'import' and 'export' may only appear at the top level

Question

I'm using webpack with vuejs. Webpack does its thing, but when I look at the outputted app.js file, it gives me this error.

'import' and 'export' may only appear at the top level

I'm assuming it's a problem with babel not converting the code? Because I'm getting this in the browser when viewing the application.

Unexpected token import

Here's my entry.js for my vuejs application:

/*jshint esversion: 6 */
import Vue from 'vue';
import App from './App.vue';
import VueRouter from 'vue-router';
Vue.use(VueRouter);
require('./css/style.scss');

// Export the vue router
export var router = new VueRouter({
  hashbang: false,
  root: '/'
  // history: true
});

// Set up routing and match routes to components
router.map({
  '/': {
    component: require('./components/home/Home.vue')
  }
});

// Redirect to the home route if any routes are unmatched
router.redirect({
  '*': '/'
});

// Start the app on the #app div
router.start(App, '#app');

Here's my webpack.config.js:

var ExtractTextPlugin = require('extract-text-webpack-plugin');
var path = require('path');

module.exports = {
  entry: './src/entry.js',
  output: {
      filename: './public/js/app.js'
  },
  devtool: 'source-map',
  plugins: [
    new ExtractTextPlugin('./public/css/style.css')
  ],
  module: {
    preLoaders: [{
        test: /\.js$/, 
        exclude: /node_modules/,
        loader: 'jshint-loader'
    }],
    loaders: [{
        test: /\.scss$/,
        loader: ExtractTextPlugin.extract(
            'style',
            'css!sass'
        ),
    },
    {
        test: /\.vue$/,
        loader: 'vue'
    },
    {
        test: /\.js$/,
        exclude: /node_modules/,
        include: [
          path.resolve(__dirname, "src/services"),
        ],
        loader: 'babel-loader',
        query: {
          presets: ['es2015']
        }
    }]
  }
};

I got this error when I was missing a closing bracket.

Simplified recreation:

const foo = () => {
  return (
    'bar'
  );
}; <== this bracket was missing

export default foo;
