Fix node 20 reexports #30

@luxaritas I see this is a draft... Is it ready to review? |

Hey @tlhunter - main reason I left it as a draft is because I'm not confident that my approach here is "correct" - particularly how I'm handling path resolution seems hacky. That said I don't have any pending work on it, really just waiting for input, so I'll mark it as ready for review |

Thank you for implementing this!
I found a problem with circular imports that re-export. The current implementation will go into an infinite loop. This patch includes a test case for that and a proposed fix:

@luxaritas Would you be willing to add that to your branch?

Possibly this should consider Windows \\ dir separators, if on Windows? I'm not sure how important that is, and it could be done later.

To be honest the entire path handling here felt hacky when I wrote it, and I'm not sure if this is the best way to do it, though I didn't immediately come up with a better option. :)
As far as windows dir separators - I suppose? I think I initially thought cjs-module-lexer would normalize this, but in retrospect that's probably not correct. This also made me realize that importing . or .. would currently not be handled correctly either - I'll fix that up

@trentm Thanks for the patch - looks reasonable to me so I've applied it. (I've marked you as a commit coauthor using git metadata from a recent GitHub commit of yours, let me know if that should be something else!) |

If I'm not mistaken, this is solved by #43. |
