billstclair/elm-websocket-framework-server package at elm-lang.org
This package implements the server side of a websocket-based client/server framework written almost entirely in Elm. The client side is in billstclair/elm-websocket-framework.
The server depends on Node.js.
See the README in the Example directory for instructions on building and running the example server.
