Trying to understand JSON…
(sopuli.xyz)
Meme transcription: Panel 1. Two images of JSON, one is the empty object, one is an object in which the key name maps to the value null. Caption: “Corporate needs you to find the difference between this picture and this picture”
Panel 2. The Java backend dev answers, “They’re the same picture.”
Except, if you use any library for deserialization of JSONs there is a chance that it will not distinguish between null and absent, and that will be absolutely standard compliant. This is also an issue with protobuf that inserts default values for plain types and enums. Those standards are just not fit too well for patching
I've never once seen a JSON serializer misjudge null and absent fields, I've just seen developers do that.
Well, Jackson before 2.9 did not differentiate, and although this was more than five years ago now, this is somewhat of a counter example
Also, you sound like serializers are not made by developers
Bruh, there's a difference between the one or two serializing packages used in each language, and the thousands and thousands and thousands of developers who miscode contracts after that point.
