transitionend event listener.
This module is based on on-transition-end, which no longer seems to be maintained and is not working properly. Also, it automatically infers the timeout based on the transition duration.
$ npm install proper-on-transition-end
import onTransitionEnd from 'proper-on-transition-end'; // or const onTransitionEnd = window.onTransitionEnd; const cancelOnTransitionEnd = onTransitionEnd(element, [options,] callback)
element: The element that is transitioning.
options: You can pass a few options here:
timeout: This is automatically calculated for you, based on the longest transition of the element, using
longest-transition. Still, you can override that and pass the
gracePeriod: There is an implicit grace period of
100milliseconds before the event times out, but you can tweak it using this option.
callback: The callback that is called when the transition ends.
cancelOnTransitionEnd will remove the listener and cleanup the timers.
