What are the most commonly used methods for request validation? Is it cleaner to use Form Requests or to validate directly within the controller? For example, does it make sense to separate validation rules with resource classes? One of the biggest issues we face in applications is the readability of error messages. How do you think we can make validation errors more understandable? Let’s discuss and share best practices!

I remember struggling with request validation in one of my early projects; the code got really messy when I was dealing directly with the `validate()` method inside the controller. Then I discovered Form Requests, and it was a game-changer—I moved all validation rules to separate classes, and the controller stayed clean. Especially in large projects, separating them into resource classes made a huge difference; for example, I grouped all user-related rules in a `UserRequest`, so it was immediately clear which rule applied to which endpoint.
I also spent a lot of time refining error messages, especially since API error responses weren’t user-friendly at first. Eventually, I used Laravel’s custom validation messages and language files to make the messages in the error bag more readable. For instance, I used the `messages()` method to add specific explanations for each field and rendered them properly on the frontend. This way, the backend rules became clearer, and users got more understandable feedback on the frontend.
