  24. 11/7/12 Real Time and MVC with GeddyJS HOW DOES IT WORK? ON THE SERVER SIDE: geddy sees the realtime flag in your config file copies your models over to a public js file sets up listeners for each model's lifecycle events proxies those lifecycle events to socket.io file://localhost/Users/derickson/dev/presentations/2012/qconsf/index.html?print‑pdf#/1 24/30
