描述

Awesome library! I've just found an edge case when workerizing a module that depends on a webpack external.

In my webpack config i have:

module.exports = {
  // ...
  externals: {
    'config': JSON.stringify(config),
  },
  // ...
}

and in my worker module I have:

import * as config from 'config';

I'm using typescript in case that matters.

Here's the compilation error from webpack:

Module not found: Error: Can't resolve 'config' in '/directory/src'
 @ ./src/MyWorker.ts 1:0-33

研究方向
Investigate the workerize loader source code, particularly the part that resolves dependencies for the worker. The issue is that webpack externals are not passed to the worker bundle. A possible fix is to include the externals configuration in the worker's webpack config or to alias them. Look at the loader's implementation in src/loader.js (or similar) and the test directory for existing tests.
