Building a QR Code HTML Web Component | Scott Jehl, Web Designer/Developer

Recently, a friend asked if I knew of a Web Component that generates a QR Code from meaningful HTML. She said that there seemed to be plenty of options for creating QR codes in general, but none that worked by extending already-useful HTML instead of just configuring it all with JavaScript. I couldn't find any either, but thinking through these kinds of patterns is probably what I enjoy most about working on the web, so I thought I'd write up how I'd make one.
