This is why NextJS is so compelling; if you want to create an SPA (just like with create-react-app), it can do that. But with built-in 0-config support for SSR and SSG, you can pick and choose where and how data-fetching and rendering happen (client or server, at build-time or request time, or any hybrid combination), using one language, one paradigm, one framework. IMHO it's the obvious foundation for any greenfield (or brownfield) React project. I've been building web-related things since 1998, and IME NextJS has the best DX and most flexibility of any framework I've encountered.
