There are a few basic assumptions that we are going to make. Having purchased or otherwise obtained this book, we assume that you are interested in developing with Splunk, and have a basic understanding of Splunk and how to navigate around the software. Knowledge of saving searches, reports, and basic dashboarding is a must, since most concepts and examples will be built upon the basics. We also assume that you have basic knowledge of HTML, CSS, JS, and some XML. Here, XML will be limited to the Splunk XML framework specifically. We would also recommend you to have knowledge of, or proficiency in, Python, RequireJS, and other web technologies such as Bower, npm, and Gulp. We will demonstrate how to use these web technologies within a Splunk application.
