  +
  +const client = createClient({
  + url: 'https://myHost/graphql',
  + exchanges: defaultExchanges,
  +});
  +
  +const App = () => (
  + <Provider value={client}>
  + <Dogs />
  + </Provider>
  +);
  +
  +const Dogs = () => {
  + const [result] = useQuery({
  + query: `{ dogs { id name } }`,
  + });
  +
  + if (result.fetching) return <p>Loading...</p>;
  + if (result.error) return <p>Oh no...</p>;
  +
  + return result.data.dogs.map(dog => <p>{dog.name} is a good boy!</p>);
  +};
