React各种资源下载（基于Webpack4和最新的React脚手架）

1.首先说下最懒最快的方法，就是拷贝别人成熟的package.json文件中的dependencies、devDependencies和babel中的配置，然后yarn install就行了；

 下面为新下载的脚手架环境下，必须下载的资源 

1.Sass下载（Sass是css的扩展语言）

sass基础用法请查看博客：http://www.ruanyifeng.com/blog/2012/06/sass.html

最新版的React脚手架包含了sass配置和sass-loader，所以只需下载node-sass：

npm install node-sass --save-dev 

 

如果node-sass安装报错，用下述方法：

先 npm install -g cnpm --registry=https://registry.npm.taobao.org下载cnpm

然后用cnpm去安装 cnpm install node-sass --save

 

2.React-router下载

npm install react-router-dom --save

 

3.React-redux下载

yarn add redux

yarn add react-redux

 

4.AntDesign下载

yarn add antd

npm install babel-plugin-import --save-dev

找到package.json,在“babel”中配置AntDesign的CSS预加载

"plugins": [
      [
        "import",
        {
          "libraryName": "antd",
          "libraryDirectory": "es",
          "style": "css"
        }
      ]
    ]

如下图

 

5.axios下载

yarn add axios

 

6.React-transition-group下载

yarn add react-transition-group 

 

7.Redux-thunk下载

yarn add redux-thunk

 

8.styled-components（样式不会全局，可在对应组件生效）

yarn add styled-components

 

9.immutable.js(保护原始state不被篡改)

yarn add immutable

yarn add redux-immutable
