I have a large web application that was built about 9-8 years ago with "pug" technology, and in recent years pages have been added in an innovative framework (vue.js) Now in any transition between an old page (pug) and a vue page, the Webpack (version 3.12) loads a build.js file (3.8MB!) that Located in index.html and takes an average of 9 seconds to load and significantly Interferes with the UX.

is there any way I can save the build.js in the cache? or alternatively, I would love to hear if anyone has another idea that can enhance the user experience

the webserver of the site is Nginx

edit: here is my nginx file (the relevant parts)

server {
    listen      80;
    server_name xxx.com;
    return 301 https://xxx$request_uri;
}

server {
    listen       443 ssl;
    server_name xxx.com;

    gzip on;
    gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
    gzip_min_length 1000;
      location ~ ^/dist/(?:ico|css|js|gif|jpe?g|png)$ {

    }

         try_files /lbo_builds/build_$1/public/$1/$2 =404;
    }

    location ~ ^/export/data/(.+)$ {
        gzip_static always;
        add_header Content-Encoding gzip;

    }

    location /customer_upload_document_proxy {
        proxy_set_header Cookie JSESSIONID=$cookie_jba_session;
        proxy_pass xxx;
    }

    location / {
        expires off;
        add_header Cache-Control "max-age=0, no-store, no-cache, must-revalidate";

        proxy_set_header X-Forwarded-For $remote_addr;

        proxy_pass http://$backend_upstream$request_uri;
    }
}
