Now that we know that customizations are
deployed in the app catalog, let's see how
we can manage it. First of all, the tenant
level app catalog is the central location
to deploy add-ins for SharePoint and
Office. The add-ins deployed here are
available in each site inside of the
tenant, and you may only have one tenant
level app catalog per tenant. Now the site
collection level app catalog allows you to
deploy add-ins of SharePoint Framework
solutions for only a specific site. It is
not enabled by default so it must be
enabled by an administrator with
PowerShell and every single site that you
want to enable it on. So let's see how do
we enable it? To enable it, we first need
to get a reference to the site where the
app catalog should be created so I'm
running the Get-SPOSite PowerShell cmdlet,
and then I will use the
Add-SPOSiteCollectionAppCatalog PowerShell cmdlet to enable it on that site.
