мой .babelrc

{
    "presets": [
        "@babel/preset-env"
    ],
    "plugins": [
        "@babel/plugin-proposal-class-properties"
    ]
}

мой webpack.config.js

let path = require('path');

let conf = {
    entry: './es6/scripts.js',
    output:{
            path: path.resolve(__dirname,'./js'),
            filename: 'main.js',
            publicPath: 'js/'
    },
    devServer: {
        overlay:true
    },
    module: {
        rules:[
            {
                test:'/\.js$/',
                loader: 'babel-loader',
                //exlude 'node_modules'    
            }
        ]
    }
};

module.exports = conf;

мой package.json

{
  "name": "frontend",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "dev": "webpack-dev-server --mode development --open",
