SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps developers implement robust data validation using Zod, addressing breaking changes from version 3 and providing patterns for common validation scenarios.

Core Features & Use Cases

  • Schema Definition: Define schemas for primitives, objects, arrays, unions, and more.
  • Type Inference: Generate TypeScript types directly from Zod schemas.
  • Validation & Parsing: Safely parse and validate incoming data against defined schemas.
  • Use Case: Ensure that user registration data conforms to specific formats (email, password strength, age limits) before it's processed by your application.

Quick Start

Use the zod-4 skill to define a schema for user data including email and password.

FAQPage Schema
How do I define a TypeScript validation schema for user registration data with Zod 4?

Define a Zod 4 validation schema for user registration by combining primitive types like email and string, then parse the input to ensure data conforms to specific formats and password strength before processing.

How do I handle breaking changes when migrating schema validation from Zod v3 to v4?

Handle Zod v3 to v4 breaking changes by updating your schema validation patterns for primitives, objects, arrays, and unions, ensuring your TypeScript type inference and parsing logic align with the new version specifications.

Can I use Zod 4 schema validation with React Hook Form for parsing form data?

Yes, you can integrate Zod 4 schema validation with React Hook Form to parse and validate form input, utilizing schema definitions and error handling strategies to ensure data conforms to your TypeScript types.

How does TypeScript type inference work with Zod 4 schema definitions?

TypeScript type inference with Zod 4 schema definitions works by automatically generating TypeScript interfaces directly from your defined validation schemas, ensuring your parsed data strictly matches the expected object and array structures.

What is the best way to apply transformations and refinements during Zod data parsing?

Apply transformations and refinements during Zod data parsing by chaining methods onto your schema definitions, allowing you to customize validation logic and modify output data for complex TypeScript application scenarios.

How do I validate arrays and unions using Zod 4 in TypeScript?

Validate arrays and unions in TypeScript using Zod 4 by defining schemas that specify acceptable object primitives and combined types, then parsing incoming data to ensure it safely conforms to the expected structures.
