What problem does it solve?

Zod provides a TypeScript-first approach to define runtime schemas for validating data and inferring types, addressing the gap between runtime input and static TypeScript types across APIs, forms, and data processing.

Core Features & Use Cases

  • Type-safe runtime validation with schemas defined via z.object, z.string, z.number, and other helpers.
  • Type inference via z.infer to derive TypeScript types from schemas.
  • Flexible parsing options: .parse (throws), .safeParse (returns result), and .parseAsync for async validation.
  • JSON Schema generation via z.toJSONSchema for OpenAPI/AI tooling, plus metadata support with .meta().
  • Codecs for bidirectional transformations and advanced patterns like recursion and lazy types.
  • Use cases include API input validation, form validation, data ingestion pipelines, and contract-driven development.

Quick Start

Define a simple user schema with z.object and validate data using safeParse.

FAQPage Schema
How do I validate runtime data against TypeScript types?

Zod schemas provide type-safe runtime validation by defining structures with z.object and deriving static types via z.infer. This ensures untrusted input matches your TypeScript definitions before processing.

What is the difference between parse and safeParse for API validation?

For API validation, .parse throws an error on invalid data, while .safeParse returns a structured result object containing success status and error details. Use .parseAsync for asynchronous validation refinements.

Can I generate JSON Schema from TypeScript types for OpenAPI documentation?

Yes, you can generate JSON Schema from TypeScript types using z.toJSONSchema. This produces standard schemas suitable for OpenAPI documentation and AI tooling integration, with additional metadata support via .meta().

Does Zod support async validation and complex recursive schemas?

Zod supports async validation through .parseAsync and handles complex patterns using recursion and lazy types. It also includes codecs for bidirectional transformations within robust data validation workflows.

What are the best runtime validation libraries for TypeScript form handling?

TypeScript-first runtime validation libraries like Zod are ideal for form handling because they define schemas using z.string and z.number, ensuring input matches static types while providing flexible parsing options.
