FAQ

Json To Ts Interface questions

?Why might a generated array type miss some values?

The generator inspects up to the first twelve array items. Later items may contain shapes or types that are absent from the generated interface.

?Does the generated interface validate incoming JSON at runtime?

No. TypeScript interfaces describe compile-time types. Add runtime validation separately, and review optional fields and repeated nested type names.
