Thanks for the fast reply @amyegan, and I do indeed like the nextjs-fastapi example’s setup (although it might be a little more fun if it was extended to actually have the app talk to the api. 
)
However, the breeziness of that deployment kind of makes it more painful to get to the point where you realize that there needs to be either a code split or some kind of turborepo magic in order to support CI to multiple environments… I think no matter how cool things get with functions, there would always be that possiblity with serverless. I’d feel so much more confident if I had an easy approach to breaking out the backend to a reliable partner at least–with examples, ideally, to back that approach up.
Maybe some enterprising user out there already has built the templates, at least?
