Redirect Category to External URL

Thanks for this! I had a need for a set of subcategories to have one act as a redirect. Since my Customize already includes an onPageChange() check already (used to display a header on home page only) this should work as well, and thus is not hard-wired tot the full URL of the site:

<script type="text/discourse-plugin" version="0.8.19">
api.onPageChange((url) => {
       // Check if we're on the homepage 
        if (url === "/" || url === homeRoute) {
              // do custom stuff for home page
       } else if ( url=== "/c/redirect-politifora" ) {
             // category redirect
             window.location.replace( "https://politifora.com/" );
       } else {
             // do stuff on all other pages, if needed
       }
});
</script>
