README

A Laravel package to help convert HTML to PDF. Supports multiple drivers.

Requirements and Installation

eve/pdf-converter requires Laravel 8.x and PHP 8.x. You can install the package via Composer:

composer require eve/pdf-converter

Next, publish the config file:

php artisan vendor:publish --provider="Eve\PdfConverter\ServiceProvider"

A pdf_converter.php file will be copied into your application's config folder.

Usage

eve/pdf-converter supports 4 drivers, which can be configured in .env with the PDF_CONVERTER_DRIVER key:

• dompdf: The default. Uses laravel-dompdf under the hood.
• mock: Always returns a fixture PDF file. Doesn't do any actual conversion.
• log: Logs the input HTML and the output path using Laravel's logger. Doesn't do any actual conversion.
• pdfcrowd: Uses the commercial Pdfcrowd service. You'll have to set the PDFCROWD_USERNAME and PDFCROWD_API_KEY environment variables as well for this driver to work.

Of these drivers, mock and log are meant for development and/or testing purposes. dompdf can be used for production but will most likely require some heavy configuration, when pdfcrowd should be the best choice if you're willing to spend some bucks per month.

As eve/pdf-converter is developed first and foremost for eve's internal use, we don't have plans to add more drivers ourselves. PRs are welcome, though.

Once everything is set, the package is dead-boring. You can use either dependency injection or the facade (or both, depending on how silly you want your codebase to look).

Dependency Injection

Inject Eve\PdfConverter\PdfConverterInterface and use it:

public function __construct(private \Eve\PdfConverter\PdfConverterInterface $converter) 
{
    $this->converter->configure('key', 'value');
    
    // returns an \Illuminate\Http\File instance
    $this->converter->convertHtml('<p>Hello World</p>', '/path/to/output/file.pdf');
}

Facade

If you're a fan of Facades for whatever reason, eve/pdf-converter provides the \Eve\PdfConverter\Facades\PdfConverter facade. This facade is even aliased to \PdfConverter for your convenience.

public function generateInvoice(): void
{
    \PdfConverter::configure('key', 'value');
    \PdfConverter::convertHtml('<p>Free of charge</p>', '/my/invoice.pdf');
}

PDF Conversion Configuration

If you've been paying notice, the PDF conversion output can be tweaked via the configure method:

$converter->configure(array|string $key, ...$values);

Now, the configuration options for the PDF conversion vary from driver to driver. Specifically:

• For log and mock drivers, the configurations are completely ignored.

• For dompdf, refer to the available options supported by laravel-dompdf itself.

• For pdfcrowd, refer to the official API reference. Look for the setX() functions. You can then use X as the $key argument for configure() method and whatever setX() takes as the $values. For example:
