Components

Content Negotiation and Template Resolver Listener

Symfony Event Listener which works out right response content type based on "Accept" header.

# app/config/services.yml

parameters:

    priorities: [ 'application/json', 'text/html' ]

services:
        
    listener.template.resolver:
        class: FlyingColours\CommonBundle\Listener\TemplateResolverListener
        arguments: [ "@sensio_framework_extra.view.guesser" ]
        tags:
            - { name: kernel.event_listener, event: kernel.controller, method: onKernelController }
    
    listener.content.negotiation:
        class: FlyingColours\CommonBundle\Listener\ContentNegotiationListener
        arguments:
            $priorities: "%priorities%"
        tags:
            - { name: kernel.event_listener, event: kernel.view, method: onKernelView }

Persistent Memcached

If you ever experienced problem described here then you want to use this class instead of default Memcached.

# app/config/services.yml

services:

    memcached:
        class: FlyingColours\CommonBundle\Service\PersistentMemcached
        arguments:
            persistent_id: "%session_prefix%"
        calls:
            - [ addServer, [ "%memcached_host%", "%memcached_port%" ]]

    session.handler.memcached:
        class:     Symfony\Component\HttpFoundation\Session\Storage\Handler\MemcachedSessionHandler
        arguments: [ "@memcached", { prefix: "%session_prefix%", expiretime: "%session_expire%" }]

CORS Listener

See this page for details

# app/config/services.yml

services:

    listener.cors.headers:
        class: FlyingColours\CommonBundle\Listener\CorsHeadersListener
        tags:
            - { name: kernel.event_listener, event: kernel.response, method: onKernelResponse }

Also if you want to implement quick OPTIONS handler without creating special action or controller, you can add additional tag for kernel.request event.

# app/config/services.yml

services:

    listener.cors.headers:
        class: FlyingColours\CommonBundle\Listener\CorsHeadersListener
        tags:
            - { name: kernel.event_listener, event: kernel.response, method: onKernelResponse }
            - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest, priority: 33 }

To use in memory cache just use it in same way as memcached implementation:

services:
    cache.in_memory:
        class: FlyingColours\CommonBundle\Service\InMemoryCache
