No errors when "import/extensions": ["error", "ignorePackages"]

[saschanaz]

It doesn't show any errors , I had to do the following instead to get the expected behavior:

"import/extensions": ["error", "always", {
  "ignorePackages": true
}]

It seems src/rules/extensions.js allows but doesn't really expect defaultConfig to be "ignorePackages".

I’m not sure what the issue is here - the defaults can’t be changed without a semver-major bump.

[saschanaz]

Shouldn't ["error", "ignorePackages"] error for extensionless non-package module imports? Currently it never errors even when in mixed situation where some have extensions and others not.

[ljharb]

Yes, it should. Can you provide code where it’s not?

[saschanaz]

AFK but I don't see any relevant 'invalid' test in https://github.com/benmosher/eslint-plugin-import/blob/master/tests/src/rules/extensions.js

[ljharb]

True, but I’d expect it to behave the same as https://github.com/benmosher/eslint-plugin-import/blob/112a0bf442e52b25cd7029a9905df2508e191ac1/tests/src/rules/extensions.js#L298. Some example code where it doesn’t would help.
