How can I do multiple mutations with one request using an array?

[cotterjd]

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?
