OneSignal Cordova Push Notification Plugin
their repository for help with everything except the unique functionality I provide.This is a plugin based on onesignal-cordova-plugin. Please visit
This plugin allows you to send background notifications on Android. To accomplish this, you must add
"content_available": true to the data object on your notification. If the app is open when this notification is received,
handleNotificationReceived will be called with the argument being a JSON object
j such that
j['payload']['additionalData'] is the data object you sent. No visible notification will be shown as long as the notification has no title or content.
