title: Aurelia CLI and IE9
body: <p>I'm tying to make Aurelia-CLI support IE9.
  As said <a href="https://github.com/aurelia/skeleton-navigation/issues/236#issuecomment-220570291" rel="nofollow">here</a> we need "raf" to polyfill the lack of <code>requestAnimationFrame</code> in IE9.
  They say to load it before the <code>aurelia-bootstrapper</code> as follow:</p>
  
  <pre><code>&lt;script&gt;
    System.import('raf')
    .then(function(raf){
      raf.polyfill();
      return System.import('aurelia-bootstrapper');
    });     
  &lt;/script&gt;
  </code></pre>
  
  <p>But with the <code>Aurelia-CLI</code> I don't have such script in the <code>index.html</code>, instead there is:</p>
  
  <pre><code>&lt;body aurelia-app="main"&gt;
    &lt;script src="scripts/vendor-bundle.js" data-main="aurelia-bootstrapper"&gt;&lt;/script&gt;
  &lt;/body&gt;
  </code></pre>
  
  <p>I tryied to install it with <code>npm i raf performance-now</code> and configured in <code>aurelia_project/aurelia.json</code> but it's still not working.</p>
  
  <p>What I'm missing?</p>
