`require is not defined` when importing a node_module that imports a CSS file

Describe the bug

When importing a react component that imports a CSS file, vite fails with the message:

Uncaught ReferenceError: require is not defined

If you dig into the stack trace, you’ll see that the require statement is from an imported .css file (line 8 in this image):

This issue:

• Does not occur when running with create-react-app or storybook
• Occurs with any NPM dependency that imports a .css file. We discovered this issue with an internal component library, originally, but were able to reproduce it with react-date-picker, which also imports a .css file.

I expected this to work, as the documentation references being able to manage imported static assets like this: https://vitejs.dev/guide/features.html#css. But, perhaps there’s an issue when the CSS import occurs in a vendor/node_module.

Reproduction

https://github.com/blimmer/show-vite-issue

git clone https://github.com/blimmer/show-vite-issue.git
cd show-vite-issue
npm ci
npm run dev

You’ll observe the error in the console when you visit localhost:3000:

You can try this plugin https://github.com/originjs/vite-plugins/tree/main/packages/vite-plugin-commonjs

import { defineConfig } from 'vite'
import reactRefresh from '@vitejs/plugin-react-refresh'
import { esbuildCommonjs } from '@originjs/vite-plugin-commonjs'

export default defineConfig({
  plugins: [reactRefresh()],
  optimizeDeps:{
    esbuildOptions:{
      plugins:[
        esbuildCommonjs(['react-calendar','react-date-picker'])
      ]
    }
  }
})

vite-plugin-commonjs only works in vite dev mode, theoretically vite can support require in build mode. Refer to this issue https://github.com/originjs/vite-plugins/issues/9
