Examples

NextJS

1. Define Apollo Client

lib/apollo.js

import { withApollo } from 'next-apollo';
import ApolloClient from 'apollo-client';
import { InMemoryCache, IntrospectionFragmentMatcher } from 'apollo-cache-inmemory';
import { createContentfulLink } from '@cmpsr/contentful-core/lib/client';

import introspectionQueryResultData from '../../schema/fragmentTypes.json';

const fragmentMatcher = new IntrospectionFragmentMatcher({
  introspectionQueryResultData,
});

const apolloClient = new ApolloClient({
  link: createContentfulLink({
    space: process.env.CONTENTFUL_SPACE_ID,
    accessToken: process.env.CONTENTFUL_ACCESS_TOKEN_DELIVERY,
  }),
  cache: new InMemoryCache({ fragmentMatcher }),
});

export default withApollo(apolloClient);

2. Wrap Next App (or Page(s))

pages/_app.js

import React from 'react'
import withApollo from '../lib/apollo'

const MyApp = ({ Component, pageProps }) => <Component {...pageProps} />;

export default withApollo({ ssr: true })(MyApp);

pages/index.js

import React from 'react'
import withApollo from '../lib/apollo'

const Home = props => {
  ...
};

export default withApollo({ ssr: true })(Home);

React App
