graphiql-route.jsx

export default
  <Route path="/graphiql" component={() =>
    <GraphiQL fetcher={(graphQLParams) =>
      fetch(window.location.origin + '/graphql', {
        method: 'post',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify(graphQLParams),
        credentials: 'same-origin',
      }).then(response => response.json())
    } />
  } />
