Please add the ability to abort request, if it is in progress. See https://developers.google.com/web/updates/2017/09/abortable-fetch

I am using graphql-client to fetch data from GitHub.

Usually, errors returned from GitHub looks like this:

[{"message":"Could not resolve to an Organization with the login of 'GCI-AOSSIE'.","type":"NOT_FOUND","path":["organization"],"locations":[{"line":2,"column":3}]}]

However, sometimes GitHub returns errors as follows:

[{"message":"Something went wrong while executing your query. This may be the result of a timeout, or it could be a GitHub bug. Please include `E689:1AF6:67E816:BAAF4C:5BD321E1` when reporting this issue."}]

Note that it doesn't have locations field.
Under the latter circumstance,

I understand by convention errors should be an array. But let's take this example when shopify for invalid access-token returns response as

{
    "errors": "[API] Invalid API key or access token (unrecognized login or wrong password)"
}

can we to a type check and handle this problem?

For an example. I have an array of things that I want to save with one request.
Without graphql-client it would look something like this.

const query = `
  mutation {
    ${things.map((x, i) => `
        m${i}: createThing(data: {name: "${x.name}"}) { id }
      `).join(' ')}
   }`

How would you do it with graphql-client making use of variables?
