The golang code is straightforward and somewhat documented so I actually have that part working just fine. I'm specifically looking for how to do that with node.js (or at least C++ as node.js is using that under the covers); I can't find any examples and the docs are about broad concepts but no information on how to actually pass those around to the node.js classes.
