ffmpeg.wasm Unhandled Runtime Error ReferenceError: SharedArrayBuffer is not defined

[PacoH]

After many false starts, following your incomplete install instructions (you omitted cd gif-maker), installing the latest brew version of node and fixing all the npm issues, I finally was able to run the development server. When I did I got this error in Chrome 106.0.5249.91:

Unhandled Runtime Error
ReferenceError: SharedArrayBuffer is not defined

Call Stack

Object.load
node_modules/@ffmpeg/ffmpeg/src/createFFmpeg.js (64:0)

If I can't fix this I give up.

Workaround is to download
https://github.com/gzuidhof/coi-serviceworker
and put the file in the public folder
and add a reference in the Head component
