title: Angular universal alternative to queryselector
body: <p>All the plugins which are currently supporting angular 2.0 don't seem to support Angular Universal. It shows errors due to the direct <code>DOM</code> access. I want to alter the <code>DOM</code> access code in the angular 2 way. Can anyone suggest the angular 2 way for window, document,<code>queryselector()</code>, <code>querySelectorAll()</code>, <code>document.getElementsByTagname()</code>, <code>getElementsByClassName()</code>, etc.</p>
