Best way to preload route data before accessing the route.
Before rendering the page for a given route, I want to first get the necessary data synchronously. Ideally I'd like to get the data in the page component, but I'm not opposed to doing it in the router file. I've read and tried various approaches, but part of the challenge comes from the fact that there are multiple ways to build components, and the use of certain features varies. In my case, I use CompositionAPI and syntax to build single file components. The VueRouter documentation link talks about "get before navigation" where I have access to beforeRouteEnte

Catching Guzzle exceptions
I'm trying to catch exceptions in a set of tests running on an API I'm developing, and I'm using Guzzle to consume the API methods. I have wrapped the test in a try/catch block but it still throws an unhandled exception error. Adding an event listener as described in their documentation doesn't seem to do anything. I need to be able to retrieve responses with HTTP codes 500, 401, 400, in fact any response that is not 200, because if that doesn't work the system will set the most appropriate code based on the result of the call.
