I am familiar with scotty, servant, yesod, and a few others. What are the equivalents in ocaml and are there others that do not have equivalents?
I’ll assume from those lists that there is no yesod or servant, but people generally mix and match libraries on a per application basis to build the equivalent of yesod’s surface area of functionality if desired.
The most feature-complete equivalent in the OCaml world is probably Eliom. It offers a full-stack solution. The others are subsets of that.
