        }
      }

import { App, Request } from 'https://deno.land/x/tinyhttp/mod.ts'
import { GraphQLHTTP, GraphQLSchema, GraphQLObjectType, GraphQLString } from 'https://deno.land/x/gql/mod.ts'

const schema = new GraphQLSchema({
  query: new GraphQLObjectType({
    name: 'Query',
    fields: {

app
  .post('/graphql', GraphQLHTTP({ schema, context: (request: Request) => ({ request }) }))
  .listen(3000, () => console.log(`☁  Started on http://localhost:3000`))

$ curl -X POST localhost:3000/graphql -d '{ "query": "{ hello }" }'
