What problem does it solve?
React Hook Form (RHF) prevents slow, bug-prone form state management by keeping inputs mostly uncontrolled, validating via a single schema source, and cleanly handling server-side errors—so your EOS SaaS forms don’t desync or re-render excessively.
Core Features & Use Cases
- Uncontrolled-first form performance: Use
register for native inputs to avoid re-rendering on every keystroke, and use Controller only when refs aren’t available.
- Schema-driven validation with Zod: Integrate
zodResolver so the same rules produce consistent client validation and user-facing error messages.
- Dynamic arrays and server error injection: Use
useFieldArray for repeatable rows (with stable field.id keys) and setError / clearErrors to map API validation back onto the right fields.
Quick Start
Use react_hook_form to create a Zod-validated shadcn <Form> that submits via a React Query mutation and shows both client and server field errors correctly.
