In this chapter, you became familiar with the Google Firebase service and built a chat application that stores data in a real-time database.

You also learned how to configure databases and build user interfaces that self-update as soon as the database is updated. We created a list of groups/chat rooms that are rendered with the server-side data. Moreover, we have provided support so that messages can be rendered for a particular chat group.

Now, you can set up an authentication layer with a customizable sign-in provider based on email and password credentials.

In the next chapter, we are going to build an eBook editor that we can use to generate books in PDF format.
