Batch query executor which provides following features:

  • Allows specifying multiple operationNames when executing a GraphQL query document. All operations would be executed in order inferred from the dependencies between queries.
  • Support for @export(as: "foo") directive. This directive allows you to save the results of the query execution and then use it as a variable in a different query within the same document. This provides a way to define data dependencies between queries.
  • When used with @export directive, the variables would be automatically inferred by the execution engine, so you don't need to declare them explicitly (though you can)
