esm: convert `resolve` hook to synchronous by JakobJingleheimer · Pull Request #43363 · nodejs/node · GitHub

Notable changes

This PR converts the resolve hook from asynchronous to synchronous to align with the general ecosystem (most namely browsers). When a resolve hook returns a thenable (eg async or promise), an error is specifically thrown.

It also converts import.meta.resolve() to synchronous.

Would love to see this!

This is frustrating (due to the whatwg refusing to acknowledge that having this be async is a legitimate case) but ok. We might want to consider keeping an async alternative to this in module.
