On the Pineco.de blog they've posted a tutorial for those out there using Laravel's request and response handling to add in macros to modify the information in the request/response based on custom logic.
We’ve already talked about the power of the collection macros. Now let’s take a look at the request and response macros as well to explore the possibilities that extending their functionality offers.
The tutorial starts by showing the creation of a
filter request macro. This macro pulls the information out of the response and removes data that contains null values. Similarly, they show how to create a
toSpecialFormat macro on the response, formatting the response as a JSON message rather than normal output.
