Hello, thanks for the tutorial. I'm looking for ways to dynamically update the image URL in the document's head. Specifically, a meta tag using the OpenGraph protocol

<meta
      property="og:image"
      content="http://ia.media-imdb.com/images/rock.jpg" 
    /> //<-- us a cronjob to update the content property to serve a new image every day
Enter fullscreen mode Exit fullscreen mode

Is this something that a Web Worker could do?

Unfortunately, no. Web Workers can't access the DOM to make changes. You'd need to do that from the UI thread.
