What problem does it solve?

Go Domain Events provides a structured approach to defining and publishing domain events in Go, enabling decoupled business logic, reliable messaging, and observable workflows.

Core Features & Use Cases

• Domain Event definitions with a BaseEvent and concrete events (e.g. UserCreated, OrderPlaced).
• In-memory Event Bus for multi-handler subscriptions and synchronous publishing.
• Outbox pattern to persist events within a transaction for reliable delivery.
• Idempotency guarantees with processed events tracking to avoid duplicate handling.
• Event Sourcing basics with an append-only event store and replay capability.

Quick Start

Initialize domain events in a Go project and implement an outbox-based, idempotent event publishing flow.
