Create a SharePoint App Catalog and Deploy an Add-in
A SharePoint Online tutorial by Peter Kalmström
Microsoft
has changed the behaviour in SharePoint Online, so now an
app catalog is automatically created the first time an admin
clicks on Apps >Open under 'More features' in the SharePoint
Admin center. It is now called Apps site instead of app
catalog.
An app catalog/Apps site is a type of site collection that
is used for storing web parts for your organization's internal
use. In the first demo below, Peter Kalmström shows with
steps and in a demo how to create an app catalog in SharePoint
Online.
Create an app catalog
(To perform these steps you must be a Global or SharePoint admin.)
Open the SharePoint admin center
Click on "apps" and then on the App Catalog link.
Keep the radio button selected for "Create a new
app catalog site" and click OK.
