Flexibles Routing von Node.js

[code]var http = require('http');
var url = require('url');
function start(route) {
    var onRequest = function (request, response) {
        var pathname = url.parse(request.url).pathname;
        console.log("Request for " + pathname);
        route(pathname);
        response.writeHead(200, { "Content-Type" : "text/plain"});
        response.write("Hello Zhang Shan");
        response.end();
    }
    http.createServer(onRequest).listen(8888);
    console.log('Server has started');
}
exports.start = start;

[code]var server = require('./server');
var router = require('./router');
server.start(router.route);
