Socket.io simple cheat sheet

socket.js

io.on('connection', function(socket){
  /* 'connection' is a special event fired on the server when any new connection is made */
})

socket.on('disconnect', function(){
  /* When this individual socket has disconnected, this special event fires */
})

/* This will send the event 'foobar' with the data to 
  every connected to socket */
io.emit('foobar',data)

/* This will send the event 'foobar' with the data object to 
  every connected socket EXCEPT for the socket this is called on */
socket.broadcast.emit('foobar',data) 

socket.on('foobar', function(data){
/* Fires whenever this socket receives an event 'foobar'.
  You can access the data received inside this callback*/  
})

/* This will send the event 'foobar' with the data to the server */
socket.emit('foobar',data) 

socket.id // A unique string identifying this socket connection
