TypeError: zip.BlobReader is not a constructor when unzipping #340

Closed devtonhere closed 2 years ago

devtonhere commented 2 years ago
  1. I've downloaded the zip for this repository from GitHub via the UI.
  2. opened https://gildas-lormeau.github.io/zip.js/demos/demo-read-file.html
  3. choosen the downloaded zip and get the error as a JavaScript prompt:
TypeError: zip.BlobReader is not a constructor

No errors in the browser console during the unzip attempt, but there are these errors when the page loads:

This is because your browser does not support the TransformStream API. You can use the 2.4.x version to fix this here: https://github.com/gildas-lormeau/zip.js/releases/tag/v2.4.26.

Alternatively, including https://unpkg.com/web-streams-polyfill/dist/polyfill.min.js in your page should fix the issue.

Thanks, updating my firefox did help as well ;)

For the record, I added the polyfill in the demos.
