rollup-plugin-css-bundle

A Rollup plugin that collects all imported CSS files and bundles them into a single external CSS file. Version 1.0.4 (latest as of 2023) is stable but unmaintained; no updates since 2019. It preserves CSS import order and supports include/exclude filters and a transform option (e.g., for PostCSS). Unlike alternatives like rollup-plugin-postcss, it does not generate source maps, inline CSS into JS, or handle CSS modules. Simple, single-purpose tool.
