react-canvas VS JsBarcode

> Building an accessible canvas-based UI with a React-like API would make a lot more sense for SPAs

React is the Simpsons of web tech.

There seems to be also a canvas library for React, called react-canvas, but it seems lacking a lot of features compared to Fabric.js.

I remember Flipboard using canvas to render their UI before using react, which has the same idea, you can look at the repo and their post about it:

React Canvas

You can also try using Canvas element in react https://github.com/Flipboard/react-canvas

I'm confused, there is react-canvas. Does it just not work very good?

As discussed previously, the barcode is the key printed part of a TR as far as access control goes. Generating a barcode by hand is tedious, but computers can do it easily. In fact, there are a lot of free software libraries that will generate barcodes for you and allow you to customize pretty much every aspect of them. For this demo, I used the JsBarcode library, which can be imported directly into a webpage without needing to download anything: https://github.com/lindell/JsBarcode

JsBarcode - Barcode generator written in JavaScript

IMO QR and bar codes are so simple you might want to consider a client-side library instead. Save some money and unnecessary dependency on a 3rd party service. I've had pretty good experience with JsBarcode for JS and python-barcode for Python...
