搭建基于es6和熱加載的前端簡(jiǎn)單開發(fā)環(huán)境，適合demo類小項(xiàng)目，這樣就不用依賴browsersync等多余的東西

目錄結(jié)構(gòu)

/src
index.js index.html
/dist

安裝依賴

注意版本，尤其是babel，可去babel的npm地址查看，那里不會(huì)錯(cuò)

#bebal相關(guān)yarn add babel-core babel-loader babel-preset-env# webpack相關(guān)yarn add webpack webpack-cli webpack-dev-server html-webpack-plugin

package.json

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, // 自動(dòng)打開瀏覽器  port: 6688, // devServer對(duì)應(yīng)的端口號(hào) }}

.babelrc 可根據(jù)需要配置

{ "presets": ["env"]}

然后就可以執(zhí)行npm run dev就可以開啟開發(fā)環(huán)境
