Extremely easy plug&play push notification plugin for Cordova applications with Google Firebase FCM.
FCMPlugin.createNotificationChannelAndroid improved, now accepting three other options: "sound", "lights" and "vibration", like in:
FCMPlugin.createNotificationChannelAndroid({
id: "urgent_alert", // required
name: "Urgent Alert", // required
description: "Very urgent message alert",
importance: "high", // https://developer.android.com/guide/topics/ui/notifiers/notifications#importance
visibility: "public", // https://developer.android.com/training/notify-user/build-notification#lockscreenNotification
sound: "alert_sound", // In the "alert_sound" example, the file should located as resources/raw/alert_sound.mp3
lights: true, // enable lights for notifications
vibration: true // enable vibration for notifications
});IOS 9 support reintroduced.
For Android, some notification properties are only defined programmatically, one of those is channel. Channel can define the default behavior for notifications on Android 8.0+. This feature was meant to bring the channel-only configurations importance and visibility:
FCMPlugin.createNotificationChannelAndroid({
id: "urgent_alert", // required
name: "Urgent Alert", // required
description: "Very urgent message alert",
importance: "high", // https://developer.android.com/guide/topics/ui/notifiers/notifications#importance
visibility: "public", // https://developer.android.com/training/notify-user/build-notification#lockscreenNotification
});To have a notification to use the channel, you have to add to the push notification payload the key android_channel_id with the id given to createNotificationChannelAndroid (https://firebase.google.com/docs/cloud-messaging/http-server-ref#notification-payload-support)
As a hotfix to avoid incompatibility with cordova-plugin-ionic-webview, the the changes requested for cordova support (https://cordova.apache.org/howto/2020/03/18/wkwebviewonly) will not be automatic applied.
On iOS, first run doesn't automatically request Push permission.
The permission, as it is still required, may now be requested from javascript at any moment by executing:
//FCMPlugin.requestPushPermissionIOS( successCallback(), errorCallback(err) );
FCMPlugin.requestPushPermissionIOS();Replaced UIWebView with WKWebView, as required by Apple (https://developer.apple.com/documentation/uikit/uiwebview).
For a smooth upgrade, the changes requested for cordova support (https://cordova.apache.org/howto/2020/03/18/wkwebviewonly) are applied automatically.
For both platforms:
- Not only copies, from application root, the Google Services configuration files on build, but also on install;
onFirebaseDataNotificationIOSremoved, as relied on upstream socket connection, which will is deprecated and will be removed in Firebase 7 (https://firebase.google.com/support/release-notes/ios#fcm, announced in February 25, 2020).
For iOS:
- On install "Remote Notification" is set as a "Background Mode" capacity automatically;
- Firebase now is handled manually, due to complications of auto-swizzling;
- Firebase dependencies are now set to 6.21.0;
- Delayed Firebase registration, by 300ms, to avoid deadlock issue with Watchdog;
- Removed support for iOS 9.
For Android:
- Demonstrative code, for custom notifications, was removed and its imports of androidx classes to improve compatibility with older cordova plugins.
For the IOS, if app is on the foreground and the app receives a data push notification, the data can be retrieved by setting the callback to the new method: FCMPlugin.onFirebaseDataNotificationIOS [Deprecated].
FCMPlugin.onFirebaseDataNotificationIOS(
function(payload) {
console.info("Message id: "+payload.messageID)
console.info("Data parameters: "+payload.appData)
}
);This method is specifically implemented on IOS due to specific payload format (src/FCMPlugin.d.ts).
Due to a bug introduced in v4.4.3, the file platforms/android/app/src/main/res/values/strings.xml had two tags included on install, tags which, on build, are also included by [email protected]. Hence failing the build process.
To apply the fix, install the new version and remove these two tags from your values/strings.xml:
<string name="google_app_id">...</string><string name="google_api_key">...</string>
ANDROID_DEFAULT_NOTIFICATION_ICON included as a variable.
To define the default icon for notifications (com.google.firebase.messaging.default_notification_icon), install this plugin like:
cordova plugin add cordova-plugin-fcm-with-dependecy-updated --variable ANDROID_DEFAULT_NOTIFICATION_ICON="@mipmap/notification_icon"Older notifications can be cleared from notification center. Works on both IOS and Android.
