Chapter 16: Introduc/on 
to Cloud Firestore
By Dean Djermanović
In the previous chapters, you learned how to use Realtime Database for storing data 
in the cloud. Firebase offers another product that you can use for storing data in the 
cloud: 
Cloud Firestore
.
Cloud Firestore has a similar feature set as Realtime Database. It allows you store 
data in the cloud and sync data across devices, but it’s designed to overcome all of 
the drawbacks of the Realtime database — and it also stores data within a single 
JSON document. This chapter introduces you to the Cloud Firestore and discusses 
the differences between Realtime Database and Cloud Firestore. More importantly, it 
also helps you determine when it’s appropriate to use one over the other.
