Zod Validation Patterns

Core Concepts

Zod provides runtime validation with automatic TypeScript type inference — define the schema once, get the type for free:

import { z } from "zod";

const UserSchema = z.object({
    id: z.string().uuid(),
    name: z.string().min(1),
    email: z.string().email(),
    role: z.enum(["admin", "member", "viewer"]),
    createdAt: z.coerce.date(),
});

type User = z.infer<typeof UserSchema>;
