How to set up NGINX for referrer protection?

Question

Nginx

I want people to not be able to make hotlinks (integrate my js, css to their sites), only for my domain.
It would also be impossible to go through an empty referrer and open the code for viewing through a browser (js, css), but it was executed.
What to do with search engines, do they need them? How to take them into account?
Thank you!

Ask yourself - why? Who needs it, that code will look anyway. And does anyone really need your scripts and pictures?
And for your question - go to Google, there are a bunch of questions on StackOverflow for any relevant query.

location ~ ^/([a-zA-Z0-9\.\-]*)/(.*) {
    if ($http_referer !~ "^$1.*$"){
            return 403;
    }
}
