}
```

## Install

First thing's, install the module:

```
npm install postcss postcss-sort-media-queries --save-dev
```

## Usage

Check you project for existed PostCSS config: `postcss.config.js`
in the project root, `"postcss"` section in `package.json`
or `postcss` in bundle config.

If you already use PostCSS, add the plugin to plugins list:

```diff
module.exports = {
  plugins: [
+   require('postcss-sort-media-queries')({
+     sort: 'mobile-first', // default value
+   }),
    require('autoprefixer')
  ]
}
```

or with custom sort function
```diff
module.exports = {
  plugins: [
+   require('postcss-sort-media-queries')({
+     sort: function(a, b) {
+        // custom sorting function
+     }
+   }),
    require('autoprefixer')
  ]
}
```

If you do not use PostCSS, add it according to [official docs]
and set this plugin in settings.

## Options

> Sorting works based on [dutchenkoOleg/sort-css-media-queries](https://github.com/dutchenkoOleg/sort-css-media-queries) function.

### sort

This option support **string** or **function** values.

- `{string}` `'mobile-first'` - (default) mobile first sorting
- `{string}` `'desktop-first'` - desktop first sorting
- `{function}` your own sorting function

#### `'mobile-first'`

```js
postcss([
  sortMediaQueries({
    sort: 'mobile-first' // default
  })
]).process(css);
```

#### `'desktop-first'`

```js
postcss([
  sortMediaQueries({
    sort: 'desktop-first'
  })
]).process(css);
```

### Custom sort function
```js
postcss([
  sortMediaQueries({
    function(a, b) {
      return a.localeCompare(b);
    }
  })
]).process(css);
```

In this example, all your media queries will sort by A-Z order.

This sorting function is directly passed to Array#sort() method of an array of all your media queries.

### Sort configuration

By this configuration you can control sorting behaviour.

```js
postcss([
  sortMediaQueries({
    configuration: {
      unitlessMqAlwaysFirst: true, // or false
    }
  })
]).process(css);
```

Or alternatively create a `sort-css-mq.config.json` file in the root of your project. Or add property `sortCssMQ: {}` in your `package.json`.
