Hi All,

I have made a new demo using Firebase. It uses Firebase Auth and DB Usage. I used Ionic Conferance App for template.

I have searched many tutorials, demos for Ionic 2 with Firebase connection on internet, but I could not find “simple” working example. So I studied on it than made my own demo project. I hope this will help who wants to use Ionic 2 with Firebase.

Here is the repository: [https://github.com/mg52/Ionic-v2-Firebase](https://github.com/mg52/Ionic-v2-Firebase)

Thanks!

Hey, @darbez_b4u try to change the const **myFirebaseConfig** to **firebaseConfig** as well as **myFirebaseAuthConfig** to **firebaseAuthConfig** - worked for me 🙂
