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

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

What you need to do is :

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

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

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;
