Example

exports.config =
  # ... 
  plugins:
    fingerprint:
      manifest: './assets.json'
      srcBasePath: './exemple/'
      destBasePath: './out/'
      hashLength: 8
      autoClearOldFiles: false
      targets: '*'
      environments: ['production']
      alwaysRun: false
      autoReplaceAndHash: false
      publicRootPath: './public'
      manifestGenerationForce: false
      foldersToFingerprint: false
      assetsToFingerprint: false

The Manifest

{
  "css/master.css": "css/master-364b42a1.css",
  "js/master.js": "js/master-cb60c02b.js",
  "img/troll.png": "img/troll-5f2d5cbe.png",
  "fonts/font.eot": "fonts/font-45d860a3.eot",
  "fonts/font.woff": "fonts/font-6ced13b9.woff",
  "fonts/font.ttf": "fonts/font-82c653e7.ttf",
  "fonts/font.svg": "fonts/font-52343d4f.svg"
}

Fingerprint All

To get this kind of result in your manifest you need to :

• Set autoReplaceAndHash to true
• Or set foldersToFingerprint pointing to one folder ./img, or many ['./img', './svg']
• Or set assetsToFingerprint pointing to files ['./img/troll.png']

Cleaning Manifest

Use srcBasePath and destBasePath to remove some part of path files in the manifest.

Options

assetsPrefix

Sometimes you may want to add a prefix to assets when replacing their path in your compiled css/js.

Say you have a CSS file containing:

.logo {
  background-image: url('logo.svg');
}

once replaced, the content would look like:

.logo {
  background-image: url('logo-f98d59ab3.svg');
}

if you were to set assetsPrefix: '/custom/' the result would be:

.logo {
  background-image: url('/custom/logo-f98d59ab3.svg');
}

Note: This could also be leveraged to prepend a CDN url for instance.
