module.parent is deprecated and doesn't work with ESM loader

[kevinoid]

As a result of nodejs/node#32217, module.parent is deprecated (DEP0144), at least in part because it is not set for a CJS module imported using the ESM loader. The deprecation causes parent-require to print a warning if node is run with --pending-deprecation (or throw if run with --throw-deprecation):

node --pending-deprecation -e "require('parent-require')('parent-require')"
(node:483687) [DEP0144] DeprecationWarning: module.parent is deprecated due to accuracy issues. Please use require.main to find program entry point instead.
(Use `node --trace-deprecation ...` to show where the warning was created)

The suggestion in the DEP0144 docs is to use require.cache with module.children to find parents:

const moduleParents = Object.values(require.cache)
  .filter((m) => m.children.includes(module));

Unfortunately, I don't think this would work with the ESM loader, which does not use require.cache. I'm not sure there is a way to support the ESM loader, but I thought it was worth opening this issue so that you are aware.

Thanks,
