Routing With Cofree Comonad
summary
Claims a practical encoding of routing with the Cofree comonad mapping route trees to React component mounts, implements a library that parses URLs into cofree structures and folds them into elements, builds an isomorphic React app rendered server‑side with Hyper and a client router, pairs a redox DSL (free monad) with a cofree interpreter to sync front and back state, demonstrates it working and notes why extend doesn't work for tracing parse state in-place.
