icss-utils provides utilities for working with Interoperable CSS (ICSS), a standard for CSS Modules. It offers functions to extract and replace ICSS keywords like :import and :export from CSS source code. This is crucial for tools that process CSS Modules, enabling them to understand and manipulate dependencies and shared values between different style files. icss-utils greatly simplifies the handling of ICSS syntax in CSS build pipelines. By using this package, developers can easily build tools to process CSS Modules, manage dependencies, and enhance CSS interoperability.
