Features

Sane default settings
Built on top of purgecss
Nuxt 3 support

Setup

Add nuxt3-purgecss dependency to your project

yarn add --dev nuxt3-purgecss # or npm install --save-dev nuxt3-purgecss

Add nuxt3-purgecss to the modules section of nuxt.config.{js,ts}

export default {
  modules: [
    // Simple usage
    'nuxt3-purgecss',

    // With options
    ['nuxt3-purgecss', { /* module options */ }],
  ]
}

Options

Defaults

Before diving into the individual attributes, please have a look at the default settings of the module.

The defaults will scan all your .vue, .js and .ts files in the common Nuxt folders, as well as checking your nuxt.config.js (or .ts) for used classes. Furthermore, typical classes (like these needed for transitions, the nuxt link ones or those set when using scoped styles) are whitelisted already.

These settings should be a good foundation for a variety of projects.

Properties in-depth

enabled

Type: Boolean
Default: !nuxt.options.dev (Disabled during nuxt dev, enabled otherwise)

PurgeCSS options

Please read the PurgeCSS docs for information about PurgeCSS-related information.

Examples

Default setup

// nuxt.config.js
export default {
  modules: [
    'nuxt3-purgecss',
  ]
}

Customize options

//nuxt.config.js
export default {
  modules: [
    'nuxt3-purgecss',
  ],

  purgecss: {
    enabled: true, // Always enable purgecss
    safelist: ['my-class'], // Add my-class token to the safelist (e.g. .my-class)
  }
}

Caveats

Don't forget to add paths to pages and components that are not part the common folders (e.g. third party packages)
The default generated 500 and 404 pages will be purged by default. Please ensure you have an appropriate error layout
Do not use the old >>> or ::v-deep syntax. Instead, go for :deep
