[fregante]

• Picks up https://github.com/mozilla/addons-linter/pull/4989
• Partially includes https://github.com/mozilla/addons-linter/pull/5414
  • because Jest requires it to actually read transformIgnorePatterns correctly

@fregante sorry to let you wait on this. The fact that we're essentially adding ESM support here is a bit scary to me (not necessarily a bad thing but not as straightforward as a simple version bump). We'll be looking into converting addons-linter to ESM before the end of the year (though that might not happen for various reasons...). In the meantime, we should probably look at this PR.

[fregante]

"Adding ESM support" means bundling those ESM dependencies, with an explicit list of dependencies to bundle. No ESM dependency will actually be exposed to npm users.

Once you do publish ESM, you can just drop/revert that part of the config and it will continue working.

[willdurand]

Yeah, indeed.

Thanks for looking into this @fregante . I'm closing this PR because rather than updating the dependency, we decided to drop the dependency altogether in https://github.com/mozilla/addons-linter/pull/5520, because the feature that depended on it was not used (#5521).

[fregante]

What about the other ESM dependencies? The setup can work for other dependencies.
