title: Vue - watch for changes on this.$el.clientWidth
body: <p>Is it possible to watch for changes on components element clientWidth (this.$el.clientWidth)?
  Something like:</p>
  
  <pre><code> this.$watch(
          () =&gt; {
              return this.$el.clientWidth;
          },
          (newWidth, oldWidth) =&gt; {
              console.log(newWidth);
          }
      )
  </code></pre>
