This is a meta-repo that tracks all the templates that Mozilla is offering for Open Web Apps.
The following templates are available:
mortar-app-stub: a blank template for a hosted app that comes only with the basic things required to get started in app making.mortar-privileged-empty-app: an empty privileged template to quickly get started when you know what you're doing.mortar-privileged-remote-app: a privileged app template that demonstrates the usage of a privileged permission (systemXHR) to download remote content.mortar-game-stub: a minimal web game template that handles input and a render loop.mortar-list-detail: comes with a layouts library and sets up a list-detail layout for you.mortar-tab-view: a template with a tabbed layout.
And finally...
mortar-template-template, a template for building other templates. You probably don't need this one, unless you want to contribute with a brand new template and don't want to start from scratch.
You can view more documentation here.
To get all the templates at the same time, just clone this repository:
git clone --recursive https://github.com/mozilla/mortar.git
Of course, you can also separately clone the templates you're interested in.
Check out the README.md file of each template for its usage instructions.
