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 need to allow access to the site for only a few IP addresses. How can I do this?

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
