grunt-keaton

Bust your assets via a hash change in a dedicated one liner version file.

For example, load the hash from a version.txt and use it in your generated HTML in your assets paths:

  <link rel="stylesheet" href="//assets.domain.tld/a253/css/base.css" />
  <script src="//assets.domain.tld/a253/js/core.js"></script>
  …

In the Apache conf for your assets subdomain:

  RewriteRule ^/[^/]+/(.*)$ /$1 [PT,L]

Getting Started

This plugin requires Grunt ~0.4.5

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-keaton --save-dev

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

grunt.loadNpmTasks('grunt-keaton');

The "keaton" task

Overview

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

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

Options

options.algorithm

Type: String Default value: 'sha1'

Hash algorithm such as 'sha1', 'md5', 'sha256', etc. Note that it must be available on your platform.

options.length

Type: Integer Default value: 4

The length of the generated hash.

Usage Examples

Default Options

Using sha1 algorithm to generate a four character hash in ./version.txt

grunt.initConfig({
  keaton: {
    options: {},
    files: {
      src: ['version.txt']
    },
  },
});

Custom Options

Using md5 algorithm to generate a six character hash in ./static/version.txt

grunt.initConfig({
  keaton: {
    options: {
      algorithm: 'md5',
      length: 6,
    },
    files: {
      src: ['static/version.txt']
    },
  },
});

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.
