I ported this to React here:
https://github.com/matwerber1/aws-kinesisvideo-webrtc-react

Demo here:

My React and front-end design skills are not great - so probably room for improvement. But it seems to be working. Hope it helps!

Does this work with React Native as well?

@lherman-cs sorry, I missed your earlier message. How would you propose the structure of the PR be? Should I move the React project into a new folder, e.g. aws-samples/amazon-kinesis-video-streams-demos/react-js/*?

@CatsNipYummy I'm a React beginner - and so far, only been working in React JS. Haven't done anything in React Native before, so not sure.
