Research direction

Start by reproducing the failure from queue.worker.ts and somewhere.ts using the shown workerize-loader and babel-loader configuration. Inspect how the worker bundle handles the async function and Babel runtime, then verify that calling getShuffledTracks no longer raises ReferenceError: regeneratorRuntime is not defined.

Description

documentation question

I'm trying to use this library with Babel and TypeScript, but I'm getting a weird error.

// queue.worker.ts

import { TrackData } from "modules/track/types"
import { shuffleArray } from "common/lang/array/helpers/shuffleArray"

export async function getShuffledTracks(tracks: TrackData[], active: number) {
  return shuffleArray(tracks).sort((track) => (track.id === active ? -1 : 0))
}

// somewhere.ts

import * as QueueWorker from "../queue.worker"
const worker = (QueueWorker as any)() as typeof QueueWorker

//  somewhere in the file
await worker.getShuffledTracks(...)

Then, when the function is called, I get this error:

This is what the config for the loader looks like:

const workerRule = {
  test: /\.worker\.ts$/,
  use: [
    "workerize-loader",
    {
      loader: "babel-loader",
      options: {
        presets: [
          [
            "@babel/env",
            {
              modules: false,
            },
          ],
        ],
      },
    },
  ],
}
