I'll be honest, I've never had the command line tool to setup a React / NextJS / Solid / Astro / Svelt / any framework app fail to make something that runs, ever
What exactly magic command line tool are you referring to? What cmd tool configures the frontend framework to use a particular css framework, webpack to work with your backend endpoints properly, setups cors and authentication with the backend for development, configures the backend to point to and serve the spa?
