How is the configuration overhead? Is it relatively easy to get Vite + a custom react app template + tsx + testing up and running?

CRA is bloated, but still one of the fastest ways to get a "full app" up and running with React.

I don't think Vite has a testing story yet. As for the rest, yes, it totally is straightforward. We only had to change one line of configuration in the base template for it to work on Replit. See https://replit.com/@templates/Reactjs
