I'm also looking for this.
However I could not even emit new events, because I don't know how to access the EventEmitter offered by prestashop directly.
I'm looking to instantiate Grid javascript functionalities from the global 'prestashop' object, which are only available after a while.
I'd need to instantiate Grid components after this event is triggered:
EventEmitter.on('PSComponentsInitiated', () => { [...] })
but I need the EventEmitter js library in my code.
I wish I could access EventEmitter directly from prestashop like so:
window.prestashop.component.EventEmitter
but it's not possible, since the very same EventEmitter is loaded along with the other js components...
Bummer, I guess I'll need to load EventEmitter by my own..
