Mixpanel client.

MixPanel client for Haskell

Implements major features of MixPanel HTTP API:

• [x] track
• [x] alias
• [x] engage
• [ ] import
• [ ] export

Getting started

import Data.Aeson      ( (.=) )
import Data.Time.Clock ( getCurrentTime )
import GHC.Exts        ( fromList )
import MixPanel        ( Operation(Set), engage, track, alias
                       , AuthToken(..), mkEnv
                       -- reexports
                       , newManager, tlsManagerSettings)


main :: IO ()
main = do
  -- setup
  manager <- newManager tlsManagerSettings
  let env = mkEnv (AuthToken "foobar") manager

  -- track a simple event
  Right () <- track env "Played Video" mempty

  -- track an event with extra properties
  Right () <- track env "Played Video Unique per user"
    $ fromList [ "distinct_id" .= ("generated-id" :: String)
               , "customProperty" .= True ]

  -- alias the user
  Right () <- alias env "generated-id" "[email protected]"

  -- profile engagement
  now <- getCurrentTime
  Right () <- engage env "[email protected]"
    $ Set (fromList [ "$created" .= now])

  putStrLn "All good!"

Design questions

a) Why does it use Object/Array intemediate values from Data.Aeson?

TODO

• batch requests
• expose extra url query paramerers
• engage special properties more type safe?
• filter out null values in requests to mixpanel
• api support for tracking revenue.
