mqtt-hs

A Haskell MQTT client library.

A simple example, assuming a broker is running on localhost (needs -XOverloadedStrings):

import Network.MQTT
import Network.MQTT.Logger
Just mqtt <- connect defaultConfig { cLogger = warnings stdLogger }
let f t payload = putStrLn $ "A message was published to " ++ show t ++ ": " ++ show payload
subscribe mqtt NoConfirm "#" f
publish mqtt Handshake False "some random/topic" "Some content!"
