      With the Collaboration Extension it's possible for several users to work on a document at the same time. To make this possible, client-side and server-side code is required. This example shows this using a <a href="https://glitch.com/edit/#!/tiptap-sockets" target="_blank">socket server</a>. Try it out below:
    </div>
    <template v-if="editor && !loading">
      <div class="count">
        {{ count }} {{ count === 1 ? 'user' : 'users' }} connected
      </div>
      <editor-content class="editor__content" :editor="editor"  />
    </template>
    <em v-else>
      Connecting to socket server …
