Getting Started

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a gruntfile.js 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-update-reference --save-dev

Once the plugin has been installed, it may be enabled inside your gruntfile.js with this line:

grunt.loadNpmTasks('grunt-update-reference');

Then, add and configure it to your Gruntfile.js:

grunt.initConfig({
    reference: {
        options:{
            //Define what files contain some reference.
            searchFileType: [ "*.html", "*.js", "*.css" ],
            //If has some file or path to ignore, path is base on "options.searchPathBase".
            searchIgnore:[ "ignore_me.html","ignore_me/**/*" ],
            //Task's log, "simple", "all" or "none"
            log:"simple"
        },
        dist: {
            options: {
                //The base path.
                searchPathBase: "./path_to",
                //Prevent watch instantly changes, which changed by this task.
                referenceIgnore:["*.html"]
            },
            //What kind of files that may needed to be update references.(path is not base on "options.searchPathBase")
            src: [ "path_to/**/*.{css,js,jpg,png,gif}" ]
        }
    }
  });

Run the grunt reference task:

If set log to "simple", the log will be like this:

$ grunt reference

Assets: foo.jpg
refresh foo.jpg's reference in bar.css
