events-light

events-light

This is a lighter and small version of the builtin Node.js events with some removals, but no additional features. This module was designed to be a trimmed down polyfill for the events module in the browser, but it can also be used on the server.

Install

npm install events-light --save

Usage

var EventEmitter = require('events-light');

var myEventEmitter = new EventEmitter();

myEventEmitter.on('hello', function(name) {
    console.log('Hello ' + name);
});

myEventEmitter.emit('hello', 'World');

Difference from the Node.js events module

• Much smaller
• Slightly different error messages
• Removed:
  • EventEmitter.defaultMaxListeners
  • EventEmitter.listenerCount(emitter, eventName)
  • Event: 'removeListener'
  • Event: 'newListener'
  • emitter.prependOnceListener(eventName, listener)
  • emitter.setMaxListeners(n)
  • emitter.addListener(eventName, listener) (use on instead)
  • emitter.listenerCount(eventName)
  • emitter.listeners(eventName)
