Have you considered authoring code without either of those tools? Then you can independently add in the appropriate tool to adjust for efficiency. Thinking in terms of the tooling first is premature optimization. Focus on the end product first, and the correct tooling (if any) will be clear.
I honestly don't think that dev workflow is even possible with most frameworks. It's not like you can take an existing website and add interactivity or extend the existing interactivity with React.
The current landscape of web tools is pretty much that you have to call your shot from the beginning or suffer a rewrite later.
That is certainly true once a framework is chosen, but before that you can prototype in many directions and extends in pieces. Extending a site to use a framework is not all or nothing.
