FAQ
- What does TypeScript-first mean in Zod?
- Zod schemas produce static TypeScript types via z.infer(), eliminating the need to manually define interfaces. The runtime validation and compile-time types are always in sync, preventing type drift.
- How does Zod differ from Yup?
- Zod is TypeScript-first with automatic type inference, while Yup requires manual type definitions. Zod also supports more types (discriminated unions, records, maps, sets) and has better error customization with ZodError.
- Can Zod be used on both client and server?
- Yes. Zod is isomorphic and works in browsers, Node.js, Deno, and Bun. The same schema can validate form input on the client and API payloads on the server, ensuring end-to-end type safety.
