How does the skill handle complex validation logic?

It provides patterns for using .refine() for simple checks and .superRefine() for more complex, multi-field validations and custom issue reporting.

What are the major syntax changes in Zod 4?

Zod 4 promotes top-level validators like z.email() and z.uuid() instead of chaining them, and uses a unified 'error' parameter for custom error messages.

Does this skill help with form validation?

Yes, it provides specific implementation patterns for React Hook Form using the zodResolver to ensure client-side type safety.

Can Zod 4 handle data type conversion?

Yes, it includes built-in support for coercion using z.coerce, which allows you to automatically convert inputs like strings to numbers or dates.

Desarrollo de API

Streamlines the creation, migration, and implementation of Zod version 4 schemas for robust TypeScript data validation.

Acerca de

The Zod 4 skill provides specialized guidance for developers using the TypeScript-first schema declaration and validation library. It helps bridge the gap between Zod 3 and 4 by identifying breaking changes, implementing complex object schemas, and configuring advanced features like discriminated unions and transformations. Whether you are building API request adapters, environment variable validators, or client-side forms, this skill ensures your data parsing is type-safe, performant, and follows the latest Zod 4 best practices.
