Nginx Reverse Proxy

Use following settings for setting up an reverse proxy in Nginx for HTTPS.

server {
        listen 443 ssl;
        server_name status.isu.kim;
        ssl_certificate /etc/letsencrypt/live/status.isu.kim/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/status.isu.kim/privkey.pem;

        location / {
                proxy_pass                          http://127.0.0.1:3000;
                proxy_set_header Host               $host;
                proxy_set_header X-Real-IP          $remote_addr;

                proxy_set_header X-Forwarded-For    $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto  https;

        }
}

Disclaimer

The ReactJS template for this website was made it possible by themesberg. I cut off some redundant codes and just made this as a bootstrap single page.
I am not a web developer, nor a backend developer. Therefore, the codes might be awful.
The status check is done by nc -zv from the backend API. Therefore, this has no capability to check health status. This will just check ports open.
The server will compare passwords in plain text. Tried using SHA or hash, but had lack of experience with ReactJS and frontend. (Just was too lazy to implement a DB in backend)

Contributing and Issues

If you found any vulnerabilities, I guess there will be some, please PR. I have seen the ReactJS warning about CVEs, but I am too lazy to update them and fix their dependencies. Also, I do not wanted to break the program as well.
Report issues in the issues section for help.
