grunt-wordpress-rev

0.1.1 • Public • Published

Forked from grunt-rev, WIP to also have it update a file with the new filenames.

grunt-wordpress-rev

Static file asset revisioning through content hashing, updating a given file with the new filenames

Getting Started

If you haven't used grunt before, be sure to check out the Getting Started guide.

From the same directory as your project's Gruntfile and package.json, install this plugin with the following command:

npm install grunt-wordpress-rev --save-dev

Once that's done, add this line to your project's Gruntfile:

grunt.loadNpmTasks('grunt-rev');

Another way is to use the matchdep plugin:

npm install matchdep --save-dev

Once that's done, add this line to your project's Gruntfile:

require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks);

If the plugin has been installed correctly, running grunt --help at the command line should list the newly-installed plugin's task or tasks. In addition, the plugin should be listed in package.json as a devDependency, which ensures that it will be installed whenever the npm install command is run.

The "wpRev" task

Use the wpRev task together with yeoman/grunt-usemin for cache busting of static files in your app. This allows them to be cached forever by the browser.

Overview

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

grunt.initConfig({
  wpRev: {
    options: {
      encoding: 'utf8',
      algorithm: 'md5',
      length: 8,
      file: 'file/to/update.php'
    },
    assets: {
      files: [{
        src: [
          'scripts/{,*/}*.js',
          'styles/{,*/}*.css'
          'img/**/*.{jpg,jpeg,gif,png}',
          'fonts/**/*.{eot,svg,ttf,woff}'
        ]
      }]
    }
  },
})

Options

options.encoding

Type: String Default value: 'utf8'

The encoding of the file contents.

options.algorithm

Type: String Default value: 'md5'

algorithm 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.

options.length

Type: Number Default value: 8

The number of characters of the file content hash to prefix the file name with.

options.file

Type: String

options.revert

Type: Bool Default value: false

Usage Examples

Basic Asset Revving

This will rename app.js and app.css with an 8 character long hash prefix. For example js/9becff3a.app.js and css/ae35dd05.app.css. The hash value depends on the file contents. The file where these are called upon is the core theme file functions.php.

grunt.initConfig({
  wpRev: {
    options: {
      file: 'functions.php'
    },
    files: {
      src: ['scripts/app.js', 'css/app.css']
    }
  }
})

Custom Options

Change the algorithm or length to style the generated asset file names. Note that the usemin companion task requires at least one anycase hexadecimal character to prefix the file name.

grunt.initConfig({
  rev: {
    options: {
      algorithm: 'sha1',
      length: 4,
      file: 'functions.php'
    },
    files: {
      src: ['**/*.{js,css,png,jpg}']
    }
  }
})

Reverting filenames

Setting the revert option to true will generate the new files reverting the hash with the file name. Use this option if you want to generate files like main.min.50a592.css instead of 50a592.main.min.css

grunt.initConfig({
  rev: {
    options: {
      revert: true,
      file: 'header.php'
    },
    files: {
      src: [
        'js/**/*.js',
        'css/**/*.css'
        ]
    }
  },
})
