Since http://qvacua.com consists of only static files, the following node.js static HTTP server comes in handy

HOST = null; // null => localhost
PORT = 8000;

HTTP_STATUS_OK = 200;
HTTP_STATUS_NOT_FOUND = 404;

var http = require("http"),
    url = require("url"),
    path = require("path"),
    fs = require("fs");

function writeNotFound(response) {
    response.writeHead(HTTP_STATUS_NOT_FOUND, {
        "Content-Type": "text/plain"
    });
    response.end("Not Found");
}

function writeBinary(data, response) {
    response.writeHead(HTTP_STATUS_OK);
    response.write(data, "binary");
    response.end();
}

function writeIndexHtml(filename, response) {
    var indexFilename = path.join(filename, 'index.html');

    fs.exists(indexFilename, function (exists) {
        if (!exists) {
            writeNotFound(response);
            return;
        }

        fs.readFile(indexFilename, function (error, data) {
            writeBinary(data, response);
        });

    });
}

var server = http.createServer(function (request, response) {
    var uri = url.parse(request.url).pathname;
    var filename = path.join(process.cwd(), uri);

    fs.stat(filename, function (error, stats) {
        if (error) {
            writeNotFound(response);
            return;
        }

        if (stats.isDirectory()) {
            writeIndexHtml(filename, response);
            return;
        }

        fs.readFile(filename, function (error, data) {
            writeBinary(data, response);
        });
    });
});

server.listen(PORT, HOST);
console.log("Server @ http://" + (HOST || "localhost") + ":" + PORT);

By default index.html will be served when the URL directs to a folder. It does not have error handling whatsoever: sufficient for development.
