Zod is a TypeScript-first schema declaration and validation library. It lets you define schemas that validate data at runtime while providing TypeScript types at compile time.

Does it generate nested schemas?

Yes! Nested objects generate nested z.object() schemas, and arrays generate z.array() schemas with the correct inner type.

Can I use the output directly in my project?

Yes, the generated code is valid Zod schema code that you can paste directly into your TypeScript project. Just make sure you have the 'zod' package installed.

Does it handle null values?

Yes, null values generate z.null() schemas, and fields that could be null use z.nullable().
