GraphQL Query

The Benzene instance is not only used to create transport handlers but also to execute GraphQL queries just like the graphql-js library.

const GQL = new Benzene({ schema });

const { data, errors } = await GQL.graphql({
  source: `
    query pokemon($id: ID!) {
      pokemon(id: $id) {
        name
        image
        abilities
      }
    }
  `,
  contextValue: { trainer: "Ash Ketchum", region: "Kanto" },
  variables: { id: 25 },
});

The API is the same as using the graphql export from graphql-js, with the only difference that there is no schema since it is already defined upon creating the Benzene instance.

formatErrorFn from the Benzene instance will apply here so the returned errors field includes formatted errors.
