@capacitor/push-notifications

The Push Notifications API provides access to native push notifications.

Install

npm install @capacitor/push-notifications
npx cap sync

iOS

On iOS you must enable the Push Notifications capability. See Setting Capabilities for instructions on how to enable the capability.

After enabling the Push Notifications capability, add the following to your app’s AppDelegate.swift:

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
  NotificationCenter.default.post(name: .capacitorDidRegisterForRemoteNotifications, object: deviceToken)
}

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
  NotificationCenter.default.post(name: .capacitorDidFailToRegisterForRemoteNotifications, object: error)
}

Android

The Push Notification API uses Firebase Cloud Messaging SDK for handling notifications. See Set up a Firebase Cloud Messaging client app on Android and follow the instructions for creating a Firebase project and registering your application. There is no need to add the Firebase SDK to your app or edit your app manifest - the Push Notifications provides that for you. All that is required is your Firebase project’s google-services.json file added to the module (app-level) directory of your app.

Variables

This plugin will use the following project variables (defined in your app’s variables.gradle file):

• $firebaseMessagingVersion version of com.google.firebase:firebase-messaging (default: 21.0.1)

Push Notifications icon

On Android, the Push Notifications icon with the appropriate name should be added to the AndroidManifest.xml file:

<meta-data android:name="com.google.firebase.messaging.default_notification_icon" android:resource="@mipmap/push_icon_name" />

If no icon is specified Android will use the application icon, but push icon should be white pixels on a transparent backdrop. As the application icon is not usually like that, it will show a white square or circle. So it’s recommended to provide the separate icon for Push Notifications.

Android Studio has an icon generator you can use to create your Push Notifications icon.

Push notifications appearance in foreground

{
  "plugins": {
    "PushNotifications": {
      "presentationOptions": ["badge", "sound", "alert"]
    }
  }
}

/// <reference types="@capacitor/push-notifications" />

import { CapacitorConfig } from '@capacitor/cli';

const config: CapacitorConfig = {
  plugins: {
    PushNotifications: {
      presentationOptions: ["badge", "sound", "alert"],
    },
  },
};

export default config;

Silent Push Notifications / Data-only Notifications

iOS

This plugin does not support iOS Silent Push (Remote Notifications). We recommend using native code solutions for handling these types of notifications, see Pushing Background Updates to Your App.

Android

This plugin does support data-only notifications, but will NOT call pushNotificationReceived if the app has been killed. To handle this scenario, you will need to create a service that extends FirebaseMessagingService, see Handling FCM Messages.

Common Issues

On Android, there are various system and app states that can affect the delivery of push notifications:

• If the device has entered Doze mode, your application may have restricted capabilities. To increase the chance of your notification being received, consider using FCM high priority messages.
• There are differences in behavior between development and production. Try testing your app outside of being launched by Android Studio. Read more here.

Example

import { PushNotifications } from '@capacitor/push-notifications';

const addListeners = async () => {
  await PushNotifications.addListener('registration', token => {
    console.info('Registration token: ', token.value);
  });

  await PushNotifications.addListener('registrationError', err => {
    console.error('Registration error: ', err.error);
  });

  await PushNotifications.addListener('pushNotificationReceived', notification => {
    console.log('Push notification received: ', notification);
  });

  await PushNotifications.addListener('pushNotificationActionPerformed', notification => {
    console.log('Push notification action performed', notification.actionId, notification.inputValue);
  });
}

const registerNotifications = async () => {
  let permStatus = await PushNotifications.checkPermissions();

  if (permStatus.receive === 'prompt') {
    permStatus = await PushNotifications.requestPermissions();
  }

  if (permStatus.receive !== 'granted') {
    throw new Error('User denied permissions!');
  }

  await PushNotifications.register();
}

const getDeliveredNotifications = async () => {
  const notificationList = await PushNotifications.getDeliveredNotifications();
  console.log('delivered notifications', notificationList);
}
