• Allow fetch-compatible options in constructor #9

Example:

import { GraphQLClient } from 'graphql-request'

const client = new GraphQLClient('my-endpoint', {
 credentials: 'include',
 mode: 'cors'
})

const query = `{
  Movie(title: "Inception") {
    releaseDate
    actors {
      name
    }
  }
}`

client.request(query).then(data => console.log(data))
