Bootplate

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.^[5]

Libraries

• 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:^[6] Advanced user interface library. It has been maintained by the community since the team behind webOS released this abandoned interface from Palm/HP as open source.^[7] This library is not included on bootplate right now, but has design documents.^[8]
