got-events

got-events

Simple events for simple objects. Three methods to rule'em all: .on, .off, .trigger. Lots of fun.

Install (coming soon)

npm install --save got-events

Usage

Three options:

1. Function:

var evHandler = require('got-events')();

1. Extend object:

require('got-events').extend(simpleObject);

Optionally preserving old attributes:

1. Singleton:

var evHandler = require('got-events').singleton;
