I recently made a webapp for scanning barcodes using the phone camera for warehouse use. I used QuaggaJS. I disabled the barcode locator because it was too heavy, instead I just draw a box on the screen that the barcode is to be positioned in. The barcode detection and decoding happens entirely in the browser and it works very well.

I also built a web app for barcode scanning. For testing quaggaJS is fine but it’s highly inconsistent and requires an extreme degree of customization to get adequate results. I recommend scandit. It’s a good production ready library with a very nice web sdk.

Not OP, but I looked into scandit. While excellent, it's quite expensive right?

You’re right. I talked with the sales team and worked out a deal. They’re interested in user adoption.

Same here. Scandit was the best thing we tested but they quoted us $50k/yr. We don’t have many users that actually need that feature so the next best option was compiling zxing to wasm. That performed a little better than using the js version.

My team was trying to get a JS solution working as well, using zxing-js. The barcode basically had to be perfect size, on a flat surface and no glare. we ended up swapping it out for ScandIT's Web SDK and have been very please with performance. As someone else said, it is quite expensive and being a public-facing web application, we had to get a per-scan license vs device license. We're going under contract for 1 year with a "shot in the dark" scan estimate and will renegotiate next year once we have usage statistics.

Would be nice to see if this new spec gets full adoption so we can avoid high licensing fees.
