Built for developers who value simplicity, testability, and performance, it allows you to decouple your application logic using event-driven architecture without the overhead of heavier frameworks. Whether you're working with a microservice, a modular monolith, or a full-stack application, Slick Event integrates seamlessly and gives you the tools to manage domain events, listeners, and dispatchers with ease. --- ### โœจ Features [](#-features) - โœ… **PSR-14 compliant**: Follows the PHP-FIG Event Dispatcher standard for interoperability. - ๐Ÿ” **Synchronous event dispatching** with support for multiple listeners. - โš™๏ธ **Simple and intuitive API** for registering and dispatching events. - ๐Ÿงช **Spec-driven development** using PHPSpec ensures reliability and clean design. - ๐Ÿงฉ **Framework-agnostic**: Use it in any PHP project, regardless of framework. This package follows: - [PSR-2: Coding Style Guide](https://www.php-fig.org/psr/psr-2/) - [PSR-4: Autoloading Standard](https://www.php-fig.org/psr/psr-4/) - [Semantic Versioning 2.0.0](https://semver.org) --- ๐Ÿš€ Installation -------------- [](#-installation) Install via Composer: ``` composer require slick/event ``` --- ๐Ÿงฉ Basic Usage ------------- [](#-basic-usage) ``` use Slick\Event\EventDispatcher; use Slick\Event\Event; $dispatcher = new EventDispatcher(); $dispatcher->listen(SomeEvent::class, function (SomeEvent $event) { // Handle event }); // Dispatch event $dispatcher->dispatch(new SomeEvent()); ``` --- โœ… Usage ------- [](#-usage) ### 1. Define an Event and a Listener [](#1-define-an-event-and-a-listener) ``` namespace App\Domain\Event; final class UserWasRegistered { public function __construct(public string $email) {} } ``` ``` namespace App\Application\Listener; use App\Domain\Event\UserWasRegistered; use Slick\Event\Application\Attribute\AsEventListener; #[AsEventListener(event: UserWasRegistered::class)] final class SendWelcomeEmail { public function __invoke(UserWasRegistered $event): void { // Send welcome email to $event->email } } ``` --- ### 2. Set Up the ListenerProvider and Dispatcher [](#2-set-up-the-listenerprovider-and-dispatcher) ``` use Slick\Event\Infrastructure\AttributeListenerResolver; use Slick\Event\Infrastructure\AttributeListenerProvider; use Slick\Event\EventDispatcher; use App\YourContainer; $container = new YourContainer(); // PSR-11 compliant $resolver = new AttributeListenerResolver( __DIR__.'/src/Application/Listener', $container ); $provider = new AttributeListenerProvider($resolver); $dispatcher = new EventDispatcher($provider); ``` --- ### 3. Dispatch the Event [](#3-dispatch-the-event) ``` $dispatcher->dispatch(new UserWasRegistered('user@example.com')); ``` All listeners discovered via `#[AsEventListener]` will be automatically executed. --- โœ… Testing --------- [](#-testing) We use [PHPSpec](http://www.phpspec.net/) for unit testing. Run tests with: ``` vendor/bin/phpspec run ``` or ``` composer test ``` --- ๐Ÿค Contributing -------------- [](#-contributing) Please read our [CONTRIBUTING.md](CONTRIBUTING.md) guidelines. --- ๐Ÿ›ก Security ---------- [](#-security) If you discover a security vulnerability, please email us at **** instead of using the issue tracker. --- ๐Ÿ™ Credits --------- [](#-credits) - [Slick Framework Team](https://github.com/slickframework) - [All Contributors](https://github.com/slickframework/event/graphs/contributors) --- ๐Ÿ“„ License --------- [](#-license) This package is open-source software licensed under the [MIT License](LICENSE). ### Health Score 48 โ€” FairBetter than 94% of packages Maintenance76 Regular maintenance activity Popularity20 Limited adoption so far Community7 Small or concentrated contributor base Maturity74 Established project with proven stability Bus Factor1 Top contributor holds 100% of commits โ€” single point of failure How is this calculated?**Maintenance (25%)** โ€” Last commit recency, latest release date, and issue-to-star ratio.
