Extract CSS Chunks Webpack Plugin

A webpack plugin that extracts CSS from chunks into separate stylesheets with Hot Module Replacement (HMR) support. Current stable version is 4.10.0 (last released November 2020). It is a fork/enhancement of mini-css-extract-plugin, adding HMR and SSR compatibility. Supports Webpack 4 and 5, ships TypeScript declarations, and is designed for code-splitting applications. Key differentiator: built-in HMR for extracted CSS files without additional loaders, and chunk-based CSS extraction for universal (SSR) apps. Active maintenance status as of 2020, but no recent releases.
