How to prevent opening files with a certain extension?

Question

Nginx

Whether prompt there is an option to forbid access to certain files.
There is a static/plugins/ folder on the server.
It contains plugins for the site, for example, a slider or select styling. These folders usually contain a lot of extra files, documentation, demo version, etc. And it is JS, CSS, image files that are important, the rest I would like to close, restrict access to them.
Is it possible to make such a setting?

Answer 1

Of course, I think that the following construction can help:

# Указываем расширения файлов, которые можно использовать в каталоге:
location ~* ^/static/plugins/.+\.(css|js|png)$ { 
  root /var/www/site.ru/;
}

# Следующий локейшен будет запрещать доступ в этот каталог для всех, не указанных ранее, расширений файлов
location ~* ^/static/plugins/ { 
  return 403;
}
