`request.url` is 'https://localhost' with no port when https is enabled in framework mode

1. Clone https://github.com/phiggins/react-router-https-url-bug because apparently https does not work on StackBlitz
2. npm i && npm run dev
3. Access the site in a browser or via curl:

   $ curl --silent --cacert node_modules/.vite/basic-ssl/_cert.pem https://localhost:5173

Notes

I believe I fixed the root cause in node-fetch-server and this was released in version v0.13.0: https://github.com/remix-run/remix/releases/tag/node-fetch-server%400.13.0. However @timdorr indicated in #14010 that this would not be a simple upgrade:

Unfortunately, we're blocked on the fact that the newer version is ESM-only, which would require a breaking change to support: https://github.com/remix-run/remix/releases/tag/node-fetch-server%400.11.0

I'd be happy to add a workaround in react-router until the package upgrade can be done.

Yeah to clarify, we don't "pin" the version and have "@remix-run/node-fetch-server": "^0.9.0" in the package.json, but npm treats carets differently in 0.x release ranges so that explains why it's not picking up the 0.13.0 update.

You could fix this locally using an override:

"overrides": {
  "@remix-run/node-fetch-server": "0.13.0"
}

We might be able to use it if we use dynamic imports - I made this update in #14704 to see if CI raises any issues.

This appears to workaround the problem for me. Thank you! ✨

Fixed by #14704 and will be available in the next release
