import { useRapidForm } from 'rapid-form';

export function ContactForm() {
  const { refValidation, errors, values } = useRapidForm();

  return (
    <form ref={(ref) => refValidation(ref)}>
      <input name="email" type="email" required placeholder="you@example.com" />
      {errors.email?.isInvalid && (
        <span>{errors.email.message}</span>
      )}

      <input name="name" required placeholder="Your name" />
      {errors.name?.isInvalid && <span>{errors.name.message}</span>}

      <button type="submit">Send</button>
    </form>
  );
}

That’s the whole thing. No schema. No register(). No Controller. Just native HTML.

Why Rapid Form?

~2KB

Zero runtime dependencies. Ships in under 2KB minified and gzipped. react-hook-form is ~25KB. Your users will notice.

Native HTML

Any element with name + required is automatically validated. No register(). No Controller. No wrappers.

No re-renders

Validation is event-driven, not controlled. Your form doesn’t re-render on every keystroke. It stays fast.

Any field type

input, select, textarea, checkbox — all supported out of the box. If the browser knows it, Rapid Form handles it.
