@18f/identity-build-sass

Stylesheet compilation utility with reasonable defaults and fast performance.

Why use it?

  • ⚡️ It's fast, since it uses native Dart Sass binary through sass-embedded, and the Rust-based Lightning CSS for autoprefixing and minification.
  • 💻 It includes a CLI, so it's easy to integrate with command-based build pipelines like NPM scripts or Makefile.
  • 🚀 It has relevant defaults, to work out of the box with minimal or no additional configuration.

Default behavior includes:

  • Optimizations enabled based on the NODE_ENV environment variable.
  • Autoprefixer configuration based on the current project's Browserslist configuration.
  • Automatically adds node_modules as a loaded path for Sass compilation.
  • Output filenames derived from the input filenames (main.css.scss becomes main.css).
  • Automatically adds required load paths for @18f/identity-design-system and @uswds/uswds.

Usage

CLI

Invoke the included build-sass executable with the source files and any relevant command flags.

npx build-sass path/to/sass/*.scss

Flags:

  • --out-dir: The output directory
  • --watch: Run in watch mode, recompiling files on change
  • --load-path: Include additional path in Sass path resolution
  • --verbose (-v): Output verbose debugging details
