In this chapter, we built a REST API to store information about pictures. Node.js handles such tasks nicely, because it has native modules. That are easy to work with. We successfully covered GET, POST, PUT, and DELETE requests, creating an interface to manage pictures. In addition, we applied basic security practices to limit unauthorized access. You also learned how to work with the service from the client.

In the next chapter, we will build a HTML5 mobile game using HTML5 Canvas and its 2D context. You will learn how to build HTML5 animations, how to handle mobile gestures, and how to deal with performance issues.
