开发人员使用正确的格式来通信或监听应用中的事件：
const PaymentEvents = {
PAYMENT_CHANGED: "paymentMethodChanged";
// 其他事件
}
之后，可以冻结对象，防止运行时更改对象结构、添加或删除对象的属性。
当在同一个视图中有多个微前端通过事件相互通信时，我们必须确保所有事件都被相关的
微前端捕获。假设在同一个视图中有
3
个微前端
，其中两个立即加载，而第
3
个由于网络
问题需要等待一段时间。当前两个微前端发出事件时，第
3
个微前端在加载时无法捕获发
生的任何事件。一种可能的解决方案是在应用容器中创建一个事件缓冲区，并在第
3
个微
前端完全加载时重放它们。这个事件缓冲区用于监控每个微前端的状态，将所有事件收集
到一个数组或类似的数据结构中，然后将所有事件按需重放给一个或多个微前端，而不是
把事件列表中的全部事件重放给每个微前端（这样做可能会导致内部状态不匹配）。在同
一个视图中有多个微前端时，需要认真思考如何处理故障或部分故障的状态。虽然很烦
琐，但我们必须考虑这些情况，因为正如

CTO Werner Vogels
所说，“不要心存侥
幸，失败随时都在”。

项目演变
我们不想创建一个只能在短期内运转的项目，而是希望创建一个可以随着时间的推移长
期运行的产品。当组织目标发生变化时，开发团队无须从头再来。那么，让我们一起探
讨一下如何让这个项目长期发展，以及我们如何在不同的子域之间创建一个连贯、一致
的实现。
