IonFB is the first Mobile Native Web Application based on the Ionic Framework with a NATIVE Facebook Integration and can be used in any mobile application. IonFB itself is powered by Cordova, AngularJS & Ionic. It uses the official plugin for Facebook in Apache Cordova/PhoneGap.
You can integrate this native login to any of your existing cordova/phonegap apps.
The Facebook plugin for Apache Cordova allows you to use the same JavaScript code in your Cordova application as you use in your web application. However, unlike in the browser, the Cordova application will use the native Facebook app to perform Single Sign On for the user.
