Node.js : Load .js and .css files included in HTML file without Express/frameworks

How can you load the .js .csv and .css files included within an HTML file, displayed with Node.js? (Without frameworks like Express)

E.g. <script src="clock.js"></script>

In Firefox, it shows that the page, fs.readFile('./index.html'), is requesting clock.js, jquery.js, etc. as html files, probably because of response.writeHead being text/html.

Is there a way to do:

if file included in index.html = .js
set writeHead to application/javascript

if file included in index.html = .css
set writeHead to text/css

Without specifying in advance what files index.html may include? (e.g. if in the future, index.html also uses menu.js, you wouldn't need to update the node.js script)

Is there a way to see what files are being requested by index.html, then modify the headers of those files (e.g. .js has application/javascript)?

Is this the sort of thing you are looking for?

    var http = require("http");
    var fs = require("fs");
    var path = require("path");
    var server = http.createServer(function(request, response) {
        //typically what will happen here is that you will see
        //see the request for the page (index.html?) first and
        //then the browser's subsequent requests for js, css etc files
        var url = request.url;
        var file = //do something clever to extract the file name from the url ( url.split("/")?)
        var html = fs.readFileSync(file,"utf-8");
        //probably want to check the file extension here to determine the Content-Type
        response.writeHeader(200, {"Content-Type": "text/html"});  
        response.write(html);  
        response.end();  
    });

server.listen(8081);
console.log("Server is listening");

A bit agricultural, and you would probably run in to all sort of problems with routing - but its the idea.
