Three ways to use Comlink web workers through React Hooks (and in a typesafe manner).

react-use-comlink's Issues

Failing under create-react-app dev server

When running the example under the create-react-app dev server (started via npm run start), the workers don't work on first load. However, after editing a source file the workers will start to work. If you reload the page, the workers again will stop working.

My source code is here: https://github.com/acbeers/worker-test

What I see:

• on first load, the code in useMemo is called twice. On the first call, the output at line 25 (console.log(res)) shows a resolved promise. On the second call, the promise is shown as pending.
• when clicking the "Increase from comlink" button, the output at line 31 (console.log(instance)) shows that the promise is still pending.
• after editing the source and saving, useMemo is again called twice. This time, the output at line 25 shows both promises resolve. And, the button will now work.

Have you gotten this example to work under cra's development server? Many thanks for any advice you can offer

Unexpected token '<'

I created a simple object similar to the example:

import { expose } from 'comlink'

export const SortWorker = {
  hello: 'world',
  sort() {
    return 'sort worker ran!'
  },
}

expose(SortWorker)

But I see this in the console: Uncaught SyntaxError: Unexpected token '<'

I am using create-react-app with hooks.
