Watch height of an element in VueJS

Question

Is there any way to set a watcher on the height of an element in VueJS?

I am trying to fix the filters part on a search result page. but if the results change there is no way to find about it and unfix the filters.

You could use the ResizeObserver and integrate it into your Vue-Component

function observeHeight() {
  const resizeObserver = new ResizeObserver(function() {
     console.log("Size changed");
  });

 resizeObserver.observe(document.getElementById('yourId'));
}

function changeHeight() {
  var elem = document.getElementById('yourId');
  
  console.log('...loading data...')
  setTimeout(function(){ 
    elem.style = "height: 200px";
  }, 3000);
  
}

observeHeight();
changeHeight();

#yourId {
  background-color: beige;
  height: 100px;
}

<div id="yourId">
  
</div>
