Controller Response Methods: "General" Controller or Traits

Now, I want to show you another practical example of Inheritance and Traits. What if you want to have strict rules for API responses instead of calling return response()->json() in every Controller method?

For example, see this code:

TaskController:

public function index()
{
    return response()->json([
        'success' => true,
        'data' => Task::paginate()
    ]);
}

As you can see, the API client expects success => true to be returned and the actual data in a data key.

But you don't have any guarantees that other developers on your team (including your future self) will remember to use this structure in other Controllers/methods. How do we "enforce" it?

The answer is to create specific methods to be used, like $this->respondSuccess(), $this->respondError(), and others. The question is WHERE to create them to be used in all Controllers?

I will show you two ways:

1. Use "General" Controller
2. Use Traits

Option 1. General Controller.

If you generate a Controller with php artisan make:controller, you should see it extends a...
