I have been trying to learn Webpack, and was trying to resolve this scenario. But no luck. I have been using mini-css-extract-plugin, sass-loader, css-loader and style-loader, and not using postCss and file loader, something like this " loader: [miniCss.loader, "css-loader", "sass-loader"] ". Can you tell me which plugin or settings forces webpack to extract multiple css files as in your example.
