章
这两种情况都不会有任何扩展性问题。如果你的团队有更强的前端技能，强烈建议使用客
户端路由，这样基于后端配置使用客户端路由就自然而然了。
这些路由方法都不是互斥的。正如你将在本书后面看到的那样，可以把
CDN
和源服务器
（或者客户端和
CDN
）结合起来使用
。重要的是我们希望如何在应用中使用路由，这一决
定将影响我们如何开发微前端应用。

微前端通信
在理想情况下，所有的微前端都是自给自足的，因此微前端不需要相互通信。但现实不尽
如人意，因为有时候需要把用户的交互信息通知给其他微前端，尤其是当我们在同一个页
面上使用多个微前端时。
在同一个页面上有多个微前端时，要为用户提供一致、连贯的用户界面会很复杂。同样，
在不同团队负责的微前端之间进行通信也很复杂。请记住，每个微前端都不应该知晓同一
页面上的其他微前端，否则，我们就违反了独立部署的原则。
在这种情况下，有几种技术选型可以通知其他微前端有事件发生。我们可以在每个微前端
中注入
事件总线
（
eventbus
）
，这种机制通过在总线上发送事件让解耦的组件之间能够相互
通信，一个微前端发送的事件会通知到每个微前端。如果某个微前端对所发送的事件感兴
趣，那么它可以监听事件的触发并做出反应和处理，如图
