QuickWebApp

A quick-and-dirty api generator, for any function `a -> b` which can be wrapped inside a function `ByteString -> ByteString`. It is inspired from the interact function from Prelude.

interactWeb :: (FromLBS a, ToLBS b) => (a -> b) -> IO ()

Equivalent to 'interactWebOn 3000'

interactWebEither :: (FromLBS a, ToLBS b, ToLBS e) => (a -> Either e b) -> IO ()

Equivalent to 'interactWebEitherOn 3000'

interactWebOn :: (FromLBS a, ToLBS b) => Int -> (a -> b) -> IO ()

Create an API with a POST endpoint

interactWebEitherOn :: (FromLBS a, ToLBS b, ToLBS e) => Int -> (a -> Either e b) -> IO ()

Create an API with a POST endpoint If the function fails and returns a Left value, return a 422 response with the error in the body
