multiple node js app with different domain in same vps

Question

I have a Digitalocean VPS and 3 Nodejs (ExpressJs) application. Now I started all of them in same IP and different port like this: - 95.5.5.8:65001 - 95.5.5.8:65002 - 95.5.5.8:65003

But now I want when anybody writes app1.com, the first app 95.5.5.8:65000 shows to him like this:

app1.com -> load server in port 65001
app2.com -> load server in port 65002
app3.com -> load server in port 65003

All of the applications are in same VPS by the same IP, How can I do this, please?

you need to setup domains to point to vps and Nginx as reverse proxy to express applications there are many guides for this from digital ocean. — Gntem

You can implement this feature by following steps:

In domain setting page, map app1.com, app2.com and app3.com to 95.5.5.8.

In Nginx, configure 3 proxies for app1.com, app2.com and app3.com in directory /etc/nginx/conf.d/. Here is the proxy file /etc/nginx/conf.d/app1.conf for app1.com:

server {
    listen       80;
    server_name  app1.com;
    access_log   /var/log/nginx/app1_access.log;
    charset utf-8;

    location / {
        proxy_pass      http://95.5.5.8:65001;
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded_For $proxy_add_x_forwarded_for;
    }
}

Restart Nginx.
