Connect / node.js - creating a simple server


I'm trying to get connect / node.js to work together nicely and simply. I have the following (in Coffeescript):

connect = require('connect')
io = require('socket.io')

server = connect.createServer(
    connect.favicon()
  , connect.logger()
  , connect.static(__dirname + '/public')
).listen(8000)

socket = io.listen(server)
socket.on 'connection', (socket) ->
  socket.send({ hello: 'world' })

But I keep getting the following error:

TypeError: Cannot call method 'listeners' of undefined

It seems the server is not being initialized in time for the socket to start listening.

Compare with:

io = require ("socket.io")
http = require('http')

server = http.createServer()

server.listen(8000)

socket = io.listen(server)

socket.on 'connection', (socket) ->
  socket.send({ hello: 'world' })

Which does work?


Solution

  • Probably because .listen() returns something else. It should work if you rewrite your code like this:

    connect = require('connect')
    io = require('socket.io')
    
    server = connect.createServer(
        connect.favicon()
      , connect.logger()
      , connect.static(__dirname + '/public')
    )
    server.listen(8000)
    
    socket = io.listen(server)
    socket.on 'connection', (socket) ->
      socket.send({ hello: 'world' })
