Polyfills and browser compatibility (Affecting SEO)

See original GitHub issue


I had issues getting listed on Google, because it doesn’t render anything on Google’s Fetch and Render feature.

I so I dig into the issue and it was Array.find() couldn’t find on Google’s browser env. Since Google’s Fetch and Render didn’t provide console.log output I had to debug this for more than 4 hours doing a lot of trial and error stuff.


This is happening because we don’t use babel-polyfill or any other polyfill or shims.

What we can do?

I can understand the reason behind not using polyfills. But we should document clearly on why we do it and how to add some polyfills.

I simply added following line to src/index.js and everything works fine.

import from 'airbnb-js-shims';
