event-handler

Create an event emitter by either creating a new object or mixin in an existing object or constructor.

// fresh emitter object
var emitter = eventHandler();

var obj = {};

// mixin existing object
eventHandler(obj);

var Constructor = function () {};

// mixin existing constructor
eventHandler(Constructor);

import * as eventHandler from 'c2-event-handler';

// es6 class inheritance
class emitter extends eventHandler.EventConstructor {
    constructor() {
        super();
    }
}

Once you've created the emitter, use the methods to turn on or off functions or to emit events.

obj.on('start stop', function (status) {
    console.log('the program has ' + status);
});

obj.off('stop');

obj.emit('start', 'started'); // the program has started
