RewriteEngine On
RewriteCond %{HTTP_HOST} ^yourdomain\.com [NC]
RewriteCond %{SERVER_PORT} !^80$
RewriteRule ^(.*)$ http://yourdomain.com/$1 [R=301,L]

server {
    listen 80;
    server_name yourdomain.com;

    location / {
        proxy_pass http://localhost:your_port;
        proxy_set_header Host $host;

        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

const url = new URL(window.location.href);
url.port = '';
window.history.replaceState({}, document.title, url.toString());

server {
    listen 80;
    server_name yourdomain.com;
