Concatenate strings and variable values in angular html template

Just use the simple quotes ' and + sign inside the double quotes of the html attribute value. See the value of the href attribute below:

<div class="float-right mt-1">
  <a
    *ngIf="snippet.public"
    type="button" class="btn btn-light btn-sm float-right"
    href="mailto:?subject=Code snippet: &body=https://www.codever.dev/snippets/"
    title="Share link to snippet via Email">
    <i class="far fa-envelope"></i> Email
  </a>
</div>
