ember-preloader

You put your preloader in, you take your preloader out, You put your preloader in, and you shake it all about...

This addon allows you to render files directly in to the index.html on the initial build, then removes them from the DOM once your app has loaded. Useful for adding a preloading screen before the initial app is downloaded.

Install

ember install ember-preloader

Usage

The addon leverages the contentFor helper. In your app's ember-cli-build.js define your options hash, either using the existing contentFor hooks or your own:

var app = new EmberApp(defaults, {
  preloader: {
    head: 'preload.css',
    body: 'preload.html'
    'custom-hook': 'preload.js',
    'custom-hook2': 'preload2.js'
  }
});

If you've used custom hooks, add them to your index.html file:

{{content-for 'custom-hook'}}
{{content-for 'custom-hook2'}}

Finally, import the mixin into your application route:

import PreloaderMixin from 'ember-preloader/mixins/preloader';
export default Route.extend(PreloaderMixin, {});

Example

ember-cli-build.js:

var app = new EmberApp(defaults, {
  preloader: {
    head: 'preload.css',
    body: 'preload.html',
    'body-footer': 'preload.js',
  }
});

Output:

<style data-preloader>
  ... preload.css content ...
</style>

...

<div data-preloader>
  ... preload.html content ...
</div>

...

<script data-preloader>
  ... preload.js content ... 
</script>
