  // If you prefer graphiql over graphql playground
  router.get(

  router.get("*", async ctx => {

  });

  server.use(router.routes());

  server.listen(port, () => {
    console.log(`> Ready on http://localhost:${port}`);
    console.log(`> GraphiQL IDE available on http://localhost:${port}/graphiql`);
    console.log(`> GraphQL Server (And GraphQL Playground) ready at http://localhost:${port}${graphQLServer.graphqlPath}`);
  });

I love this! Thanks for the starting code
