Event Sourcing with Laravel
summary
Shows how to implement Event Sourcing and CQRS in Laravel using Spatie’s laravel-event-sourcing package by building an e-commerce demo: commands to aggregate roots produce events stored in a stored_events table, projectors/Reactors update denormalized product and order views, and full replay is supported after dropping views. Setup uses Artisan, migrations and snapshots; the repository (779 stars, 116 contributors) is used in the demo, which registers products, processes purchases, and triggers notifications.
