详解搭建es6+devServer简单开发环境

(编辑：jimmy 日期: 2024/11/20 浏览：2)

搭建基于es6和热加载的前端简单开发环境，适合demo类小项目，这样就不用依赖browsersync等多余的东西

目录结构

  1. /src
    1. index.js
    2. index.html
  2. /dist

安装依赖

注意版本，尤其是babel，可去babel的npm地址查看，那里不会错

#bebal相关
yarn add babel-core babel-loader babel-preset-env

# webpack相关
yarn add webpack webpack-cli webpack-dev-server html-webpack-plugin

package.json

{
 "name": "design-pattern",
 "version": "1.0.0",
 "description": "js设计模式的学习深入",
 "main": "index.js",
 "author": "axin <laputacloud@163.com>",
 "license": "MIT",
 "scripts": {
  "dev": "webpack-dev-server --config ./webpack.dev.config.js --mode development"
 },
 "dependencies": {},
 "devDependencies": {
  "babel-core": "^6.26.3",
  "babel-loader": "7",
  "babel-preset-env": "^1.7.0",
  "html-webpack-plugin": "^3.2.0",
  "webpack": "^4.19.1",
  "webpack-cli": "^3.1.0",
  "webpack-dev-server": "^3.1.8"
 }
}

webpack.dev.config.js

const path = require('path')
const htmlWebpackPlugin = require('html-webpack-plugin')

module.exports = {
 entry: './src/index.js',
 output: {
  path: __dirname,
  filename: './dist/bundle.js'
 },

 module: {
  rules: [{
   test: /\.js"htmlcode">



{
 "presets": ["env"]
}






然后就可以执行npm run dev就可以开启开发环境
