This time I will bring you how to deal with large files packaged by webpack and how to deal with large files packaged by webpack. What are the precautions?The following is a practical case, let's take a look.
Optimization comparison:
Before optimization: index.html introduces a main.js file with a size of more than 2M.
After optimization: index.html introduces main.js, commons.js, charts.js, and other.js. In order to achieve the purpose of dividing main.js equally. Each file is controlled within 300k. (If you are happy, 100k is no problem)
A bunch of libraries and tools used:
vue, webpack, babel, highcharts, echarts, jquery, html2canvas****** I will omit some m codes here
Problem:
After using webpack in the development environment, I found a single js file 5m.
The production environment is reduced to 2m with the help of vue-cli's webpack configuration.
Solution:
Search various solutions: require.ensure, require dependency, multiple entries, commonsChunkPlugin****Here are some solutions to save effort
There are too many solutions similar to the ones below, but they all fail to achieve the expected results
entry:{ main:'xxx.js', chunks:['c1', 'c2'], commons:['jquery', 'highcharts', 'echarts','d3', 'xxxxx.js'] } plugins:{ new commonsChunkPlugin({ name:'commons', minChunks:2 }) }
Optimal solution:
entry:{ main:'xxx.js' } plugins:{ new commonsChunkPlugin({ name:'commons', minChunks:function(module){ // 下边return参考的vue-cli配置 // any required modules inside node_modules are extracted to vendor return ( module.resource && /\.js$/.test(module.resource) && module.resource.indexOf( path.join(dirname, '../node_modules') ) === 0 ) } }) , // 以下才是关键 new commonsChunkPlugin({ name:'charts', chunks:['commons'] minChunks:function(module){ return ( module.resource && /\.js$/.test(module.resource) && module.resource.indexOf( path.join(dirname, '../node_modules') ) === 0 && ['jquery.js', 'highcharts.js','echarts'].indexOf( module.resource.substr(module.resource.lastIndexOf('/')+1).toLowerCase() ) != -1 ) } }) // 如果愿意,可以再new 一个commonsChunkPlugin }

Vue是一款优秀的JavaScript框架,它可以帮助我们快速构建交互性强、高效性好的Web应用程序。Vue3是Vue的最新版本,它引入了很多新的特性和功能。Webpack是目前最流行的JavaScript模块打包器和构建工具之一,它可以帮助我们管理项目中的各种资源。本文就为大家介绍如何使用Webpack打包和构建Vue3应用程序。1.安装Webpack

区别:1、webpack服务器启动速度比vite慢;由于vite启动的时候不需要打包,也就无需分析模块依赖、编译,所以启动速度非常快。2、vite热更新比webpack快;vite在HRM方面,当某个模块内容改变时,让浏览器去重新请求该模块即可。3、vite用esbuild预构建依赖,而webpack基于node。4、vite的生态不及webpack,加载器、插件不够丰富。

随着Web开发技术的不断发展,前后端分离、模块化开发已经成为了一个广泛的趋势。PHP作为一种常用的后端语言,在进行模块化开发时,我们需要借助一些工具来实现模块的管理和打包,其中webpack是一个非常好用的模块化打包工具。本文将介绍如何使用PHP和webpack进行模块化开发。一、什么是模块化开发模块化开发是指将程序分解成不同的独立模块,每个模块都有自己的作

在vue中,webpack可以将js、css、图片、json等文件打包为合适的格式,以供浏览器使用;在webpack中js、css、图片、json等文件类型都可以被当做模块来使用。webpack中各种模块资源可打包合并成一个或多个包,并且在打包的过程中,可以对资源进行处理,如压缩图片、将scss转成css、将ES6语法转成ES5等可以被html识别的文件类型。

Webpack是一款模块打包工具。它为不同的依赖创建模块,将其整体打包成可管理的输出文件。这一点对于单页面应用(如今Web应用的事实标准)来说特别有用。

配置方法:1、用导入的方法把ES6代码放到打包的js代码文件中;2、利用npm工具安装babel-loader工具,语法“npm install -D babel-loader @babel/core @babel/preset-env”;3、创建babel工具的配置文件“.babelrc”并设定转码规则;4、在webpack.config.js文件中配置打包规则即可。

web前端打包工具有:1、Webpack,是一个模块化管理工具和打包工具可以将不同模块的文件打包整合在一起,并且保证它们之间的引用正确,执行有序;2、Grunt,一个前端打包构建工具;3、Gulp,用代码方式来写打包脚本;4、Rollup,ES6模块化打包工具;5、Parcel,一款速度极快、零配置的web应用程序打包器;6、equireJS,是一个JS文件和模块加载器。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
