What is @firebase/messaging-types?

@firebase/messaging-types is a TypeScript type definition package for Firebase Cloud Messaging (FCM). It provides type definitions for the Firebase Messaging service, which allows you to send notifications and messages to users across different platforms such as web, iOS, and Android.

What are @firebase/messaging-types's main functionalities?

Requesting Permission

This feature allows you to request permission from the user to send notifications. The code sample demonstrates how to request notification permission using the Firebase Messaging service.

async function requestPermission() {
  try {
    await messaging.requestPermission();
    console.log('Notification permission granted.');
  } catch (error) {
    console.error('Unable to get permission to notify.', error);
  }
}

Getting Token

This feature allows you to retrieve the current registration token for the device. The token is used to uniquely identify the device for sending messages.

async function getToken() {
  try {
    const currentToken = await messaging.getToken();
    if (currentToken) {
      console.log('Token retrieved:', currentToken);
    } else {
      console.log('No registration token available. Request permission to generate one.');
    }
  } catch (error) {
    console.error('An error occurred while retrieving token.', error);
  }
}

Handling Messages

This feature allows you to handle incoming messages when the web app is in the foreground. The code sample demonstrates how to set up an event listener for incoming messages and display a notification.

messaging.onMessage((payload) => {
  console.log('Message received. ', payload);
  // Customize notification here
  const notificationTitle = 'Background Message Title';
  const notificationOptions = {
    body: 'Background Message body.',
    icon: '/firebase-logo.png'
  };

  return self.registration.showNotification(notificationTitle,
    notificationOptions);
});
