postcss-go

Experimental: postcss-go is not production-ready. APIs and behavior may change.

Overview

postcss-go is a Go port of the core PostCSS architecture. It provides CSS parsing, AST transformation, processing, stringifying, and source map support, with Node.js packages for runtime integration.

Goals

• Be faster than PostCSS for common parse, transform, and stringify workloads.
• Stay compatible with the existing PostCSS ecosystem, including plugins and surrounding tooling.
