Generate API docs for your servant webservice. Feel free to also take a look at servant-pandoc which uses this package to target a broad range of output formats using the excellent pandoc.

Example

See here for the output of the following program.

{-# LANGUAGE TypeFamilies #-}
{-# LANGUAGE DeriveGeneric #-}

-- 'MimeRender' instance for 'JSON'.
instance FromJSON Greet
instance ToJSON Greet

-- We can also implement 'MimeRender' explicitly for additional formats.
instance MimeRender PlainText Greet where
    mimeRender Proxy (Greet s) = "<h1>" <> cs s <> "</h1>"

-- we provide a sample value for the 'Greet' type
