The recommendation for react is to use an iframe that references the exported .html file.
Unfortunately you can’t bring in a Hype div into a react component on the page, as React will do DOM unloading that the Hype runtime does not expect. This will lead to lots of errors, and then when the DOM goes back in place it still won’t be correct.
There are more details in this post, and I’m pretty sure more discussion when searching for “react” on the forums.
