SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and assets (resource) components.

What problem does it solve?

Zod helps you prevent invalid data from entering your TypeScript app by enforcing schema validation at boundaries, producing actionable errors, and keeping types in sync with your runtime checks.

Core Features & Use Cases

  • Schema definition best practices: Use the right primitives, constrain strings, prefer enums, and avoid over-permissive schemas that “accept almost anything.”
  • Correct parsing and error handling: Use safeParse/safeParseAsync, validate early, collect all issues for better UX, and use parseAsync for async refinements.
  • Type safety and maintainability: Use z.infer, distinguish z.input vs output for transforms, and apply branded types and strict TypeScript settings to prevent subtle type bugs.

Quick Start

Apply the zod skill rules to your API request schema so invalid inputs fail fast with clear field-level error messages.

Frequently Asked Questions about zod

FAQPage Schema
How do I validate TypeScript API request schemas safely without throwing runtime errors?

Use Zod schema validation with safeParse to validate TypeScript API requests, which returns a structured result object containing success data or field-level errors instead of throwing exceptions.

What is the best way to handle async validations in a TypeScript schema?

Handle async validations in TypeScript schemas by using Zod's parseAsync and safeParseAsync methods, which properly execute asynchronous refinements during the data validation lifecycle.

How do I map and flatten validation errors to specific object fields in TypeScript?

Flatten Zod validation errors to map them to specific object fields by applying error flattening patterns, transforming nested issue paths into actionable field-level messages for frontend display.

Can I use z.infer and z.input to distinguish transformed types in TypeScript?

Use z.infer to extract the output type and z.input to extract the input type of transformed Zod schemas, ensuring TypeScript correctly distinguishes data shapes before and after validation.

How do I compose TypeScript schemas using extend, merge, pick, omit, and strict?

Compose TypeScript schemas by applying disciplined Zod schema composition methods like extend, merge, pick, omit, partial, and strict to build complex validation rules from reusable primitives.

When should I use safeParse instead of parse for backend request validation in TypeScript?

Use safeParse for backend request validation in TypeScript when you need to collect all schema validation issues gracefully, reserving parse for cases where throwing immediate exceptions is acceptable.
