Possible spread error on IE 11 (Webpack, VueJS)?

I'm getting this error on IE 11:

enter image description here enter image description here

Here are my webpack and babel configuations:

webpack configuration

const path = require('path');
const webpack = require('webpack');
const { VueLoaderPlugin } = require('vue-loader');
const StylishWebpackPlugin = require('webpack-stylish');
const ForkTsCheckerWebpackPlugin = require('fork-ts-checker-webpack-plugin');

const withLogRocket = process.argv.includes('--with-logrocket');
if (withLogRocket) {
  /* eslint-disable no-console */
  console.info('-> Building with LogRocket enabled.');
  /* eslint-enable */
}

// Base webpack configuration for all environments.
module.exports = {
  context: path.dirname(__dirname),
  entry: {
    app: './src/main.js',
  },
  target: 'web',

  output: {
    filename: '[name].[contenthash].js',
    hashDigestLength: 8,
  },

  resolve: {
    extensions: ['.ts', '.js', '.vue'],
    alias: {
      '@': path.resolve(__dirname, '../src'),
    },
  },

  module: {
    rules: [
      {
        test: /\.js/,
        exclude: /node_modules/,
        use: {
          loader: 'babel-loader',
        },
      },
      {
        test: /\.ts$/,
        exclude: /node_modules/,
        use: [
          {
            loader: 'babel-loader',
          },
          {
            loader: 'ts-loader',
            options: {
              transpileOnly: true,
            },
          },
        ],
      },
      {
        test: /\.vue$/,
        loader: 'vue-loader',
      },
      {
        test: /\.css$/,
        use: [
          'style-loader',
          'css-loader',
        ],
      },
      {
        test: /\.scss$/,
        use: [
          'style-loader',
          'css-loader',
          'sass-loader',
        ],
      },
    ],
  },

  stats: 'errors-only',

  plugins: [
    new VueLoaderPlugin(),
    new ForkTsCheckerWebpackPlugin({
      tslint: true,
      reportFiles: ['src/**/*.ts'],
    }),
    new StylishWebpackPlugin(),
    new webpack.DefinePlugin({
      USE_LOGROCKET: withLogRocket,
    }),
  ],
};

babelrc file

{
    "presets": ["env"],
    "plugins": [
        "transform-es2015-destructuring",
        "transform-object-rest-spread"
    ]
}

I'm not really sure if this is due to the ...sources spread or among others. I'm pretty sure I have the babel-transform-object-rest-spread package but I still don't get why I have this error, I also used babel-preset-env. As you can see on the configuration I am running a pure JS (VueJS, typescript) app. I've read numerous posts about using polyfill and among others but it didn't help me make our app run on IE11.

You're using env preset but never defining what environment Babel is supposed to generate code for (so I assume IE 11 is not supported in that case).

Without any configuration options, babel-preset-env behaves exactly the same as babel-preset-latest (or babel-preset-es2015, babel-preset-es2016, and babel-preset-es2017 together).

So just add the options object having the targets property set to something the like of

"browsers": [ "last 1 version", "ie >= 11" ]

like this:

{
    "presets": ["env", {
      "targets": {
        "browsers": [ "last 1 version", "ie >= 11" ]
      }
    }],
    "plugins": [
        "transform-es2015-destructuring",
        "transform-object-rest-spread"
    ]
}

I also highly recommend you switch to Babel 7 asap.
