList: ['*']
    }
  }
}
```

### Viewport Units

you can use tools such as [postcss--px-to-viewport](https://github.com/evrone/postcss-px-to-viewport) to transform `px` unit to viewport units (vw, vh, vmin, vmax).

#### PostCSS Config

PostCSS config example:

```js
// .postcssrc.js
module.exports = {
  plugins: {
    'postcss-px-to-viewport': {
      viewportWidth: 375
    }
  }
}
```

### Custom rootValue

If the size of the design draft is 750 or other sizes, you can adjust the `rootValue` to:

```js
// .postcssrc.js
module.exports = {
  plugins: {
    // postcss-pxtorem version >= 5.0.0
    'postcss-pxtorem': {
      rootValue({ file }) {
        return file.indexOf('vant') !== -1 ? 37.5 : 75
      },
      propList: ['*']
    }
  }
}
```

## Recommended IDE Setup

- [VSCode](https://code.visualstudio.com/) + [Volar](https://marketplace.visualstudio.com/items?itemName=johnsoncodehk.volar)

## Type Support For `.vue` Imports in TS

Since TypeScript cannot handle type information for `.vue` imports, they are shimmed to be a generic Vue component type by default. In most cases this is fine if you don't really care about component prop types outside of templates. However, if you wish to get actual prop types in `.vue` imports (for example to get props validation when using manual `h(...)` calls), you can enable Volar's `.vue` type support plugin by running `Volar: Switch TS Plugin on/off` from VSCode command palette.
