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("https://stackoverflow.com/", function (req, res) {
// can be accessed from something.com/myapp
});
});
