4 Techniques for Sharing Data Across All Views in Laravel

In this article, we will explore four techniques to efficiently share data across all views in Laravel. These techniques eliminate the need to manually pass variables or data to each view, making it easier to access common information like navigation menu items or global variables in multiple views. The methods discussed include utilizing the AppServiceProvider, employing a View Composer, creating a BaseController, and implementing Middleware. Each approach offers its unique benefits and can be implemented based on your specific requirements. By implementing these techniques, you can effortlessly access shared data across your Blade views in Laravel, enhancing the overall efficiency of your web development process.

Method 1: Utilizing AppServiceProvider

To efficiently share common variables or data across all views in Laravel, you can utilize the AppServiceProvider. Here’s how:

  1. Navigate to the app/Providers/AppServiceProvider.php file in your Laravel project.
  2. Insert the following code snippet into the file:
namespace App\Providers; use Illuminate\Support\Facades\View; use Illuminate\Support\ServiceProvider; class AppServiceProvider extends ServiceProvider { public function boot(): void { View::share('myGlobalKey', 'This is our value'); } } 
  1. Replace 'myGlobalKey' with your desired key name and 'This is our value' with the actual value or data you intend to share.
  2. Create a test.blade.php file in your views folder.
  3. Add the following code to the test.blade.php file:
Test: {{ $myGlobalKey }} 
  1. Add a test route in the web.php file, like this:
Route::get('/test', function () { return view('test'); }); 
  1. Open your browser and navigate to the test route to view the result.

By following these steps, you will be able to share data across all your views using the AppServiceProvider in Laravel.

Method 2: Employing a View Composer

Another method to share data across views in Laravel is by employing a View Composer. Here’s how you can do it:

  1. Create a new View Composer by running the following command in your terminal:
php artisan make:provider ViewServiceProvider 
  1. Open the newly created file app/Providers/ViewServiceProvider.php.
  2. Add the following code to the file:
namespace App\Providers; use Illuminate\Support\Facades\View; use Illuminate\Support\ServiceProvider; class ViewServiceProvider extends ServiceProvider { public function boot(): void { View::composer('*', function ($view) { $view->with('viewComposerBasedValue', 'This is our value as shared by a view composer'); }); } } 
  1. Replace 'key' with your preferred key name and 'value' with the data you want to share.
  2. In the config/app.php file, add your custom ViewServiceProvider.

By utilizing a View Composer, you can pass data to views more flexibly and easily.

Method 3: Utilizing a BaseController

Sharing data across views can also be achieved by utilizing a BaseController. Here’s how you can do it:

  1. Generate a BaseController by running the following command in your terminal:
php artisan make:controller BaseController 
  1. In the BaseController, define a method that will be called for all requests. Open the app/Http/Controllers/BaseController.php file and add the following code:
namespace App\Http\Controllers; class BaseController extends Controller { public function __construct() { view()->share('anotherGlobalValue', 'This is another one of our values'); } } 
  1. Create another controller, for example, HomeController, by running the following command:
php artisan make:controller HomeController 
  1. Open the app/Http/Controllers/HomeController.php file and extend the BaseController:
namespace App\Http\Controllers; class HomeController extends BaseController { public function home() { return view('home'); } } 
  1. In your views folder, create a home.blade.php file and add the following code:
Test Home: {{ $anotherGlobalValue }} 
  1. Add a test route to web.php:
Route::get('/home', [\App\Http\Controllers\HomeController::class, 'home']); 

By utilizing a BaseController, you can easily set shared values in its constructor, and any controller that extends the BaseController will have access to this data in all its views.

Method 4: Employing Middleware

Another method to share data across views in Laravel is by employing Middleware. Here’s how you can do it:

  1. Create a new middleware by running the following command:
php artisan make:middleware SharedViewDataMiddleware 

2.Open the newly created middleware file, app/Http/Middleware/SharedViewDataMiddleware.php, and add the following code:

namespace App\Http\Middleware; use Closure; use Illuminate\Support\Facades\View; class SharedViewDataMiddleware { public function handle($request, Closure $next) { View::share('middlewareSharedData', 'This value was shared by our Middleware'); return $next($request); } } 
  1. Register the middleware in the $middleware property of your app/Http/Kernel.php file.

  2. Add a view, for example, some-other-view.blade.php, and add the following code:

Here is the value shared from a middleware: {{ $middlewareSharedData }} 
  1. Open the routes/web.php file and add the SharedViewDataMiddleware to a group, and inside the group, add all routes that need the shared data.

By employing middleware, you can conveniently intercept requests and perform tasks before any controller or view code is executed, thereby sharing data before it’s accessed by any of your views.

These four methods provide you with efficient ways to share data across all views in Laravel, making your development process easier and more streamlined. Whether you choose to utilize the AppServiceProvider, View Composer, BaseController, or Middleware, Laravel offers flexible options for sharing data and enhancing your web development experience.
