Frequently Asked Questions

What is Zod?

Zod is a TypeScript-first schema validation library. It lets you define schemas that validate data at runtime while providing full TypeScript type inference. It's used with tRPC, React Hook Form, Next.js Server Actions, and more.

Does the output include TypeScript types?

Yes. The generated code includes both the Zod schema and a TypeScript type derived from it using z.infer<typeof Schema>. You get runtime validation and compile-time types from a single source of truth.

Can I use the output directly in my project?

Yes. The output is valid TypeScript that imports from 'zod'. Just install zod (npm install zod) and paste the generated code into your project.
