Steps to reproduce

Using Golden Retriever and the S3 extension, configure an Uppy Uploader:

    const uppy = new Uppy()
      .use(Dashboard, { inline: true, target: uppyEl })
      .use(UppyS3, {
        endpoint: '/',
        shouldUseMultipart(file) {
          // use multipart for > 20mb files
          if (!file.size) {
            return false;
          }
          return file.size > 20 * 2 ** 20;
        }
      })
      .use(GoldenRetriever, { serviceWorker: true });

Add the service worker to your own service worker JS file as instructed in the Golden Retriever documentation:

import '@uppy/golden-retriever/lib/ServiceWorker';

Expected behavior

When restarting the browser after a period of time uploading, to simulate lost connection, the previous upload files should be displayed in the browser. Clicking "resume" should restart from the most recent chunk.

Actual behavior

Vite throws an error:

Missing "./lib/ServiceWorker" specifier in "@uppy/golden-retriever" package

And it's right: that file doesn't exist. All the Typescript in the package's src directory is appropriately transpiled, but src/ServiceWorker.js is not copied over. As a result, the Service Worker store does not function correctly - the file name and location is persisted, but the plugin cannot workout which chunk to recover from, and so just hangs (without an error message).

When I copy the contents of src/ServiceWorker.js into my Service Worker file, the resume functionality works correctly.

(Without anything in the Service Worker file, the files are found correctly, but does not know which chunk to resume from).

This feels like it could be resolved with a tsconfig change, or just renaming ServiceWorker.js to ServiceWorker.ts` and letting transpilation take hold.
