# 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:

if you're using npm:

npm i --save-dev razzle-plugin-purgecss
1

if you're using yarn:

yarn add --dev razzle-plugin-purgecss
1

# 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,
      }
    }
  ],
};
