grunt-concat-css

Concat CSS with @import statements at top and relative url preserved.

Getting Started

This plugin requires Grunt ~0.4.1

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-concat-css --save-dev

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

grunt.loadNpmTasks('grunt-concat-css');

The "concat_css" task

Overview

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

grunt.initConfig({
  concat_css: {
    options: {
      // Task-specific options go here.
    },
    all: {
      src: ["/**/*.css"],
      dest: "styles.css"
    },
  },
})

Usage Examples

Default Options

By default, all css are concatenated. The only things that happens is that every @import statement are placed at the begininning of the resulting file (as @import statement).

grunt.initConfig({
  concat_css: {
    options: {},
    files: {
      'dest/compiled.css': ['src/styles/componentA.css', 'src/styles/componentB.css'],
    },
  },
})

Rebase URLs

By specifying assetBaseUrl and baseDir, all the assets will be rebased relative to this project rebase URL.

grunt.initConfig({
  concat_css: {
    options: {
      assetBaseUrl: 'static/assets',
      baseDir: 'src/(styles|assets)'
    },
    files: {
      'static/styles.css': ['src/styles/**/*.css', 'src/assets/**/*.css']
    }
  }
})

Contributing

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.
