  2. Install Babel and The Presets:

    npm install --save-dev babel-core babel-preset-es2015

  4. Install babel-loader :

    npm install --save-dev babel-loader

  6. Configure Babel to use these presets by adding.babelrc

     { "presets": [ "es2015" ] }

  8. modify  webpack.config.js  to process all  . js  files using   babel-loader . 

      module.exports = {entry: './src/app.js ', Output: {path: './bin ', filename: ' App.bund             Le.js ',}, module: {loaders: [{test:/\.js$/, exclude:/node_modules/, Loader: ' Babel-loader ',}]}}

    We are excluding  Node_modules here because otherwise all external libraries would also go through Babel, slowing down compilation.

  10. Install the libraries want to use (in this example, JQuery):

    npm install --save jquery babel-polyfill

    We are using --save the instead --save-dev of this time, as these libraries'll be the used in runtime. We also use So, babel-polyfill ES2015 APIs is available in older browsers.

  12. Edit src/app.js :

     import ‘babel-polyfill‘; import cats from ‘./cats‘; import $ from ‘jquery‘; $(‘

  14. Bundle the modules using Webpack:

     webpack

  16. Add so this index.html app can be run:

    <!DOCTYPE html><body> <script src="bin/app.bundle.js"></script>
    17.
