(Disclosure: I'm building Hologram)

You might find Hologram interesting for this use case - it transpiles Elixir to JavaScript so your UI runs client-side. No persistent connection needed, so no reconnection delays or error messages. Still write in Elixir, still communicate with the server when needed.

It's early stage with some rough edges, but there are already Hologram apps in production: https://hologram.page
