Introduction

Zod is a TypeScript-first validation library. Using Zod, you can define schemas you can use to validate data, from a simple string to a complex nested object.

import * as z from "zod";
 
const User = z.object({
  name: z.string(),
});
 
// some untrusted data...
const input = { /* stuff */ };
 
// the parsed result is validated and type safe!
const data = User.parse(input);
 
// so you can use it with confidence :)
console.log(data.name);
