Sending a message to the client on connection using node and socket io

Question

Sending a message to the client on connection using node and socket io

How do i send a message to a specific client, more specifically, the client that has just connected to the app without broadcasting to the rest of the visitors that are already on the site?

   io.sockets.on('connection', function(client) {
   });

Seems to broadcast to everyone every time a new visitors connects.

node.js
websocket
socket.io

Answer 1

var io = require('socket.io').listen(80);

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

    socket.emit('greetings', { greeting:'hello, new visitor' });

    socket.on('greetingFromVisitor', function (data) {
        console.log(data);
    });

});
