How do you expose a C++ object to a TypeScript layer or other scripting language? Russell K. Standish demonstrates an approach using a RESTService API that is scripting-language independent.

Fat API Bindings of C++ Objects into Scripting Languages

by Russell K. Standish

From the article:

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 REST service, and also via a Node.js API module.
