在下一节中，我们将会介绍一个新的脚本库，即
React Redux
。该脚本库可以用于快速
地将
Redux
的
Store
添加到上下文并创建容器组件。
React Redux
的
Provider
React Redux
是一个脚本库，它包含的一些工具可以显著降低显式通过上下文传递
Store
的复杂性。该库的作者也是
Dan Abramov
，即
Redux
的作者。
Redux
并不会强制要
求用户使用该库。不过采用
React Redux
之后可以大幅度降低项目代码的复杂度，并且
可以提高用户构建应用程序的工作效率。
为了使用
React Redux
，我们首先必须安装它。它可以通过
npm
（
https://www.npmjs.
com/package/react-redux
）进行安装：
npm install react-redux --save
react-redux
为用户提供了一个组件，可以通过它在上下文中配置用户自己的
Store
，
即
Provider
。我们可以使用
Provider
包装任意
React
元素，该元素的子元素将能够通过
上下文访问
Store
。
与在
App
组件中将
Store
配置成一个上下文变量相反，我们可以确保
App
组件是无状态
的：
import { Menu, NewColor, Colors } from './containers'
const App = () =>
<div className="app">
<Menu />
<NewColor />
<Colors /> ...
