Setup JS server and Spring boot app inside

[Arthur Harkivsky]

Hello!

How to setup JS server and Spring boot app inside?
Js server port = 5555, Spring app = 8888.
I have a domain name: xxxxxxxxxxxx.com
aws public ip yyyyyyyyyyyyyyy
aws public dns zzzzzzzzzzzzzzzzz

I need to set xxxxxxxxxxxx.com for js app
and api.xxxxxxxxxxxx.com for java app.

nginx

    server {
#        listen         80 default_server;
 #       listen         [::]:80 default_server;
        server_name zzzzzzzzzzzzzzzzz;
  #      root           /usr/share/nginx/html;
        location / {
            proxy_pass http://localhost:8888;
            proxy_set_header X-Forwarded-Host $host;
            proxy_set_header X-Forwarded-Server $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
    }

What should I place in route 53?
I have only new hosted zone for now.
