Provides a sensible, clean and simple way to write WebSocket-capable servers in Haskell.
The following program echoes messages back after appending meow
:
{-# LANGUAGE OverloadedStrings #-}
import Control.Monad (forever)
import qualified Data.Text as T
import qualified Network.WebSockets as WS
meow :: WS.Connection -> IO ()
meow conn = forever $ do
msg <- WS.receiveData conn
WS.sendTextData conn $ msg `T.append` ", meow"
Installation is provided using cabal:
$ cabal install websockets
An initial WebSockets library was written in 2010 by Siniša Biđin. In 2011, it was rewritten from scratch, and extended to it's current state by Jasper Van der Jeugt, who is also the current maintainer.

This library is production-quality. Therefore we have very high standards in terms of code style, API quality and testing.
We have two kinds of tests: Haskell-based tests (tests/haskell
), which use the
test-framework
library. Additionally, there are integration tests available
in tests/javascript
, which require a browser to run.
