PostCSS CLI

Official command-line interface for PostCSS, the popular CSS post-processor. Current stable version is 11.0.1 (2024-05-??). PostCSS CLI allows you to run PostCSS plugins from the terminal, supporting input/output files, directories, glob patterns, stdin/stdout piping, and watch mode. It requires Node ≥18 and PostCSS ≥8 as a peer dependency. Unlike alternative tools like PostCSS's programmatic API or build tool plugins, this CLI is designed for direct command-line usage and scripting, with support for configuration files (postcss.config.js), custom parsers/syntaxes, and sourcemaps. Version 8.0.0 made PostCSS a peer dependency, and version 7.0.0 dropped Node 6 & 8 support. The tool is actively maintained by the PostCSS core team.
