Installation

Zod is available on npm and works in Node.js and all modern browsers. Install it using your preferred package manager.

npm

npm install zod

pnpm

pnpm install zod

yarn

yarn add zod

bun

bun add zod

JSR (Deno and other runtimes)

Zod is also available as @zod/zod on jsr.io :

deno add @zod/zod

Or import directly:

import * as z from "jsr:@zod/zod";

Requirements

Zod is tested against TypeScript v5.5 and later. Older versions may work but are not officially supported.

Enable strict Mode

You must enable strict mode in your tsconfig.json. This is a best practice for all TypeScript projects:

{
  "compilerOptions": {
    "strict": true
  }
}

Without strict mode, Zod’s type inference may not work correctly.

Bundle Size

Zod’s core bundle is just 2kb gzipped, making it ideal for both server and client-side applications.
