Since we'll be expanding upon the work we did in Chapter 7, Creating a Management Module for the CMS, we'll need the completed source code from the previous chapter. You can either build the project yourself, or you can use the completed source code available in the project resources folder in the previous chapter. We'll also need a URL request client that will allow us to send GET, POST, and DELETE requests with JSON-encoded data to our application. You can either use cURL, or you can download a Google Chrome extension called RESTClient available at https://chrome.google.com/webstore/detail/rest-console/cokgbflfommojglbmbpenpphppikmonn?hl=en. The examples throughout this chapter will use RESTClient.
