### Install wkhtmltopdf binaries for Laravel Snappy

Source: https://github.com/barryvdh/laravel-snappy/blob/master/readme.md

This section outlines how to install the wkhtmltopdf/wkhtmltoimage binaries, which are a core dependency for Laravel Snappy. It includes instructions for downloading or using Composer, and specific steps for Vagrant users to prevent common errors by moving binaries to a non-synced path and making them executable.

```bash
cp vendor/h4cc/wkhtmltoimage-amd64/bin/wkhtmltoimage-amd64 /usr/local/bin/
cp vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64 /usr/local/bin/
```

```bash
chmod +x /usr/local/bin/wkhtmltoimage-amd64 
chmod +x /usr/local/bin/wkhtmltopdf-amd64
```

### Install Laravel Snappy Composer package

Source: https://github.com/barryvdh/laravel-snappy/blob/master/readme.md

This command adds the Laravel Snappy package to your project's composer.json file and installs its dependencies. It's the first step in integrating the Snappy wrapper into your Laravel or Lumen application.

```bash
composer require barryvdh/laravel-snappy
```

### Configure wkhtmltopdf binary path in Laravel Snappy

Source: https://github.com/barryvdh/laravel-snappy/blob/master/readme.md

After publishing the configuration file, you must update the 'binary' path to point to your wkhtmltopdf installation. This is crucial for Snappy to locate and execute the underlying wkhtmltopdf/wkhtmltoimage binaries, with examples provided for Composer-installed, Vagrant-moved, and Windows paths.

```php
'binary' => base_path('vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64'),
```

```php
'binary'  => '/usr/local/bin/wkhtmltopdf-amd64',
```

```php
'binary' => '"C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf"'
```

### Generate PDFs/Images with Laravel Snappy

Source: https://github.com/barryvdh/laravel-snappy/blob/master/readme.md

This snippet demonstrates how to generate PDF or image files using the Laravel Snappy wrapper. It shows methods for creating instances via the App container, wrapper, or Facade, and covers generating from HTML, URLs, or views, with options for saving to file, inlining, or downloading. It requires the `barryvdh/laravel-snappy` package and a configured `wkhtmltopdf` executable.

```PHP
$snappy = App::make('snappy.pdf');
//To file
$html = '<h1>Bill</h1><p>You owe me money, dude.</p>';
$snappy->generateFromHtml($html, '/tmp/bill-123.pdf');
$snappy->generate('http://www.github.com', '/tmp/github.pdf');
//Or output:
return new Response(
    $snappy->getOutputFromHtml($html),
    200,
    array(
        'Content-Type'          => 'application/pdf',
        'Content-Disposition'   => 'attachment; filename="file.pdf"'
    )
);

// Using the wrapper:
$pdf = App::make('snappy.pdf.wrapper');
$pdf->loadHTML('<h1>Test</h1>');
return $pdf->inline();

// Or use the facade:
$pdf = PDF::loadView('pdf.invoice', $data);
return $pdf->download('invoice.pdf');

// You can chain the methods:
return PDF::loadFile('http://www.github.com')->inline('github.pdf');

// You can change the orientation and paper size
PDF::loadHTML($html)->setPaper('a4')->setOrientation('landscape')->setOption('margin-bottom', 0)->save('myfile.pdf');
```

### Integrate Laravel Snappy with Lumen framework

Source: https://github.com/barryvdh/laravel-snappy/blob/master/readme.md

This section provides the necessary steps to integrate Laravel Snappy into a Lumen application. It involves registering the ServiceProvider and optionally the Facades within bootstrap/app.php, and explains how to customize the configuration file by manually copying it.

```php
class_alias('Barryvdh\Snappy\Facades\SnappyPdf', 'PDF');
$app->register(Barryvdh\Snappy\LumenServiceProvider::class);
```

```php
class_alias(Barryvdh\Snappy\Facades\SnappyPdf::class, 'PDF');
class_alias(Barryvdh\Snappy\Facades\SnappyImage::class, 'SnappyImage');
```

--------------------------------

### Register Laravel Snappy Service Provider and Facades

Source: https://github.com/barryvdh/laravel-snappy/blob/master/readme.md

For Laravel applications prior to 5.5 or when manual registration is preferred, this snippet shows how to add the ServiceProvider and optional Facades to your config/app.php. Facades provide a more concise syntax for interacting with the PDF and Image generation functionalities.

```php
Barryvdh\Snappy\ServiceProvider::class,
```

```php
'PDF' => Barryvdh\Snappy\Facades\SnappyPdf::class,
'SnappyImage' => Barryvdh\Snappy\Facades\SnappyImage::class,
```

--------------------------------

### Publish Laravel Snappy configuration file

Source: https://github.com/barryvdh/laravel-snappy/blob/master/readme.md

This Artisan command publishes the default configuration file for Laravel Snappy to your application's config directory. Publishing the config file allows you to customize settings, most importantly the path to the wkhtmltopdf/wkhtmltoimage binaries.

```bash
php artisan vendor:publish --provider="Barryvdh\Snappy\ServiceProvider"
```

### Test Laravel Snappy PDF Generation with Fakes

Source: https://github.com/barryvdh/laravel-snappy/blob/master/readme.md

This snippet demonstrates how to test PDF generation in Laravel applications using the `PDF` facade's `fake` method. It allows for assertions on view rendering, data passed to views, and content within the generated PDF without actually creating a file. This method helps isolate tests and improve performance by avoiding actual file system operations.

```PHP
<?php

namespace Tests\Feature;

use Tests\TestCase;
use PDF;

class ExampleTest extends TestCase
{
    public function testPrintOrderShipping()
    {
        PDF::fake();
        
        // Perform order shipping...
        
        PDF::assertViewIs('view-pdf-order-shipping');
        PDF::assertSee('Name');
    }

    // Example usage of other assertions:
    public function testOtherAssertions()
    {
        PDF::fake();
        // ... some code that generates a PDF ...
        PDF::assertViewHas('invoiceData', ['total' => 100]);
        PDF::assertViewMissing('tempKey');
        PDF::assertSeeText('Invoice Total');
        PDF::assertDontSee('Confidential Info');
        PDF::assertFileNameIs('invoice.pdf');
    }
}
```
