Import parallel fails with "Cannot find main entry point"

[benbucksch]

Reproduction:

1. Install: yarn add https://github.com/parallel-js/parallel.js
2. Code: import Parallel from 'paralleljs';
3. Run: node --experimental-modules myapp.js (ESM experimental, using node v13.2.0)

Actual result:
Error: "Cannot find main entry point" in package.json

(node:1010476) ExperimentalWarning: The ESM module loader is experimental.
internal/modules/esm/default_resolve.js:94
  let url = moduleWrapResolve(specifier, parentURL);
            ^

}

Expected result:
Imports and runs

The fix is trivial: Add

  "main": "lib/parallel.js",

to package.json
