Do you have any examples or have experience with larger projects? For example, my React app has dozens of pages and some complex routing, and the backend has 50+ endpoints and talks to different databases, RabbitMQ, etc.
When I see "shoe that fits all" solutions like this I'm honestly skeptical about the degree of freedom I get for more complex architecture needs. I've found frameworks like Next.js usually give you the freedom you need because it's basically pure JS.
Also, this seems like it has a good opportunity to automatically integrate e2e/integration testing.
