这里使用 html-webpack-plugin 插件压缩 html 文件。
1.文件结构
2.代码
index.html
<!DOCTYPE html> <html lang="en"> <head><meta charset="UTF-8"><title>webpack</title> </head> <body> <!--这里是注释--> <h5>webpack</h5> </body> </html>
index.js
//第二种方式: 全部js兼容性处理 // import '@babel/polyfill' const add = (x, y)=> {return x + y; } console.log(add(1, 2));const promise = new Promise((resolve)=>{setTimeout(()=>{console.log('定时器执行完毕')resolve()},1000) }) console.log("promise:",promise)
webpack.config.js
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",//压缩 html 代码
minify: {//移除空格collapseWhitespace: true,//移除注释removeComments: true}})],//生产环境下回自动压缩js代码mode: "production"
}
3.打包
$ webpack
end~
