How can I configure multiple sub domains in Express.js or Connect.js

Question

I am used to working on httpd ( Apache ) which provides a way to configure subdomains which is mapped to a directory. How can I do the same thing in Connect.js/Express.js ? I see that the only thing that I have is routes which I am not sure how I can use to configure sub domains. I have subdomains like m.mysite.com, sync.mysite.com

Can someone help ?

Or alternatively you could use vhost.

Then, create several sites in their own directory and export the express app, eg. /path/to/m/index.js:

var app = express() /* whatever configuration code */ exports.app = app // There is no need for .listen() 

And then handle all requests with the following app:

var vhost = require('vhost');  express() .use(vhost('m.mysite.com', require('/path/to/m').app)) .use(vhost('sync.mysite.com', require('/path/to/sync').app)) .listen(80) 

Note that /path/to/m and /path/to/sync can be absolute paths (as written above) or relative paths.