//FCMPlugin.clearAllNotifications( successCallback(msg), errorCallback(err) );
FCMPlugin.clearAllNotifications();The old FCMPlugin.getToken is focused on retrieving the FCM Token.
For the IOS, APNS token can now be retrieved by the new method:
FCMPlugin.getAPNSToken(
function(token) {
console.info("Retrieved token: "+token)
},
function(error) {
console.error(error);
}
);On android, it will always return null.
The APNS token, once given, should not change for the same user (as commented on in https://stackoverflow.com/questions/6652242/does-the-apns-device-token-ever-change-once-created).
Although, contrary to APNS, the FCM tokens do expire, and for this reason, FCMPlugin.onTokenRefresh will be called with the new one FCM token.
Useful for IOS. On android, it will always return true.
FCMPlugin.hasPermission(function(doesIt){
// doesIt === true => yes, push was allowed
// doesIt === false => nope, push will not be available
// doesIt === null => still not answered, recommended checking again later
if(doesIt) {
haveFun();
}
});- Tested on Android and iOS using Cordova cli 6.4.0, Cordova android 6.0.0 and Cordova ios 4.3.1
- Available sdk functions: onTokenRefresh, getToken, subscribeToTopic, unsubscribeFromTopic and onNotification
- 'google-services.json' and 'GoogleService-Info.plist' are added automatically from Cordova project root to platform folders
- Added data payload parameter to check whether the user tapped on the notification or was received while in foreground.
- Free testing server available for free! https://cordova-plugin-fcm.appspot.com
Make sure you have ‘google-services.json’ for Android or ‘GoogleService-Info.plist’ for iOS in your Cordova project root folder. You don´t need to configure anything else in order to have push notification working for both platforms, everything is magic.
cordova plugin add cordova-plugin-fcm-with-dependecy-updatedGet the needed configuration files for Android or iOS from the Firebase Console (see docs: https://firebase.google.com/docs/).
Put the downloaded file 'google-services.json' in the Cordova project root folder.
You will need to ensure that you have installed the appropiate Android SDK libraries.
Put the downloaded file 'GoogleService-Info.plist' in the Cordova project root folder.
You can also test your notifications with the free testing server: https://cordova-plugin-fcm.appspot.com
//FCMPlugin.onTokenRefresh( onTokenRefreshCallback(token) );
//Note that this callback will be fired everytime a new token is generated, including the first time.
FCMPlugin.onTokenRefresh(function(token){
alert( token );
});//FCMPlugin.getToken( successCallback(token), errorCallback(err) );
//Keep in mind the function will return null if the token has not been established yet.
FCMPlugin.getToken(function(token){
alert(token);
});//FCMPlugin.subscribeToTopic( topic, successCallback(msg), errorCallback(err) );
//All devices are subscribed automatically to 'all' and 'ios' or 'android' topic respectively.
//Must match the following regular expression: "[a-zA-Z0-9-_.~%]{1,900}".
FCMPlugin.subscribeToTopic('topicExample');//FCMPlugin.unsubscribeFromTopic( topic, successCallback(msg), errorCallback(err) );
FCMPlugin.unsubscribeFromTopic('topicExample');//FCMPlugin.onNotification( onNotificationCallback(data), successCallback(msg), errorCallback(err) )
//Here you define your application behaviour based on the notification data.
FCMPlugin.onNotification(function(data){
if(data.wasTapped){
//Notification was received on device tray and tapped by the user.
alert( JSON.stringify(data) );
}else{
//Notification was received in foreground. Maybe the user needs to be notified.
alert( JSON.stringify(data) );
}

-
Application is in foreground:
The notification data is received in the JavaScript callback without notification bar message (this is the normal behaviour of mobile push notifications).
-
Application is in background or closed:
- The device displays the notification message in the device notification bar.
- If the user taps the notification, the application comes to foreground and the notification data is received in the JavaScript callback.
- If the user does not tap the notification but opens the applicacion, nothing happens until the notification is tapped.
This is a fork from https://github.com/fechanique/cordova-plugin-fcm, which has dependencies versions upgraded, jitpack and cocoapods support, and newer features.
