Node.js HTTP Server One Liner

One liner to create a Node.js HTTP server:

1
require('http').createServer(function (req, res) { res.end('OK'); }).listen(3000);

Print out the process ID instead:

1
require('http').createServer(function (req, res) { res.end('' + process.pid); }).listen(3000);

This is useful with the worker process when implementing the cluster module.
