Release notes

Package name: events

• 3.3.0 - 2021-02-27
  

  • Support EventTarget emitters in events.once from Node.js 12.11.0.

    Now you can use the events.once function with objects that implement the EventTarget interface. This interface is used widely in
    the DOM and other web APIs.

    var events = require('events');
    var assert = require('assert');

    async function connect() {
    var ws = new WebSocket('wss://example.com');
    await events.once(ws, 'open');
    assert(ws.readyState === WebSocket.OPEN);
    }

    async function onClick() {
    await events.once(document.body, 'click');
    alert('you clicked the page!');
    }

• 3.2.0 - 2020-07-22
  

  • Add events.once from Node.js 11.13.0.

    To use this function, Promises must be supported in the environment. Use a polyfill like es6-promise if you support older browsers.

• 3.1.0 - 2020-01-08
  

  events now matches the Node.js 11.12.0 API.

  • pass through return value in wrapped emitter.once() listeners

    Now, this works:

    emitter.once('myevent', function () { return 1; });
    var listener = emitter.rawListeners('myevent')[0]
    assert(listener() === 1);

    Previously, listener() would return undefined regardless of the implementation.

    Ported from nodejs/node@acc506c

  • Reduce code duplication in listener type check (#67 by @ friederbluemle).

  • Improve emitter.once() performance in some engines

• 3.0.0 - 2018-05-25
  

  This version drops support for IE8. events no longer includes polyfills
  for ES5 features. If you need to support older environments, use an ES5 shim
  like es5-shim. Both the shim and sham
  versions of es5-shim are necessary.

  • Update to events code from Node.js 10.x
    • (semver major) Adds off() method
  • Port more tests from Node.js
  • Switch browser tests to airtap, making things more reliable
