Yeah those would just be separate endpoints/requests. text/html vs application/json. Instead of serving a static html file that bootstraps your react app, you're serving a rendered component.

Not really any different from building say a PHP app that serves an API to a mobile app.

If the user has JavaScript turned off, the whole point of a JavaScript app is lost. You could just render all the HTML on the server like a PHP app, witch would also make Reac pointless.
