Method Get

This example shows usage of the getReads method mode for the HTTP transport. This mode causes read-kind operations (query, subscription) to be sent over HTTP GET method. Note write-kind operations (mutation) are still sent over HTTP POST method.

import { Graffle } from './graffle/__.js'

const graffle = Graffle
  .create()
  .transport({
    methodMode: `getReads`, 
    headers: { tenant: `nano` },
  })
  .anyware(async ({ exchange }) => {
    console.log(exchange.input.request)
    return await exchange()
  })

// The following request will use an HTTP POST method because it is
// using a "mutation" type of operation.
await graffle.gql`mutation { addPokemon(attack:0, defense:0, hp:1, name:"Nano", type: grass) { name } }`.send()

// The following request will use an HTTP GET method because it
// is using a "query" type of operation.
await graffle.gql`query { pokemonByName(name: "Nano") { hp } }`.send()
