Restrict access to Node.js-based HTTP server by IP address

Question

How can I restrict access by IP address in a Node.js HTTP server application?

I\'m looking for something like this:

Deny from all
Allow from ..

I'm not sure how bulletproof is this approach, but here it is, collected from answers around the web:

var http = require('http');
http.createServer(function (req, res)
{
    var ip = req.ip || req.connection.remoteAddress || req.socket.remoteAddress || req.connection.socket.remoteAddress;
    if (ip == '127.0.0.1') // exit if it's a particular ip
        res.end();
...

Please, someone more proficient in node - correct me
