CSS Hot Loader

Webpack loader for hot module replacement (HMR) of extracted CSS files, specifically designed to work with extract-text-webpack-plugin and mini-css-extract-plugin. Current stable version is 1.4.4, with low release cadence (last release in 2019). Unlike style-loader (which injects styles via <style> tags and causes FOUC), css-hot-loader enables HMR directly on extracted CSS files while preserving the document styles during JavaScript boot. Requires Webpack 4+ and mini-css-extract-plugin; Webpack 5 compatibility is unclear.
