Overview

Renders resources by invoking a rack call to the Rails application. From my experiments rendering as of 2021, this is the most reliable way to render resources. Rendering via ‘Renderers::Controller` has lots of various subtle issues that are surprising. People don’t like surprises, so I opted to render through a slightly heavier stack.
