In this chapter, you learned how to work with Cordova plugins. We used camera, geolocation, and filesystem plugins and several new Sencha Touch views and controllers to implement the simple "Travelly" application. Cordova played an interesting and important part in this small project. It handled the communication between the device and JavaScript part of the application well.

The next chapter is dedicated to integration with custom services. You will learn how to use Node.js to build RESTful services and how to communicate with it from our "Travelly" application.
