eslint-import-resolver-node can't handle "exports"

[wojtekmaj]

🐛 Bug Report

"exports" field seems to be ignored by eslint-import-resolver-node, resulting with unexpected error thrown by import/no-unresolved rule even though Node is capable of resolving the paths.

To Reproduce

Steps to reproduce the behavior:

I have a simple utils package in my workspace, that's shaped like this:

/dist
  array.js
  … 
/src
  array.js
  …
package.json

package.json:

{
  "name": "@my-org/utils",
  "version": "1.0.0",
  "exports": {
    "./array": "./dist/array.js",
    "./boolean": "./dist/boolean.js",
    "./math": "./dist/math.js",
    "./number": "./dist/number.js",
    "./object": "./dist/object.js",
    "./promise": "./dist/promise.js",
    "./string": "./dist/string.js"
  }
}

This allows me to use it in my main project by importing utils like this:

import { min } from '@my-org/utils/math'

This works both in native ES modules environment in Node 14, and in code transpiled by Babel. But this line is flagged by import/no-unresolved.

Expected behavior

"exports" to be respected and understood by eslint-import-resolver
