Razzle

This example shows how to set up PurgeCSS with create-razzle-app template.

Installation

1. Install the packages

Once you initialized your project with npx create-razzle-app my-app, install the PurgeCSS plugin:

npm i --save-dev razzle-plugin-purgecss

yarn add --dev razzle-plugin-purgecss

2. Edit razzle.config.js

// razzle.config.js
const path = require('path');

module.exports = {
  plugins: [
    {
      name: 'purgecss',
      options: {
        // This path options is required for PurgeCSS to analyzed all of yours content
        path: path.resolve(__dirname, 'src/**/*'),
      }
    }
  ],
};

Options

• only

  You can specify entrypoints to the PurgeCSS with the option only:

  // razzle.config.js
  const path = require('path');
  
  module.exports = {
    plugins: [
      {
        name: 'purgecss',
        options: {
          path: path.resolve(__dirname, 'src/**/*'),
          only: ['bundle', 'vendor'],
        }
      }
    ],
  };
  

• whitelist (default: [])

  You can whitelist selectors to stop PurgeCSS from removing them from your CSS. This can be accomplished with the options whitelist and whitelistPatterns.

  // razzle.config.js
  const path = require('path');
  
  module.exports = {
    plugins: [
      {
        name: 'purgecss',
        options: {
          path: path.resolve(__dirname, 'src/**/*'),
          whitelist: ['random', 'yep', 'button'],
        }
      }
    ],
  };
  

• whitelistPatterns (default: [])

  You can whitelist selectors based on a regular expression with whitelistPatterns.

  // razzle.config.js
  const path = require('path');
  
  module.exports = {
    plugins: [
      {
        name: 'purgecss',
        options: {
          path: path.resolve(__dirname, 'src/**/*'),
          whitelistPatterns: [/red$/],
        }
      }
    ],
  };
  

• keyframes (default: false)

  If you are using a CSS animation library such as animate.css, you can remove unused keyframes by setting the keyframes option to true.

  // razzle.config.js
  const path = require('path');
  
  module.exports = {
    plugins: [
      {
        name: 'purgecss',
        options: {
          path: path.resolve(__dirname, 'src/**/*'),
          keyframes: true
        }
      }
    ],
  };
  

• fontFace (default: false)

  If there are any unused @font-face rules in your css, you can remove them by setting the fontFace option to true

  // razzle.config.js
  const path = require('path');
  
  module.exports = {
    plugins: [
      {
        name: 'purgecss',
        options: {
          path: path.resolve(__dirname, 'src/**/*'),
          fontFace: true,
        }
      }
    ],
  };
  

• rejected (default: false)

  It can sometimes be more practical to scan through the removed list to see if there's anything obviously wrong. If you want to do it, use the rejected option.

  // razzle.config.js
  const path = require('path');
  
  module.exports = {
    plugins: [
      {
        name: 'purgecss',
        options: {
          path: path.resolve(__dirname, 'src/**/*'),
          rejected: true,
        }
      }
    ],
  };
