React Hook Form

Build fast, uncontrolled forms with React Hook Form. Wires register and useForm, integrates Zod/Yup schema validation via resolvers, handles field arrays, dependent fields, and async submission with minimal re-renders.

This skill helps you implement performant forms with React Hook Form. It sets up useForm with register or Controller for UI libraries, adds schema validation through @hookform/resolvers (Zod, Yup, Valibot), manages dynamic field arrays with useFieldArray, handles cross-field and async validation, surfaces errors accessibly, and keeps re-renders minimal via its uncontrolled architecture.

When to use

Use when building forms in React — sign-up and checkout flows, dynamic field arrays, wizard steps, or forms with schema-based validation — that need strong performance and clean error handling.

Examples

Form with Zod validation

Schema-validated sign-up form

Build a React Hook Form sign-up form validated with a Zod schema via zodResolver, showing accessible field errors and disabling submit while pending

Dynamic field array

Add/remove repeatable rows

Use React Hook Form useFieldArray to build an invoice form where the user can add and remove line-item rows, each with validated quantity and price
