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.”
That’s interesting. I’m on the opposite team. If a customer model defines an optional birthday, for instance, I’d rather have it serialized as a null value if it’s not available for a specific customer.
The biggest reason for me is that it’s less data to send over a network. Especially when I’m working with lists of objects, including null fields can add a noticeable chunk to the payload.
There are some cases where it might be worth it to differentiate “No value” and “No attribute”, but in most cases they can be treated the same, since the data should really be validated against a schema anyway.
Depends on the application. When the user is able to set the schema via database, then you cannot assume the shape of the data.
I’m not sure I understand what you mean.
Yeah, nevermind, I didn’t know what I wrote either. I need my sleep lol.
