Enyo is an open source JavaScript framework for cross-platform mobile, desktop, TV and web applications emphasizing object-oriented encapsulation and modularity.[2] Initially developed by Palm, which was later acquired by Hewlett-Packard and then released under an Apache 2.0 license.[3] It is sponsored by LG Electronics and Hewlett-Packard.


Bootplate is a simplified way of creating an app, providing a skeleton of the program's folder tree. The Bootplate template provides a complete starter project that supports source control and cross-platform deployment out of the box. It can be used to facilitate both the creation of a new project and the preparation for its eventual deployment.[4]


  • Layout: Fittables, scrollers, lists, drawers, panels.
  • Onyx: Based on the original styled of webOS/Touchpad design but available for use on any platform.
  • Moonstone: Used by LG SmartTV apps but available for use on any platform.
  • Spotlight: To support key-based interactions and "point and click" events on remote controls and keyboards.
  • Mochi:[5] Advanced user interface library.
    Enyo Mochi UI
    It has been maintained by the community since the team behind webOS released this abandoned interface from Palm/HP as open source.[6] This library is not included on bootplate right now, but has very good design documents.[7]
  • enyo-iLib: Internationalization and localization library, it wrap ilib's functionality on Enyo apps.[8] G11n was another library that has been deprecated on newer versions of enyo.
  • Canvas
  • Extra
  • enyo-cordova: Enyo-compatible library to automatically include platform-specific Cordova library (WIP).


The following projects are built with Enyo:

Partial list of Enyo apps can be found on Enyo Apps. Some developers can be found on Enyo Developer Directory.


This is an example of a 'Hello world program' in Enyo

  name: "HelloWorld",
  kind: enyo.Control,
  content: 'Hello, World!',

new HelloWorld().write();
