Pace.js load progress bar for Ember apps, incl. initial scripts lazy loading

Downloads Code Climate Ember Observer Score David Dependencies

Demo ➜

Installation

Using latest Ember-cli, run the command:

ember install ember-cli-pace

or for older versions:

npm install ember-cli-pace && ember g pace

Flash-like initial script loading

Due to application scripts loading may take some time (especially, using mobile networks or ADSL), Ember-cli-pace can load them asynchronously displaying correctly computed progress bar. To enable that feature, just change src attribute to pace-src in your app.html.

<script pace-src="assets/vendor.js"></script>
<script pace-src="assets/app.js"></script>

Therefore, the scripts will be loaded via AJAX, which allows to compute loaded vs total bytes ratio. If your scripts are located on separate host, please note CORS policy.

Configuration

All options, excluding color and theme related to the addon, are documented on http://github.hubspot.com/pace/.

  pace: {

    theme: 'minimal',
    color: 'blue',
