lightningcss-cli-darwin-x64

library1.32.0jsnpmunverified

Platform-specific binary for the Lightning CSS CLI tool on macOS x64 (>=1.0.0). Lightning CSS is a high-performance CSS parser, transformer, and minifier written in Rust, offering significantly faster processing than JavaScript-based tools like PostCSS and cssnano. It runs at a stable release cadence (monthly). Key differentiators: Rust-based speed, integrated vendor prefixing and syntax lowering, support for modern CSS features (nesting, layers, color-mix, etc.), and seamless integration with the Parcel bundler ecosystem. This package is the native binary for darwin x64, automatically installed by the parent lightningcss-cli package.

Known issues

gotchaThis is a platform-specific package - it only works on macOS x64. Do not install directly; use the main lightningcss-cli package which handles platform detection.

fix

Run `npm install lightningcss-cli` instead of this package.

affects: >=1.0.0

gotchaThe output file must be specified with -o flag, otherwise it prints to stdout.

fix

Add `-o output.css` to write to a file.

affects: >=1.0.0

gotchaSome CSS features like nesting require the `--targets` flag to avoid syntax errors.

fix

Specify targets with `--targets '> 0.5%, not dead'` to enable modern features.

affects: >=1.0.0

Errors
