BREAKING CHANGE: Serialization of the empty string is now treated as
undefinedinstead of an UnserializableParamError.Otherwise, the serialization of
{ foo: null }would conflict with{ foo: '' }.This serializer chooses to support the more common and more useful case of sending
nullas a meaningful value while treating the empty string as sending no value.
This aligns with common UX patterns where input fields are initialized to the empty string.
Closes #20.
