A bit late in, so sorry for that, but FWIW, one can also use our async API
request wrapper for that, i.e. mark the function this is in as async and
then use something like:
let config = await Proxmox.Async.api2({
url: `/api2/extjs/nodes/${me.nodename}/qemu/${me.vmid}/config?current=1`
});
That would probably reduce the amount of changes required and also
keep the code a bit more linear.
Btw. don't we have the config available in some call-sites? I.e., would
it make sense to allow overriding it already now? Because if we can
reduce the need for an extra API call due to information being already
available then I'd always favor that, having experienced working over
some high latency links and/or spotty & congested (wifi) connections.
We can improve this later on, but would be good to evaluate the status
quo already; FWIW I'd be open to look into querying the respective
properties in the cluster resource API endpoint, which would then be
available in the in-memory resource store and really cheap to query
from the frontend. As we already get some properties the backend side
would not really get more expensive either. Again, that does not has
to be a prerequisite for applying something like this, but IMO worth
to evaluate at some (soonish) point.
