These + * objects expose an `eventEmitter.on()` function that allows one or more + * functions to be attached to named events emitted by the object. Typically, + * event names are camel-cased strings but any valid JavaScript property key + * can be used. + * + * When the `EventEmitter` object emits an event, all of the functions attached + * to that specific event are called _synchronously_. Any values returned by the + * called listeners are _ignored_ and discarded. + * + * The following example shows a simple `EventEmitter` instance with a single + * listener. The `eventEmitter.on()` method is used to register listeners, while + * the `eventEmitter.emit()` method is used to trigger the event. + * + * ```js + * const EventEmitter = require('events'); + * + * class MyEmitter extends EventEmitter {} + * + * const myEmitter = new MyEmitter(); + * myEmitter.on('event', () => { + * console.log('an event occurred!'); + * }); + * myEmitter.emit('event'); + * ``` + * @see [source](https://github.com/nodejs/node/blob/v18.0.0/lib/events.js) + */ +declare module 'events' { + // NOTE: This class is in the docs but is **not actually exported** by Node. + // If https://github.com/nodejs/node/issues/39903 gets resolved and Node + // actually starts exporting the class, uncomment below. + + // import { EventListener, EventListenerObject } from '__dom-events'; + // /** The NodeEventTarget is a Node.js-specific extension to EventTarget that emulates a subset of the EventEmitter API. */ + // interface NodeEventTarget extends EventTarget { + // /** + // * Node.js-specific extension to the `EventTarget` class that emulates the equivalent `EventEmitter` API. + // * The only difference between `addListener()` and `addEventListener()` is that addListener() will return a reference to the EventTarget. + // */ + // addListener(type: string, listener: EventListener | EventListenerObject, options?: { once: boolean }): this; + // /** Node.js-specific extension to the `EventTarget` class that returns an array of event `type` names for which event listeners are registered. */ + // eventNames(): string[]; + // /** Node.js-specific extension to the `EventTarget` class that returns the number of event listeners registered for the `type`. */ + // listenerCount(type: string): number; + // /** Node.js-specific alias for `eventTarget.removeListener()`. */ + // off(type: string, listener: EventListener | EventListenerObject): this; + // /** Node.js-specific alias for `eventTarget.addListener()`. */ + // on(type: string, listener: EventListener | EventListenerObject, options?: { once: boolean }): this; + // /** Node.js-specific extension to the `EventTarget` class that adds a `once` listener for the given event `type`.
