Fingerprinting

ember-cli comes with fingerprinting support built-in. In most production scenarios you will need to provide a prepend-property to your app’s fingerprint-property (to reference your CDN served assets correctly).

// ember-cli-build.js
var app = new EmberApp({
  fingerprint: {
    prepend: 'https://subdomain.cloudfront.net/'
  }
});

ember-cli will only create a production like build for the production-environment by default. If you want to support multiple ‘production-like’ environments you need to configure minification for these environments manually. You can do someting like this:

// ember-cli-build.js
var env = EmberApp.env();
var isProductionLikeBuild = ['production', 'staging'].indexOf(env) > -1;

var app = new EmberApp({
  fingerprint: {
    enabled: isProductionLikeBuild,
    prepend: 'https://subdomain.cloudfront.net/'
  },
  sourcemaps: {
    enabled: !isProductionLikeBuild,
  },
  minifyCSS: { enabled: isProductionLikeBuild },
  minifyJS: { enabled: isProductionLikeBuild },

  tests: process.env.EMBER_CLI_TEST_COMMAND || !isProductionLikeBuild,
  hinting: process.env.EMBER_CLI_TEST_COMMAND || !isProductionLikeBuild,

  vendorFiles: {
    'handlebars.js': {
      staging:  'bower_components/handlebars/handlebars.runtime.js'
    },
    'ember.js': {
      staging:  'bower_components/ember/ember.prod.js'
    }
  }
});
