Hi i used Gatsby strap and other Graphql solutions. i would do an kind of backend where you do your umbrella and or data entry. (i would use meteor for that and do an Graphql service with its data.,..) then you can model all you need in JS and in react you show depending on your requirements. And for provisioning iAd do a kind of hook which does bring together the Gatsby template data and whatever they need. my solution would enable you also to provide some backend services coming from umbrella if needed. but maybe i got your requirements wrong. It is also possible to do all in Strapi,react and Nodejs maybe https://www.youtube.com/watch?v=Oc_ITwxiG-Y&t=4760s gives you a 2nd idea thomas
