A simple abstraction for creating your own event-emitting objects. Uses the standard EventEmitter implementation in Node.js

const createEventEmitter = require("create-event-emitter");

let doorbell = createEventEmitter({
	ring: function ringDoorbell(noise = "RING RING!") {
		this.emit("ringing", noise);

doorbell.on("ring", (noise) => {
	console.log(`Doorbell is ringing: ${noise}`);

doorbell.ring(); // Prints: "Doorbell is ringing: RING RING!"



Creates a new event-emitting object with the specified properties. The resulting emitter has the standard EventEmitter API.

  • properties: The properties that the new event-emitting object should have. These are simply merged into the emitter object.

emitter.emit(eventName, [... arguments])

Emits the specified event on the emitter, triggering the associated event handlers, if any. You'd usually call this from within a method on the emitter, as this.emit.

  • eventName: The name of the event to emit/trigger.
  • ... arguments: The arguments to pass to the event handler. Any amount is allowed.

Note that this is part of the API of the standard Node.js EventEmitter, as documented here.
