please provide any errors you are getting

Hi @Brody, nevermind. I got mixed up between the native fetch() function and the one that is provided by node-fetch npm package.
This post gave me the clue: https://stackoverflow.com/a/74611064

So you where able to successfully download the file over the private network?

Yes, it works really well.

In case anyone would like to use the same approach here's the code snippet for express/nodejs:

            const url = 'http://xxxxx.railway.internal:3000/api/public/dl/C_izechY/data/xxxx.zip'; // This is the URL of a file hosted on Railway internal network using Filebrowser template (make sure to share the file first and set long expiry date)
            const response = await fetch(url);

            if (!response.ok) {
                res.sendStatus(500);
                return;
            }

            // Set headers
            res.setHeader('Content-Type', response.headers.get('Content-Type'));
            res.setHeader('Content-Length', response.headers.get('Content-Length'));
            res.setHeader('Content-Disposition', 'attachment; filename=xxxx.zip'); // replace with your desired filename

            // Pipe the response stream directly to res
            response.body.pipe(res);

Above code lets your server fetches the file from other service in the same project via Railway's private network.
You can also install npm package such as express-rate-limit to prevent anyone from abusing the download endpoint (so not to let them waste your egress bills, just make sure to setup x-forwarded-for header config properly on the limiter)

Using this approach, the file can only be downloaded via endpoint that you can control.

It is not maybe state-of-the-art solution but it works for my use-case for now.

i might even go as far as to turn [http://xxxxx.railway.internal:3000/api/public/dl/C_izechY/data/xxxx.zip](http://xxxxx.railway.internal:3000/api/public/dl/C_izechY/data/xxxx.zip) into an environment variable like DOWNLOAD_URL just in case you need to change it then you wont have to edit code

oh true, that's a neat approach. I'll do that. so at least whenever i need to change something, I don't have to push any changes in the code

👍

exactly

Thank you Brody!

no problem!
