esbuild-style-plugin

An esbuild plugin for processing CSS, SASS, LESS, and STYLUS files. Version 1.6.3. It handles CSS modules via PostCSS, supports reading postcss.config.js, and extracts CSS by default. Preprocessors are not bundled; you install only what you need (sass, less, stylus). It ships TypeScript definitions and supports both ESM and CJS builds. Key differentiators: SSR-friendly (extract: false keeps CSS modules mapping), dynamic preprocessor imports, and built-in PostCSS integration without requiring additional configuration plugins.
