react + webpack 多页面搭建

一、利用 creat-react-app 新建一个react单页面应用。

cnpm i -g create-react-app

create-react-app demo

cd demo

npm start

可以看到下面页面

三、修改index.js内容为：

import React from 'react';

import ReactDOM from 'react-dom';

import './index.scss';

class Login extends React.Component{

    constructor() {

        super();

        this.state = {

        }

    }

    componentDidMount(){

    }

    render() {

        return (

            <div className="login">

                22

              </div>

        )

    }

}

ReactDOM.render(

    <Login/>,

    document.getElementById('app')

);

四、删除src下面的registerServiceWorker.js（该文件用于构建pwa应用用的，暂时我们用不了）和 logo.svg文件（不想处理图片文件）和 App.test.js(用于测试用的)。

现在src/下面有四个文件。接下来，在src下面新建自己需要的文件夹，分别将原来的四个文件拷贝进文件夹内。文件目录如下：

五、修改public/index.html内容为：

<!doctype html>

<html lang="en">

  <head>

    <meta charset="utf-8">

    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

    <meta name="theme-color" content="#000000">

    <title>React App</title>

  </head>

  <body>

    <noscript>

      You need to enable JavaScript to run this app.

    </noscript>

    <div id="root"></div>

  </body>

</html>

六、开始install webpack和配置webpack

1.安装依赖。将package.json文件用下面的文件替代

{

  "name": "demo",

  "version": "0.1.0",

  "private": true,

  "dependencies": {

    "react": "^15.6.1",

    "react-dom": "^15.6.1"

  },

  "devDependencies": {

    "babel-core": "^6.26.0",

    "babel-loader": "^7.1.2",

    "babel-preset-es2015": "^6.24.1",

    "babel-preset-react": "^6.24.1",

    "clean-webpack-plugin": "^0.1.16",

    "css-loader": "^0.28.7",

    "extract-text-webpack-plugin": "^3.0.0",

    "file-loader": "^1.0.0",

    "glob": "^7.1.2",

    "html-webpack-plugin": "^2.30.1",

    "postcss-loader": "^2.0.6",

    "style-loader": "^0.18.2",

    "url-loader": "^0.5.9",

    "webpack": "^3.5.6",

    "webpack-dev-server": "^2.8.1"

  },

  "scripts": {

    "start": "webpack-dev-server --open",

    "build": "webpack"

  }

}

2.删除当前目录中的node_modules，然后重新在控制台执行

npm i

3.在根目录下也就是／demo下新建一个webpack.config.js文件,写入如下代码

const webpack = require('webpack');

const glob = require('glob');

const path = require('path');

const HtmlWebpackPlugin = require('html-webpack-plugin');

const ExtractTextPlugin = require('extract-text-webpack-plugin');

const CleanWebpackPlugin = require('clean-webpack-plugin');

let cssExtract = new ExtractTextPlugin('assets/css/reset.css');

let sassExtract = new ExtractTextPlugin('assets/css/[name].[chunkhash:6].css');

const env=process.argv[2];

let dnsPath='';

if(env==='pro'){

    dnsPath=''

}else if(env==='stg'){

    dnsPath=''

}else{//本地

    dnsPath='/finance/scan-to-pay'

}

const webpackConfig = {

  entry: {},

  output:{

    path:path.resolve(__dirname, 'dist'),

    filename:'assets/js/[name].[chunkhash:6].js',

    publicPath: '/'

  },

  devServer: {

    host: "172.16.10.70",

    inline: true,

    port: 8181,

    // proxy: {

    //   '/financegateway': {

    //     target: '',

    //     changeOrigin: true

    //   }

    // }

    proxy: [{

      context: ['/financegateway', '/uploadimage', '/pointgate'],

      target: '',

      changeOrigin: true

    }]

  },

  module:{

    rules:[

      {

        test:/\.js?$/,

        exclude:/node_modules/,

        loader:'babel-loader',

        query:{

          presets:['@babel/preset-env','@babel/preset-react']

        }

      },

      {

        test: /\.css$/,

        use: cssExtract.extract({

          use: ['css-loader', 'postcss-loader']

        })

      },

      {

        test: /\.scss$/,

        loader: sassExtract.extract({

          use: ['css-loader', 'postcss-loader', 'sass-loader']

        })

      },

      // {

      //   test: /\.(png|jpg|jpeg|gif)$/,

      //   use: [

      //     {

      //       loader: 'url-loader?limit=8192&name=assets/imgs/[name][hash:6].[ext]'

      //     }

      //   ]

      // }

      {

        test: /\.(png|jpg|jpeg|gif|svg)$/,

        use: [

          {

            loader: 'file-loader',

            options: {

              name() {

                return 'assets/imgs/[hash:6].[ext]'

              },

              publicPath: '/'

            }

          }

        ]

      }

    ]

  },

  plugins: [

    cssExtract,

    sassExtract,

    new CleanWebpackPlugin(

      ['dist'],　

      {

        root: __dirname,    　　　　　　　　　　

        verbose: true,    　　　　　　　　　　

        dry:   false    　　　　　　　　　　

      }

    )

  ],

};

// 获取指定路径下的入口文件

function getEntries(globPath) {

  const files = glob.sync(globPath),

   entries = {};

  files.forEach((filepath)=> {

    const path = filepath.replace(/\/index.js/, ''); // 获取文件路径

    let name = path.replace(/src\//, ''); // 文件路径去除src目录

    entries[name] = './' + filepath;

  });

  return entries;

}

const entries = getEntries('src/**/index.js');

// 循环入口文件

Object.keys(entries).forEach((name)=> {

    webpackConfig.entry[name] = entries[name];

    const plugin = new HtmlWebpackPlugin({

      filename: `${name}/index.html`,

      template: `src/${name}/index.html`,

      inject: true,

      chunks: [name]

    });

    webpackConfig.plugins.push(plugin);

})

module.exports = webpackConfig;

4.postcss.config.js

module.exports = {

    plugins: [require('autoprefixer')({

        overrideBrowserslist: ["last 5 versions"] // 所有浏览器兼容到最后5个版本

    })]

}
