Type-Safe Accessible Form Engine with Zod & React Hook Form
Generates accessible, type-safe multi-field form components with asynchronous validation, field arrays, and WCAG AA compliance.
Customize Placeholders in Real-Time
Customize the list of form fields and validation rules to match your onboarding or checkout flow.
Write a production-grade, accessible form component in React and TypeScript using 'react-hook-form' and '@hookform/resolvers/zod'. Form requirements: 1. Fields: Name, Email (with async domain check), Password (with live strength meter scoring 4 criteria), Country Select, Terms Checkbox, and Dynamic Tag Array (add/remove items). 2. Zod Schema: Strict types, custom regex patterns, and descriptive error messages for every failure state. 3. Accessibility: - Proper 'aria-invalid', 'aria-describedby', and 'role="alert"' linkages for error states. - Screen-reader announceable validation feedback. - High-contrast visible focus rings conforming to WCAG 2.1 AA. 4. State Handling: Disabled submit button while isSubmitting or isValidating, inline spinner, server-side error mapping, and form reset on success. 5. Unit Test: Vitest / React Testing Library test suite validating error triggers on empty submit and happy-path submission.
Optimization Tips & Parameters
Use aria-describedby pointing to error IDs to ensure blind and low-vision users receive error notices immediately.
