THIS PACKAGE HAS BEEN SUPERCEDED BY SPATIE/LARAVEL-EVENT-SOURCING
Because the package now does more than just providing projectors, we decided to change the name of the package to spatie/laravel-event-sourcing.
Upgrading from v3 of laravel-event-projector to v1 of laravel-event-sourcing is easy. Take a look at the upgrade guide for laravel-event-sourcing.
Event sourcing for Artisans
��
This package aims to be the entry point to get started with event sourcing in Laravel. It can help you with setting up aggregates, projectors, and reactors.
If you've never worked with event sourcing, or are uncertain about what aggregates, projectors and reactors are head over to the getting familiar with event sourcing section in our docs.
Event sourcing might be a good choice for your project if:
- your app needs to make decisions based on the past
- your app has auditing requirements: the reason why your app is in a certain state is equally as important as the state itself
- you foresee that there will be a reporting need in the future, but you don't know yet which data you need to collect for those reports
If you want to skip to reading code immediately, here are some example apps. In each of them, you can create accounts and deposit or withdraw money.
- Larabank built traditionally without event sourcing
- Larabank built with projectors
- Larabank built with aggregates and projectors

前言 Laravel 的事件系统是一个简单的观察者模式，主要目的是用于代码的解耦，可以防止不同功能的代码耦合在一起。laravel 中事件系统由两部分构成，一个是事件的名称，事件的名称可以是个字符串，例如 event.email，也可以是一个事件类，例如 AppEventsOrderShipped；另一个是事件的 listener，可以是一个闭包，还可以是监听类，例如 AppListenersSe

Swoole扩展还提供了直接操作底层epoll/kqueue事件循环的接口。可将其他扩展创建的socket，PHP代码中stream/socket扩展创建的socket等加入到Swoole的EventLoop中， 否则第三方的$fd如果是同步IO会导致Swoole的EventLoop得不到执行，参考案例。 !> Event模块比较底层，是epoll的初级封装，使用者最好有IO多路复用编程经验。 事
