The missing DOM events

This is a bunch of web based dom events that can be triggered in the browser. But for backends like NodeJS.

It started out as ErrorEvent wasn't globally defined in NodeJS, so i wanted to create a polyfill for it. And since all DOM Events is pretty much the same. i polyfilled mostly all of them (80+ in fact).

Most of them won't even make since in a backend. But some of them are. Like the one Deno have for instance. Some are essential for a proper web Worker, it can for instance dispatch a ErrorEvent.

Someone who is building a macro/hotkey might want to dispatch keyboard / mouse events.

• All events extends Event
• If the event exist natively on global scope, then it will be used instead.

Install

missing-dom-events is an ESM-only module - you are not able to import it with require. If you are unable to use ESM in your project you can use the async import('missing-dom-events') from CommonJS to load missing-dom-events asynchronously.

npm install missing-dom-events

Use

import events from 'missing-dom-events'

const errorEvent = new events.ErrorEvent('error', {
  message: 'An error occurred',
  error: new Error('Something went wrong'),
  filename: 'script.js',
  lineno: 10,
  colno: 5,
  source: 'http://example.com/myscript.js',
  type: 'unhandledrejection'
})

worker.dispatchEvent(errorEvent)
