ecotone-aggregate

What problem does it solve?

Aggregates are central to domain-driven design, but implementing both state-stored and event-sourced variants with correct identifiers, factory methods, and command wiring can be verbose and error-prone. This skill provides structured patterns and examples to accelerate and standardize aggregate development in Ecotone.

Core Features & Use Cases

• State-stored and event-sourced aggregates with #[Aggregate] and #[EventSourcingAggregate].
• Proper use of #[Identifier] and optional composite keys, including command mapping and event-sourcing patterns.
• Factory methods and repository access wiring to integrate with Ecotone.

Quick Start

Define an aggregate class annotated with #[Aggregate] or #[EventSourcingAggregate], implement an Identifier, and add static creation handlers along with command handlers and event-sourcing handlers to manage state and events.
