A Gulp plugin that pipes CSS through PostCSS processors with a single parse for efficient CSS transformations.
gulp-postcss is a Gulp plugin that enables developers to process CSS files through PostCSS plugins within Gulp build pipelines. It solves the problem of applying multiple CSS transformations (like autoprefixing, minification, or custom syntax) efficiently by parsing CSS only once, reducing build time and complexity.
Frontend developers and build engineers using Gulp for their build processes who need to integrate PostCSS plugins for CSS preprocessing, optimization, or transformation.
Developers choose gulp-postcss because it provides a seamless, performant integration between Gulp and PostCSS, supporting flexible plugin configurations, source maps, and adherence to Gulp's single-responsibility plugin philosophy.

Parses CSS only once when applying multiple PostCSS plugins, reducing build time compared to sequential processing, as highlighted in the README's core feature.
Supports plugins via postcss.config.js, direct passing, or per-file callbacks, allowing dynamic setups like different parsers for .sss files, as shown in advanced usage examples.
Works with gulp-sourcemaps to generate accurate source maps, though it requires additional setup, enabling easy debugging of transformed CSS in Gulp tasks.
Fully integrates with any PostCSS plugin and follows PostCSS Runner Guidelines, ensuring consistent behavior and access to a wide range of CSS transformations.
Tightly coupled to Gulp, making it irrelevant for projects using alternative build systems, which restricts its applicability in modern tooling landscapes.
Processing non-standard extensions like .pcss requires additional plugins like gulp-rename, adding complexity compared to native support in other tools.
Historical updates, such as v9.1.0 breaking semver by dropping Node <18 support, indicate potential instability and upgrade challenges for long-term projects.
Relies on basic PostCSS error handling without advanced features, which can complicate debugging in complex Gulp pipelines, as noted in the changelog for CssSyntaxError.
