Still the way I showed that it can be done is not only for class names. It is applicable to all CSS selectors out of the box. Also, it is very configurable and if you think that you are safe to have 1 character long selectors you are free to do so.
What is a bit not great that it is Webpack specific. But am sure that it can be done with other bundlers.
I don’t get this part “Real names obfuscation you can achieve” of your comment. You think that what I showed is not real obfuscation, if so why?
Thanks for the response!
