rollup-plugin-postcss-config

Transform PostCSS in Rollup using options from a postcss config file (postcss.config.js). v2.0.0 is the latest stable release, last published in 2018. It relies on postcss-load-config to read config files and makes no assumptions about CSS output, requiring a separate plugin (e.g., rollup-plugin-string) to handle the transformed CSS. Key differentiators: minimal integration that delegates plugin configuration to standard PostCSS config files, unlike alternatives like rollup-plugin-postcss which bundle plugins internally. Breaking change in v2.0.0: uses object spread syntax, requiring Node >=8.6.0. No further updates expected.
