AWD Event Sourcing library
==========================

[](#awd-event-sourcing-library)

This is a PHP library designed to simplify the implementation of Event Sourcing patterns in your applications. It provides a robust set of tools and abstractions to manage aggregates, events, event storage, and snapshots, enabling you to build scalable, maintainable, and auditable systems.

What is Event Sourcing?
-----------------------

[](#what-is-event-sourcing)

Event Sourcing is a design pattern where changes to an application's state are captured as a sequence of events. Instead of storing only the current state, the application maintains a history of all events that have occurred. This approach offers several advantages, including:

- **Auditability:** Every state change is recorded, providing a complete history.
- **Scalability:** Events can be processed asynchronously or in parallel.
- **Reconstructability:** Past states can be rebuilt by replaying events.

Features
--------

[](#features)

- **Aggregates:** Manage domain entities with built-in support for event sourcing.
- **Events:** Define and handle domain events easily.
- **Event Store:** Persist and retrieve events from a configurable storage backend.
- **Repositories:** Simplify loading and saving aggregates.
- **Snapshots:** Optimize performance by storing snapshots of aggregate states.

Installation
------------

[](#installation)
