import/no-unresolved error in v3.1.0

[nightah]

It appears that some imports that previously did not have any issues with v2.7.1 now are throwing import/no-unresolved errors, specifically as follows:

/srv/repos/authelia/web/src/i18n/index.ts
  1:18  error  Unable to resolve path to module 'i18next'  import/no-unresolved

✖ 1 problem (1 error, 0 warnings)

file: /srv/repos/authelia/web/src/i18n/index.ts
error during build:
Error: 
/srv/repos/authelia/web/src/i18n/index.ts
  1:18  error  Unable to resolve path to module 'i18next'  import/no-unresolved

✖ 1 problem (1 error, 0 warnings)

You can see the IDE also highlighting the same issue:

Below is the consistent .eslintrc.js file utilised with both v2.7.1 and v3.1.0:

module.exports = {
    parser: "@typescript-eslint/parser",
    parserOptions: {
        project: "tsconfig.json",
    },
    ignorePatterns: ["build/*", "coverage/*", "!.*.js"],
    settings: {
        "import/resolver": {
            typescript: {},
        },
    },
    extends: ["react-app", "plugin:import/errors", "plugin:import/warnings", "plugin:prettier/recommended", "prettier"],
    rules: {
        "import/order": [
            "error",
            {
                groups: ["builtin", "external", "internal"],
                pathGroups: [
                    {
                        pattern: "react",
                        group: "external",
                        position: "before",
                    },
                ],
                pathGroupsExcludedImportTypes: ["react"],
                "newlines-between": "always",
                alphabetize: {
                    order: "asc",
                    caseInsensitive: true,
                },
            },
        ],
    },
};

After some google-fu it appears I can resolve the issue by including the following extends for the eslint configuration:

"plugin:import/typescript"

I'm not really sure why this seems to resolve the issue, but I'm keen to understand why this has changed between the two versions and if it is perhaps some misconfiguration on my side.

It's worthwhile mentioning that I did also read the changelog and understandably with the major version bump there are breaking changes I'm just not sure what the expected action is if there's an adjustment that should be made to work alongside said breaking changes.

A minimal reproduction is required.

3.0 is a major version, read CHANGELOG if you want to know what's changed.

Thanks for your prompt response.

authelia/authelia@ac63c90 is a reproduction albeit not exactly "minimal".

3.0 is a major version, read CHANGELOG if you want to know what's changed.

I did read the changelog to see what has changed, hence the last sentence in the issue.
What isn't clear is:

1. What migration steps are necessary (if any at all)
2. Expected behaviour with any of the aforementioned breaking changes (which makes it hard to ascertain if the issues are because of the breaking changes or a side-effect)

[JounQin]

No breaking excepted but we did change the deps and support exports in package.json, so it's a major version.

Thanks for provide the reproduction link, I'll take a look later.

[JounQin]

This could be related to we support exports in package.json in v3.

It could be related to https://unpkg.com/browse/i18next@21.8.10/dist/esm/package.json.

Maybe it is not supported in [enhanced-resolve](https://github.com/webpack/enhanced-resolve), maybe you raise an issue there instead.

Find an option conditionNames we should use.
