Hey there --
I've yet to settle on a good strategy for determining when a query returns zero results. Let's say I have a query called getSomeData -- Sometimes getSomeData is null when nothing comes back so I can use {{ getSomeData.data === null }} , but sometimes .data exists with all of the keys, it's just that all of the keys length are 0. So then I might try {{ getSomeData.data.id.length === 0 }} but that might not work if my first assumption is correct -- that .data is null -- in that case, you basically get an error since a reference to one of the keys is invalid (referring to a null object, hence no keys named anything). So then I get into some crazy thing that feels super hacky where I test for either condition.
My guess is that there's something much simpler that I'm missing.
