📖 Release Notes


  • Remove unneeded CSS with ease
  • Sane default settings
  • Built on top of purgecss
  • Nuxt 2 and Nuxt 3 support (Use v1.0.0 for Nuxt2 support for now)
  • Fully tested!


  1. Add nuxt-purgecss dependency to your project
yarn add --dev nuxt-purgecss # or npm install --save-dev nuxt-purgecss
  1. Add nuxt-purgecss to the modules section of nuxt.config.{js,ts}
export default {
  modules: [
    // Simple usage

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

⚠️ If you are using Nuxt 2, please use version 1 of the module.



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


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

Enables the module when set to true.

PurgeCSS options

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


Default setup

// nuxt.config.js
export default {
  modules: [

Customize options

export default {
  modules: [

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


  • 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

Migrating from v1.x

⚠️ If you use Nuxt 2, you can't update to v2.x (yet?)

  1. The webpack mode has been removed, as Nuxt 3 supports Vite and webpack. This way, the logic is unified to use the PostCSS plugin of PurgeCSS. There is no mode anymore
  2. The config merging logic of v1 has been removed in favor of using defu. Instead of using functions, write your values as usual and they will be merged.
  3. PurgeCSS has been bumped from v2.x to v5.x - Please check the current config options
  4. Change the module key has been changed to just purgecss.
  5. In addition to enabled, all purgecss configurations can be written directly into the purgecss object.
  6. Eventually, check out the playground of the module and the [current defaults](at the default settings)!
