A CSS property value parser that uses css-tree for parsing,
and models nodes on top of PostCSS’s Node/Container/Root classes so the API feels familiar to PostCSS users.

Using npm:
npm install postcss-values-parser --save-dev- Node.js >= 20.19.0
- PostCSS >= 8.4.14 (peer dependency)
Note: This package is ESM‑only. Use import in Node.js. In CommonJS on Node >= 20.19.0, require() can load ES modules:
// CommonJS (Node >= 20.19.0) const { parse } = require('postcss-values-parser');
- Uses css-tree for fast, standards‑compliant parsing
- Builds PostCSS‑style nodes for a familiar API
- Doesn't strip characters; e.g., parentheses are preserved in the AST
- Full AST traversal
- Optional walker helpers (
registerWalkers(Container)) to walk by node type - Convenience methods to stringify nodes
- Provides convenience properties for number units, colors, etc.
Please see the Documentation for general use and further information on using the package.
