Thanks for the http-server instructions. But the results are the same when accessing the file via [http://localhost:8080](http://localhost:8080)

I actually figured out how to get it working sticking with the file approach: It turns out if I take out “crossorigin” then it works in Chrome!

There’s a discussion of this at [With \<script crossorigin=‘anonymous’\>, why is a script “blocked by CORS policy”?](https://stackoverflow.com/questions/41069330/with-script-crossorigin-anonymous-why-is-a-script-blocked-by-cors-policy/41069421)
