README example for collection/edge parsing?

[forsbergplustwo]

Thanks for this gem, very nicely done! When working with xxxxxFields classes, it took me a while to work out the best way to parse collections, without complicating each querying class. Came up with the following in the end:

class ProductFields
  FRAGMENT = <<-GRAPHQL
    fragment ProductFields on Product {
      id
      title
      featuredImage {
        transformedSrc(maxHeight: 300, maxWidth: 300, scale: 2)
      }
    }
  GRAPHQL

  def self.parse(product)
    OpenStruct.new(
      id: product.id,
      title: product.title,
      image_src: product.featuredImage&.transformedSrc,
    )
  end

  def self.parse_collection(products)
    products&.edges&.map do |edge|
      OpenStruct.new(
        cursor: edge.cursor,
        node: ProductFields.parse(edge.node)
      )
    end
  end
end

Happy to update README if you think it could be useful to others, or you have another suggested way?

Yeah, adding that example to README would be nice. Very useful!

BTW do you still use GraphqlResponseRubyfier for wrapping responses?

[forsbergplustwo]

Nice, will create PR :) Not using GraphqlResponseRubyfier as once I realised edges need the cursor, it was just as good going with json parse using the object_class: OpenStruct like you are. And it's much more foolproof/simpler than having the custom rybyfier.
