Notification Hooks

React hooks for sending notifications through email, SMS, and push notification channels.

useNotification​

Send notifications with automatic loading states and error handling.

Send Email Notification​

import { useNotification } from '@ductape/react';

function WelcomeEmail({ userEmail, userName }: { userEmail: string; userName: string }) {
  const { mutate: sendNotification, isLoading, error } = useNotification({
    onSuccess: () => {
      alert('Welcome email sent!');
    }
  });

  const handleSend = () => {
    sendNotification({
      channel: 'email',
      to: userEmail,
      template: 'welcome-email',
      data: {
        name: userName,
        loginLink: 'https://app.com/login'
      }
    });
  };

  return (
    <button onClick={handleSend} disabled={isLoading}>
      {isLoading ? 'Sending...' : 'Send Welcome Email'}
    </button>
  );
}

Send SMS Notification​

function SendVerificationCode({ phoneNumber }: { phoneNumber: string }) {
  const [code] = useState(() => Math.floor(100000 + Math.random() * 900000).toString());

  const { mutate, isLoading } = useNotification({
    onSuccess: () => {
      alert('Verification code sent!');
    }
  });

  const handleSend = () => {
    mutate({
      channel: 'sms',
      to: phoneNumber,
      template: 'verification-code',
      data: {
        code,
        expiresIn: '10 minutes'
      }
    });
  };

  return (
    <button onClick={handleSend} disabled={isLoading}>
      {isLoading ? 'Sending...' : 'Send Code'}
    </button>
  );
}

Send Push Notification​

function SendPushNotification({ deviceToken, message }: { deviceToken: string; message: string }) {
  const { mutate, isLoading } = useNotification();

  const handleSend = () => {
    mutate({
      channel: 'push',
      to: deviceToken,
      data: {
        title: 'New Message',
        body: message,
        badge: 1,
        sound: 'default'
      }
    });
  };

  return (
    <button onClick={handleSend} disabled={isLoading}>
      Send Push
    </button>
  );
}

useNotificationBatch​

Send notifications to multiple recipients.

function BulkEmailSender() {
  const [recipients, setRecipients] = useState<string[]>([]);

  const { mutate: sendBatch, isLoading } = useNotificationBatch({
    onSuccess: (result) => {
      alert(`Sent ${result.successCount} emails successfully`);
    }
  });

  const handleSendAll = () => {
    sendBatch({
      channel: 'email',
      template: 'newsletter',
      recipients: recipients.map(email => ({
        to: email,
        data: {
          unsubscribeLink: `https://app.com/unsubscribe?email=${email}`
        }
      }))
    });
  };

  return (
    <div>
      <textarea
        placeholder="Enter emails (one per line)"
        onChange={(e) => setRecipients(e.target.value.split('\n').filter(Boolean))}
      />
      <button onClick={handleSendAll} disabled={isLoading || recipients.length === 0}>
        {isLoading ? `Sending to ${recipients.length} recipients...` : 'Send Newsletter'}
      </button>
    </div>
  );
}

useNotificationStatus​

Track notification delivery status.

function NotificationTracker({ notificationId }: { notificationId: string }) {
  const { data: status, isLoading } = useNotificationStatus(notificationId, {
    refetchInterval: 5000 // Poll every 5 seconds
  });

  if (isLoading) return <div>Loading status...</div>;

  return (
    <div className="notification-status">
      <h3>Notification Status</h3>
      <div>
        <span>Sent:</span> {status?.sent ? '✓' : '✗'}
      </div>
      <div>
        <span>Delivered:</span> {status?.delivered ? '✓' : '✗'}
      </div>
      <div>
        <span>Opened:</span> {status?.opened ? '✓' : '✗'}
      </div>
      <div>
        <span>Clicked:</span> {status?.clicked ? '✓' : '✗'}
      </div>
      {status?.deliveredAt && (
        <div>
          <span>Delivered at:</span> {new Date(status.deliveredAt).toLocaleString()}
        </div>
      )}
    </div>
  );
}
