Installation

This bundle can be installed using composer:

composer require openclassrooms/service-proxy-bundle
or by adding the package to the composer.json file directly.

{
    "require": {
        "openclassrooms/service-proxy-bundle": "*"
    }
}

After the package has been installed, add the bundle to the AppKernel.php file:

// in AppKernel::registerBundles()
$bundles = array(
    // ...
    new OpenClassrooms\Bundle\ServiceProxyBundle\OpenClassroomsServiceProxyBundle(),
    // ...
);

⚠️ The usage of cache capabilities requires the installation of the openclassrooms/doctrine-cache-extension-bundle.
See the openclassrooms/doctrine-cache-extension-bundle installation guidefor more details.

Usage

Cache

Use the Cache annotation.
See Service Proxy Cache for more details.

<?php

namespace A\Namespace;

use OpenClassrooms\ServiceProxy\Annotations\Cache;

class AClass
{
    /**
     * @Cache
     */
    public function aMethod()
    {
        // do things
    }
}

Using default cache provider

# app/config/config.yml

doctrine_cache:
    providers:
        a_cache_provider:
            type: array

openclassrooms_service_proxy: 
    default_cache: doctrine_cache.providers.a_cache_provider    

<!-- services.xml -->
<service id="a_service" class="A\Namespace\AClass">
    <tag name="openclassrooms.service_proxy"/>
</service>

Using specific cache provider

<!-- services.xml -->
<service id="a_service" class="AClass">
    <tag name="openclassrooms.service_proxy" cache="doctrine_cache.providers.a_cache_provider"/>
</service>

Performance

Autoloader

The usage of a proxy require a lot of I/O. See Ocramius\ProxyManager Tunning for production.
It's possible to specify the environments where the proxy autoloader is used.

openclassrooms_service_proxy:
    production_environments: ['prod', 'stage'] # default : ['prod']
    

Cache Warmup

The bundle uses the Symfony cache warmup to dump the proxies files.

Full configuration

openclassrooms_service_proxy:
    # the directory where the proxy are written
    cache_dir : "/a/path/to/the/cache/directory" # default: %kernel.cache_dir% 
    
    # the default cache provider (optional)
    default_cache: doctrine_cache.providers.a_cache_provider # default: null
    
    # the Symfony environments where the proxy autoloader is used
    production_environments: ['prod', 'stage'] # default : ['prod']
