I'm having fun with node.js at the moment.

My question is about intégration with a live COM Westwind situation of the RUN or ShellExecute command to communicates with nodes.js.

But maybe it could be better to create a nodes.js localhost server and communicate with json data ?

Shelling out to nodejs will be too slow and resource intensive so yeah using services is probably a better choice.

There are also .NET based NodeJs hosting options that let you basically host NodeJs inside of an existing process.

But frankly - keep it simple stick to one platform as much as possible. If you need to interop use larger chunks - silos - to isolate functionality that you can most likely reference via separate URL routes.
