Change checklist

• I have performed a self-review of my own code
• I have made corresponding changes to the documentation if necessary (this includes comments as well)
• I have added tests that prove my fix is effective or that my feature works

this looks correct, but the last time this was changed was 3 years ago..

I have a hard time believing that this issue would have gone noticed in all this time. Do you have a small reproduction repo?

Whether this field is used or not depends on the version of TypeScript you have and your tsconfig.json settings. The fields were added as a hedge against when they became more widespread but they weren't at the time so it's completely possible there was a mistake in it 😩

(aegir's config still leans on the typesVersions hack instead - this will fix that but it needs module deps to have the "types" field in the exports map entries - need to check if everything is updated now before we can merge it)

@SgtPooki the problem went unnoticed for so long cause there is not many people activating estlint-plugin-import with typescript. For reproduction https://github.com/sfroment/eslint-libp2p-reproduction.
