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.”
I wasn’t taking about new fields. I was talking about resource partial updates (eg PATCH, or commonly the U in CRUD).
If you just want to update a single field on a resource with 100 fields, rather than GETting the entire resource, updating the single field, and PUTting whole thing back, just do a PATCH with the single field.
Likewise if you’re POSTing a resource that has nullable fields, but the default value isn’t null, how do you indicate that you want the default value for a given field? Do you have to first query some metadata API? That doesn’t seem ideal, when this existing pattern exists
You are not logged in. However you can subscribe from another Fediverse account, for example Lemmy or Mastodon. To do this, paste the following into the search field of your instance: !programmerhumor@lemmy.ml
Post funny things about programming here! (Or just rant about your favourite programming language.)
Rules:
Posts must be relevant to programming, programmers, or computer science.
No NSFW content.
Jokes must be in good taste. No hate speech, bigotry, etc.
For an API there should always be a version parameter/endpoint, imho.
Edit for further context: Ideally, a parameter.

Those are two very fair points - I agree.
