jsonToHaskell :: Options -> Value -> Text

Transform an Aeson Value into a complete Haskell module (as Text). This function is all that you need.

Use defaultOptions as a reasonable starting point.

simpleOptions :: Options

Simple module generation options. These are reasonable defaults for a simple module

performantOptions :: Options

Use more performant data types, use these for production apps.

data Options

Options for module generation
