# Introduction to Zod - TypeScript Schema Validation

Zod TypeScript-first schema validation with static type inference by @colinhacks Website • Discord • 𝕏 • Bluesky Zod 4 is stable. Read the release notes and migration guide . 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); Features Zero external dependencies Works in Node.js and all modern browsers Tiny: 2kb core bundle (gzipped) Immutable API: methods return a new instance Concise interface Works with TypeScript and plain JS Built-in JSON Schema conversion Extensive ecosystem Installation npm install zod Zod is also available as @zod/zod on jsr.io . Zod provides an MCP server that can be used by agents to search Zod's docs. To add to your editor, follow these instructions . Zod also provides an llms.txt file. Requirements Zod is tested against TypeScript v5.5 and later. Older versions may work but are not officially supported. "strict" You must enable strict mode in your tsconfig.json . This is a best practice for all TypeScript projects. // tsconfig.json { // ... "compilerOptions" : { // ... "strict" : true } } Ecosystem Zod has a thriving ecosystem of libraries, tools, and integrations. Refer to the Ecosystem page for a complete list of libraries that support Zod or are built on top of it. Resources API Libraries Form Integrations Zod to X X to Zod Mocking Libraries Powered by Zod I also contribute to the following projects, which I'd like to highlight: tRPC - End-to-end typesafe APIs, with support for Zod schemas React Hook Form - Hook-based form validation with a Zod resolver zshy - Originally created as Zod's internal build tool. Bundler-free, batteries-included build tool for TypeScript libraries. Powered by tsc . Sponsors Sponsorship at any level is appreciated and encouraged.
