This is a configuration file that allows you to customize the way your app talks to clients over Socket.IO.
It provides transparent access to Sails' encapsulated pubsub/socket server for complete customizability. In it you can do things on the list below (and more!).
Socket.IO configuration options can be found here.
See sails.config.sockets for all available options.
An example of this file can be found in our sample app repo, here.
