  • Follow nginx install process as mentioned here: https://www.nginx.com/resources/wiki/start/topics/tutorials/install/
  • on successful installation navigate to /etc/nginx
  • new installations don't come with "site-available" and "site-enabled" folder, so create them
  • /etc/nginx/nginx.conf is the entry point for the server. Include enabled sites configurations with "include /etc/nginx/sites-enabled/*;" in "http" section.
  • navigate to "sites-available" folder and add "express.conf" there. It still won't be recognized by server as it's not in "sites-enabled" folder.
  • create symbolic link to "sites-enabled" with " sudo ln -s /etc/nginx/sites-available/express.conf /etc/nginx/sites-enabled " - its important to create symbolic link from root ("/") or else empty file gets created.
  • check "nginx.conf" with "sudo nginx -t" command.
  • If everything is right, restart nginx using: "sudo systemctl restart nginx".
  • Check nginx's status using "sudo systemctl status nginx".

The following code in express.conf:

        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-Nginx-Proxy true;
        proxy_pass http://127.0.0.1:3000/;
        proxy_redirect off;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_redirect off;
        proxy_set_header X-Forwarded-Proto $scheme;

does the task of forwarding traffic coming for "www.js-server.com" to "localhost:3000". Plus, it sets the proxy headers.
