Socket.io only sends data to the client that makes the request
I am sending data to all clients, but I only need to send data to one client ( who are making the request ).
app.post(.....){
myModel.save(function (err) {
if (err) return handleError(err);
///send to all
io.sockets.emit("ev", { ...... });
//// send to one client
......
});
}
There is a function named io.sockets.emit
but not io.socket.emit
.

I am assuming that in the post method you have identified the user or session.
This way, you can create a room for each user to emit afterwards.
client.js
var room = "#usernameRoom";
socket.on('connect', function() {
socket.emit('privateroom', room);
});
socket.on('privatemessage', function(data) {
console.log('Incoming private message:', data);
});
server.js
io.sockets.on('connection', function(socket) {
var socket_room;
socket.on('privateroom', function(room) {
socket_room = room;
socket.join(room);
});
socket.on('disconnect', function() {
if (socket_room) {
socket.leave(socket_room);
}
});
});
app.post(.....){
myModel.save(function (err) {
if (err) return handleError(err);
///send to all
io.sockets.emit("ev", { ...... });
//// send to one client
// now, it easy to send a message to just the clients in a given private room
privateRoom = "#usernameRoom";
io.sockets.in(privateRoom ).emit('privatemessage', 'Never reveal your identity!');
});
}
hope it helps
