I’ve created a new “Edge Browser” page on the homepage with information about this issue, including suggestions on how to work around it: https://simplewebauthn.dev/docs/advanced/edge-browser

@mahnunchik Think there’s anything more I should add?

Aha, of course legacy Edge doesn’t support TextEncoder 🤦

caniuse confirms: https://caniuse.com/?search=TextEncoder

I’m torn on how to address this. SimpleWebAuthn supports “modern browsers” which I could argue omits legacy Edge for the Chromium version MS switched to. I see a couple of paths forward:

I update documentation on browser’s browser support and link to a polyfill when legacy Edge support is desired
I include a polyfill in browser

I’m inclined to go with Option 1. Option 2 would be a waste since it’d only be needed for a single now-deprecated browser.

@mahnunchik would you be willing to identify an npm polyfill package that fixes the issue? MDN also includes a spec-compliant polyfill I could link to to solve this with advice to “search NPM for ‘textencoder polyfill browser’”
