Using babel-polyfill with webpack

Question

I keep on encountering the following error when trying to use the babel-polyfill with webpack. How should i use it without the loader like babel-loader? It was mentioned that it will emulate the es2015 environment.

ERROR in ./components/App.component.jsx
Module parse failed: /home/krishna/AndroidStudioProjects/jancan/web/components/App.component.jsx Unexpected token (6:1)
You may need an appropriate loader to handle this file type.

 @ multi main

Edit

my webpack config

module.exports = {
    entry: ['babel-polyfill', './components/App.component.jsx'],
    output: {
        path: 'dist/',
        filename: "bundle.js"
    },
    loaders: [
    {
      test: /\.jsx?$/,
      exclude: /(node_modules|bower_components)/,
      loader: 'babel', // 'babel-loader' is also a valid name to reference
      query: {
        presets: ['es2015','react']
      }
    }
  ]
};

I have added babel-loader and still i am getting same error

The error is pretty descriptibe, you have syntax error in your `App.component.jsx` file. Go and check it — Jakub Jankowski, Oct 11 '16 at 07:11

This is how I use babel-polyfill in my Webpack config.

  entry: {
    app: ['babel-polyfill', 'main']
  }
