Zod Overview

Zod is a TypeScript-first schema validation library.

Why Zod?

• ✅ TypeScript type inference
• ✅ Runtime validation
• ✅ Zero dependencies
• ✅ Works in Node.js and browsers

Quick Start

import { z } from 'zod';

// Define a schema
const UserSchema = z.object({
  name: z.string(),
  age: z.number().min(0),
  email: z.string().email(),
});

// Parse data
const user = UserSchema.parse({
  name: "John",
  age: 30,
  email: "john@example.com"
});

// Type is inferred!
type User = z.infer<typeof UserSchema>;
