It is intended to make event listener declaration simpler than you could ever imagine. All you need is to use any [PSR-11](https://www.php-fig.org/psr/psr-11/) compatible DI container. Requirements ------------ [](#requirements) - PHP 8.1 - 8.5. Installation ------------ [](#installation) The package could be installed with [Composer](https://getcomposer.org): ``` composer require yiisoft/yii-event ``` General usage ------------- [](#general-usage) ### DI configuration [](#di-configuration) You can find default configuration in the [config directory](config): - [di.php](config/di.php) contains the configuration for the [PSR-14](https://www.php-fig.org/psr/psr-14/) interfaces. - [di-web.php](config/di-web.php) and [di-console.php](config/di-consle.php) contains the configuration for the `Yiisoft\EventDispatcher\Provider\ListenerCollection`. - [params-web.php](config/params-web.php) and [params-console.php](config/params-consle.php) contains parameters for `web` and `console` configurations. All these settings will be used automatically in projects with the [yiisoft/config](https://github.com/yiisoft/config). If you have custom `events` configuration group name, for example `events-api`, redefine it in the `eventsConfigGroup` params key. params.php ``` return [ 'yiisoft/yii-event' => [ 'eventsConfigGroup' => 'events-api', ], ] ``` ### Event configuration example [](#event-configuration-example) The configuration is an array where keys are event names and values are array of handlers: ``` return [ EventName::class => [ // Just a regular closure, it will be called from the Dispatcher "as is". static fn (EventName $event) => someStuff($event), // A regular closure with additional dependency. All the parameters after the first one (the event itself) // will be resolved from your DI container within `yiisoft/injector`. static fn (EventName $event, DependencyClass $dependency) => someStuff($event), // An example with a regular callable. If the `staticMethodName` method contains some dependencies, // they will be resolved the same way as in the previous example. [SomeClass::class, 'staticMethodName'], // Non-static methods are allowed too. In this case `SomeClass` will be instantiated by your DI container. [SomeClass::class, 'methodName'], // An object of a class with the `__invoke` method implemented new InvokableClass(), // In this case the `InvokableClass` with the `__invoke` method will be instantiated by your DI container InvokableClass::class, // Any definition of an invokable class may be here while your `$container->has('the definition)` 'di-alias' ], ]; ``` The dependency resolving is done in a lazy way: dependencies will not be resolved before the corresponding event will happen. ### Configuration checker [](#configuration-checker) To help you with event listener configuration validation there is the `ListenerConfigurationChecker`. It is converting your whole listener config to actual callables at once to validate it. It is intended to be used in development environment or in tests since it is a resource greedy operation in large projects. An `InvalidEventConfigurationFormatException`will be thrown if your configuration contains an invalid listener. Usage example: ``` $checker->check($configuration->get('events-web')); ``` Documentation ------------- [](#documentation) - [Internals](docs/internals.md) If you need help or have a question, the [Yii Forum](https://forum.yiiframework.com/c/yii-3-0/63) is a good place for that.
