This library lets you automatically derive Haskell functions that let you query each endpoint of a servant webservice.
Example
{-# LANGUAGE DataKinds #-}
{-# LANGUAGE TypeOperators #-}
import Data.Proxy
import Data.Text
import Servant.API
import Servant.HttpStreams
type Book = Text
type MyApi = "books" :> Get '[JSON] [Book] -- GET /books
:<|> "books" :> ReqBody '[JSON] Book :> Post '[JSON] Book -- POST /books
myApi :: Proxy MyApi
myApi = Proxy
-- 'client' allows you to produce operations to query an API from a client.
postNewBook :: Book -> ClientM Book
getAllBooks :: ClientM [Book]
(getAllBooks :<|> postNewBook) = client myApi
-- the IOException happens already in withClientEnvIO
main' :: IO ()
