Parsnip is a rack middlware component primarily targeted to Rails 3.x developers creating RESTful apis. Particularly those tired of ActionDispatch::ParamsParser spewing internal server errors when clients supply malformed XML or JSON in the body of PUT/POST requests. Parsnip will find unparsable XML or JSON and return response with a status code of 400 and JSON or XML body content describing the parsing error encountered.
Rails: Parsnip uses the railties facility to work as a plug and play gem for Rails applications (verified with Rails 3.2.x).
