Introduction
Lightning CSS, created by the Parcel team, is a CSS bundler written in Rust that promises to be significantly faster than PostCSS and other alternatives.
Speed
Being written in Rust, Lightning CSS processes CSS 10 to 100 times faster than PostCSS. On large projects, the difference is tremendous.
Features
Supports native nesting, autoprefixer without configuration, advanced minification, transpilation of modern CSS to older syntax, and CSS file bundling.
Bundler integration
Works as a plugin for Webpack, Vite, Parcel, and also as a standalone CLI. Integration is straightforward with no complex configuration.
Transformations
Automatically adds browser prefixes, transpiles modern CSS like layers and container queries, and optimizes colors and gradients.
Conclusion
Lightning CSS is the future of CSS processing. At Vynta, we use it to speed up builds and deliver optimized CSS to our clients.
