Included in the popular (and free!) Google Chrome web browser are some of the most useful front-end development and debugging tools you'll ever need. Even IBM i programmers with little or no background in web development can find useful elements in these tools, as they provide a mechanism for understanding what's happening with any element on a web page communicating with their IBM i server. The tools also provide an effective playground for experimenting with HTML, CSS and JavaScript concepts._x000D_ _x000D_ In this short session Rob will introduce Chrome's integrated DevTools, demonstrating how it can be used to interrogate data going between an IBM i back-end and a front-end web application, view source code, analyze visual elements and dig into other common aspects of a typical web page. The focus will be on items that would be most pertinent to RPG developers who may have little or no prior experience in programming involving web pages.
