Warning

This Bundle is experimental and subject to change in a future release.

What is it ?

This bundle allows you to generate, stream and save PDF locally from URL, HTML, Markdown or any Office file. Different options are available depending on the source.

It also helps you to generate, stream and save images locally from URL, HTML and Markdown using a screenshot.

How to install

Install the bundle using composer :

composer require sensiolabs/gotenberg-bundle

With Symfony Flex

If you accept the Symfony Flex recipe during installation, the bundle is registered, the configuration skeleton file is created, the .env file is updated with GOTENBERG_DSN and dockerfile is also created to get the gotenberg image, you need to configure the ports related to GOTENBERG_DSN in your .env file.
The host could be updated too since it's localhost by default. If your script is run in a container, the host will be gotenberg.

You can now adapt the configuration file to your needs.

Without Symfony Flex

Caution

To use this bundle, you first need to install and configure Gotenberg 8.x.

Enable the bundle by adding it to the list of registered bundles in the config/bundles.php file of your project:

// config/bundles.php

return [
    // ...
    SensioLabs\GotenbergBundle\SensioLabsGotenbergBundle::class => ['all' => true],
];

Basic Usage

PDF

You can generate a PDF locally from URL, HTML, Markdown or any Office files.

URL

After injecting GotenbergPdfInterface you simply need to call the method url, which will return a UrlPdfBuilder instance.

UrlPdfBuilder lets you pass the URL of the page you want to convert into PDF to the method url.

namespace App\Controller;

use Sensiolabs\GotenbergBundle\GotenbergPdfInterface;

class YourController
{
    public function yourControllerMethod(GotenbergPdfInterface $gotenberg): Response
    {
        return $gotenberg->url()
            ->url('https://sensiolabs.com/fr/')
            ->generate()
            ->stream() // will return directly a stream response
        ;
    }
}

Twig

Warning

Every twig templates you pass to Gotenberg need to have the following structure.
Even Header or Footer parts.

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8" />
        <title>My PDF</title>
    </head>
    <body>
        <!-- Your code goes here -->
    </body>
</html>
namespace App\Controller;

use Sensiolabs\GotenbergBundle\GotenbergPdfInterface;

class YourController
{
    public function yourControllerMethod(GotenbergPdfInterface $gotenberg): Response
    {
        return $gotenberg->html()
            ->content('twig_simple_pdf.html.twig', [
                'my_var' => 'value'
            ])
            ->generate()
            ->stream() // will return directly a stream response
        ;
    }
}

If a template needs to link to a static asset (e.g. an image), this bundle provides a {{ gotenberg_asset() }} Twig function to generate the correct path AND add it to the builder automatically.

This function work as asset() Twig function and fetch your assets in the assets folder of your application If your files are in another folder, you can override the default value of assets_directory in your configuration file config/sensiolabs_gotenberg.yml. The path provided can be relative as well as absolute.

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8" />
        <title>PDF body</title>
    </head>
    <body>
        <main>
            <h1>Hello world!</h1>
            <img src="{{ gotenberg_asset('public/img/ceo.jpeg') }}" alt="CEO"/>
             <img src="{{ gotenberg_asset('public/img/admin.jpeg') }}" alt="Admin"/>
         </main>
    </body>
</html>

FAQ

My PDF / Screenshot is blank but I have no errors ! It may be because Gotenberg is trying to access an invalid URL (when using the `->url()` or `->route()` modes). For example if Gotenberg tries to access a page on `https://localhost:8001` but the SSL is a local provided one. Then Chromium won't be able to authorize access to the website. To fix this you can update your Gotenberg docker service as followed :
--- a/compose.yaml
+++ b/compose.yaml
@@ -1,6 +1,9 @@

   gotenberg:
     image: 'gotenberg/gotenberg:8'
+    command:

+      - '--chromium-ignore-certificate-errors'

It can also be because from Gotenberg PoV the URL of your Symfony app is not reachable. Let's say you are using symfony CLI to run your project locally with Gotenberg running in Docker. You need to configure the request_context like so :
