Node Application structure for subdomains - node.js

Question

I am looking at building a website using node however my idea would be best with the use of subdomains. What i wanted to know is do i need to run each subdomain as a separate app and point to them with nginx?
Current Structure
- client
-- assets
--- js
--- css
--- img
- server
-- app
--- home
--- subapp1
--- subapp2
-- node_modules
-- server.js
-- config.js
The above structure is the thought that each app will run ny itself however they have common views that should be shared. Server.js will run them all. I just need to know if this is correct structure and if there is any cleaner or better alternative. Thanks

I'd suggest setting up Nginx to reverse proxy to 2 NodeJS apps. Run 1 app on port 8081 for example (service1) and the other on 8082 (service2) like this:
upstream service1 {
ip_hash;
server localhost:8081;
}
upstream service2 {
ip_hash;
server localhost:8082;
}
server {
listen 0.0.0.0:80;
server_name service1.mydomain.com;
location / {
index index.html index.htm;
proxy_pass http://service1;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
server {
listen 0.0.0.0:80;
server_name service2.mydomain.com;
location / {
index index.html index.htm;
proxy_pass http://service2;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
