# 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

pietern

require 'rubygems'
require 'sinatra'
require 'redis'

# To use, simply start your Redis server and boot this
# example app with:
#   ruby example_note_keeping_app.rb
#
# Point your browser to http://localhost:4567 and enjoy!
