Passing configuration value to twig

Question

I'm using symfony 4.0 and created a custom config file. I'm setting this config file values to a parameter, so that I can get them in a controller. But I want to pass/access them also to twig. How could I do this? Is is possible to assign the app config directly in config.yml or could I do it with a twig extension? I found getGlobals(), but this is deprecated. Still did it with a twig function, but seems not a good way to me.

Best and thank you!

AppExtension.php:

namespace AppBundle\DependencyInjection;

use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;
use Symfony\Component\Config\FileLocator;


class AppExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = $this->getConfiguration($configs, $container);
        $config = $this->processConfiguration($configuration, $configs);
        $container->setParameter('config', $config); 
    }

}

?>

Resources/config/app.yml:

app:
  document_access:
    payment:
        bank_details:
          account_owner: xxx
          iban: Iban
          bic: Bic

ConfigExtension.php

namespace AppBundle\Twig;

use Symfony\Component\DependencyInjection\ContainerInterface;

class ConfigExtension extends \Twig_Extension
{

    public function __construct(ContainerInterface $container)
    {
        $this->container = $container;
    }

    public function getFunctions(){
        return array(
            new \Twig_SimpleFunction('config', array($this, 'getConfig')),
        );
    }

    public function getConfig()
    {
        return $this->container->getParameter('config');
    }
}

Set the variables required as environtment variables and parameters.

Then you can do it injecting the parameters into you controlller or registering the variables as twig globals.

Controller

class AngularController
{
    protected $twig;
    protected $accountOwner;
    protected $iban;
    protected $bic;

    /**
     * AngularController constructor.
     * @param $accountOwner
     * @param $iban
     * @param $bic
     */
    public function __construct(\Twig_Environment $twig, $accountOwner, $iban, $bic)
    {
        $this->twig=$twig;
        $this->accountOwner = $accountOwner;
        $this->iban = $iban;
        $this->bic = $bic;
    }


    /**
     * @Route("/uri", name="your_route")
     */
    public function yourActionAction()
    {
        $data=["account_owner"=>$this->accountOwner, "iban"=>$this->iban, "bic"=>$this->bic];
        $content=$this->twig->render('Bundle:Bundle:index.html.twig', $data);
        $response=new Response($content);
        return $response;
    }
}

controller.angular:
class: DJABundle\Controller\AngularController
arguments:
    - "@twig"
    - %bank_account_owner%
    - %bank_iban%
    - %bank_bic%

Twig globals

# app/config
twig:
    [...]
    globals:
        account_owner: %bank_account_owner%
        iban: %bank_iban%
        bic: "%bank_bic%"

Usage in twig for both controller and globals

Bank account owner: {{ account_owner }}
Bank account iban: {{ iban }}
Bank account bic: {{ bic }}
