In this chapter, we looked at various Ionic directives and services that help us develop applications easily. We started with the Ionic Platform service, then moved on to the Header and Footer directives. Next, we went through content-related directives and navigation-related directives and services. Next, we looked into overlays. Then, we quickly went through list directives, gestures, and utility services.

With this, we have finished going through Ionic itself. From the next chapter on, we will be utilizing these components to build simple and complex applications.

In the next chapter, we will be building a Book Store app, where a user can register and log in. The user can browse through a catalog of books and add them to the cart. The user can also check them out and view the shopping history in their profile. This application shows how to integrate Ionic with a secure RESTful backend service.
