webpack3.x+react+react-redux完整实例搭建过程

1.本次搭建过程起初想升级到最新的webpack4.x 发现在extract-text-webpack-plugin 样式打包组件有比较多的问题改成了webpack3.x，于以前老的还是区别很大

安装：cnpm install --save-dev webpack   

          cnpm install --save-dev webpack-dev-server

在配置过程需要一些组件和工具：cnpm install --save-dev style-loader css-loader less less-loader url-loader file-loader img-loader  这些是对css  img less 的处理需要用到的依赖包

对打包后的css 添加前缀：  cnpm install --save-dev postcss-loader autoprefixer autoprefixer-loader

每次重新打包清理对应打包的文件插件： cnpm install --save-dev  clean-webpack-plugin

因为这次是react 自然少不了 react js解析有关的：

cnpm install  --save-dev babel babel-cli babel-core babel-loader babel-preset-es2015 

然后跟react 自身有关的：

cnpm install --save-dev react react-dom react-router  react-router-dom redux redux-logger babel-runtime babel-preset-react

ui框架用的是antd

框架安装：cnpm install --save-dev antd-mobile

按需加载js：cnpm install --save-dev babel-plugin-syntax-dynamic-import

需要的安装依赖基本完毕。。。。。开始操刀

项目结构：

    hot: true,//设置热更新(可在package.json scripts 里设置 npm run xxx);
    port:3000,//设置端口号；
   /* open:true //自动拉起浏览器*/
  }
};

需要注意的地方extract-text-webpack-plugin打包后的css 或者less 里面的backgroud-img  路径会出现错误

加一个 publicPath: '../images/',这样就引用打包后的图片不会报错

package.json  需要的组件依赖版本奉上，里面scripts需要配置根据个人需要添加相应的配置

配置新建文件.babelrc

{

  ]
}

配置新建文件.gitignore

node_modules/
build/

配置新建文件postcss.config.js配置（postcss-loader 设置需要针对手机安卓和iso版本），代码奉上
