webpack2使用ch3-自动化生成.html和内部引入的js自动更改

const webpack = require(‘webpack‘),
      htmlWebpackPlugin = require(‘html-webpack-plugin‘),
      path = require(‘path‘);

module.exports = {
    entry: {
      main: ‘./src/script/main.js‘,
      a: ‘./src/script/a.js‘
    },
    output: {
        path: path.resolve(__dirname, ‘./dist‘),
        filename: ‘js/[name]-[chunkhash].js‘
    },
    plugins: [  //初始化插件
        new htmlWebpackPlugin({
            filename: ‘index-[hash].html‘,
            template: ‘index.html‘, //以根index.html为模板生成
            inject: ‘head‘, //指定插入js的位置 或body
        })
    ]
};
