I assume #9732 can be closed now? Please do, if that's right

[thymikee]

What about this one: #7364? It's a bit older but tackles the same problem space

[ganemone]

@thymikee That PR is stale and was never finished but was attempting to do the same thing.

[ganemone]

@thymikee / @SimenB could you take another look here?

[ganemone]

bump @SimenB / @thymikee - would really appreciate some movement on this. Thank you!

[ganemone]

Pinging some other people to get some movement on this: @cpojer @pedrottimark

[ganemone]

I understand these are tough times for everyone. If there is anything I can do to help move this along please let me know. Happy to add more tests, documentation, or discuss alternative approaches if you aren't happy with this approach. It would be really awesome to get this landed to unblock everyone trying to use jest with bazel.

I hope this PR will also be merged.

@SimenB do you expect to get this merged anytime soon? (please 🙏 )

[nathanmarks]

Any updates on this? @ganemone @SimenB ?

[mistic]

@SimenB can we move this PR forward? I think it makes total sense to respect the previously defined Node options or at least offer a default resolver config we can set just like webpack does 😃

Thanks @ganemone for your work.

I'm sorry the Facebook/jest team doesn't seem to care to look at this very helpful contribution.

Any updates on this? I found jest is the ONLY main stream tool that does not support this flag
