i guess 'possibly' the holy grail could be the laraval/rails/django mental model of serving routing and page behavior from the bandend, however using the same language for back as front and having things linked up in a typesafe way. wouldnt be perfect for every situation but would have a good mental model when youre developing a web app type of product where there's little distinction between front and back and theres only one client in mind for consuming server behavior.
