title: How to open the native Facebook app from a react app link?
body: <p>In my react web app I have a link to share a website url on Facebook:</p>
  
  <pre><code>&lt;Link href={`https://www.facebook.com/sharer/sharer.php?u=${this.props.shareUrl}`}&gt;
  </code></pre>
  
  <p>Share on Facebook
  
  I could also use a plain html link like so</p>
  
  <pre><code>&lt;a href={`https://www.facebook.com/sharer/sharer.php?u=${this.props.shareUrl}`}&gt;Share on Facebook&lt;/a&gt;
  </code></pre>
  
  <p>When this is clicked Safari is launched and the Facebook web page is displayed.</p>
  
  <p>What would I need to do to get the native Facebook ios or android app to launch (instead of a browser) if it is installed? Could I carry on using this link or would I need to use a share button or install the Fb SDK?</p>
