Node.js basic routing

const http = require("http");

var routes = {
  "/": function index(request, response) {
    response.writeHead(200);
    response.end("Hello, World!");
  },
  "/foo": function foo(request, response) {
    response.writeHead(200);
    response.end('You are now viewing "foo"');
  },
};

function index(request, response) {
  response.writeHead(200);
  response.end("Hello, World!");
}
http
  .createServer(function (request, response) {
    /*
    if (request.url === "/") {
      return index(request, response);
    }
    response.writeHead(404);
    response.end(http.STATUS_CODES[404]);
    */

    if (request.url in routes) {
      return routes[request.url](request, response);
    }
    response.writeHead(404);
    response.end(http.STATUS_CODES[404]);
  })
  .listen(1337);

Testing :

http://127.0.0.1:1337/
http://127.0.0.1:1337/foo
