the question of the subject is still a little vague. I hope I can be more detailed. Let me talk about my understanding.

I don't know if my understanding is correct:

By
1. , the extraction style module should refer to the extraction of the styles in the module into a file separately.
2. extracted style files can be referenced using @ import 'style file path'.

however, if you are asking about withdrawing style modules from a project, you can use the
extract-text-webpack-plugin plug-in in webpack.
