Is it possible to resolve node_modules?

Hi,

I have a project where I need to determine whether the module `fs` is imported into a codebase. This must include the node_modules too.
So far I've been using `addSourceFileAtPath` with the codebase's entry and the dependencies resolved entries.

But as far as I can tell `resolveSourceFileDependencies` does not resolve the node_modules' imports.

Do you know how I can resolve the full codebase?

Start by tracing resolveSourceFileDependencies and the use of addSourceFileAtPath for the entry and dependency files. Confirm whether node_modules imports are intentionally excluded and document or implement the supported way to resolve the full codebase; no files or tests are named in the issue.
