Firebase get length of object / number of children in object

Is there a way to get the number of children of an object without downloading the entire object? From what I understand using numChildren would first download the entire object, would it not?

Yes, currently it would. Getting the number of children without downloading the entire object is currently not possible (though it may be a feature added in the future).

As a work-around, you may try storing the length in a separate location in Firebase (and update its value whenever children are added or removed).
