Get/Set extra-info with js-libjuju

Alright probably one for @hatch but who knows…

How do I get/set a models extra-info with js-libjuju?

Im trying to understand what the facades do with all their different versions etc, but I’m still a bit perplexed by them all…

Thanks

Tom

Ah the model-config facade seems to be what i’m after, finally found the API docs: https://github.com/juju/js-libjuju/tree/master/api
