What is the usage of nodejs inside fhem container, instead of using nodejs in a separate container, can you explain your usecase more detailed?

[volschin]

I‘m using the echo module. This is probably to tightly integrated to be run in a separate container. If you see a way to do so, I‘m open to a suggestion.

My alexa-fhem and homebridges are run in a different container.

The latest bullseye image ghcr.io/fhem/fhem-docker:dev-bullseye contains nodejs 18, so this issue may probably be closed.
