This library allows you to write WebSocket-capable servers.

An example server: https://github.com/jaspervdj/websockets/blob/master/example/server.lhs

An example client: https://github.com/jaspervdj/websockets/blob/master/example/client.hs

This package only supports insecure (ws://...) WebSockets. If you need secure (wss://...) websockets, consider using Wuss: https://hackage.haskell.org/package/wuss
