Description

In our monorepo we store our internal packages under ./packages

So we tried a config like this:

rules: {
  'import/order': 'warn',
},
settings: {
  'import/internal-regex': '^internal-', //  This makes importing monorepo packages get treated as though they were 'relative-parent-imports'
  'import/external-module-folders': ['node_modules', 'packages'],
}

But that makes a non-relative import throw this unexpected error

import { foo } from 'internal-utils';
                     ^--- // Relative imports from parent directories are not allowed.

Contributor guide

Research direction
Investigate how the combination of 'internal regex' and 'external module folders' settings affects import classification in eslint plugin import. Trace the code path where imports are classified as relative parent imports and determine why internal packages matching the regex are incorrectly treated as relative parent imports.
