I am coming back to Sharepoint development after 6 years. I initially thought that I needed to build a SharePoint Hosted Add-In. I want to build an app that operates within a SharePoint site. It will provision some lists, have a multi-step wizard, some charts, and a dashboard. It will be role based with different functionality exposed depending on the users role.
I have learned about this new SharePoint Framework infrastructure that makes it easy to spin up single page applications using Yeoman. Playing with it, it seems I only get two options: web part or extension. Within extension the options are Application Customizer, Field Customizer, and Listview Customizer.
Is there a Yeoman template for add in?
