We work on Photon, a Clojure "extension" (like core.async) for building fullstack web UIs. It builds "managed client/sever network" into Clojure itself via a macro. The idea is to bring composability across the frontend/backend boundary by managing server IO in the same way that the JVM manages memory. Here's an example multiplayer todo app defined in one file: https://gist.github.com/dustingetz/fdd18563eb6195d3da39e6f52... — that's a full frontend/backend web app with zero "web framework boilerplate"! We believe composable/managed data sync is an abstraction step-change that brings about a new frontier in programming, like going from C++ to Java.
