Webpack build error with 0.18

[domoritz]

monaco-editor version: 0.18.0

Steps or JS usage snippet reproducing the issue:

I am trying to build the latest monaco with webpack but I am getting the following error:

./node_modules/monaco-editor/esm/vs/base/worker/defaultWorkerFactory.js 35:32-39
Critical dependency: require function is used in a way in which dependencies cannot be statically extracted

You can reproduce this error by cloning https://github.com/vega/editor/tree/dom/upgrade and running

yarn && yarn start

Not sure if it is related but in addition to that warning I'm also getting the following error:

After updating from 0.17.1 to 0.18.0 appeared a new bug:
Compiled with 1 warnings warning in ./node_modules/monaco-editor/esm/vs/base/worker/defaultWorkerFactory.js Critical dependency: require function is used in a way in which dependencies cannot be statically extracted

monaco: 0.18.0
webpack: 4.35.3.
worker-loader: 2.0.0

With 0.17.1 works fine.

Workers loaded like this:

import CssWorker from 'worker-loader!../node_modules/monaco-editor/esm/vs/language/css/css.worker.js'
import HtmlWorker  from 'worker-loader!../node_modules/monaco-editor/esm/vs/language/html/html.worker.js'
import TsWorker  from 'worker-loader!../node_modules/monaco-editor/esm/vs/language/typescript/ts.worker.js'
import EditorWorker from 'worker-loader!../node_modules/monaco-editor/esm/vs/editor/editor.worker.js'

const extensionMap = {
  'css': 'css',
  'scss': 'css',
  'sass': 'css',
  'less': 'css',
  'html': 'html',
  'pug': 'html',
  'inky': 'html',
  'typescript': 'js',
  'javascript': 'js',
}

const workers = {
  css: CssWorker,
  html: HtmlWorker,
  js: TsWorker,
  editor: EditorWorker,
}

self.MonacoEnvironment = {
  getWorker: function ( moduleId, label ) {
    const workerType = extensionMap.hasOwnProperty(label) ? extensionMap[label] : 'editor'
    return new workers[workerType]()
  },
}
