@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.

Android 13 requires a permission check in order to receive push notifications. You are required to call checkPermissions() and requestPermissions() accordingly, when targeting SDK 33.

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: 23.3.1)

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 Notification channel​

From Android 8.0 (API level 26) and higher, notification channels are supported and recommended. The SDK will derive the channelId for incoming push notifications in the following order:

  1. Firstly it will check if the incoming notification has a channelId set. When sending a push notification from either the FCM dashboard, or through their API, it's possible to specify a channelId.
  2. Then it will check for a possible given value in the AndroidManifest.xml. If you prefer to create and use your own default channel, set default_notification_channel_id to the ID of your notification channel object as shown; FCM will use this value whenever incoming messages do not explicitly set a notification channel.
<meta-data
    android:name="com.google.firebase.messaging.default_notification_channel_id"
    android:value="@string/default_notification_channel_id" />
  1. Lastly it will use the fallback channelId that the Firebase SDK provides for us. FCM provides a default notification channel with basic settings out of the box. This channel will be created by the Firebase SDK upon receiving the first push message.

Warning When using option 1 or 2, you are still required to create a notification channel in code with an ID that matches the one used the chosen option. You can use createChannel(...) for this. If you don't do this, the SDK will fallback to option 3.

Push notifications appearance in foreground​

You can configure the way the push notifications are displayed when the app is in foreground.

PropTypeDescriptionSince
presentationOptionsPresentationOption[]This is an array of strings you can combine. Possible values in the array are: - badge: badge count on the app icon is updated (default value) - sound: the device will ring/vibrate when the push notification is received - alert: the push notification is displayed in a native dialog An empty array can be provided if none of the options are desired. badge is only available for iOS.1.0.0

Examples​

In capacitor.config.json:

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

In capacitor.config.ts:

/// <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);
}

API​

register()​

register() => Promise<void>

Register the app to receive push notifications.

This method will trigger the 'registration' event with the push token or 'registrationError' if there was a problem. It does not prompt the user for notification permissions, use requestPermissions() first.

unregister()​

unregister() => Promise<void>

Unregister the app from push notifications.

This will delete a firebase token on Android, and unregister APNS on iOS.

Since: 5.0.0

getDeliveredNotifications()​

getDeliveredNotifications() => Promise<DeliveredNotifications>

Get a list of notifications that are visible on the notifications screen.

Returns: Promise<DeliveredNotifications>

Remove the specified notifications from the notifications screen.

ParamType
deliveredDeliveredNotifications

Since: 1.0.0

removeAllDeliveredNotifications()​

removeAllDeliveredNotifications() => Promise<void>

Remove all the notifications from the notifications screen.
