transitionstart event in React component

Question

I am trying to add a callback function in my React component to capture the transitionstart event. Apparently, only transitionend is supported. Do you know any workaround?

<div
    className="super-component--animated"
    { /** Not supported **/ }
    onTransitionStart={() => {
        this.changeAnimationStatus(true);
    }}
    onTransitionEnd={() => {
        this.changeAnimationStatus(false);
    }}

     Hello Friends!
</div>

Answer 1

All unsupported event in React should be handled vanilla style.

const MyComp = () => {
...
 const handler = () => {
 ref.current.addEventListener('your_event', () => {...})
 }
 return <div ref={ref}/>
}
