How to set lang attribute on html element with Nuxt?

Question

Using the file nuxt.config.js file, head contents can be customized to add some meta, or other things:

module.exports = {
  /*
  ** Headers of the page
  */
  head: {
    title: 'awesome title',
    meta: [
      { charset: 'utf-8' },
      { name: 'viewport', content: 'width=device-width, initial-scale=1' },
      { hid: 'description', name: 'description', content: 'Nuxt.js project' }
    ],
    link: [
      { rel: 'icon', type: 'image/x-icon', href: '/favicon.ico' }
    ]
  },
  ...
}

But I can't find anything in the documentation to set attributes on the html element -- I want to set the lang attribute. Is there a way to do that?

head supports a htmlAttrs property. It will map each key:value of the object as attribute:value

module.exports = {
  head: {
    htmlAttrs: {
      lang: 'en'
    }
  }
}
