Before installing the PurgeCSS plugin, make sure to commit or stash your changes in case you need to revert the changes.

To install the PurgeCSS plugin simply navigate to your application folder and add PurgeCSS.

cd my-app

vue add @fullhuman/purgecss

The PurgeCSS plugin will generate a postcss.config.js file with PurgeCSS configured in it. You can then modify the PurgeCSS options.

Usage

Below are the PurgeCSS options set by this plugin:

{
  content: [ `./public/**/*.html`, `./src/**/*.vue` ],
  defaultExtractor (content) {
    const contentWithoutStyleBlocks = content.replace(/<style[^]+?<\/style>/gi, '')
    return contentWithoutStyleBlocks.match(/[A-Za-z0-9-_/:]*[A-Za-z0-9-_/]+/g) || []
  },
  safelist: [ /-(leave|enter|appear)(|-(to|from|active))$/, /^(?!(|.*?:)cursor-move).+-move$/, /^router-link(|-exact)-active$/, /data-v-.*/ ],
}
