Can I really type THAT in TypeScript!?
summary
Shows how to turn a runtime schema object into a precise TypeScript interface by building a generic define<T>(obj: T): T identity helper, extracting constructor return types with conditional types, mapping over properties to produce exact field types and using Pick/Omit/Partial/Required to mark some keys optional. Demonstrates examples (person schema -> Person interface, array-of-string aliases) and confirms the approach produces the expected types while noting small edge cases to handle.
