SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Zod provides runtime validation with static TypeScript inference, enabling safe parsing of untrusted data and robust error handling across applications.

Core Features & Use Cases

  • Schema definition and validation for primitives, objects, arrays, and unions
  • Type inference from schemas for strong TS types
  • JSON Schema generation and ecosystem integrations
  • Error customization, refinements, transforms, and codecs
  • Use cases: API validation, form validation, environment variable parsing, data parsing

Quick Start

Create a simple user schema and parse a sample input to demonstrate validation.

Frequently Asked Questions about zod

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I validate untrusted API data with TypeScript type inference?

You validate untrusted API data by defining schemas that execute runtime checks while automatically inferring static TypeScript types, ensuring parsed data conforms to expected structures.

What is the best way to parse environment variables using schema validation in TypeScript?

Schema validation for environment variable parsing allows you to declare expected primitive formats and execute runtime checks, safely transforming raw untrusted inputs into typed configuration objects.

Can I customize validation errors when parsing form input with Zod?

Yes, you can customize validation errors when parsing form input by applying a unified error map during schema declaration, allowing tailored error messages for failed runtime checks.

How do I execute asynchronous data validation for complex object schemas?

You execute asynchronous data validation by calling parseAsync on declared object schemas, performing runtime checks for complex structures and refinements on untrusted data inputs.

Does Zod support JSON Schema generation for ecosystem integrations?

Yes, Zod supports JSON Schema generation from declared schemas, facilitating ecosystem integrations by bridging TypeScript type inference with standard JSON validation formats.

When should I use safeParse instead of parse for runtime data validation?

Use safeParse instead of parse for runtime data validation when handling untrusted inputs that might fail, as safeParse catches validation errors gracefully without throwing exceptions.
