Which oth

Answer 1

I've used the "https" and the "url" package, so those at least is pre-installed. There are quite a few standard node.js modules which need a native layer.

Clearly the AWS modules are in there, for communicating with AWS services. I've used SQS, for example.

Haven't tried "fs" yet, but since it requires a native layer, and is something you might want to do (e.g. persisting stuff to /tmp) I'm assuming it's there.

Somewhere there ought to be a list. But I can't find one. Guess you just have to try, and if the requires fails, then you need to put a module in node_modules, then see if it demands dependencies.
