A convenient way to generate PDF files in Laravel using a headless Chrome/Chromium instance.
This package is a wrapper around chrome-php/chrome.
You may publish the config file as follows:
php artisan vendor:publish --tag=pdf-config
Here are now the basic functions of the wrapper library work:
use Mralston\Pdf\Pdf;
// Can be instantiated using a view
$pdf = Pdf::fromView('path.to.blade-template', [
'variable1' => $value1,
'variable2' => $value2,
]);
// Or with HTML
$html = '<html><head><title>test</title></head><body>...</body></html>';
$pdf = Pdf::fromHtml($html);
// Or from a URL
$pdf = Pdf::fromUrl('https://www.google.com/');
// The path to the Chrome executable can be adjusted (defaults to /usr/bin/chromium)
// This can also be done using the CHROME_BINARY environment variable
$pdf->setChromeBinary('/bin/chrome');
// Options can be passed to the Chrome rendering engine
$pdf->setOptions([
'landscape' => true,
'scale' => 0.8,
]);
// It can be instructed to emulate PhantomJS (your mileage may vary)
$pdf->emulatePhantomJs();
// The timeout can be adjusted for slow pages (defaults to 30 seconds)
$pdf->setTimeout(60);
// The PDF can be saved to disk
$pdf->save('/path/to/output.pdf');
// Or streamed to the browser
return $pdf->stream();
// Or sent to the browser as a download
return $pdf->download($filename);
Putting it all together into a (somewhat) real-world example:
use Mralston\Pdf\Pdf;
use App\Models\Invoice;
use Illuminate\Http\Response;
class InvoiceController
{
public function downloadPdf(Invoice $invoice, string $filename): Response
{
return Pdf::fromView('invoices.show', [
'invoice' => $invoice,
])
->setChromeBinary('/usr/bin/chrome')
->setOptions([
'landscape' => true,
'scale' => 0.9,
])
->setTimeout(60)
->download($filename);
}
}
