quagga2 VS library

The next level up from that would be to hook up the business-specific frontend to a barcode scanner and at that point not only could both clients & business know what items are available, but also their current stock & availability.

I used the zebra crossing app ("barcode scanner") in mass scan mode to scan all my books. The app keeps a history of scanned items and you can export it as CSV. This of course is not very "nice" but a very fast way to scan all your books. There is also some JS implementation for isbn scanning which works ok. It is used by bookwyrm which is open-source (but not free software).

Honorable mention to quagga. No longer actively maintained, but there is an active fork quagga2.

The component used for the camera barcode scanner is quagga2, feel free to improve it or even replace it with another one and provide a pull request if that maybe works better. Also already partly tracked in #737.

The camera barcode scanner component used is quagga2. Scanning highly depends on lighting, the angle and so on and is IMHO generally slow and error prone. I would only use a laser scanner which is 1000 % faster and works under any lighting condition. On my phone I personally simply use the dropdown / search way, since still faster than a single camera barcode scan...

The component used is Quagga2 and there are also some options in data/config.php to tweak it.

I would solve it client side. Just write a little bit of javascript with zxing-js (https://github.com/zxing-js/library). There is also a vue package: https://www.npmjs.com/package/vue-zxing-scanner.

Very nice! I noticed that it only supports Chrome at the moment. Perhaps take a look at https://github.com/zxing-js/library which lets you scan C128 and QR (and others) from in-browser camera access --- so it works in FF, Chrome, Safari even on iOS.

The react-qr-barcode-scanner relies on zxing for decoding barcodes. I used it for some time until I discovered a bug caused by inconsistent results from reading EAN codes. I found an issue on zxing and it appeared to have been fixed. However the react-qr-barcode-scanner used an older version of zxing where this was still an issue.

There wasn't much in the ways of react things that I could find so I believe I just made my own component using zxing. It was pretty straightforward. I'll see if I can't find the code for this.

That said, it's really just a wrapper for the ZXing JavaScript library (https://github.com/zxing-js/library), so you could easily include that in your protect and initialize it yourself.

You might want to check https://openlibrary.org and its API with a web based bar code scanner e.g https://github.com/zxing-js/library then plug back to Calibre or your favorite PIM/PKM tool.

I am currently working on a project with implementations that are very similar. I went with zxing-js, which is a js port of the app written in java. seems to grab most barcodes, although the documentation for js is slim to none. I had to manually go through some of the code to understand even what functions were available to me. So far so good, I would recommend: https://github.com/zxing-js/library
