grunt-asset-hash v0.1.9

grunt-asset-hash

Create a folder of asset files that include hashes

Getting Started

This plugin requires Grunt ~1.0.1

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-asset-hash --save-dev

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

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

The "asset_hash" task

Overview

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

grunt.initConfig({
  asset_hash: {
    options: {
      preserveSourceMaps: false,  // Set to true when assets should share the same location as their source map.
      assetMap: 'assetmap.json',  // A mapping file between assets and their hashed locations. Set to `false` to skip generating.
      hashLength: 32,             // Number of hex characters in the hash folder. (0 means no hashing is done).
      algorithm: 'md5',           // Crypto algorithm used to hash the contents.
      srcBasePath: '',            // The directory prefix to be stripped from the asset map src paths.
      destBasePath: '',           // The directory prefix to be stripped from the asset map dest paths.
      hashType: 'folder',         // Defaults to `/$HASH/filename.ext`, but `'file'` will output `filename.$HASH.ext`.
      references: []              // Files to replace references in (eg. a CSS file where `image.png` should become `image.$HASH.png`)
    },
    your_target: {
      files: [
        { src:  ['assets/**/*'],  // A collection of assets to be hashed.
          dest: 'hashed'          // A folder to contained the hashed assets. Cannot be a file.
        }
      ]
    },
  },
});

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.
