Nginx - gzip_static and proxy_pass - proper way to serve static gzip files

What is the best way to serve static gzip files using nginx of a server that runs thru a proxy?

I have a nodejs app running thru a proxy_pass http://127.0.0.1:3000/;

I'd like to pass through nodejs (without touching) to static gzip files when possible.

Current configuration:

• project's folder with files and their compressed copies
• nodejs project running on 127.0.0.1:3000

• the following short version of my nginx.conf `

  http {
  
  gzip on;
  gzip_disable msie6;
  gzip_comp_level 1;
  gzip_vary on;
  gzip_proxied expired no-cache no-store private;
  gzip_types text/plain text/xml text/javascript text/css application/json application/javascript application/x-javascript;
  
  server {
      listen 443 ssl;
      server_name domain.com;
      location / {
          proxy_pass http://127.0.0.1:3000/;
          proxy_http_version 1.1;
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header X-NginX-Proxy true;
          proxy_set_header Host $http_host;
          proxy_ssl_session_reuse off;
          proxy_cache_bypass $http_upgrade;
          proxy_redirect off;
      }
  }
  }
  
  

`

As I understand, I can't set gzip_static on; with the proxy_pass, so I should probably create a separate location that specifies the root path/to/static/files

Would be glad to all comments, thank you!
