<h3 id="summary-problem-motivation">Motivation</h3>
<p><a href="https://www.drupal.org/project/experience_builder">Experience builder</a> (short XB) is currently in development and the 1.0 release is scheduled for October, at Drupalcon Vienna.</p>
<p>We want to integrate with it nicely and enable the following use-cases:</p>
<ul>
<li>A) Expose (global, custom-elements) Vue components of a nuxt frontend to XB, such that they show up as placeable components</li>
<li>B) Render components within XB editor with Nuxt, to have a proper preview during editing</li>
<li>C) Render XB pages with Lupus Decoupled Drupal, with support for blocks, Vue components as well is in-code (P)React components</li>
<li>2nd prio: Enable using Vue in in-browser code-components and enable server-rendering them</li>
</ul>
