Replaces references to resources on the Google CDN


Grunt task for replacing refs to resources on the Google CDN.

This module makes it easy to replace references to your bower resources in your app with links to the libraries on the Google CDN (and some other CDNs).

Install: npm install --save google-cdn

Install CDN data module: npm install --save google-cdn-data (see list of more data modules below)


  "name": "my-awesome-app",
  "dependencies": {
    "jquery": "~2.0.0"
var googlecdn = require('google-cdn');
var bowerConfig = loadJSON('bower.json');
var markup = '<script src="bower_components/jquery/jquery.js"></script>';
googlecdn(markup, bowerConfig, {cdn: require('google-cdn-data')}, function (errresult) {
  if (err) {
    throw err;
    '<script src="//"></script>');

Replaces references to libraries supported by the Google CDN in content. The library versions are inferred from the bowerJson.

options is an optional object with these keys:

  • componentsPath: defaults to bower_components, the path you specify in your script tags to the components directory.
  • cdn: defaults to require('google-cdn-data'). CDN you want to use. Object of the following format:
  jquery: {
    versions: ['2.0.3', '2.0.2', '2.0.1', '2.0.0'],
    urlfunction (version) {
      return '//my.own.cdn/libs/jquery/' + version + '/jquery.min.js';

You can turn on debugging by setting the DEBUG environment variable to google-cdn. E.g.

env DEBUG='google-cdn' grunt cdnify
