io.sockets.socket(socket_id).emit() - has no method 'socket'

Question

im running a nodejs server + express + socket.io version 1.0.4 and everything works as expected in my app, but i just cant emit a message from server side to client side via

Answer 1

In 1.0 you should use:

io.sockets.connected[socketid].emit();

to emit to a specific client.

socket_server.sockets.socket(socket_id).emit(); 

has been replaced in socket.io 1.0.

Answer 2

in 1.x version, u can find in docs a list of migration tips from oldest version, especifically

Broadcasting to all clients in default namespace

Previously:

io.sockets.emit('eventname', 'eventdata');

Now:

io.emit('eventname', 'eventdata');

red the docs here

Answer 3

Change your last part of code to:

var io = require('socket.io').listen(server);
io.on('connection', function(socket) {
    socket.emit('msg',data);
    //to only that client
    io.sockets.emit('msg',data);
    //to all sockets.
}

io is your socket_server. And you listen for connections to it, not to its sockets.

Answer 4

In version >= 1.0 you should use:

io.to(socket.id).emit();

where socket.id is the id as string. The solution was found by victorwoo in following thread https://github.com/socketio/socket.io/issues/1618

Note: The solution describe above by Tony Chen

io.sockets.connected[socketid].emit();

didn't worked for me, since io.sockets.connected is an array of socket objects and not string (id)
