This extension adds support for [clean-css](https://github.com/jakubpawlowicz/clean-css) to [Laravel Mix](https://github.com/JeffreyWay/laravel-mix) by using the [clean-css-loader](https://github.com/retyui/clean-css-loader).

## Installation

```
npm i -D laravel-mix-clean-css
```

## Usage

Require the extension inside your ``webpack.mix.js`` and add clean-css configurations like this:

```javascript
const mix = require('laravel-mix');

require('laravel-mix-clean-css');

mix
  .sass('src/app.scss', 'dist')
  .sass('src/app.sass', 'dist')
  .less('src/app.less', 'dist')
  .stylus('src/app.styl', 'dist')

  // Run clean-css on all stylesheets
  .cleanCss({
    level: 2,
    format: mix.inProduction() ? false : 'beautify' // Beautify only in dev mode
  })

  // Run clean-css only on one specific stylesheet
  .cleanCss({
    // ...
  }, 'src/app.scss')

  // Run clean-css only on multiple specific stylesheets
  .cleanCss({
    // ...
  }, [
    'src/app.scss',
    'src/app.sass',
  ])
```

For more information about clean-css configurations please refer to their [documentation](https://github.com/jakubpawlowicz/clean-css/blob/master/README.md).
