架构特征
可部署性（5 分）
因为每个微前端都是单一的
HTML
页面或
单页应用，所以可以很容易地将产品部署在
云存储或应用服务器上，并在这些服务器之前部署
CDN
节点
。许多前端开发人员已经
使用这一方法多年，用于交付
We
b
应用。另外，当使用多
CDN
策略时，无论
CDN
提
供商出现任何问题，我们都可以确保将内容正常地提供给用户。
模块化（2 分）
这个架构的模块化程度一般。虽然有一定程度的模块化和可复用性，但更多的是在代码
层面共享组件或库，而在功能层面的共享较少。比如，负责开发目录的微前端团队不太
可能与另一个微前端团队共享代码。此外，因要实现新功能而不得不将一个纵向拆分的
微前端分割成两个或更多的部分时，由于它被设计成一个独特的逻辑单元，因此需要更
大的成本来解耦其中所有的共享依赖关系。
简单性（4 分）
这种方法的主要目的是减少团队的心智负担，通过前端开发人员的实践培育业务领域的
专家，这就体现了这种架构的简单性。接受这种架构不需要太多思维方式上的转变，也
没有太多新技术需要学习。对于前端开发人员来说，从
single-spa
或
Module Federation
开始接入微前端的成本应该是最小的。
可测试性（4 分）
与单页应用相比，这种方法在
App shell
的端到
端测试方面有一些弱点。然而，除了极
端情况，测试纵向拆分的微前端仍然可以复用现有的单元测试、集成测试或端到端测试
的经验。
性能（4 分）
你可以共享纵向拆分架构的公共库，尽管这需要团队在一定程度上保持协同。由于采用
这种方法的架构不太可能有数百个微前端，因此可以很容易地创建一种部署策略，将公 ...
