Event Store

This is an event store abstraction for the Phauthentic Event Sourcing Library. It provides a simple interface for storing and retrieving domain events by aggregate, with pluggable backends for different storage engines.

Requirements

• PHP 8.2 or higher

Installation

composer require phauthentic/event-store

Features

• EventStoreInterface – Contract for storing and replaying events by aggregate
• PDO Event Store – SQL-backed store (MySQL, MariaDB, PostgreSQL, SQLite, MS SQL Server)
• In-Memory Event Store – For testing, prototyping, and demos
• EventFactory – Create events from arrays and convert events to arrays
• Serialization – Pluggable serializers for payload and metadata

Quick Start

use Phauthentic\EventStore\Event;
use Phauthentic\EventStore\InMemoryEventStore;
use Phauthentic\EventStore\ReplyFromPositionQuery;

$eventStore = new InMemoryEventStore();

$event = new Event(
    aggregateId: 'order-123',
    aggregateVersion: 1,
    event: 'OrderCreated',
    payload: ['amount' => 99.99],
    createdAt: new \DateTimeImmutable()
);

$eventStore->storeEvent($event);

foreach ($eventStore->replyFromPosition(new ReplyFromPositionQuery('order-123', 1)) as $storedEvent) {
    // Process event...
}
