The express router can handle this since 4.0

http://expressjs.com/en/api.html#router

http://bulkan-evcimen.com/using_express_router_instead_of_express_namespace.html

var express = require('express');
var app = express();
var router = express.Router();

// simple logger for this router's requests
// all requests to this router will first hit this middleware
router.use(function(req, res, next) {
  console.log('%s %s %s', req.method, req.url, req.path);
  next();
});

// this will only be invoked if the path ends in /bar
router.use('/bar', function(req, res, next) {
  // ... maybe some additional /bar logging ...
  next();
});

// always invoked
router.use(function(req, res, next) {
  res.send('Hello World');
});

app.use('/foo', router);

app.listen(3000);

Previous answer (before express 4.0) :

The express-namespace module (dead now) used to do the trick :

https://github.com/visionmedia/express-namespace

require('express-namespace');

app.namespace('/myapp', function() {
        app.get('/', function (req, res) {
           // can be accessed from something.com/myapp
        });
});
