Twig cache extension Bundle

, _(*1)

Symfony Bundle for twigphp/twig-cache-extension., _(*2)

API: emanueleminotto.github.io/TwigCacheBundle, _(*3)

Install bundle using Composer

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:, _(*4)

$ composer require emanueleminotto/twig-cache-bundle

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation., _(*5)

Add Bundle to AppKernel

Then, enable the bundle by adding the following line in the bundles.php file of your project:, _(*6)

// bundles.php
return [
    // ...
    EmanueleMinotto\TwigCacheBundle\TwigCacheBundle::class => ['all' => true],
    // ...
];

Configure services

This bundle allows to easily configure the caching service the extension will use for the caching. The extension by default supports instances of Doctrine\Common\Cache\Cache but allows you to use packages that provide a psr/cache-implementation., _(*7)

# app/config/config.yml
twig_cache:
    service: cache_service # instance of Doctrine\Common\Cache\Cache or Psr\Cache\CacheItemPoolInterface

Configuring a PSR-6 Cache pool implementation is possible by changing the extension's default adapter class to the PsrCacheAdapter that is provided with the extension., _(*8)

# parameters.yml
twig_cache.adapter.class: Twig\CacheExtension\CacheProvider\PsrCacheAdapter

After that, you should install a package that provides a psr/cache-implementation. A wide variety of implementations already can be found at: http://php-cache.readthedocs.io/ After installing an adapter with composer, it can be configured to do the caching for this bundle. The CacheBundle allows easy configuration by creating a Symfony service for the cache pool adapter., _(*9)

# config.yml
cache_adapter:
    providers:
        twig_apcu:
            factory: 'cache.factory.apcu'

twig_cache:
    service: cache.provider.twig_apcu

Usage

The default strategy is the IndexedChainingCacheStrategy so you can use directly this code in your Twig templates., _(*10)

{# delegate to lifetime strategy #}
{% cache 'v1/summary' {time: 300} %}
    {# heavy lifting template stuff here, include/render other partials etc #}
{% endcache %}

{# delegate to generational strategy #}
{% cache 'v1/summary' {gen: item} %}
    {# heavy lifting template stuff here, include/render other partials etc #}
{% endcache %}
