# EventDispatcher

Performant, opinionated event dispatcher.

## Installation

`npm install @pdw.io/event-dispatcher`

## Usage

Below is a very minimal example. The main thing to note is that the "event names" are strictly numbers (Enum keys in this case), this is where the performance comes from.

```typescript

import { EventDispatcher } from '@pdw.io/eventdispatcher';

export enum DialogEventName {

  OPEN,

  CLOSE,

}

class Dialog extends EventDispatcher {

  private open = false;

  toggle() {

    this.open = !this.open;

    const eventToSend = this.open ? DialogEventName.OPEN : DialogEventName.CLOSE;

    this.dispatchEvent(eventToSend);

  }

}

const dialog = new Dialog();

dialog.addEventListener(DialogEventName.OPEN, callback);

```
