Zod v3 Documentation
Zod is a TypeScript-first schema declaration and validation library designed to be developer-friendly. With Zod, you declare a validator once and Zod automatically infers the static TypeScript type. It eliminates duplicative type declarations and makes it easy to compose simpler types into complex data structures.
