We covered a lot of information on working with modules and overcoming some of the limitations that they have. We discussed how to create a module, how to integrate it with our application, how to handle custom routing for modules, how to migrate the management functionality from a regular Yii application into our module, and we also added a file manager and upload capabilities to our CMS. Additionally, we covered different strategies for deploying our module alongside our application.

In the next chapter, we will create an API module for our application that will allow for web services and native applications to connect to our CMS. We'll expand upon the topics covered in this chapter, and we'll also cover how we can override several core Yii components to make our API flexible and easy to develop with.

Before continuing to the next chapter, be sure to review the Yii Class Reference at http://www.yiiframework.com/doc/api/ and review all the classes that we used in this chapter.
