Is it possible to attach existing remote event reciver to newly added document library?

Question

I am aware that I can attach remote event receiver in SharePoint Online existing document libraries using the AppInstalled event SP Add-in.

But, I would like to know the possibilities that when I create new document library in the host web, the event receiver should get automatically attached to it.

It is possible?

I thought of creating event receiver on Content Type, but it seems that it is not possible to attach event receiver on Content Type in SPO.

Answer 1

My normal approach for this would be to add a ListAdded remote event receiver to the host web in the AppInstalled event.

Now any time a new list is added in the host web your ListAdded remote event receiver will be called, and then you can attach your list event receivers as needed.
