NodeJS Express vhosts and updating app.js

Question

I just set up a NodeJS server and wanted to use the vhost function from Express to allow for easy project setup. I want to be able to create a new directory for a new project without going through the hassle of creating new subdomains etc.

Basically, I want to be able to reach project1 at node.domain.com/project1 and project2 at node.domain.com/project2.

I'm now running server.js, which is located in the root (node.domain.com/server.js) and contains:

var express = require('express'); 
var app = express(); 

app
.use(express.vhost('node.domain.com', require('./project1/app.js').app))
.use(express.vhost('node.domain.com', require('./project2/app.js').app))
.listen(3000);

It's all working fine, when I go to node.domain.com/project1 I get the results of ./project1/app.js but whenever I change something in any of the app.js files it requires a restart (Ctrl+C followed by node server.js) for it to update the changes.

And the contents of app.js are, for example:

var express = require('express'); 
var app = exports.app = express(); 

app.get('/project1', function(req, res){ 
    res.send('Hello World [/project1]');
});

Any idea why this is?

A thing to note is that I also run Apache on the same server, and I'm using this guide to allow both servers to run on port 80 (but accesible via different subdomains).

Oh! I feel dumb now, seems like I need to use something like forever, with its w flag.
