react-hook-form-zod

Build type-safe React forms by defining a Zod schema and connecting it to React Hook Form v7 using zodResolver. This approach uses z.infer to generate form types from the schema, ensuring your inputs and validation rules share a single source of truth.

Map server-side validation errors to React Hook Form fields by calling setError within your submit handler. This targets specific form fields with structured error messages returned from the server route, keeping client and server error handling consistent.

React Hook Form and Zod support multi-step flows and dynamic field arrays. The zodResolver integration maintains form state across steps while validating dynamic fields, making it suitable for registration or onboarding workflows.

You need @hookform/resolvers alongside react-hook-form and zod to bridge schema validation. The zodResolver function from this package integrates your Zod schema directly into the useForm configuration for client-side type checking.

Zod provides a single source of truth for form validation by defining schemas that generate both TypeScript types and runtime validation. This prevents drift between type definitions and validation logic, which is a common issue with custom rule implementations.

The setup handles client and server validation consistently by sharing Zod schemas across both environments. Client-side validation runs through zodResolver, while server-side errors map back to the same form fields using setError for unified error handling.
