@capacitor-firebase/messaging

⚡️ Capacitor plugin for Firebase Cloud Messaging (FCM).

Installation

npm install @capacitor-firebase/messaging firebase
npx cap sync

Add Firebase to your project if you haven't already (Android / iOS / Web).

Android

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: 20.0.6)

Push Notification Icon

The Push Notification icon with the appropriate name should be added to the android/app/src/main/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 uses the application icon, but the push icon should be white pixels on a transparent background. Since the application icon does not usually look like this, it shows a white square or circle. Therefore, it is recommended to provide a separate icon for push notifications.

Prevent auto initialization

When a registration token is generated, the library uploads the identifier and configuration data to Firebase. If you prefer to prevent token autogeneration, disable Analytics collection and FCM auto initialization by adding these metadata values to the android/app/src/main/AndroidManifest.xml file:

<meta-data
    android:name="firebase_messaging_auto_init_enabled"
    android:value="false" />
<meta-data
    android:name="firebase_analytics_collection_enabled"
    android:value="false" />

iOS

See Prerequisites and complete the prerequisites first.

See Upload the APNS Certificate or Key to Firebase and follow the instructions to upload the APNS Certificate or APNS Auth Key to Firebase.

If you have difficulties with the instructions, you can also look at the corresponding sections of this guide. The steps are explained there in a quite understandable way. But be aware that this guide is more detailed and covers more than you need. Use it only for assistance.

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)
}
    
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    NotificationCenter.default.post(name: Notification.Name.init("didReceiveRemoteNotification"), object: completionHandler, userInfo: userInfo)
}

Finally edit your ios/App/App/Info.plist and set FirebaseAppDelegateProxyEnabled key to NO.

Attention: If you use this plugin in combination with @capacitor-firebase/authentication, then add the following to your app's AppDelegate.swift:

+ import FirebaseAuth

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
+    if Auth.auth().canHandle(url) {
+      return true
+    }
    return ApplicationDelegateProxy.shared.application(app, open: url, options: options)
}

Prevent auto initialization

When a registration token is generated, the library uploads the identifier and configuration data to Firebase. If you prefer to prevent token autogeneration, disable FCM auto initialization by editing your ios/App/App/Info.plist and set FirebaseMessagingAutoInitEnabled key to NO.

Web

  1. See Configure Web Credentials with FCM and follow the instructions to configure your web credentials correctly.
  2. Add a firebase-messaging-sw.js file to the root of your domain. This file can be empty if you do not want to receive push notifications in the background. See Setting notification options in the service worker for more information.

Configuration

On iOS you can configure the way the push notifications are displayed when the app is in foreground.

Prop Type Description Default Since
presentationOptions PresentationOption[] 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. Only available for iOS. ["badge", "sound", "alert"] 0.2.2

Examples

In capacitor.config.json:

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

In capacitor.config.ts:

/// <reference types="@capacitor/firebase-messaging" />

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

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

export default config;
