@ghaiklor sadlly, I didn't find a perfect solution yet. Naive solution would indeed pass most cases but the Partial<Model> one. see type-challenges/type-challenges#19507

from type-challenges-solutions.

This doesn't work for such cases

Expect<Equal<ObjectEntries<{ key: 1 | undefined }>, ['key', 1 | undefined]>>,
Expect<Equal<ObjectEntries<{ key?: 1 | undefined }>, ['key', 1 | undefined]>>,

@zhaoyao91 did you manage to improve the solution to get those tests passing?

from type-challenges-solutions.

This is my solution so far

type ObjectEntries<
  T extends Record<keyof any, any>,
  K extends keyof T = keyof T
> = K extends any
  ? [K, Required<T>[K] extends never ? undefined : Required<T>[K]]
  : never;
