Automatic Redirect by Path in Drupal 8

This example shows how to intercept a Drupal page request, determine if the desired path matches the one we wish to redirect, find the “latest” node of a particular content type, and redirect to that node instead of the original page.

I have a page on my site called Updates. This landing page exists only so that there is a menu item and proper breadcrumb trail; users never get to this landing page. Rather, they’re redirected to the latest update when they attempt to visit the landing page. Updates are nodes of the type update. Each update node (when viewed as a page) shows a Recent Updates block in the sidebar with links to of all of the most recent updates.

The landing page is a Views-based page (so it doesn’t get accidentally deleted). There is also an All Views-based page that lists links to all updates. If the system cannot find the latest update the user will be redirected to the All page.
