Oracle JavaScript Extension Toolkit (JET) empowers developers by providing a modular open source toolkit based on modern JavaScript/TypeScript, CSS3 and HTML5 design and development principles.
Oracle JET(JavaScript Extension Toolkit) is a collection of open source JavaScript libraries (Preact or Knockout based architectures) along with a set of Oracle contributed JavaScript libraries that make it as simple and efficient as possible to build applications that consume and interact with Oracle products and services, especially Oracle Cloud services.
Oracle JET is a mobile first framework with its own UX/UI design called ALTA. Native themes for Android, iOS, and Windows are also provided. This makes developers less bothered about CSS and styling as the components come with a default theme out of the box. Themes are based on SASS and the .scss source is provided for easy theme modifications if desired.
