Fixing Regenerator Runtime Error Integrating Redux Saga

While integrating redux-saga an annoying little error may pop up in the console.

Uncaught ReferenceError: regeneratorRuntime is not defined

It took a bit of research to figure out why, and it shouldn't have since the notice is listed in the README for redux-saga. Most browsers do not support ES2015 generators, so require using a polyfill.

I am going to assume usage of the react-slingshot bootstrap as mentioned in a previous post about usable bootstrap with react-slingshot.

Add the import for babel-polyfill prior to importing redux-saga to the src/store/configureStore.js.

import 'babel-polyfill';
import createSagaMiddleware from 'redux-saga';

Enjoy.
