• I have used lesscss only in my stylesheet public/css/styles.less because I couldn't find the less files of the bootstrap 2.3.2. Now, it's released the new version bootstrap 3.
• My knockout app is in public/js/app.js.
• When the app renders the html file, it passes as hardcoded the list of publications but the list doesn't effect the application. I did that in order to create 2 versions. The first one should have run in full ajax implementation and the second one should have load the list by one less request from the server. So, just ignore this part window.publications = [...];.
• Field Channels: I have created endpoint which provide a hardcoded list of channels http://localhost:3000/channels

file: routes/publication.js -> middleware: this.sendNewPublication

// trigger publication:new for websocket
app.emit('publication:new', {
	version : app.VERSION,
	response : req.publication,
	status: req.error ? 'ERROR' : 'OK',
	error: req.error
});

There is a listener at file: app.js

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

	app.on('publication:new', function (data) {

		setTimeout(function() {
			socket.emit('newPublication', data);
		}, 2000);

	});

	app.on('impressions:new', function (data) {

		socket.emit('newImpressions', data);

	});

});

• public/css/chart.less

The same as above. If you want to check the result you can do a request http://localhost:3000/get_new_impressions and see the results.
