Description
I'm using i18next for translations, recently a backend connector for getting translation files was deprecated and replaced with a new package, i18next-http-backend
.
Initially firing up the app metro throws as it is unable to resolve getFetch.cjs
, adding the follow to metro.config.js removes this error:
const { getDefaultValues } = require("metro-config/src/defaults");
const {
resolver: { sourceExts }
} = getDefaultValues();
///
module.exports = {
resolver: {
extraNodeModules,
sourceExts: [...sourceExts, "cjs"]
},
}
Next, when firing up the app with react-native start
with the new package the console shows a warning:
warn Package i18next-http-backend has been ignored because it contains invalid configuration. Reason: Package subpath './package.json' is not defined by "exports" in /path/to/app/node_modules/i18next-http-backend/package.json
Looking closer into the package.json I can see it's using the latest module resolution for cjs and esm environments.
However, loading up the app on xcode simulator, the relevant requests are performed correctly and the right translation files are downloaded without any issues.
Question is, where is the warning coming from and should we be concerned?

Steps To Reproduce
Provide a detailed list of steps that reproduce the issue.
- In any react-native project
> yarn add i18next-http-backend
- Run
> react-native start
, N.B. you wont need to import the package from anywhere, I assume this warning is produced from some sort of analysis of root package.json dependencies. - See warning as first output from react-native scripts
warn Package i18next-http-backend has been ignored because it contains invalid configuration. Reason: Package subpath './package.json' is not defined by "exports" in /path/to/app/node_modules/i18next-http-backend/package.json
Expected Results
No warning is shown in the console
