Integration with apollo graphiqlExpress?

[FredericLatour]

I guess that's not easy to integrate with Express and graphiqlExpress

// The GraphQL endpoint
app.use('/graphql', bodyParser.json(), graphqlExpress({schema}));

// GraphiQL, a visual editor for queries
app.use('/graphiql', graphiqlExpress({ endpointURL: '/graphql',  }));

Any idea?
