Discourse commenting for more complex, dynamic website

[philooo (phil)]

I found a WP plugin for Discourse, claiming that they can define the ‘Category’
→ GitHub - discourse/wp-discourse: WordPress plugin that lets you use Discourse as the community engine for a WordPress blog · GitHub

I am looking into the code but I can’t seem to find how they do it. If someone is familiar with this plugin I’d love to know if this is working or just wishful thinking ;(

What I wish for:

<script type="text/javascript">
  var discourseUrl = "http://forums.domain.tld/",
  		discourseUserName = 'Username',
  		discourseEmbedCategory = 'Category/Sub-category',
      discourseEmbedUrl = 'http://forums.domain.tld/article-url.html';

  (function() {
    var d = document.createElement('script'); d.type = 'text/javascript'; d.async = true;
      d.src = discourseUrl + 'javascripts/embed.js';
    (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(d);
  })();
</script>
