Dependency
- This plugin requires css-loader to handle CssModule.
- It is also recommended that you use a file-loader to automatically move and access image resource files.
Compatibility
- Tested with webpack4
- Works fine with mini-css-extract-plugin on webpack4 (See example)
- Works with extract-text-webpack-plugin
- Works with webpack4 + extract-text-webpack-plugin 4.x
- As you would know, extract-text-webpack-plugin and mini-css-extract-plugin do not support HMR not yet. So using with these plugins is recommended on a production env.
