这篇文章主要介绍了怎么搭建es6+devServer开发环境,具有一定借鉴价值,感兴趣的朋友可以参考下,希望大家阅读完这篇文章之后大有收获,下面让小编带着大家一起了解一下。
目录结构
/src
index.js
index.html
/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?$/, exclude: /(node_modules)/, loader: 'babel-loader' }] }, plugins: [ new htmlWebpackPlugin({ template: './index.html' }) ], devServer: { contentBase: path.join(__dirname, './dist'), open: true, // 自动打开浏览器 port: 6688, // devServer对应的端口号 } }
.babelrc 可根据需要配置
{ "presets": ["env"] }
然后就可以执行npm run dev就可以开启开发环境
