Nice article. One counter point though, OP uses Elm-bridge to generate Elm types from Haskell. I'd advise not to.
Elm-bridge is not maintained anymore, lacks documentation and some useful feature (no phantom types for example). https://github.com/Holmusk/elm-street is probably a more viable solution though I've never tried it!
Whoops! I misremembered. I think we originally considered elm-bridge, but we're actually using haskell-to-elm[0]. I am familiar with Veronika's work and it is consistently of high quality, so I don't doubt elm-street would be a solid choice. In fact, elm-street looks like it supports generating exhaustive sum type lists, which might be the killer feature over the alternatives that leads me to switch.
