DOM EventTarget compatible events interface

dom-event-target

DOM EventTarget compatible events interface

Install

$ npm install --save dom-event-target

Usage

var EventTarget = require('dom-event-target');
var target = new EventTarget()
target.addEventListener('myEvent', function (data) {
  console.log('myEvent fired', data)
})
target.send('myEvent', {foo: 'bar'})

Caveats

The true EventTarget in the browser prevents the addition of duplicate handlers for an event. This library does not implement deduping. Duplicate handlers will be removed when removeEventListener is called with matching arguments.

The useCapture argument and the dispatchEvent method are not implemented. dom-event-target provides an EventTarget API, not a full implementation of DOM events.
