NodeSP (Node Server Pages) is a proof of concept on using Node.js as a web server serving dynamic content generated from .js scripts akin to PHP or other CGI scripts.

Put the above nodesp.js in your node_modules folder and then run the following nodespserver.js:

var http = require('http'),
    nsp  = require('nodesp');

http.createServer(function (req, res) {
    nsp.run(req, res);
}).listen('8111');

Finally create your test.js:

response.body = '<h1>Hello World!</h1>';

If you then call localhost:8111/test.js you should see "Hello World!" printed in large, friendly letters.
