I was asked to do an Accessibility in React workshop. The content is likely to be less about React and more about HTML and JS, like my 2019 talk in Helsinki. I'm unsure how to create demos, though. Where/how do people write React these days? They usually pick a framework (Next, Gatsby, ?) first and don't create websites/apps from scratch, right!?

@matuzo next is really common, but also adds a lot of complexity on top of react. Gatsby is dying. Scaffolding an app with vite would be the modern equivalent if create-react-app I'd say.
@Ansimorph @matuzo yep, I suggest Vite too if you want to focus more on non-react things
