Is it possible for Nginx to control file sharing?

Question

Nginx

There is a server on NodeJS, one of the functions of which is to give files. There is a problem when downloading from remote locations with a bad link. For users, the file is downloaded, but not finalized by the browser.
As a solution, I came up with using Nginx, but now the file just hangs in a constant download.
How to properly configure it to distribute files?

Answer 1

if it's just about setting up nginx as a reverse proxy, here's an example
(there is an audio folder inside the application folder, which we want to give through nginx)

server {
server_name example.com;

    location /audio/ {
       root /path/to/appfolder;
     }

    location / {

        proxy_pass http://localhost:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;

    }
}
