I am learning webpack recently, and I am following the course to create a single-page application. I will record it here. This part mainly talks about how to configure the webpack environment and the configuration of webpack dev. The record is rough and will be updated later. This article mainly introduces you to the basic configuration tutorial of the Vue+webpack project. Friends who need it can refer to it. I hope it can help you.
1. Development environment: vscode, node.js, vue.js, webpack
If you want to install node.js yourself, you can refer to the novice tutorial
The IDE used is VScode
2. Project initialization
Shortcut key ctrl+` to open the vscode console
vscode interface
2.1 Install webpack vue vue-loader
npm init npm i webpack vue vue-loader
npm warns you that you need dependencies, follow the prompts to install
warn
Install the corresponding loader
npm i css-loader vue-template-compiler
2.2 Configure webpack to load app.vue File
First create the src folder, and create app.vue as the main code file under it, and index.js as the entry file.
Basic file
The content of the app.vue file is as follows:
<template> <p id="text">{{text}}</p> </template> <script> export default{ data(){ return { text: 'abc' } } } </script> <style> #test{ color: red; } </style>
In
Create the webpack.config.js file in the same directory as src, configure the entry, and output the output
Create the package.json file and webpack .config.js file
//webpack.config.js const path = require('path') module.exports = { entry: path.join(__dirname,'src/index.js'), //调用Index.js作为入口文件 output: { //打包完的js文件会在bundle.js中,这个文件待会会自动生成的 filename: 'bundle.js', path: path.join(__dirname,'dist') //用来存放bundle.js文件的地址,自己定义 }, module: { rules: [{ test: /.vue$/, loader: 'vue-loader' }] } }
index.js file as the entry
//index.js import Vue from 'vue' import App from './app.vue' const root = document.createElement('p') document.body.appendChild(root) new Vue({ render: (h) => h(App) }).$mount(root)
Configuration package.json file scripts command, add build
"scripts": { "test": "echo \"Error: no test specified\" && exit 1", "build": "webpack --config webpack.config.js" },
Enter the npm run build command in the console to package, as shown in the figure after successful packaging
After webpack packaging is completed
2.3 Configure webpack to load non-Js files
Webpack.config.js file specific configuration
Module in webpack.config.js: Add rules:[] in the {} module to set the file types that webpack needs to recognize. The vue file type has been set before, so you need to add css/images.
//webpack.config.js module: { rules: [ { test: /.vue$/, loader: 'vue-loader' }, { test: /.css$/, use:[ 'style-loader', 'css-loader' ] }, { test: /\.(gif|jpg|png|svg)$/, use: [{ loader: 'url-loader', options: { limit: 1024, name:'[name].[ext]' } }] } ] }
Execute the command in the console and install the corresponding loader
##
npm i style-loader css-loader url-loader file-loaderTest the packaging effect of non-js type filesGoal: Import the contents of these non-js type files in js codeCreate the test file test.css in the src subdirectory. And put jpg pictures in images instead (one is enough, emmm, I put too many so I won’t delete them yet)
Import these non-js files in Index.js.
//index.js import Vue from 'vue' import App from './app.vue' import './assets/styles/test.css' //import css文件 import './assets/images/0.jpg' //import 图片 const root = document.createElement('p') document.body.appendChild(root) new Vue({ render: (h) => h(App) }).$mount(root)Finally execute
npm run build on the console to test the results.
//webpack.config.js { test:/.styl$/, use: [ 'style-loader', 'css-loader', 'stylus-loader' ] }Then install the loader file required for stylus on the console
npm i style-loader stylus-loaderFinally execute
npm run build on the console to test the results.
npm i webpack-dev-serverThen, modify the package.json file and add dev configuration under build
因为在windows和mac环境下的命令会不同,这里安装cross-env 包,使得在不同开发环境下命令相同。
npm i cross-env
再次修改package.json文件,在“build:”和“dev:"行添加dev命令
cross-env NODE_ENV=development 后面不变
package.json文件build
然后,在webpack.config.js文件中进行判断。
首先,配置config.devServer
webpack2之后就可以直接用config.devServer进行配置了。
更改文件头部几行代码
在文件的最后加上如下代码
config.devServer
注意:
host:'0.0.0.0'不要直接写localhost,这样别人的电脑就访问不了了;port不要被占用,不然会打不开
最后.安装html-webpack-plugin插件使得html可以作为入口,自动包含JS
npm i html-webpack-plugin
修改webpack.config.js文件
config.js
config.js
至此,dev配置基本完成
控制台执行 npm run dev
npm run dev
打包成功的话就可以在浏览器中查看效果了,
如果出现错误,根据提示修改,注意端口是否占用。我的8000端口占用了,后来用了8080端口就好了
浏览器访问:localhost:8080,可以查看渲染效果。恩,背景图0.jpg是我爱豆23333。笔芯。注意左上角有红色的abc。
浏览器效果
2.6最后还有一些东西要加在config.js中
最后还要加一些东西
1) historyFallback:{}
因为我们做的是单页应用,所以要加一下地址映射到入口index.html,这个先忽略
2) 热加载功能。
hot功能,可以实现局部渲染:比如你改了一个组件的代码,页面只重新渲染这个组件而不是整个页面进行渲染,不需要进行刷新操作。
3) 一些插件
webpack.HotModuleReplacementPlugin()启动hot功能
webpack.NoEmitOnErrorsPlugin()去除一些不必要的信息
4) 浏览器调试代码功能的工具
在浏览器中调试的时候,代码不会转码。
config.devtool = “#cheap-module-evel-source-map”
最后配置完成后,重新npm run dev一次
npm run dev
成功之后,可以在浏览器中测试热加载效果,修改app.vue文件中的text的内容,就可以看到左上角那个红色的字在变了emmmm
//app.vue <template> <p id="text">{{text}}</p> </template> <script> export default{ data(){ return { text: 'abc' //打开浏览器,然后直接改这里就可以实时看到文字变化效果了。 } } } </script> <style> #test{ color: red; } </style>

web端指的是电脑端的网页版。在网页设计中我们称web为网页,它表现为三种形式,分别是超文本(hypertext)、超媒体(hypermedia)和超文本传输协议(HTTP)。

区别:1、前端指的是用户可见的界面,后端是指用户看不见的东西,考虑的是底层业务逻辑的实现,平台的稳定性与性能等。2、前端开发用到的技术包括html5、css3、js、jquery、Bootstrap、Node.js、Vue等;而后端开发用到的是java、php、Http协议等服务器技术。3、从应用范围来看,前端开发不仅被常人所知,且应用场景也要比后端广泛的太多太多。

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。

怎么解决高并发大流量问题?下面本篇文章就来给大家分享下高并发大流量web解决思路及方案,希望对大家有所帮助!

web有前端,也有后端。web前端也被称为“客户端”,是关于用户可以看到和体验的网站的视觉方面,即用户所看到的一切Web浏览器展示的内容,涉及用户可以看到,触摸和体验的一切。web后端也称为“服务器端”,是用户在浏览器中无法查看和交互的所有内容,web后端负责存储和组织数据,并确保web前端的所有内容都能正常工作。web后端与前端通信,发送和接收信息以显示为网页。
