Event

Getting started

The following program defines play and stop events.

import { EventRecord, EventTarget } from "@hydroperx/event";

// media player
class MediaPlayer extends EventTarget {
    // declare events
    declare [EventRecord]: {
        play: MediaPlayerEvent,
        stop: MediaPlayerEvent,
    };
}

Extending MediaPlayer with more events:

// media player
class MoreSpecializedPlayer extends MediaPlayer {
    // declare events
    declare [EventRecord]: MediaPlayer[typeof EventRecord] & {
        // more events...
    };
}

Note that event types must implement the Event interface.
