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
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

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
