In SharePoint 2013 Preview, you can now use a new development model, called "App". The App model provides new way to develop (100% client side) and new process to deploy custom code on a SharePoint site.

If you want to have more information about the App Model, you can consult the following links:

As all SharePoint development models, you can deploy app with PowerShell. You can find a complete index of app PowerShell commands here. 

In this article, I propose 3 simple scripts to install, update or uninstall an APP for SharePoint OnPremise. Please note that in this scripts, I assumed that :

  • The app is a 100% SharePoint hosted app
  • The app is distributed as a app package (*.app file), contained in the same folder
  • The app package or app name are not scripts parameters, but include as scripts var

Note that you can download it as a zip archive at the bottom of the page.
