Warning when starting with react-native

[maximilize]

I get this warning when starting the metro server:

warn Package i18next-locize-backend has been ignored because it contains invalid configuration. Reason: Package exports for 'node_modules/i18next-locize-backend' do not define a './package.json' subpath

However, everything is still working as expected.

Interesting... never seen this... and also not familiar with react-native.
Same here: facebook/react-native#28710

Any help is welcome 🙏

Hi @adrai saw the similar issue in the UUID repo uuidjs/uuid#444 and there is a PR by the library maintainers that has some discussion in it and supposedly fixes the warning uuidjs/uuid#449 maybe this will help you, I believe this appears only in the repositories which support both Node and React Native environments for example.

Thanks for the info.
As I’m not familiar with react-native, can someone test if adding “./package.json” to the exports in the package.json file would help here?

[demchenkoalex]

Hi @adrai checked in our project, warning is no longer there. Opened a PR. Please double check if everything is ok in Node, I only checked React Native :)

Thank you very much.
Can you also check if this works in react-native, when requiring “i18next-locize-backend/cjs” ?

[adrai]

fyi: seems this makes no difference in Node

@demchenkoalex as soon as you confirm I will merge the PR

Works with import Locize from 'i18next-locize-backend/cjs'

I did:

• installed Locize from my commit
• in node_modules/i18next-locize-backend did yarn to install dev dependencies
• yarn compile to create cjs folder

released in v4.0.8

thank you very much for your help

I think it might make more sense to actually fix this in react-native instead of adding this workaround to every single module on npm. If you agree, feel free to give your 👍 for react-native-community/cli#1168

[demchenkoalex]

Not every single one (only the ones with node env supported) but yes, makes sense :)
