Salad Builder server build error

> **🚀 Edit: Don't use webpack, use `elm-watch` (or try parcel/vite)** (see [below](https://github.com/jfairbank/programming-elm.com/issues/16#issuecomment-3194657263) conversation)
> **🐁 Future chapters can also use `esbuild` to compile react files** for a lighter setup (see issue #17).

I'm getting a lot of deprecated, "run `npm audit fix`", and server errors when trying to install and start the Salad Builder (Chapter 6: Build Larger Applications) — wasn't sure where else to post this. I imagine you've not looked at this book in a while, but would be great to get feedback as there's _many_ dependencies and I wouldn't even know where to start! Using Node v20.18.0.
