Need I use NodeJS to show an OpenLayers 3 map inside a page?
<p>I am absolutly new in <strong>OpenLayers 3</strong> and I have started studying this tutorial: <a href="http://openlayers.org/workshop/index.html" rel="nofollow noreferrer">http://openlayers.org/workshop/index.html</a></p>

<p>As you can see in the previous link is specified that:</p>

<blockquote>
  <p>In addition, you'll need Node installed to run a development server
  for the OpenLayers library.</p>
</blockquote>

<p>So it means that for evry application that show a map using Open Layers 3 I need to install also <strong>Node JS</strong>? Why to show a map I need Node?</p>

<p>Am I missing something?</p>
