title: Nested routing in next js
body: <p>I've looked around Stackoverflow and the general consensus seems to be adding to my server file.</p>
  
  <p>Though I'm wondering if this is possible with NextJS's dynamic routing. </p>
  
  <p>I'm trying to achieving a route that looks something like this:</p>
  
  <pre><code>/categories/:id/articles/:id
  </code></pre>
  
  <p>I've tried doing something like this</p>
  
  <pre><code>- pages
    - categories
      - [id]
        - :id.js
        - articles
          - :id.js
  </code></pre>
  
  <p>To no avail, so perhaps this wasn't the best approach. Would I be able to achieve something like this without touching the server?</p>
