Standard Graphql

This example shows how to configure output to approximate the traditional GraphQL ExecutionResult type.

import { Graffle, Preset } from 'graffle'

const graffle = Graffle
  .create({ output: Preset.traditionalGraphqlOutput })
  .transport({ url: `http://localhost:3000/graphql` })
  .anyware(async ({ exchange }) => {
    return exchange({ input: { ...exchange.input, request: { ...exchange.input.request, url: `bad` } } })
  })

const result = await graffle.gql(`{ query { thisWillError } }`).send()

console.log(result)
