This article mainly introduces the detailed explanation of webpack express multi-page site development
After learning the webpack entry-level tutorial, I feel that it may be specially tailored for single-page applications, such as webpack react, webpack vue, etc., can solve the dependency loading and packaging problems of various resources. Even css is packaged in js and dynamically added to the dom document.
So if we want an ordinary web site with multiple pages, css is independent, and js loading requires modules?

package.json #项目配置
webpack.config.js #webpack配置Development page
Create the index.js file in the src/js/page directory and the index.html file in the src/view directory . The entry js corresponds to the template file name.
index.html The content is as follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>首页</title>
<!--
描述：head中无需再引入css以及facicon，webpack将根据入口JS文件的要求自动实现按需加载或者生成style标签
-->
</head>
<body>
<!--
描述：body中同样无需单独引入JS文件，webpack会根据入口JS文件自动实现按需加载或者生成script标签，还可以生成对应的hash值
-->
</body>
</html>is such a simple HTML template. Do not introduce any CSS and JS. It can be automatically introduced for us through webpack packaging.
index.js content is as follows:
//引入css
require("../../css/lib/base.css");
require("../../css/page/index.scss");
$('body').append('<p class="text">index</p>');page1.html:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>page1</title> </head> <body> </body> </html>
page1.js:
//引入css
require("../../css/lib/base.css");
require("../../css/page/page1.less");
$('body').html('page1');webpack configuration (I use the express framework, Others are based on personal needs)

You can see that in addition to retaining the content in the original template, the generated file also uses the entry file The definition of index.js, automatic addition requires the introduction of CSS and JS files, as well as favicon, and the corresponding hash value is also added.
Two questions
How does webpack automatically discover the entry file and configure the corresponding template
How to directly deal with styles and script automatic introduction issues

The above are all configurations in mac osx system, the win7 path may be different
glob: What is parsed here is different:
But the final requirement is
entries:
{
index: [ './src/template/index.js' ],
page1: [ './src/template/page1.js' ]
}
pages:
[ 'index', 'page1' ]You need to change it accordingly according to the configuration of your personal computer

VUE3入门教程：使用Webpack进行打包和构建Jun 15, 2023 pm 06:17 PMVue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
vite和webpack的区别是什么Jan 11, 2023 pm 02:55 PM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。

vue webpack可打包哪些文件Dec 20, 2022 pm 07:44 PM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是什么？详解它是如何工作的？Oct 13, 2022 pm 07:36 PMWebpack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。
webpack怎么将es6转成es5的模块Oct 18, 2022 pm 03:48 PM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。
