You have to use the .TSX filename extension to enable it.

I was just playing with this today. I didn't realize it was so new! I filed a bug about the extension with the related emacs mode and it's already fixed: https://github.com/fxbois/web-mode/issues/585

You also need to set {"jsx": "react"} (for valid JS output) or {"jsx": "preserve"} (for JSX output) in your tsconfig.json / cli options.
