Twig filter country_name in craft CMS

Question

Craft CMS doesn't have TWIG filter country_name. Even by default country name filter package is not available in twig. We need to install the corresponding package. https://twig.symfony.com/doc/3.x/filters/country_name.html

How can I install the package and use country_name filter in Craft CMS?

composer require twig/intl-extra installs the package. But still, the filter is not working. Am I missing anything? Is the installation method works with Craft cms?

You need to register the extension with the Twig environment. First, install the extension with Composer. Then see the code example in the documentation page you linked:

$twig = new \Twig\Environment(...);
$twig->addExtension(new IntlExtension());

This adds the extension to the environment so its filters will be available in your templates. Of course, Craft creates the Twig environment for you, so you need to use hooks to register the extension at the appropriate point in the lifecycle. You can put the following code in a simple site module:

use Twig\Extra\Intl\IntlExtension;

public function init()
{
    parent::init();

    if (Craft::$app->request->getIsSiteRequest()) {
        $extension = new IntlExtension();
        Craft::$app->view->registerTwigExtension($extension);
    }
}

See Register a Twig Extension for details.
