How to Share Data Across All Views in Laravel 5

In Laravel 5, passing default data to all views is crucial for application consistency and ease of data access. There are multiple approaches to achieve this, each with its own advantages.

Method 1: Using BaseController

This approach involves creating a BaseController class that extends Laravel's Controller class. By setting up global variables in the constructor of the BaseController, they can be shared across all views that extend from it.

class BaseController extends Controller
{
    public function __construct()
    {
        $user = User::all();
        View::share('user', $user);
    }
}

Method 2: Using Filter

Filters provide a way to set up global variables before a request is processed. This can be useful if you need to set up data for all views, regardless of the controller or route being used.

App::before(function($request)
{
    View::share('user', User::all());
});

Method 3: Using Middleware

Middleware can be used to share data with views in a more granular way. By defining a middleware class and registering it with a specific route or group of routes, you can control which views have access to the shared data.

Route::group(['middleware' => 'SomeMiddleware'], function(){
    // routes
});

class SomeMiddleware {
    public function handle($request)
    {
        View::share('user', auth()->user());
    }
}

Method 4: Using View Composer

View composers allow you to bind specific data to views in a more flexible manner. You can create a view composer class that will run before a specific view or all views.

// Service Provider
view()->composer("ViewName","App\Http\ViewComposers\TestViewComposer");

// TestViewComposer
public function compose(View $view) {
    $view->with('ViewComposerTestVariable', "Calling with View Composer Provider");
}

Conclusion

Depending on your specific requirements, any of these methods can effectively pass data to all views in Laravel 5. Choose the approach that best suits your application architecture and ensures consistent data availability throughout your views.
