In earlier post we saw how to build a hello world web component using Angular 2.0 beta.
Now we will create a real-time component using Firebase. We will have 2 components:

Firebase is a powerful API to store and sync data in realtime helping front-end developers build realtime apps for the web.

Firebase also has safety and security built in to keep your data and your users data safe.
