    grunt-css-url-embed

      

    Embed URLs as base64 data URIs inside your stylesheets

    There are lots of base64 embedding Grunt plugins out there, but pretty much all of them are already outdated and/or abandoned. This plugin aims to change that.

    Getting Started

    This plugin requires Grunt ~0.4.0 and Python 2.7, since it depends on node-gyp.

    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-css-url-embed --save-dev

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

    grunt.loadNpmTasks('grunt-css-url-embed');

    cssUrlEmbed task

    Task targets, files and options may be specified according to the grunt Configuring tasks guide.

    Both image and font URLs are supported. Remote (http, https) URLs are supported as well.

    Options

    baseDir

    Type: String

    Default: . or the directory of Gruntfile.js

    The base directory for URLs. Can be absolute or relative to the directory of your Gruntfile.js.

    failOnMissingUrl

    Type: Boolean

    Default: true

    Will the script terminate if the file referenced by the URL is missing or the request to get it failed?

    When set to false a warning will be produced for each missing file or failed request.

    skipUrlsLargerThan

    Type: String

    Default: No restrictions

    Skip URLs that are larger than the specified value.

    For example: '5 MB', '30 KB', '300 B'.

    inclusive

    Type: Boolean

    Default: false

    Specifies the mode of embedding.

    • true (inclusive) means that you have to manually mark each URL that needs to be embedded using the /* embed */ comment.
    • false (exclusive) means that every URL is embedded, except those that are marked with /* noembed */ comment.

    useMimeTypeSniffing

    Type: Boolean

    Default: true

    Should we try to use the mmmagic MIME-type sniffing library or should we always determine MIME-type only from the extension of the URL?

    When set to false the extension checking is always used. When set to true it will first try use the mmmagic library. However, in case the library failed to install it will fallback to extension checking.

    Usage Examples

    Map input and output files directly

    cssUrlEmbed: {
      encodeDirectly: {
        files: {
          'path/to/output.css': ['path/to/input.css']
        }
      }
    }

    Specify base directory if needed

    cssUrlEmbed: {
      encodeWithBaseDir: {
        options: {
          baseDir: './app'
        },
        files: {
          'path/to/output.css': ['path/to/input.css']
        }
      }
    }

    Process all CSS files in target directory

    cssUrlEmbed: {
      encode: {
        expand: true,
        cwd: 'target/css',
        src: [ '**/*.css' ],
        dest: 'target/css'
      }
    }

    Exclude URLs by size

    cssUrlEmbed: {
      encode: {
        options: {
          skipUrlsLargerThan: '5 MB'
        },
      
        expand: true,
        cwd: 'target/css',
        src: [ '**/*.css' ],
        dest: 'target/css'
      }
    }

    Disable MIME-type sniffing in favor of extension checking

    cssUrlEmbed: {
      encode: {
        options: {
          useMimeTypeSniffing: false
        },
      
        expand: true,
        cwd: 'target/css',
        src: [ '**/*.css' ],
        dest: 'target/css'
      }
    }

    Excluding URLs manually (when inclusive: false)

    .exclude-me {
      background-image: url('exclude_me.png'); /* noembed */
    }

    Including URLs manually (when inclusive: true)

    .include-me {
      background-image: url('include_me.png'); /* embed */
    }

    When URLs are in the middle of CSS property

    .include-me1 {
      background: transparent url('include_me.png') /* embed */ center center no-repeat;
    }
     
    .include-me2 {
      background-image: -webkit-image-set(url('include_me1.png') /* embed */ 1x, url('include_me2.png') /* embed */ 2x);
    }
