PostCSS SCSS Parser

postcss-scss is a PostCSS syntax parser specifically designed to handle SCSS files, enabling the vast ecosystem of PostCSS plugins to process SCSS source code. Currently at version 4.0.9, this module's primary function is to interpret SCSS constructs such as mixins (parsed as custom at-rules) and variables (parsed as properties). It's crucial to understand that postcss-scss *does not compile SCSS* into standard CSS; instead, it provides an AST (Abstract Syntax Tree) that allows PostCSS plugins to perform transformations directly on SCSS syntax. This bridges the gap between Sass development and PostCSS tooling. While `postcss-scss` itself has an irregular release cadence, it closely follows major PostCSS versions, which are actively maintained.
