import { useWaitlist } from "@wacht/nextjs";

function WaitlistPage() {
  const { loading, joinWaitlist } = useWaitlist();
  const [joined, setJoined] = useState(false);
  const [error, setError] = useState<string | null>(null);

  const handleSubmit = async (firstName: string, lastName: string, email: string) => {
    setError(null);
    const result = await joinWaitlist({ first_name: firstName, last_name: lastName, email });

    if (result.data) {
      setJoined(true);
    } else if (result.error) {
      setError(result.error.message);
    }
  };

  if (joined) {
    return <p>You're on the waitlist! We'll notify you at signup.</p>;
  }

  return (
    <form onSubmit={handleSubmit}>
      {error && <p className="error">{error}</p>}
      {/* Form fields */}
    </form>
  );
}
