Property 'clientX' does not exist on type 'Event'. Angular2 Directive

Question

I'm trying to listen to the X position of my mouse in an Angular2 Directive like this:

@HostListener('mousemove', ['$event'])
onMousemove(event: Event): void  { 
  console.log(event.clientX)
}

but I get the error

Property 'clientX' does not exist on type 'Event'.

This is odd because this listener

@HostListener('mousemove', ['$event'])
onMousemove(event: Event): void  { 
  console.log(event)
}

logs out an event object

Why can I not access event.clientX?

Change the parameter type

onMousemove(event: MouseEvent): void  { 
  console.log(event.clientX)
}

I have a similar issue, I tried with several different types, including `MouseEvent` that is the one I get in my console.log() but it keeps saying: `Property 'layerY' does not exist on type 'MouseEvent'` – Diego Ortiz Sep 30 '19 at 17:20

Interesting. It not a standardized property but according to https://developer.mozilla.org/en-US/docs/Web/API/UIEvent/layerY all browsers support it. Check your browsers changelog if it was discontinued there. – Günter Zöchbauer Sep 30 '19 at 17:27
