Babel 6 regeneratorRuntime is not defined

Question

I\'m trying to use async, await from scratch on Babel 6, but I\'m getting regeneratorRuntime is not defined.

.babelrc file

{
    \"presets\": [ \"es2

Alternatively, if you don't need all the modules babel-polyfill provides, you can just specify babel-regenerator-runtime in your webpack config:

module.exports = {
  entry: ['babel-regenerator-runtime', './test.js'],

  // ...
};

When using webpack-dev-server with HMR, doing this reduced the number of files it has to compile on every build by quite a lot. This module is installed as part of babel-polyfill so if you already have that you're fine, otherwise you can install it separately with npm i -D babel-regenerator-runtime.
