Web.Scotty.Binding.Play

The Play Framework style data binding in Scotty.

Data difinition:

{-# LANGUAGE TemplateHaskell #-}

import Web.Scotty.Binding.Play (deriveBindable)

data Sample = Sample
    { field1 :: Int
    , field2 :: Text
    }

deriveBindable ''Sample

set as GET parameter:

> curl http://localhost:3000/?data.field1=1&data.field2=whisky

We can get Sample in Scotty:

main :: IO ()
main = scotty 3000 $ get "/" $ do
    a <- parseParam "data"
    liftIO $ print $ field1 a --> 1
    liftIO $ print $ field2 a --> "whisky"
