implementing React with a framework like Flask?

Been messing around with React.js, but using Flask as the framework and back end. Is something like this possible on pythonanywhere?

Yup. Definitely possible.

I'm also interessted in this topic. Can I bundle the react app directly on PA from source? Or do I neet to upload the bundle myself.

yup. that's possible. check out to get the newest version of node, after which you can just npm install / build etc.
