JBurchard Rentals is a demo rental agency website using Angular2 + TypeScript + Firebase. You can see property listings and share them to Facebook from the site.
If you log in with test@jburchard.com and Password123 you can edit the properties and watch them live reload to all other clients.
I wrote a tiny Firebase Service to integrate my live database with Angular2. It's not battle-tested by any means, but it might help you get going on your own Firebase service. Leave an issue if you have any feedback for me.
