Angular 2 bootstrap process
<p>I want to make an AJAX request before calling the bootstrap method in Angular 2 to bootstrap the application on page load. </p>

<p>Are there any hooks I can listen for to do this using Angular? I know I could wrap it in a vanilla javascript ajax request but I thought there maybe a standard way to do this with Angular 2. I need to get a configuration file from a server before I spin up the Angular 2 App.  </p>
