A Haskell bindings for Cisco Spark API
Cisco-spark-api package provides types and functions for accessing Cisco Spark REST API. The detail of Spark API is available from developer site of Cisco Spark
This package is designed to improve type safety over the API. Each entity is separately typed. JSON messages contained in REST responses are decoded into appropriate type of Haskell record. JSON messages sent in REST requests are encoded only from correct type of record.
Some Spark REST API return list of objects. Those APIs require HTTP Link Header based pagination. Haskell functions for those APIs automatically request subsequent pages as needed. Also those functions transform chunky response into seamless stream of elements.
This package also provides some sample usage in command line application style. See source under app directory of the source package.
Sending a message to a Spark Space (Room).
let auth = Authorization "your authorization token" roomId = RoomId "Room ID your message to be sent" messageText = MessageText "your message" message = CreateMessage (Just roomId) Nothing Nothing (Just messageText) Nothing Nothing createEntity auth def createMessage >>= print . getResponseBody
Following example is calling List Membership API which returns membership between Spark spaces (Room) and Spark users (Person). You can extract each Membership from Conduit pipe. The streamEntityWithFilter automatically performs pagenation when it is asked more element and last response indicated subsequent page in HTTP Link Header.
let auth = Authorization "your authorization token" filter = MembershipFilter yourRoomId Nothing Nothing runConduit $ streamEntityWithFilter auth def filter .| takeC 200 .| mapM_C print
You can find more examples in app/Main.hs
Support for Lens
This package provides many of records representing objects communicated via Cisco Spark REST API. Those records are designed to allow create lenses by Control.Lens.TH.makeFields.
Following example creates overloaded accessors for 'Person', 'Room' and 'Team'.
makeFields ''Person makeFields ''Room makeFields ''Team
You can access 'personId', 'roomId' and 'teamId' via overloaded accessor function 'id' like this.
let yourPersonId = yourPerson ^. id yourRoomId = yourRoom ^. id yourTeamId = yourTeam ^. id
This package does not provide pre-generated lenses for you because not everyone need it but you can make it by yourself so easily as described.
