Custom Fetch

This examples shows how to leverage the extension system to override the "exchange" hook's default fetch implementation.

import { Graffle } from 'graffle'

const graffle = Graffle
  .create()
  .transport({ url: `http://localhost:3000/graphql` })
  .anyware(({ exchange }) =>
    exchange({
      using: {
        fetch: async () => {
          return new Response(JSON.stringify({ data: { pokemon: [{ name: `Pokemon Mocked!` }] } }))
        },
      },
    })
  )

const data = await graffle.gql`{ pokemon { name } }`.send()

console.log(data)

Outputs

{
  "pokemon": [
    {
      "name": "Pokemon Mocked!"
    }
  ]
}
