Which env variable do I change for the development websocket?

[worldly cliff]

I am running remix in dev mode inside of a docker container and also another one outside. I need to set a port for the websocket so that auto refresh works. I am able to forward a port in de docker config. but I also want to hardcode the port in the config

Are you looking for this?

instead of hard coding the value you can probably use some env variable as well process.env.DEV_SERVER_PORT

REMIX_DEV_SERVER_WS_PORT https://github.com/remix-run/remix/blob/main/packages/remix-dev/config.ts#L397-L402
