Whether you have been following the guidance for Centralized Deployment of Web Add-ins or you do not have Office 365 and you want to create a SharePoint catalog for deployment, but realize it has limitations:
App catalogs on SharePoint do not support add-in features that are implemented in the
VersionOverridesnode of the add-in manifest, such as add-in commands.
You essentially try all the options on this page and find that side loading is the only method that will work. So you give it a shot, it works and now you are wondering how to deploy that to a larger group of users.
That is where this new tool that a fellow co-worker (Marty Andren) and I created will come in handy: The Web Add-in Side Loader Tool. Here is the link to the GitHub where it and it’s documentation are located:
Please let me know if you have any questions or issues with this tool.
