zod-mocking: Generate mock data from your Zod schemas. zod-fixture: Use your zod schemas to automate the generation of non-relevant test fixtures in a deterministic way.

6 days ago · Zod 4 will remain in beta for roughly 6 weeks as I work with library authors and major adopters to ensure a smooth day-one transition from Zod 3 to Zod 4. I encourage all users of …

Zod는 개발자 친화적으로 설계되었습니다. 목표는 중복된 타입 선언을 없애는 것입니다. Zod를 사용하면 검증기를 한 번만 선언하면, Zod가 자동으로 정적 TypeScript 타입을 추론합니다. 간단한 타입을 복잡한 데이터 구조로 합성하기도 쉽습니다.

It's a much simpler approach that lets you reuse a function type declaration without repeating yourself (namely, copy-pasting a bunch of ow assertions at the beginning of every function). Also Zod lets you validate your return types as well, so you can be sure there won't be any unexpected data passed downstream. <br/> ## Changelog

Zod 是一个 TypeScript 优先的模式声明和验证库。 我使用术语 "模式" 来广义地指任何数据类型，从简单的 字符串 到复杂的嵌套对象。

New — Zod 4 introduces a new feature: native JSON Schema conversion. JSON Schema is a standard for describing the structure of JSON (with JSON). It's widely used in OpenAPI definitions and defining structured outputs for AI. To convert a Zod schema to JSON Schema, use the z.toJSONSchema () function.

For convenience, Zod provides a global registry (z.globalRegistry) that can be used to store metadata for JSON Schema generation or other purposes. It accepts the following metadata:

The @zod/core package implements the parsers and utilities that are shared by zod and @zod/mini. It is not intended to be used directly; instead it's designed to be extended by other packages.

This page will walk you through the basics of creating schemas, parsing data, and using inferred types. For complete documentation on Zod's schema API, refer to Defining schemas.

Error messages in Zod are generated by passing metadata about a validation issue through a chain of error maps. Error maps with higher priority override messages generated by maps …
