These are subjects I'm very passionate about, as accessible web applications are often critically lacking accessibility to a point where they cannot be used by people with disabilities. We can do so much better. I sincerely believe that with more information, developers can make a huge impact in our users' lives.
I also wrote about this subject for Smashing Magazine a few years back, when I was working on the Angular team. The framework code might be a little dated, but the concepts still apply: https://www.smashingmagazine.com/2015/05/client-rendered-accessibility/
