我在Node.js
中构建了中型Web应用程序。起初,我没有计划它会增长到中等大小,并且不知道它是否会被使用。现在,当客户的用户开始使用它时,需要另外两个功能:
由于到目前为止我使用了服务器端模板(即我的所有API
路由都使用HTML
进行了回复),我需要做出巨大更改以支持API
以{{1}进行响应仅适用于移动应用,所以我决定对整个应用进行重构,以同时支持这两个方面。
通过阅读一些在线资源(即Single Page App Book)并比较可用的JavaScript框架(Angular vs Backbone vs React vs Ember),我得出了以下结论。我的问题是,我错过了什么吗?所以,这就是我计划如何扩展我的网络应用程序:
JSON
React
路由仍将使用API
回复,而HTML
将server-rendered使用服务器端HTML
,但这些React UI组件将也包括在浏览器端,它将支持单页面应用程序功能。React
REST
,可能基于JSON API
服务器标准与单页面应用程序和移动Web应用程序进行通信。API
路由(API
响应页面 - API
,以及数据 - HTML
)将使用JSON
路由器完成,该路由器将执行< em> controllers (服务器组件),用于封装与数据访问层(服务器组件)的数据组合操作。Express
个模型组成。 由于这需要更长的时间来实现和重构它,我想确保我在正确的轨道上。我在这里错过了什么吗?
答案 0 :(得分:1)
如果包含助焊剂图案,它将使您的应用程序更易于构建和维护。我建议你看看一些初学者项目并选择一个赞美你自己风格的项目。以下是https://github.com/calitek/ReactPatterns React.14 / ReFluxSuperAgent的示例。这可能看起来很复杂,但这种模式可以很好地分离关注点和灵活性。
