Question

I ran this:

composer require barryvdh/laravel-dompdf

Then I registered in bootstrap/app.php:

$app->register(\Barryvdh\DomPDF\ServiceProvider::class);

Then I tried to publish:

php artisan vendor:publish --provider="Barryvdh\DomPDF\ServiceProvider".

Then i got big error which bellow:

PHP Fatal error:  Uncaught ReflectionException: Class config does not exist in G:\web development  all classes\simba2\vendor\laravel\framework\src\Illuminate\Container\Container.php:809
Stack trace:

I think registering laravel-dompdf in bootstrap/app.php is meant for lumen not for laravel.

What you need to do is :

1. first remove this line $app->register(\Barryvdh\DomPDF\ServiceProvider::class); from your bootstrap/app.php

2. Open config/app.php file and incorporate DomPDF service provider in providers array along with DomPDF facade to the aliases array like so :

   • Add Barryvdh\DomPDF\ServiceProvider::class, to the providers array like below :

     'providers' => [
     /*
     * Laravel Framework Service Providers...
     */
     Illuminate\Auth\AuthServiceProvider::class,
     Illuminate\Broadcasting\BroadcastServiceProvider::class,
     Illuminate\Bus\BusServiceProvider::class,
     Illuminate\Cache\CacheServiceProvider::class,
     ...
     
     /*
     * Package Service Providers...
     */
     Barryvdh\DomPDF\ServiceProvider::class, // added here 
     
     /*
     * Application Service Providers...
     */
     App\Providers\AppServiceProvider::class,
     App\Providers\AuthServiceProvider::class,
     ...
     ],
     

   • Add 'PDF' => Barryvdh\DomPDF\Facade::class, to the aliases array like below :

      'aliases' => [
     
         'App' => Illuminate\Support\Facades\App::class,
         'Arr' => Illuminate\Support\Arr::class,
         'Artisan' => Illuminate\Support\Facades\Artisan::class,
         ...
         ...
         'PDF' => Barryvdh\DomPDF\Facade::class,
     
         ],
     

   • Save your config/app.php

3. Finally Execute the following command to publish the assets from vendor.

   php artisan vendor:publish --provider="Barryvdh\DomPDF\ServiceProvider"
   

This should solve your issue

You can start using laravel-dompdf :

use PDF;
