Redirect domain to different ports based on subdomain - AWS

Question

I have a EC2 instance on which I am running a React App and a domain from Route 53, for example xyz.com.

For this xyz.com I have two subdomains say www.xyz.com and demo.xyz.com.

Now, traditionally my React App serves on PORT 3000 on this instance. I have configured the IP with the PORT using nginx on my instance, something like this 192.1.1:3000. Now whenever I hit this domain (www.xyz.com) I am redirected to 192.1.1:3000.

For example, if I have two versions of my app called dev and prod. dev serves on PORT 3000 and prod serves on PORT 3002.

I want to www.xyz.com to redirect to 3000 and demo.xyz.com redirect to 3002. Both of these are from the same DNS provider.

Is there a away to achieve this?

try this way:

 server {
        server_name www.xyz.com;
        location / {
            proxy_pass       http://192.1.1:3000;
        }
 }
 server {
        server_name demo.xyz.com;
        location / {
            proxy_pass       http://192.1.1:3002;
        }
 }

( add extra parameters if you want to add regarding the request, header etc )

I hope this answer helps you.
