What is lightningcss?

LightningCSS is a high-performance CSS parser, transformer, and minifier. It is designed to handle large CSS files efficiently and provides various functionalities for CSS processing.

What are lightningcss's main functionalities?

CSS Parsing

This feature allows you to parse CSS strings into an Abstract Syntax Tree (AST). The code sample demonstrates how to parse a simple CSS string and log the resulting AST.

const { parse } = require('lightningcss');
const css = '.class { color: red; }';
const ast = parse(css);
console.log(ast);

CSS Minification

This feature enables you to minify CSS code, reducing its size for better performance. The code sample shows how to minify a CSS string and log the minified output.

const { minify } = require('lightningcss');
const css = '.class { color: red; }';
const minified = minify(css);
console.log(minified);

CSS Transformation

This feature allows you to transform CSS code based on specific targets, such as browser compatibility. The code sample demonstrates transforming a CSS string to be compatible with the specified browser targets.

const { transform } = require('lightningcss');
const css = '.class { color: red; }';
const transformed = transform(css, { targets: { browsers: ['> 1%', 'last 2 versions'] } });
console.log(transformed);
