Use res.json. For instance:

function(req,res) {
  res.json({ user: 'tobi' })
}

Check out Heroku's example tutorial. I think it does exactly what you are asking for in terms of JSON encoding + throws in Web Sockets. https://devcenter.heroku.com/articles/node-websockets

If you use Express in node.js, here is the way to send json object as response:

app.get('/test', function(req, res, next) {
  res.json({ message: 'Hello World' });
});

Then in JS on your html page html, if you use jQuery:

$.ajax({
  url: '/test',
  complete: function(data) {
    console.log(data);
  }
});

Feel free to experiment with stuff, as well use Dev Tools in Chrome, experimentation - helps a lot to understand what and how it works.
