title: How to create dynamic route in gatsby
body: <p>I have setup gatsby project using this <a href="https://www.gatsbyjs.org/docs/quick-start" rel="noreferrer"><strong>link</strong></a>. It is working correctly. </p>
  
  <p>Now I know how to create route by defining the component inside the <strong><code>pages</code></strong> folder. But now I have a new challenge I need to create one dynamic route so that  I can pass my <strong><code>id</code></strong> in it (Just like <code>reactjs</code>).</p>
  
  <pre><code>&lt;Route path: "/path/:id"/&gt;
  </code></pre>
  
  <p>How do I do that in gatsby?</p>
