React
服务器端应用
目前为止，我们已经使用
React
构建了一些完全可以在浏览器中运行的小型应用程
序。它们在浏览器中收集数据，并使用浏览器的
storage
存储数据。这是合情合理的，
因为
React
是一个视图层。采用它的主要目的是渲染
UI
。不过，大部分应用程序至少
都存在某种后端，并且我们需要理解如何将应用程序和服务器端整合到一起。
即使用户的客户端应用程序完全依赖于使用云服务作为后端，仍然需要从这些服务中
读取或者发送数据。在
Flux
的影响范围内，有特定的位置处理这些传输，并且还有不
少类库可以帮助用户处理和
HTTP
请求有关的延迟问题。
此外，
React
还支持同构渲染，这意味着它能够兼容浏览器之外的其他平台。同时也
说明我们在页面内容抵达浏览器之前，在服务器端可以对
UI
进行渲染。利用服务器端
渲染，我们可以提高应用程序的性能、可移植性和安全性。
从本章开始，我们将会学习同构性和通用性之间的区别，以及这两个概念和
React
之
间的关系。接下来，将会介绍如何使用通用的
JavaScript
构建一个同构的应用程序。
最后，我们会通过添加一个服务器并首先在服务器端渲染
UI
来改进颜色管理器程序。
同构性和通用性
同构性和通用性这两个术语通常用于描述在客户端和服务器端均可使用的应用程序。
虽然这两个术语在描述相同应用程序时可以互换，但是它们之间存在细微的差别。同

构性应用程序是可以在多个平台上渲染的程序。通用性代码意味着完全相同的代码可
以在多种环境下运行。
