In this chapter, we explored React and Firebase in depth. We talked about the structure of the data in Firebase database and have seen that we should avoid data nesting as much as possible. We have also seen the usage of the on and once methods with respect to data reading and also the event called 'value', which gets fired when data changes in your database. We also went through the core concepts of Redux and saw how easy it is to use Redux for the state management of the application. We also looked at the difference between Presentational and Container components and how they should be designed. Then, we talked about the basics of Redux and also talked briefly about the advanced topics of Redux.

Moreover, we created a seat booking application with the usage of all three—React, Redux and Firebase—and saw a real-life practical example of the smooth integration of all them.

In the next chapter, we will explore Firebase Admin SDK and see how to implement User and Access Management.
