Event Sourcing in Laravel
summary
A runnable demo shows an app called Larabank built with the laravel event sourcing package, storing every change in a stored events table and rebuilding views via projectors; a replay command reconstructs the accounts projection and a later-added transaction-count projector without changing data. Reactors fire only on original events (replays skip side effects). Aggregates reconstitute from past events and enforce rules — e.g. three overdraw attempts below -5000 persist a loan-proposed event and trigger a mail.
