sweet-event-emitter v0.1.0

Installation

Get started by installing the package:

npm install sweet-event-emitter
# OR
yarn add sweet-event-emitter

Usage

The event emitter provides a simple yet rich API to work with events.

Creating an event emitter

import { EventEmitter } from 'sweet-event-emitter';

const emitter = new EventEmitter();

Listening to events

emitter.on('event', () => {
  console.log('Event fired!');
});

// Events can have parameters too
emitter.on('event-with-params', (param1, param2) => {
  console.log('Event fired with params:', param1, param2);
});

Listening to events once

// This will only fire once
emitter.once('event', () => {
  console.log('Event fired!');
});

Emitting events

emitter.emit('event');

// Emit events with parameters
emitter.emit('event-with-params', 'param1', 'param2');

Removing listeners

const listener = () => {
  console.log('Event fired!');
};

emitter.on('event', listener);

// Remove a specific listener
emitter.off('event', listener);

Removing all listeners

emitter.removeAllListeners('event');

Get all listeners

const listeners = emitter.listeners('start');
