Chat based on Node.js using Redis Pub/Sub + socket.io

Simple application based to show Redis Pub/Sub mechanism together with Node.js and socket.io.

How to get the application running

• Redis must be installed and running.
  
• Node.js must be installed
  
• Node.js plugin socket.io must be in place (npm install socket.io).
  
• Node.js plugin redis installed (npm install redis).

Start via:

$ node app_redis.js

Fire up your favorite browser and go to “localhost”. Open more browser windows to see it in work.

Hint:
A non-redis version just based on socket.io can be started with:

$ node app.js
