# Description: Simple demo to showcase Redis PubSub with EventMachine
#
# Update 7 Oct 2010:
# - This example does *not* appear to work with Chrome >=6.0. Apparently,
#   the WebSocket protocol implementation in the cramp gem does not work
#   well with Chrome's (newer) WebSocket implementation.
#
# Requirements:
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby

Yeoman generators with Browserify

Browserify is a tool that allows us to write node-style modules that compile for use in the browser. Like node, we write our modules in separate files, exporting external methods and properties using the module.exports and exports variables

generator-browserify is a generator with a Browserify setup, offering choices between Gulp or Grunt and Foundation or Bootstrap.

generator-angular-with-browserify is a generator for bundling Angular.js with Browserify

To enable window.gc() on Chrome browser console you just need to start Chrome like this:

> /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --js-flags="--expose-gc" --enable-memory-info

Those flags enable the following console API, very usefull to debug memory leaks: 

> console.memory // print memory information
> window.gc() // force garbage collection
