  # Namespace for Faraday middleware used by this project.
  module Middleware

    # This middleware transforms the incoming JSON data into the format
    # expected by Her, but does so only conditionally, based on the incoming
    # content type. This allows the model's simple Her connection to be used to
    # download non-JSON content without blowing up.
    #
    # @private
    class JSONForHer < Her::Middleware::DefaultParseJSON

      # Overrides Her::Middleware::DefaultParseJSON#parse with a way to bypass
      # the default handling of a :metadata key – we want metadata to be handled
      # lazily, just like every other attribute, and we don't use the :metadata
      # key the way they expect us to.
      #

      # Overrides Her::Middleware::DefaultParseJSON#on_complete with a bail-out
      # plan - if the content-type is non-JSON, the JSON processing is skipped.
