stylus-loader

Webpack loader that compiles Stylus (.styl) files into CSS. Current stable version is 8.1.3, released February 2026, with regular bugfix updates. Maintained by the webpack team. Key differentiator: first-class webpack integration, supports webpack resolve and loaders, optional Rspack compatibility since v8.1.0, and incremental build optimization. Requires Node.js >=18.12.0 (v8) and Stylus >=0.52.4 as a peer dependency. Alternatives like stylus itself require separate CLI usage or manual integration.
