Grunt wrapper for node-match-media - plugin to extract styles matching certain media conditions, and create separate stylesheets with them

Getting Started

This plugin requires Grunt ~0.4.5

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-match-media --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-match-media');

The "match_media" task

Overview

In your project's Gruntfile, add a section named match_media to the data object passed into grunt.initConfig().

grunt.initConfig({
  match_media: {
    my_task: {
      options: {
        // Task-specific options go here.
      },
      your_target: {
        // Target-specific file lists and/or options go here.
      }
    }
  }
});

Options

options.width

Type: String Default value: '960px'

The viewport width for media queries to be evaluated against (in em or px).

options.height

Type: String Default value: '768px'

The viewport height for media queries to be evaluated against (in em or px).

options.px_em_ratio

Type: Integer Default value: 16

How many px to treat 1em as (by default 1em is treated as 16px)

options.orientation

Type: String Default value: undefined

What orientation queries to match, options are 'landscape', 'portrait', or 'both'

options.with_queries

Type: Boolean Default value: false

Preserves the media statements in the output CSS (default option is to write the styles without the query). This new option is useful for creating stylesheets for specific device ranges (but still have media queries within them).

options.always_match

Type: Array of Strings Default value: []

In case any options you require aren't covered by the task yet, you can pass a list of query types in to always match, whatever their value. Eg: ['min-device-pixel-ratio']

Usage Examples

Default Options

In this example, the styles from styles.css then other-styles.css are evaluated and any media queries which would apply in a 960px width browser are written into desktop-syles.css.

grunt.initConfig({
  match_media: {
    desktop: {
      files: {
        'desktop-styles.css': ['styles.css', 'other-styles.css']
      }
    }
  }
});

Custom Options

In this example, the styles from styles.css then other-styles.css are evaluated and any media queries which would apply in a 20em (or 20em * 16px = 320px) width browser are written into mobile-syles.css.

grunt.initConfig({
  match_media: {
    mobile: {
      options: {
        width: '20em',
        px_em_ratio: 16,
        orientation: 'portrait',
        always_match: [
          'min-device-pixel-ratio'
        ],
        with_queries: true
      },
      files: {
        'mobile-styles.css': ['styles.css', 'other-styles.css']
      }
    }
  }
});

Contributing

All of the functionality is now contained in the node-match-media project so any contributions may be more appropriate there.

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
