Half an hour is still an overestimation, most of these frontend tools go from 0 to hello world in a single CLI command.

On a good day, when you're using the most recent right version of MacOS, when all of the frontend tool's couple thousand dependencies isn't transiently incompatible with everything else, yes.

(If no, AI probably won't help you here either. Frontend stuff moves too fast, and there's too much of it. But then perhaps the AI model could tell you that the frontend tool you're using is a ridiculous overkill for your problem anyway.)

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

I had create-react-app break for me on the first try, because I managed to luck into some transient issue with dependencies.

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?

dotnet new <the_template>

It takes me all of 5 minutes with Phoenix

Exactly, the idea that it would take a weekend seems crazy to me. It’s certainly not something I need AI for.

Yep, it will likely work and do what it's supposed to do. But what it's supposed to do is probably only 90% of what you want: try to do anything out of what the boilerplate is setup for and you're in for hours of pain. Want SWC instead of TSC? Eslint wasn't setup, or not like you want? Prettier isn't integrated with ESlint? You want Typescript project references? Something about ES modules vs CJS? Hours and hours and hours of pain.

I understand all this stuff better than the average (although not a top 10%), and I'd be ashamed to put a number of the amount of hours I've lost on setting up boilerplate _even_ having used some sort of official generator
