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.”
They’re semantically different for PATCH requests. The first does nothing, the second should unset the
name
field.Only if using JSON merge patch, and that’s the only time it’s acceptable. But JSON patch should be preferred over JSON merge patch anyway.
Servers should accept both null and undefined for normal request bodies, and clients should treat both as the same in responses. API designers should not give each bespoke semantics.
JSON patch is a dangerous thing to use over a network. It will allow you to change things inside array indices without knowing whether the same thing is still at that index by the time the server processes your request. That’s a recipe for race conditions.
That’s what the If-Match header is for. It prevents this problem.
That being said, I generally think
PUT
s are preferable toPATCH
es for simplicity.Why?
Because Java struggles with basic things?
It’s absurd to send that much data on every patch request, to express no more information, but just to appease the shittiness of Java.
Why are you so ignorant?
Why not explaining instead of looking down on people? Now they know they’re wrong bit don’t know why. Nice.
You’ve replied to the wrong person.
