Event-Driven Clean Architecture

Welcome to Event-Driven Clean Architecture! In complex systems, parts often need to react to things happening elsewhere without being tightly coupled.

This lesson explores how to integrate event-driven patterns into your Clean Architecture, using domain events to enhance decoupling and scalability, while strictly adhering to the Dependency Rule.

A Domain Event is something that happened in the domain that domain experts care about. It's an immutable fact, a record of an occurrence, like 'Order Placed' or 'User Registered'.

• They represent a change in the state of the domain.
• They are typically named in the past tense (e.g., OrderPlaced).
• They should be simple data structures, containing only relevant information about the event.
