For one, PHP doesn't require bundlers to work, nor does it require compilers, transpilers, watchers or whatever. You just save your code in your editor of choice and that's it.
The proposition was PHP, Laravel, Inertia and React/Vue. Pretty sure Inertia is basically a transpiler to JS, and building the components in React will use a watcher for compilation. Not sure if it has TypeScript support.
Also, you still run artisan to view your code after you save. Same thing with Python's FastAPI: I run FastAPI's server. I just save my code just like PHP.
