What is purgecss?

PurgeCSS is a tool to remove unused CSS. It can be used as part of your development workflow to reduce the size of your CSS files by removing unused selectors.

What are purgecss's main functionalities?

Basic Usage

This code demonstrates the basic usage of PurgeCSS. It scans HTML files and CSS files to remove unused CSS selectors.

const PurgeCSS = require('purgecss');
const purgeCSSResults = new PurgeCSS().purge({
  content: ['**/*.html'],
  css: ['**/*.css']
});
console.log(purgeCSSResults);

Using with PostCSS

This code shows how to integrate PurgeCSS with PostCSS. It processes CSS files and removes unused selectors based on the content of HTML files.

const postcss = require('postcss');
const purgecss = require('@fullhuman/postcss-purgecss');

postcss([
  purgecss({
    content: ['./src/**/*.html']
  })
]).process(css, { from: 'src/app.css', to: 'dist/app.css' })
  .then(result => {
    console.log(result.css);
  });

Using with Webpack

This code demonstrates how to use PurgeCSS as a Webpack plugin. It scans the specified paths for content and removes unused CSS selectors during the Webpack build process.

const PurgeCSSPlugin = require('purgecss-webpack-plugin');
const glob = require('glob');
const path = require('path');

module.exports = {
  // other webpack config
  plugins: [
    new PurgeCSSPlugin({
      paths: glob.sync(`${path.join(__dirname, 'src')}/**/*`, { nodir: true }),
    }),
  ],
};
