Description

Hey.

I need to store V8 callbacks as weak references, with the finalizer callback so I can remove the reference when appropriate.

I've worked out how to do this with v8::Function, but I was hoping to keep the Nan::Callback wrapper intact in case of future API changes. Unfortunately the documentation is quite bare.

Is there a way to do this?

Research direction

Start with the Nan::Callback API and the V8 callback weak-reference and finalizer approach described in the issue. Determine whether the wrapper supports SetWeak while preserving the callback, and document the supported usage and reference-removal behavior.
