Execution

GraphQL generates a response from a request via execution.

A request for execution consists of a few pieces of information:

• The schema to use, typically solely provided by the GraphQL service.
• A Document containing GraphQL Operations and Fragments to execute.
• Optionally: The name of the Operation in the Document to execute.
• Optionally: Values for any Variables defined by the Operation.
• An initial value corresponding to the root type being executed. Conceptually, an initial value represents the “universe” of data available via a GraphQL Service. It is common for a GraphQL Service to always use the same initial value for every request.

Given this information, the result ofExecuteRequest()produces the response, to be formatted according to the Response section below.
