ReferenceError: regeneratorRuntime is not defined

... which I\'ve managed to reproduce in a very minima

Answer 1

Also you could do the following with es2015 preset and transform-regenerator plugin:

.babelrc

{
  "presets": ["es2015"],
  'plugins': [
    'transform-regenerator'
  ]
}

Code

let regeneratorRuntime =  require("regenerator-runtime");
// You code with ES6 generators

P.S. Of course you should install babel-plugin-transform-regenerator npm package.
