SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill provides a comprehensive reference of Zod validation patterns to simplify building type-safe validators and deriving TypeScript types from schemas.

Core Features & Use Cases

  • Primitives, strings, numbers, booleans, dates, and more with chainable validations.
  • Object schemas with type inference, pretty error messaging, and utilities for partials, merges, discriminated unions, and transforms.
  • Real-world use: validate user input in forms or API payloads with typed results and robust error reporting.

Quick Start

To try, install zod in your project (npm install zod) and start composing schemas, for example z.object({ name: z.string(), age: z.number() }).

Frequently Asked Questions about zod-patterns

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

FAQPage Schema
How do I validate API payloads in TypeScript using Zod?

Validate API payloads in TypeScript using Zod by composing object schemas and utilizing safeParse to return typed results with robust error reporting. This skill provides patterns for handling API validation workflows with comprehensive error handling.

What is the best way to derive TypeScript types from Zod schemas?

Derive TypeScript types from Zod schemas using built-in type inference utilities like z.infer. This skill demonstrates how to define object schemas and automatically generate strong typings for runtime validation.

How do I handle complex form validation with Zod in TypeScript?

Handle complex form validation with Zod by composing primitives, objects, and unions, then applying transforms for user input. This skill covers real-world frontend patterns for validating forms with typed results.

Does Zod support branded types and discriminated unions?

Zod supports branded types and discriminated unions for enforcing best practices in type safety. This skill provides practical examples of composing schemas, merging objects, and handling partials.

Why should I use safeParse over parse for runtime validation?

Use safeParse over parse for runtime validation to gracefully handle invalid data without throwing exceptions. This skill enforces best practices by returning typed success or error objects for robust error reporting.

Can I transform data during Zod schema validation?

You can transform data during Zod schema validation using built-in transform functions within your object schemas. This skill provides patterns for chaining validations and modifying output types for API payloads.
