You should be able to do such a thing using Socket.io. First, you will need to install it with npm install socket.io. From there, in your code you will want to have var io = require(socket.io);

You can see more in-depth examples given by Socket.IO

You could use something like this on the server:

var express = require('express');
var app = express();
var server = require('http').createServer(app);
var io = require('../..')(server);
var port = process.env.PORT || 3000;

server.listen(port, function () {
  console.log('Server listening at port ' + port);
});

app.use(express.static(__dirname + '/public'));

io.on('connection', function (socket) {
    socket.emit('EVENT_NAME', {data});
});

And something like this on the client:
