Forwarding port 80 to 8080 using NGINX [closed]

As simple as like this,

make sure to change example.com to your domain (or IP), and 8080 to your Node.js application port:

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_set_header   X-Forwarded-For $remote_addr;
        proxy_set_header   Host $http_host;
        proxy_pass         "http://127.0.0.1:8080";
    }
}
