Running multiple Node (Express) apps on same port
I have multiple Node applications (build on Express framework).
Now I have placed them like this -
/var/www/app1
/var/www/app2
/var/www/app3
Now I want to run these 3 apps on the same port (say 8080). Is that possible ?
One thing to note is that, Each app has common routes like these -
app.get('/', func...);
app.get('/about', func...);
app.post('/foo', func...);
app.post('/bar', func...);
Basically I want to do it like you can do with Apache/PHP setup.
So with a LAMP stack when you have -
/var/www/app1
/var/www/app2
/var/www/app3
You can easily access them as different apps from -
localhost/app1
localhost/app2
localhost/app3
Solution 1:
You can use app.use()
:
app
.use('/app1', require('./app1/index').app)
.use('/app2', require('./app2/index').app)
.listen(8080);
Solution 2:
You could run them as seperate apps listening to different ports and then have a proxy (like https://github.com/nodejitsu/node-http-proxy/ ) serving everything on 8080 depending on the requested URL.
like:
var options = {
router: {
'foo.com/baz': '127.0.0.1:8001',
'foo.com/buz': '127.0.0.1:8002',
'bar.com/buz': '127.0.0.1:8003'
}
};
Works like charm for me ( http://nerdpress.org/2012/04/20/hosting-multiple-express-node-js-apps-on-port-80/). I wasn't so keen on having them mounted as sub-apps, as suggested in the comments because i wanted them to run independently...
