Relative path '.' is transpiled to package.json main field

[juzerzarif]

I have a directory structure as follows:

src/some/directory
├── SomeModule.js
└── index.js

And I have a main field specified in my package.json: "main": "src/main.js". If I have a relative import of index.js in SomeModule.js, it gets transpiled to the main field from the package.json.

import utils from '.'; // gets transpiled to '../../main'
import utils from './'; // works

Will try to look into where the resolution is coming from a bit more after work today.

Just found where it is coming from:

babel-plugin-module-resolver/src/utils.js

Line 13 in f533cc2

return nodePath.match(/^\.?\.\//);

The method isRelativePath isn't matching ..

Fix suggestions:

1. Replacing custom matcher with !path.isAbsolutePath() (reference)
2. Refining the regex to make slash optional

This leads me to a question: is there a reason to have a custom matcher? Is there any use case where resolving . to the current package.json main entry is the desired behavior?

Too late I guess 😆
This is a duplicate of #373, and it will be fixed on #409.
