Event

Easily define event types for an EventTarget. Credits to this article.

Getting started

The following program defines play and stop events.

import { TypedEventTarget } from "@hydroperx/event";

class MediaPlayer extends (EventTarget as TypedEventTarget<{
    play: CustomEvent<MediaPlayerEvent>;
    stop: CustomEvent<MediaPlayerEvent>;
}>) {}

Note that event types must implement the Event interface, thus in the previous program CustomEvent is used; if there was no data, it could have just been Event itself.
