As one of the people sharing ways to implement Node Views React components… I fully agree with Marijn! One of the top contenders in our recent rebuild of our ProseMirror/React integration was “just stop using React for Node Views”, and it was genuinely quite appealing! In the end we decided to keep using React components for Node Views largely because we use those same components to actually render stories on nytimes.com, and sharing the components themselves means that our journalists are much more likely to see a relatively accurate representation in our editor of what their stories will look like once published. If you don’t already have a system that is built with (and heavily dependent on) React that you need to be able to share code with, I wouldn’t personally recommend looking to React for building ProseMirror-related UI
