basic webpack config

webpack.config.js

const path = require('path')
const distFolder = path.resolve(__dirname, 'dist')
const srcFolder = path.resolve(__dirname, 'src')

module.exports = {
    entry: ['./src/app.js'],
    output: {
        filename: 'app.min.js',
        path: distFolder
    },
    devServer: {
        contentBase: distFolder,
        compress: true,
        port: 4040
    },
    module: {
        loaders: [
            {
                test: /\.jsx?$/,
                loader: "babel-loader",
                include: path.join(__dirname, "src"),
                query: {
                    presets: ["env", "react"],
                    plugins: [
                        "transform-object-rest-spread"
                    ]
                }
            }
        ]
    }
};
