html5-qrcode VS library

I've been working on a web application that has a bar code code scanning component and I will say that while the apparent performance of this library is impressive, I am not a fan of this pricing model, and that alone pushes me to use alternative libraries [1]. As an aside, the library I'm thinking has zero issues with scanning any of the examples in your OSS comparison [2] using the demo implementation [3] (it scans bar codes despite the name being "html5-qrcode").

For a library like this, the only really appealing pricing model is a flat fee that buys unlimited use of the version I buy in perpetuity (even if that fee is several thousand dollars). I'm not, however, going to pay monthly forever for code that (1) you wrote once and is now static, (2) that you aren't hosting, and (3) that I need to integrate into my application myself. If I need support I will happily pay you a support fee. Moreover, I cannot take on the liability of my app's bar code scanner ceasing working because you decide to close your doors and then the license won't reactivate.

I recently spent quite a while researching different js barcode scanning libraries for work, so I’ll share my experience. The best free library I found was html5-qrcode. It uses zxing under the hood and it’s pretty adequate for most use cases. For any personal project it’s probably the best you’re gonna get. Like you, we found that it had trouble when barcodes were obscured, and since ours were really long code128 barcodes, it really struggled with those. Unfortunately this meant we had to pivot to one of the paid options. Dynamsoft, Scanbot, and Scandit all seem to do a really good job of picking up barcodes, so for professional use any of those 3 will probably meet your needs. From my experience Scandit seemed the best at picking up tough to read codes, so that’s the option we went with. Hopefully this is enough to get you started!

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
