#broccoli-asset-rev

Broccoli plugin to add fingerprint checksums to your files and update the source to reflect the new filenames.

Turns

<script src="assets/appname.js">
background: url('/images/foo.png');

Into

<script src="https://subdomain.cloudfront.net/assets/appname-342b0f87ea609e6d349c7925d86bd597.js">
background: url('https://subdomain.cloudfront.net/images/foo-735d6c098496507e26bb40ecc8c1394d.png');

Installation

npm install broccoli-asset-rev --save-dev

Usage

var assetRev = require('broccoli-asset-rev');

var assetTree = assetRev(tree, {
  extensions: ['js', 'css', 'png', 'jpg', 'gif'],
  exclude: ['fonts/169929'],
  replaceExtensions: ['html', 'js', 'css'],
  prepend: 'https://subdomain.cloudfront.net/'
});

Options

• extensions - Default: ['js', 'css', 'png', 'jpg', 'gif', 'map'] - The file types to add md5 checksums.
• exclude - Default: [] - An array of strings. If a filename contains any item in the exclude array, it will not be fingerprinted.
• replaceExtensions - Default: ['html', 'css', 'js'] - The file types to replace source code with new checksum file names.
• prepend - Default: '' - A string to prepend to all of the assets. Useful for CDN urls like https://subdomain.cloudfront.net/
• generateRailsManifest - Default: none - If true, will generate a manifest.json to be used by Sprockets for the Rails Asset Pipeline. The manifest will be fingerprinted by default but this can be avoided by adding 'manifest.json' to the exclude list.
• customHash - Default: none - If set, overrides the md5 checksum calculation with the result of calling customHash(buffer). If it is not a function, customHash is used as the hash value.
• generateAssetMap - Default: false. If true, will generate a assetMap.json file in a assets directory on the output tree. This file contains a mapping of the original asset name to the fingerprinted asset, like the following:

{
	assets: {
		css/file1.css: css/file1-sdaa7d6a87d6ada78ds.css,
		images/image1.png: images/image1-sdaa7d6a87d6ada78ds.css,
	}
}

Ember CLI addon usage

var app = new EmberApp({
  fingerprint: {
    exclude: ['fonts/169929'],
    prepend: 'https://sudomain.cloudfront.net/'
  }
});

Ember CLI addon options

• exclude - Default: [] - An array of strings. If a filename contains any item in the exclude array, it will not be fingerprinted.
• extensions - Default: ['js', 'css', 'png', 'jpg', 'gif', 'map'] - The file types to add md5 checksums.
• prepend - Default: '' - A string to prepend to all of the assets. Useful for CDN urls like https://subdomain.cloudfront.net/
• replaceExtensions - Default: ['html', 'css', 'js'] - The file types to replace source code with new checksum file names.
