The code I am sharing isn’t from a widget, but it is from a component that we did release for download [here on meta](https://meta.discourse.org/t/showcased-categories-theme-component/173524).

In it we use the router, along with `@discourseComputed` to check if the route has changed, and render based on that.

You can look deeper into the code if you are interested in how it works.
