> `Let's make rpx great again!` LOL

`postcss-pxtransform` 的反向版本，用来把小程序的 `rpx` 单位，转化为 `px`，`rem`，`vw` 这些单位。

## 何时使用？

有些项目，是以小程序为主体进行设计的，一开始可能只要求做一个小程序，但是后续逐渐产生了`app`和`h5`这些其他平台的需求。

此时由于开发者们样式里，全部用了`rpx`这类的单位，`h5`压根不认识这个单位，而此时全局更改`rpx`到其他单位(`px`,`rem`)的成本也比较高，此时你就需要这个插件来进行反向转化！

## 如何使用

### Postcss8

```js
// postcss.config.js
module.exports = {
  plugins: [
    require('postcss-rpx-transform')(),
  ],
}
```

### Postcss7

```js
// postcss.config.js
module.exports = {
  plugins: [
    require('postcss-rpx-transform/postcss7')(),
  ],
}
```

## 配置项

```ts
export interface UserDefinedOptions {
  // 反向转化的基准单位，默认是32，即 32rpx = 16px = 1rem = 32/750 * 100vw
  rootValue?: number | ((input: Input) => number)
  // 四舍五入后保留小数
  unitPrecision?: number
  // 选择器黑名单，会直接跳过黑名单内的处理
  selectorBlackList?: (string | RegExp)[]
  // 处理的 css 属性列表
  propList?: string[]
  // 处理策略为直接覆盖原先 replace，还是添加覆盖 appned
  replace?: boolean
  // 是否处理媒体查询
  mediaQuery?: boolean
  // 最小值以下不处理
  minValue?: number
  // 排除指定路径不处理
  exclude?: string | RegExp | ((filePath: string) => boolean)
  // 转化的目标单位，支持 rpx2px,rpx2rem,rpx2vw
  transformUnit?: 'px' | 'rem' | 'vw'
}
// 默认值
export const defaultOptions: Required<UserDefinedOptions> = {
  // 32rpx = 16px = 1rem = 32/750 * 100vw
  rootValue: 32,
  unitPrecision: 5,
  selectorBlackList: [],
  propList: ['*'],
  replace: true,
  mediaQuery: false,
  minValue: 0,
  exclude: /node_modules/i,
  transformUnit: 'px'
}
```
