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 is targeted at JavaScript developers working on client-side applications. It's 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.
