beasties-webpack-plugin

Webpack plugin to inline critical CSS and lazy-load the rest. Version 0.4.2, released semi-regularly. Unlike alternatives like Critical or Penthouse, it does NOT use a headless browser, making it fast and lightweight; instead, it inlines all CSS rules used by the document. It integrates with html-webpack-plugin, supports preloading fonts, pruning unused CSS, and works with webpack-dev-server. Ships TypeScript types. Requires Node ^20.0.0 or >=22.0.0.
