import { HttpLink } from 'apollo-link-http';
import { InMemoryCache } from 'apollo-cache-inmemory';

import App from './App';

const GITHUB_BASE_URL = 'https://api.github.com/graphql';

const httpLink = new HttpLink({
  uri: GITHUB_BASE_URL,
  headers: {
    authorization: `Bearer undefined`
  }
});

const cache = new InMemoryCache();

const client = new ApolloClient({
  link: httpLink,
  cache
});

HttpLink... Set a GraphQL endpoint

ReactDOM.render(
  <ApolloProvider client={client}>
    <App />
  </ApolloProvider>,
  document.getElementById('root')
);

Apollo Provider... Wrap the whole app component
