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-generate-hash --save-dev

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

grunt.loadNpmTasks('grunt-generate-hash');

The "generate_hash" task

Overview

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

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

Options

algorithm

Type: string Default: 'md5'

lgorithm is dependent on the available algorithms supported by the version of OpenSSL on the platform. Examples are 'sha1', 'md5', 'sha256', 'sha512', etc. On recent releases, openssl list-message-digest-algorithms will display the available digest algorithms.

hashlen

Type: number Default: 8

Number of characters of the file hash to prefix the file name with.

Usage Examples

Default Options

In this example, the default options are used to do something with whatever. So if the testing file has the content Testing and the 123 file had the content 1 2 3, the generated result would be Testing, 1 2 3.

grunt.initConfig({
  generate_hash: {
    options: {},
    files: [{
        expand: true,
        cwd: 'src',
        src: ['**/*.{png,jpg,jpeg,gif,js,css}'],
        dest: 'static'
    }]
  },
});
