This package is auto-updated.

OcraServiceManager is a Zend Framework 2 Module that decorates Zend\ServiceManager\ServiceManager to allow tracking dependencies between services.

It integrates with ZendDeveloperTools to provide aid in debugging what is happening between your dependencies, allowing you to produce dependency graphs such as the following one:

Example Dependency Graph generated by OcraServiceManager

It is heavily tested and supports proxying of any possible object type.

If you don't know what proxies are, you can read my article about service proxies and why we need them.

The recommended way to install ocramius/ocra-service-manager is through composer:

php composer.phar require ocramius/ocra-service-manager

You can then enable this module in your config/application.config.php by adding OcraServiceManager to the modules key:

// ...
    'modules' => array(
        // add OcraServiceManager and ZDT...
        // ... and then your stuff

Please note that you need to enable service manager logging and the ZendDeveloperTools toolbar to actually see something working.


Following config keys are provided by default, but you can change them as you want. You can drop a file ocra-service-manager.local.php into your config/autoload directory to enable or disable logging of your service manager instances:

return array(
    'ocra_service_manager' => array(
        // Turn this on to disable dependencies view in Zend Developer Tools
        'logged_service_manager' => true,

Please note that logging is enabled by default

Testing and Contributing

Please refer to the contents of .travis.yml to see how to test your patches against OcraServiceManager.

Any pull requests will be accepted only if:

  • code coverage on newly introduced code is >= 90% (use @coversNothing on integration tests, please)
  • coding standard complies with PSR-2
  • generally tries to respect object calisthenics

Known limitations:

  • Installing the module itself won't allow tracking the first service-manager events in your application. If you need to have that working, you will need to override the implementation of Zend\Mvc\Application::init()
  • If you have an authorization module enabled, be aware that OcraServiceManager registers a new controller 'OcraServiceManager\Controller\YumlController' as well as a new route 'ocra_service_manager_yuml'. You will need to enable access to both these in development mode in order to see the dependencies diagram.
