7This library lets you derive automatically Haskell functions that let you query each endpoint of a *servant* webservice.
9## Example
11``` haskell
12type MyApi = "books" :> Get [Book] -- GET /books
13 :<|> "books" :> ReqBody Book :> Post Book -- POST /books
15myApi :: Proxy MyApi
16myApi = Proxy
18getAllBooks :: BaseUrl -> EitherT String IO [Book]
19postNewBook :: Book -> BaseUrl -> EitherT String IO Book
20-- 'client' allows you to produce operations to query an API from a client.
21(getAllBooks :<|> postNewBook) = client myApi
