title: Vue watch for pending http requests
body: <p>When mounting a component, it starts 4 http requests (using Axios) to get the appropriate data it needs. Is there a way to watch for any pending HTTP requests?</p>
  <p>So basically:</p>
  <p>Any pending HTTP requests?</p>
  <p>yes -&gt; Loading=true</p>
  <p>no -&gt; Loading=false</p>
