title: Set root pages directory in nuxt based on domain
body: <p>Im going to create a whitelabel project with Nuxt.</p>
  <p>Let's say i have two domains, domainA.com and domainB.com and a pages-directory like:</p>
  <pre><code>- pages
      - domainA
          - index.vue
          ...
      - domainB
          - index.vue
          - about.vue
          ...
  </code></pre>
  <p>How can I set the root routing directory on app start based on the domain?</p>
  <p>For example:</p>
  <pre><code>https://domainA.com -&gt; pages/domainA/index.vue
  https://domainB.com/about -&gt; pages/domainB/about.vue
  </code></pre>
  <p>Thanks in advance</p>
