3.0 Support: “not?” about openapi-typescript HOT 3 CLOSED

It seems like this could be accomplished with a general union type which expresses all the basic types which openAPI supports, and the Exclude utility type:

type GenericTypes =
  | { [key: string]: unknown }
  | unknown[]
  | string
  | number
  | boolean;

type nonNumber = Exclude<GenericTypes, number>;

Of course the example in the docs cannot actually be statically narrowed at all, due to Typescript having no integer type 🙂

I actually haven’t used Exclude<> much! But it looks promising.

🤔 I think your solution is absolutely perfect for primitives. But my hesitation would be when it comes to advanced types. Like, what would not: { $ref: '…' } look like?

I haven’t run across not used in a real-world schema, and I couldn‘t get a good picture from the spec how this is enforced. Should we just put a pin in this until someone has a real-world example how they use it?

Good point(s). Waiting for a sample usecase sounds like a good plan to me 👍
