NuxtJS Error about shadow

[2A5F]

I don't know much about nuxt.js
I have to try to use nuxt.js first

if this helps you to try it out: (I am doing the shadow dom creation now manually)

I added the module with yarn install and then created a small plugin for nuxt (a required step)

// plugins/shadow.js
import Vue from 'vue'
import shadow from 'vue-shadow-dom'

export default () => {
  Vue.use(shadow)
}

and then in the nuxt.config.js I added the plugin.

-> then just using yields the error
