email: string;
password: string;
confirmPassword: string;
name: string;
terms: boolean;
}
// components/LoginForm.tsx
import { useForm, SubmitHandler } from 'react-hook-form';
import { LoginFormData } from '../types/form';
const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
export const LoginForm: React.FC = () => {
const {
register,
handleSubmit,
// ... (see reference guides for full implementation)
