fast-sass-loader

A webpack loader for Sass/SCSS that claims 5-10x faster compilation than sass-loader by deduplicating @imports, merging all Sass files into a single compile unit, and caching results internally. Version 2.x switched from node-sass to dart-sass (npm 'sass') as the default compiler, with an `implementation` option to restore node-sass. It also provides built-in url() resolution, eliminating the need for resolve-url-loader. Key trade-offs include no source map support and limited loader configuration compared to sass-loader. Release cadence is low; last update was 2020. Requires webpack 1–5 and sass 1.x as peer dependencies.
