Warn on build when bundling code that uses nodejs built in module

[yoonminsang]

Description

I understand that vite does not provide nodejs polyfill by default.

Suggested solution

So, what if we make the build fail if we use nodejs modules? In cra, the build fails when using the fs module. But it doesn't fail with vite.
Some people apply polyfills, so how about giving an option like this: vite build no-polyfill

I think maybe a warning is enough instead of failing the build. Vite currently implements a mocked module for the builtin modules so that it emits a warning in runtime, maybe it make sense to surface it during build too.

Thanks for the reply. Thanks to vite, the development environment has improved.
I have introduced vite to an existing project that is quite large. And I'm not sure all the libraries I installed don't use nodejs built in modules. As explained in the official documentation, do not use nodejs built in modules in libraries. But like you said, I'd like to know if at least some library has this problem or not. @bluwy
