There is a full copy of the zxing library in JS. It's been working great for my purposes - scanning QR and C128 Barcodes.

ZXing is/was solid. I used it for Android, then moved to (suggested) Google’s ml-kit offering around a year ago.

ZXing is pretty much abandoned now. It was anyway “kind of” from Google.

Used this in a b2b saas for a few years. Worked well and helped remove complexity in a previous way we did it that relied on a native app called pic2shop. We lost a bit of functionality specifically a clear target zone, green scanning line and better low light support. It made up for it in ease of support and reduction in perceived jank.

This is what we use as a fallback if the user doesnt have a handheld 2D scanner. Very fast & accurate in most of my testing.
