+### Executing Code In A Controller
+
+As previously discussed, Laravel Precognition with not invoke the controller, however many applications may not be using route model binding, form requests, and middleware and instead are doing this work in the controller. This is why we have created a mechanism for applications that want to use Precognition but also keep their code co-located within the controller. Imagine we have the following controller:

@timacdonald This looks awesome! We hope to adopt this as soon as possible! Any plans to when to release the npm packages - or if you would make the repositories public while they're getting worked on? 🙏

I would also love to try it, I have been following the PR's since Laracon 😅

+### Handling Precognitive Requests
+
+Precognitive requests should generally be side-effect free. This is where the Precognition "pattern" comes in. It is recommend when you add Precognition to your routes that you consider the side-effects triggered in your application's middleware and form requests. If the side-effects present should be skipped for precognitive requests, you may need to add a conditional around the side-effect.

+### Working With Vue and Inertia
+
+Inertia has a built-in form helper that makes working with forms a lovely experience. We wanted to maintain this experience while enabling realtime validation with Precognition, so we decided to wrap Inertia's form helper.


Any plans to support React too?
