By utilizing web standards, XPages applications can be accessed by web clients and mobile devices, allowing the developer to deliver cross-platform applications. For the user interface, XPages focus on the web development standards HTML, CSS and JavaScript. Additionally themes can be used to manage multiple CSS files, and XPages comes with default themes, for example the OneUI theme.
For client side logic various JavaScript frameworks can be used, though XPages comes with the Dojo Toolkit and Dojo controls can be easily referenced in XPages applications. XPages also uses Dojo internally for certain functionality to make key features easier to use without having to write Dojo code. A special XPages JavaScript library contains further convenience functionality, for example for client side field validations. In addition to client side logic Dojo can also be used for rich user interface widgets and charts.
As any web application XPages applications can use REST services. XPages also provides easy mechanisms to bind data sources to UI controls so that for many scenarios no code needs to be written. Additionally XPages allows to declaratively only refresh parts of the page via Ajax when submitting data.
