What is @types/css-tree?
@types/css-tree provides TypeScript type definitions for the css-tree library, which is a toolset for working with CSS, including parsing, generating, and transforming CSS code.
What are @types/css-tree's main functionalities?
Parsing CSS
This feature allows you to parse CSS code into an Abstract Syntax Tree (AST). The code sample demonstrates how to parse a simple CSS rule.
const csstree = require('css-tree');
const ast = csstree.parse('.example { color: red; }');
console.log(ast);
Generating CSS
This feature allows you to generate CSS code from an AST. The code sample shows how to generate CSS from a previously parsed AST.
const csstree = require('css-tree');
const ast = csstree.parse('.example { color: red; }');
const css = csstree.generate(ast);
console.log(css);
Transforming CSS
This feature allows you to transform CSS code by walking through the AST and modifying nodes. The code sample demonstrates changing the color property from red to blue.
const csstree = require('css-tree');
const ast = csstree.parse('.example { color: red; }');
csstree.walk(ast, function(node) {
if (node.type === 'Declaration' && node.property === 'color') {
node.value = csstree.parse('blue', { context: 'value' });
}
});
const css = csstree.generate(ast);
console.log(css);

postcss
PostCSS is a tool for transforming CSS with JavaScript plugins. It provides a similar functionality to css-tree in terms of parsing and transforming CSS, but it is more focused on plugin-based transformations and has a larger ecosystem of plugins.
csstools
CSSTools is a collection of tools for working with CSS, including parsers and transformers. It offers similar capabilities to css-tree but is more modular, allowing you to use only the parts you need.
rework
Rework is a plugin framework for CSS preprocessing. It allows you to parse, manipulate, and stringify CSS, similar to css-tree, but it is designed to be simpler and more lightweight.
