Updated 10/18/2017 - this is an basic app that I set up to get firebase working with Ionic RC1.
####Set Firebase3 Configuration Properties
import firebase from 'firebase'
// the firebase config
const firebaseConfig = {
apiKey: '<your-key>',
authDomain: '<your-project-authdomain>',
databaseURL: '<your-database-URL>',
storageBucket: '<your-storage-bucket>'
};####Modify rollup.config.json to resolve issues with Firebase
useStrict: false,
