Applications in webOS are commonly written as pure web applications. This page will give you a short overview about what is required to develop a web application for webOS and what possibilities are available.
In general a web application for webOS is just a web page with it's logic written as attached java scripts. As the history of webOS is highly coupled to the enyo web framework we're using this as our primary one. However any framework can be used and there is no requirement to stick with enyo.
In order to have a easy startup we're providing a bootplate git repository which already has everything setup to start application development.
We're support a set of common web APIs but also additional webOS specific ones. This section will give an overview what is support and what not.
We're providing a simple enyo based application template which can be used for a quick start. The repository is on github and can be found here https://github.com/webOS-ports/webos-ports-template. To start with development simply download the latest release and start developing your own application!
