js和html的压缩

注：高版本webpack生产环境下会自动压缩 js代码和html代码

const { resolve } = require('path')
const HtmlWebpackPlugin = require("html-webpack-plugin");
module.exports = {
    entry: './src/js/index.js',
    output: {
        filename: 'js/built.js',
        path: resolve(__dirname, 'build')
    },
    plugins: [
        new HtmlWebpackPlugin({
            template: './src/index.html',
            minify:{
                //移除空格
                collapseWhitespace:true,
                //移除注释
                removeComments:true
            }
        })
    ],
      //生产环境下会自动压缩 js代码
    mode: 'production'
}
