voltrevo-event-emitter

My utopian vision for simple eventing.

An event emitter that probably does everything you actually need in only 70 lines of code.

Install

$ npm install --save voltrevo-event-emitter

Usage

'use strict';
 
var EventEmitter = require('voltrevo-event-emitter');
 
var ee = EventEmitter();
 
// events are asynchronous
 
ee.emit('foo', 'bar');
 
ee.on('foo', function(value) {
  console.log(value); // bar
});
 
// .once works as usual
 
ee.emit('boom');
ee.emit('boom');
 
ee.once('boom', function() {
  console.log('boom'); // only one boom
});
 
// .on and .once return Collection handles, which have .remove
 
ee.emit('unicorn');
 
var listener = ee.on('unicorn', function() {
  console.log('A wild unicorn appeared!'); // this never happens
});
 
listener.remove();
