Firereader: a real-time content aggregator based on Firebase and Angular

There was a recent Angularjs meetup at Google that was basically about integrating Firebase and Angular.

Firebase is a backend whereas Angular would be used on the frontend.

Firebase has official integrations with Angular and Backbone and unofficial integrations with other frameworks. (https://www.firebase.com/docs/integrations.html)

Firebase is used in the example on the front page of the official AngularJS site.

Which one?

I'm assuming he's referring to Firebase.
