Node fetch is needed for example react-apollo

[SylarRuby]

On first implementation, I received the following

fetch is not found globally and no fetcher passed, to fix pass a fetch for your environment like https://www.npmjs.com/package/node-fetch.

Which gives an example:

import fetch from 'node-fetch';
import { createHttpLink } from 'apollo-link-http';

const link = createHttpLink({ uri: '/graphql', fetch: fetch });

Thought I'll share this.
