How does this skill help with form validation?

It provides patterns for using Zod with form libraries like React Hook Form and includes methods like error.flatten() to easily map validation errors back to specific UI fields.

Does this skill support asynchronous validation?

Yes, it includes implementation patterns for parseAsync and safeParseAsync to handle complex refinements and transformations that require external lookups or database calls.

Can I use this for both frontend and backend projects?

Absolutely. Zod is a zero-dependency, lightweight library that works seamlessly in Node.js environments, modern browsers, and edge runtimes.

What makes Zod different from standard TypeScript interfaces?

Unlike interfaces which are removed at compile time, Zod schemas provide runtime validation while automatically generating TypeScript types through inference, ensuring your data matches your types at all times.

Desarrollo de API

Implements TypeScript-first schema declaration and validation patterns to ensure runtime type safety and robust data parsing.

Acerca de

This skill equips Claude with the expertise to implement Zod, the premier TypeScript-first schema validation library. It enables the creation of type-safe schemas for API request validation, form handling, and configuration parsing, effectively bridging the gap between static types and runtime data. By leveraging Zod's powerful inference capabilities, it helps developers eliminate redundant type declarations while providing comprehensive error handling and data transformation patterns. It is essential for any modern TypeScript project requiring strict data integrity at the boundaries of the application.
