css-extractor

💎 extracts class names and ids from CSS

Installing

$ npm install css-extractor

Basic Usage

var extractor = require('css-extractor');

var css = "#id, .class { color:#000 }";

extractor.extract(css);
// => ['#id','.class']

extract will return an array of all unique class names and ids

Approach

This module was designed to be lightweight, with no dependencies, using RegExp patterns to trim the input CSS content and capture the class names and ids.

Testing

Tests are performed using the tap testing framework. To run:

$ npm install
$ npm test

The main focus of the test cases is to ensure compatibility with common and uncommon syntactic features and liberties available in CSS, including:

• @media queries
• attribute selectors: #id[href='#id-like']
• arbitrary and non-mandatory spacing
• comment blocks
