Discover how to decouple your application logic using Event-Driven Architecture (EDA) in two of the most popular PHP frameworks: Laravel and Symfony.
Why Event-Driven Architecture?
In traditional applications, components tend to become tightly coupled. For example, a UserController might handle user registration and send a welcome email. This kind of logic tangling is a common bottleneck for scalability and maintainability.
Event-Driven Architecture (EDA) solves this by decoupling concerns. You emit events when something happens (e.g. UserRegistered), and other parts of the system listen for those events to take action (e.g., send an email, log activity).
This approach offers:
Loose coupling
Better separation of concerns
Scalability and extensibility
Optional async processing
Event-Driven Architecture: Key Concepts
Event: A message that signals something has happened (e.g., UserRegistered, OrderPlaced).
Producer/Dispatcher: Component that emits an event.
