"Connection" header overwritten by proxy for WS

[MilanKladivko]

Hello,

I've been trying out the proxy feature to allow seamless integration with my backend hosted locally.
Sadly, I cannot get WS connections to work. Using latest 0.19.0.

When using the proxy in ".nolluprc", the "Connection" header is rewritten from "upgrade" to "close", and my backend rejects it as a websocket protocol violation.
Direct connections do not have this issue.

I am not using HMR or other advanced features, just trying to host the frontend through nollup and not my backend directly...

{
    "contentBase": "./public",
    "proxy": {
        "/": "http://localhost:8100"
    }
}

Is there extra configuration required in ".nolluprc"? Should I look into express-http-proxy options to achieve this?

Nevermind, I guess it's not supported by the proxy lib. villadora/express-http-proxy#28

Feel free to close this, I'll just hack it into the frontend itself then.

This seems like a reasonable thing that should be supported. I'll have a look into it. :)

Hey, is there any update on this?
I would love to use websockets with this module.

No update on it. Been a very busy few months life-wise! 😅 Probably would have to replace express-http-proxy with something else or somehow manually take care of it. If anyone has additional information on this or suggestions for other proxies to use, happy to consider.
