800 lines config to compile code that's later interpreted is wild. I get the general idea behind having a script instead of a static config, so you can do some runtime config (whether or not we should have runtime changes to config is a different conversation), but this is absurd.

I'm a big believer in fully reviewing all LLM generated code, but if I had to generate and review a webpack config like this, my eyes would gloss over...

No no no, the script on the link was BEFORE llms. That was how it used to be done before. That was the recommended facebook way.

The LLM generated vite config is 20 lines
