  A fat API exposes nearly all of a C++ object's public attributes and methods
to a consuming environment, such as a scripting language, or web client. This
can be contrasted with a conventional, or thin API, where the API is defined up
front, and the C++ object provides the implementation, most of which is private
to the C++ layer. Obviously, reflection is required to expose C++ objects to a
consuming layer like this -- this paper explores using the Classdesc system to
implement reflection of C++ objects into a JavaScript/TypeScript environment
via a RESTservice, and also via a Node.js API module.
