See Migration Guide for details.

✨ New Features

■ Event class is available

Previously, this package had not exported Event class as prefers using the native Event class. Since this version, this package exports it.

import { EventTarget, Event } from "event-target-shim";

const target = new EventTarget();
target.dispatchEvent(new Event("foo"));

■ signal option on EventTarget.prototype.addEventListener is available

It's a new feature that was added to the standard recently: whatwg/dom#919

import { EventTarget, Event } from "event-target-shim";
import { AbortController } from "abort-controller";

const target = new EventTarget();
const ac = new AbortController();

target.addEventListener("foo", listener, { signal: ac.signal });

// Remove the listener
ac.abort();

■ Customizing error/warning handling

Since this version, if a listener threw an exception, it causes the uncaughtException event on Node.js or the error event on window. Also, if an operation was ignored silently, it prints warnings with console.warn.

You can customize this behavior.

import { setErrorHandler, setWarningHandler } from "event-target-shim";

setErrorHandler((error) => {
  // Do something.
});
setWarningHandler((warning) => {
  // Do something.
});
