grunt-assets-hash

Rename assets files with hash for better caching and add to JSON file

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-hash --save-dev

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

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

NOTE

This plugin is based in grunt-asset-version-json by Andy Ford

Usage Example

assets_hash: {
  assets: {
    options: {
      algorithm: 'sha1',
      jsonFile: 'assets/versions.json',
      clear: true
    },
    src: 'public/assets/css/main.css'
  }
},

This example task will rename public/assets/css/main.css to public/assets/css/main.{sha1hash}.css and update assets reference in assets/versions.json which would look something like { "public/assets/css/main.css": "public/assets/css/main.SOMEHASH.css" };

Options

rename

Type: Boolean
Default: false

It will rename the src target instead of copy.

suffix

Type: Boolean
Default: false

Define the file name format as suffixed or prefixed.

true: {filename}.{hash}.{ext}  
false: {hash}.{filename}.{ext}

encoding

Type: String
Default: 'utf8'

The file encoding.

algorithm

Type: String
Default: '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.

length

Type: Number
Default: 8

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

jsonFile

Type: String
Default: assets-hash.json

The JSON file that will contain all reference to files and hashs. If that file doesn't exists, will be created.

clear

Type: Boolean
Default: false

If true, will delete old hashed file.

fullPath

Type: Boolean
Default: true

If true, the paths will be present in JSON file.

removeFromPath

Type: String
Default: ``

If this string is not empty, will be removed from path.
Example: if you hash public/assets/main.90ea3212.css and removeFromPath is set to public/ your JSON will contain only assets/main.90ea3212.css
