    Build Status Dependency Status devDependency Status npm Version npm Downloads

    A grunt task which takes a html file, finds all the css, js links and images, and outputs a version with all the css, js and images (Base64) written inline.

    This is a fork of original grunt-html-smoosher by Ben Breedlove with fixes and new features.

    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-assets-inline --save-dev

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

    grunt.loadNpmTasks('grunt-assets-inline');

    The "assets_inline" task

    Overview

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

    grunt.initConfig({
      assets_inline: {
        options: {
          jsTags: { // optional
            start: '<script type="text/javascript">', // default: <script>
            end: '</script>'                          // default: </script>
          },
        },
        all: {
          files: {
            'dest-index.html': 'source-index.html',
          },
        },
      },
    });

    Options

    Script Minification

    Defaults to false.

    Minify scripts with UglifyJS.

     
    grunt.initConfig({
      assets_inline: {
        all: {
          options: {
            minify: true
          },
          files: {
            'dest-index.html': 'source-index.html',
          },
        },
      },
    });

    Path config

    Defaults to "".

    When you have absolute paths for your external assets, it helps to add the local address of your asset files; relative to uncompiled HTML file.

    grunt.initConfig({
      assets_inline: {
        all: {
          options: {
            jsDir: "../",
            cssDir: "/project/styles/",
            assetsDir: "/project/"
          },
          files: {
            'dest-index.html': 'source-index.html',
          },
        },
      },
    });

    Example

    If the local cwd for your uncompiled file is /project/html then the above settings would resolve:

    <script src="/assets/js/script.js"> will use a local file at /project/js/script.js

    <link href="/assets/css/styles.css"> will use a local file at /project/styles/assets/css/styles.css

    <img src="/assets/svg/header.svg"> will use a local file at /project/assets/svg/header.svg

    Inline Images

    Defaults to false.

    If you want to smoosh img sources to Base64 in HTML, you can set inlineImg to true.

    grunt.initConfig({
      assets_inline: {
        all: {
          options: {
            inlineImg: true
          },
          files: {
            'dest-index.html': 'source-index.html',
          },
        },
      },
    });

    Inline SVGs

    Defaults to true.

    If you want to smoosh SVGs in img tags in HTML, you can set inlineSvg to true.

    grunt.initConfig({
      assets_inline: {
        all: {
          options: {
            inlineSvg: true
          },
          files: {
            'dest-index.html': 'source-index.html',
          },
        },
      },
    });

    <img src="src/to/header.svg"> will turn into <img src="data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' width='2175....

    Inline SVGs with Base64

    Defaults to false.

    grunt.initConfig({
      assets_inline: {
        all: {
          options: {
            inlineSvg: true,
            inlineSvgBase64: true
          },
          files: {
            'dest-index.html': 'source-index.html',
          },
        },
      },
    });

    SVG images are inlined directly into HTML by default. To have more compatibility with older browsers, you can also Base64 SVGs:

    <img src="src/to/header.svg"> will turn into <img src="data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0....

    Please note that Base64 generated files are always slightly bigger than the original files.

    Additional Assets URL Prefix

    If you have assets in CSS or JS (for example images, fonts, SVGs), smooshing CSS or JS into HTMLs may break relative URLs, so you may have to replace the original URLs to absolute URLs.

    This option only searchs for URLs begin with ../.

    grunt.initConfig({
      assets_inline: {
        all: {
          options: {
            assetsUrlPrefix: '<%= config.base %>/assets/'
          },
          files: {
            'dest-index.html': 'source-index.html',
          },
        },
      },
    });

    includeTag

    Defaults to "".

    grunt.initConfig({
      assets_inline: {
        all: {
          options: {
            includeTag: "?assets-inline"
          },
          files: {
            'dest-index.html': 'source-index.html',
          },
        },
      },
    });

    By default all CSS and JS files are smooshed in HTML, If you only need specific files to be smooshed, you should define includeTag.

    For example the above configuration only smoosh filenames with ?assets-inline queries:

    <link href="/assets/css/styles.css?assets-inline">

    cssTags

    Defaults to

    {
      start: "<style>",
      end: "</style>"
    }

    jsTags

    Defaults to

    {
      start: "<script>",
      end: "</script>"
    }

    deleteOriginals

    Defaults to

    {
      deleteOriginals: false
    }

    You can delete smooshed files after the main task. Please note that once a file is smooshed into the HTML, it will marked as pending delete, no matter if it is included elsewhere without smooshing.

    verbose

    Defaults to

    {
      verbose: false
    }
