Of note v5-rc of PureScript's Halogen helps with some of the complications. It's been in RC for several months waiting for all of the documentation to wrap up, but I used it on a small project a few months ago and didn't have too many problems outside trying to understand how to wire up requestAnimationFrame to emit events on init. It's worth another look once it's released.

Some documentation on the v5 changes: https://github.com/slamdata/purescript-halogen/blob/master/d...
