Is Zod v4 tree-shakable?

Yes, Zod v4 includes a 'zod/mini' entry point which offers a functional, tree-shakable API designed specifically for performance-critical client-side applications.

Zod v4 is a TypeScript-first schema declaration and validation library that offers 14x faster parsing and 66% smaller bundle sizes compared to previous versions while maintaining full type safety.

Can I use Zod for frontend form validation?

Yes, Zod is highly effective for frontend forms, providing deep integration with libraries like React Hook Form to ensure form data matches your TypeScript types.

Does Zod support asynchronous validation?

Zod supports async refinements and transformations, as well as a dedicated implementAsync method for validating the inputs and outputs of asynchronous functions.

How does Zod handle validation errors?

Zod provides a detailed error object through its safeParse method, allowing developers to extract specific field errors, paths, and custom messages for user feedback.

API開発

Validates data at runtime with TypeScript-first schema definitions and static type inference.

概要

Zod v4 is a powerful validation library designed for TypeScript developers to bridge the gap between static types and runtime data. This skill enables Claude to efficiently implement complex data schemas, perform safe parsing with detailed error reporting, and transform data during validation. It covers advanced patterns like discriminated unions, recursive schemas, and file validation, making it indispensable for building robust APIs and type-safe frontend applications with high performance and minimal bundle sizes.
