Just do socket.emit()

"Just do socket.emit() "  where "socket" is someones socket

"Just do socket.emit() " how can i get the someones socket?

I try to use "io.sockets[someones socket's id].emit", but can not work...

* the socket's id save to a map at server.

I can do it.

io.sockets.socket(someone socket's id).emit("event name", msg);

test OK!

[Sergio Canales]

If you do socket.emit() you'll have the same as io.socket.sockets(socket.id).emit(), just get the socket object around on the 

.on('connection', function(socket){

});

 or 

.on('message', function(socket, data){

});

The other way would be to use rooms for that

Sorry for double post but I was not sure: by the way, is "io.sockets.socket(id)" cluster-proof?

[Kamil Krzyszczuk]

only if u sync by for example Redis, or socket.io-clusterhub, I recommend you first solution, second one break when there is reconnection, don't know why.

K thanks, good to know cause I noticed "io.sockets[id]" was not reliable when using cluster & redis (maybe that changed)

I am so sorry ,i didn't know what is "cluster-proof".

But i know "io.socket.sockets(socket.id).emit()" can do it.

A only send msg to B.

Hi N,

How can i do it by "rooms "?

[Phoungeun Vantho]

have a look at that url below that shows you how to broadcast or target a specific socket.

Hope that will help you.

You can store some kind of nick in an array, associated to the connection id. Later you can send messages to that connection using the nick. 

socket.on('connection', function (nick) {

   nicknames[nick] = socket.id; 

}

socket.on('message', function (text,nick) {                                                                                         

    io.sockets.socket(nicknames[nick]).emit('message',text);                                                                        

});

for sending to a specific socket use io.sockets.socket(socket.id)
where the 'socket' obj can be obtained from your client's connection event
io.sockets.on('connection', function (socket) {

...

});

be careful not to confuse between 'sockets' and 'socket'

Hi,M

Happy New Year!

Thank you for your help.

socket.join(session.username);
io.sockets.in("aFancyUsername").emit('yourEventName',{foo : "bar"});

I will try it.

Using expressjs and assuming that your application uses sessions and assigns usernames,you can make the user's socket join a particular room named as the user.

I am using a npm module named session.socket.io which makes the session object available inside socket.io callbacks.

You can find the example code here : https://gist.github.com/4378940

Hope this helps you.
