This chapter focused on the top of the stack: the view. You learned how to configure our Angular app to allow for routing to different views, backed by different controllers. You saw how easy it is to design a complex UI for our customer detail view.
In the next chapter, you’ll learn how to bring the actual data into the UI we’ve created. We’ll use a feature of Postgres called materialized views to make querying the data from Rails quite easy. You’ll also see how Angular’s asynchronous nature allows us to easily implement our UI using data from our database as well as from our third-party payment processor’s system.
