using async/await with webpack-simple configuration throwing error: RegeneratorRuntime not defined

In order to use await/async you will need to install a couple of Babel dependencies. This works with Vuejs project –

npm install --save-dev babel-polyfill
npm install --save-dev babel-plugin-transform-regenerator

Once installed, you will need to modify your .babelrc file to use the plugin as follows –

{
    "plugins": ["transform-regenerator"]
}

and also your webpack.config.js file to use the regenerator as follows –

require("babel-polyfill");

module.exports = {
  entry: ["babel-polyfill", "./app.js"]
};

Make the necessary changes according to your project structure and filename etc.
