Esri's Web AppBuilder is a HTML5/JavaScript-based application that is built with the ArcGIS API for JavaScript. It allows users to create intuitive, fast and beautiful web apps without writing a single line of code. As a developer, you can create your own focused workflows by building custom widgets which your users can then configure into their applications. In addition, you can completely customize the look and feel of the app by developing your own styles and layouts. Come to this session to learn all about customizing and extending the Web AppBuilder.
