It is the most basic type of an app for webOS TV, and it can be referred to as a packaged web app as it is provided as a package.

You submit the package of your app where all the resources are included, and when a user downloads the package and installs the app, the resources will also be installed in their device. So when there is a change to the package, code or resources, you need to submit a new package with the change.

How to create a packaged app

To create a packaged app, execute the ares-generate command with the -t basic parameter, meaning you are to create an app using the templated named basic, on webOS CLI. For more details about the command, see ares-generate.
