How to handle version of files in angular 2
<p>In current angular app 1.x, I use a custom module and file loader, which allow me adding a suffix(v=x.y) to file url. Browser will base on that suffix to load file from cache or take it from server. Such as:</p>

<pre><code>'app/user/user.services.js?v=1.2',
'app/order/order.services.js?v=1.3',
</code></pre>

<p>Version numbers(1.2, 1.3...) is set dynamically in each user session by my loader, version number for each file can be different.</p>

<p>On angular 2, with SystemJs, <strong>how can I define version number for files imported by SystemJs</strong> used in my app.</p>

<p>Suggesting me <strong>some other loaders</strong> to solve this case is highly appreciated!</p>
