安装webpack npm install webpack//安装webpack npm install --save-dev webpack//在项目中安装webpack npm init //创建package.json文件 配置 //package.json "scripts" : { "test" : "echo \"Error: no test specified\" && exit 1" , "dev" : "webpack-dev-server" , "build" : "webpack" } , 使用yarn: yarn init -y yarn add webpack webpack-cli -d//-d是开发环境配置打包后没有 npx webpack//打包后dist文件夹里形成app.js yarn add webpack-dev-server -d//安装运行工具 不使用yarn: npm i webpack-cli -g//全局安装 或者npm install webpack-cli --save-dev//正常安装 webpack hello.js -o hello.bundle.js//终端打包 运行 npm run dev (开发环境输出的demo.js没有压缩); npm run build (生产模式输出的demo.js压缩过);

How to run Webpack Dev Server --https --hot --inline

问题 Is there a way to leverage running the webpack-dev-server on https when configuring using CLI? The problem is the connection to socket.io is over http and not https . A workaround exists, but its very annoying. Manually include https webpack-dev-server in your index.html <script src="https://localhost:8080/webpack-dev-server.js"></script> Configure each end point to include webpack/hot/only-dev-server . app: [ 'webpack/hot/only-dev-server', './app.js' ], // ... more entry points that include

webpack和webpack-dev-server的区别 第一, webpack 是构建 webpack-dev-server 除了构建,还提供web服务 第二, webpack.config.js的路径参数区别 entry都一样。 ouput不太一样。 path和webpack一起,构建后输出文件的位置,这是真实的物理地址。 publicPath和webpack-dev-server一起,当执行webpack-dev-server的时候,第一步首先跟webpack一样,先构建输出,然后提供web访问,这是该输出文件是在内存中 默认情况下不设置publicPath则输出文件默认运行在和webpack-dev-server的同级目录的,一般也就是根目录。如果设置了publicPath那么html中的引用也要相对改变。 如下面: 我改了publicPath 相应html中的路径也要改变 http://webpack.github.io/docs/webpack-dev-server.html 第三, webpack-dev-server 运行之后 1、先构建,输出文件在内存中,引用构建后的输出文件根据publicPath(默认是根目录),2、 每次修改,自动刷新 来源: https://www.cnblogs.com/nuoyiamy/p/6074756.html

首先要安装node 一、webpack 1、新建一个文件夹amazing,然后进入文件夹 命令行运行 npm init - y ( y -- 》代表yes ,省去了默认选项点击 ) 然后命令行中一顿回车 完成后,生成一个package.json文件 2、安装webpack和webpack-cli npm install webpack webpack - cli -- save - dev 3、在文件中创建src、public两个文件夹和webpack.config.js配置文件 ①、在子文件夹public中新建index.html(此文件为入口文件模板,注意是模板) ②、在子文件夹src内新建main.js文件(此文件为项目入口主js文件) ③、webpack-config.js const path = require ( 'path' ) ; module . exports = { entry : { app : './src/main.js' //需要打包的文件 } , output : { filename : 'bundle.js' , //输入的文件名是什么,dist里面生成的文件名也是什么 path : path . resolve ( __dirname , 'dist' ) //指定生成的文件目录 } } ; 4、安装webpack-dev-server

webpack-dev-server, historyApiFallback not working (webpack-4, react-router-4)

眉间皱痕 提交于 2020-01-15 03:53:11
问题 I am testing out react-router4 with webpack4, but I can't get webpack-dev-server's setting: {historyApiFallback: true} to work.

Here is my webpack.config.js: const HtmlWebpackPlugin = require('html-webpack-plugin'); module.exports = () => { return { mode: 'development', devtool: 'source-map', devServer: { port: 8888, historyApiFallback: true, stats: 'minimal' }, resolve: { extensions: ['*', '.mjs', '.js', '.jsx'] },

unable to see request logs in webpack-dev-server

旧街凉风 提交于 2020-01-12 06:35:55
问题 I am using webpack-dev-server to act as a CDN server locally to serve various static assets like css, js, html etc. Everything runs fine but for debugging purposes, I am unable to see the requests received by the CDN server. webpack-dev-server just goes silent and doesn't show any info/errors once it has compiled the bundle of static assets. I went through the command line help too but with no success. 回答1: Basically, webpack-dev-server uses express to spawn a webserver. To enable seeing logs
