library zf-annotations

alex-oleshkevich/zf-annotations

ZF2 module for annotated configuration.

Annotations for Zend Framework.

This module provides "configuration via annotation" support for Zend Framework. Out of the box it allows to define routes, service and all the ServiceManager-based implementations (as controllers, view helpers, etc).
The goal of this project is to get rid of large configuration arrays in application configs., _(*1)

, _(*2)

Requirements

• PHP >= 7.0.0

Please, note

1. if you want to use Zend libraries from Zend Framework 2, use ~1.0 versions. Branch ~2.0 supports future versions of Zend Framework and may not be compatible with ZF 1., _(*3)

2. Since version 2.3 the module does not use zendframework/zend-code as a backend and use doctrine/annotations directly. See doctrine documentation for more details and options., _(*4)

Deprecations

1. Config option "annotations" deprecated in favor of "namespaces".

Installation

Require via composer

composer require alex-oleshkevich/zf-annotations

Enable it in application.config.php

return array(
    'modules' => array(
        // other modules
        'ZfAnnotation'
    ),
    // other content
);

Configuration:

array(
    'zf_annotation' => array(
        // in which modules to search annotated classes
        'scan_modules' => array(),

        // DEPRECATED AND REMOVED IN 2.3
        // here listed all annotations supported by the module
        // add your own here
        'annotations' => array(
            'ZfAnnotation\Annotation\Route',
            // ...
        ),

        /*
         * IMPORTANT NOTE:
         * The given directories should NOT be the directory where classes of the namespace are in, 
         * but the base directory of the root namespace. The AnnotationRegistry uses a namespace to directory separator
         * approach to resolve the correct path.
         */
        'namespaces' => array(
            'My\Annotation' => '/path/to/annotations'
        ),

        // listeners to events emitted by parser. 
        // they process class annotations and transforms them into config values
        // add your own here.
        'event_listeners' => array(
            'ZfAnnotation\EventListener\RouteListener',
            // ...
        ),
        // if not null, supplied directory would used for cache to speed up parsing
        'cache' => '/path/to/cache/dir',
        // if true, will ignore cached data and always return a fresh one.
        'cache_debug' => false
    )

Performance

This module is pretty fast, but anyway, parsing of lots of files on each request takes time.
The module subscribes to ModuleEvent::EVENT_MERGE_CONFIG and scans every time its is triggered. If you have option module_listener_options.config_cache_enabled enabled, annotation parser will not do parsing unless you set config_cache_enabled to false or remove a cache file. More info about caching here., _(*5)
