Trigger javascript on clicking any page link, but before the page content loads?

Hey :wave:

There’s currently no method in the Plugin-API that will allow you to fire a script before a page transition because this has not come up before as far as I recall.

That said, you can leverage on the willTransition() action in the application route

You would use something that like this in your theme / component

// this fires after the transition
api.onPageChange((url, title) => {
  console.log("after transition");
});

// this fires right before the transition
api.modifyClass("route:application", {
  pluginId: "some-name",
  actions: {
    willTransition() {
      // run core code first
      this._super(...arguments);
      // then do some work
      console.log("before transition");
      // you can also do something like this to see what data you have
      // to work with like _router
      console.log(this)
    }
  }
});
