This video is packed with information on how Facebook uses of CSS-in-JS, code splitting, GraphQL ability to require code... I highly recommend watching if you're interested in the space.https://developers.facebook.com/videos/2019/building-the-new-facebookcom-with-react-graphql-and-relay/ …

huh?
I've been working on what seems a similar solution but I'd rather not reinvent the wheel and wait for a stable one battle tested at your scaleThere’s a Babel plugin that does all the processing and returns code that looks like: StyleSheet.inject(‘CSS HERE’); That’s done in prod and dev. In production though the extraction is as easy as taking the CSS and removing it from the JS.
