This is a short example file of how an express app and socket.io work together with the CRUDS module.

express app with CRUDS

express = require("express")
app = express()

# app configuration etc...

server = http.createServer(app)
server.listen app.get("port"), ->
  console.log "Express server listening on port " + app.get("port")

# REST API and socket.io interface
socketio = require 'socket.io'
io = socketio.listen server

cruds = require("./cruds/lib/cruds")()
cruds.set "Entity", io # only websocket API
cruds.set "Entity2", app # only REST API
cruds.set "Entity3", app, io # both websocket and REST API
