What are view composers in Laravel and how do I use them?

View composers are callbacks or class methods that are called when a view is rendered. They allow you to bind data to a view before it is displayed.

Can you give me an example of how to create a view composer?

Sure! You can create a view composer by defining a class and using the View::composer method in a service provider. For example:

use Illuminate\Support\Facades\View;

View::composer('profile', function ($view) {
    $view->with('user', Auth::user());
});

How do I register the view composer in my service provider?

You can register it in the boot method of your service provider. Just add the View::composer call there.

Are there any performance benefits to using view composers?

Yes, view composers can help improve performance by reducing the amount of data processing needed in your controllers, as they prepare data specifically for views.
