Yii View Twig Renderer

The package is an extension of the Yii View Rendering Library. This extension provides a TwigTemplateRenderer that would allow you to use Twig view template engine.

Requirements

PHP 8.1 - 8.4

Installation

The package could be installed with Composer:

composer require yiisoft/view-twig

General usage

In your application, you should specify the configuration for Twig (by default, this is config/packages/yiisoft/view-twig/common.php):

use Psr\Container\ContainerInterface;
use Twig\Environment;
use Twig\Loader\FilesystemLoader;
use Twig\Loader\LoaderInterface;
use Yiisoft\Aliases\Aliases;
use Yiisoft\View\Twig\Extensions\YiiTwigExtension;

/** @var array $params */

return [
    LoaderInterface::class => static fn (Aliases $aliases) => new FilesystemLoader($aliases->get('@views'))
    Environment::class => [
        '__construct()' => ['options' => $params['yiisoft/view-twig']['options']]
    ],
];

And also add the parameters for WebView and Environment in params.php:

use Psr\Container\ContainerInterface;
use Psr\EventDispatcher\EventDispatcherInterface;
use Twig\Environment;
use Yiisoft\Aliases\Aliases;
use Yiisoft\Definitions\DynamicReference;
use Yiisoft\Definitions\Reference;
use Yiisoft\View\WebView;
use Yiisoft\View\Twig\TwigTemplateRenderer;
   
return [
    //...
    'yiisoft/view' => [
        'defaultExtension' => 'twig',
        'renderers' => [
            'twig' => Reference::to(TwigTemplateRenderer::class),
        ],
    ],
    'yiisoft/view-twig' => [
        'options' => [
            'cache' => DynamicReference::to(static fn (Aliases $aliases) => $aliases->get('@runtime/twig')),
            'charset' => 'utf-8',
            'debug' => $_ENV['YII_DEBUG'],
            //...
        ],
    ],
    //...
];

Template

All variables that were in the regular template are also available in the twig template.

The default main layout of the application template will look like this:

{% do assetManager.register(['App\\Asset\\AppAsset', 'App\\Asset\\CdnFontAwesomeAsset']) %}
{% do this.addCssFiles(assetManager.getCssFiles()) %}
{% do this.addCssStrings(assetManager.getCssStrings()) %}
{% do this.addJsFiles(assetManager.getJsFiles()) %}
{% do this.addJsStrings(assetManager.getJsStrings()) %}
{% do this.addJsVars(assetManager.getJsVars()) %}
{{ this.beginPage()|raw }}

        </section>
    {{ this.endBody()|raw }}
    </body>
</html>
{{ this.endPage(true)|raw }}

And the view template of the main page (site/index) will be as follows:

{% do this.setTitle(applicationParameters.getName()) %}

<h1 class="title">Hello!</h1>
