What's the best term for a top-level field on the Query type?

Question

type Query {
  foo: String
}

What is foo ? The spec doesn't give an official term. Some options include "query", "method", "endpoint" or "resource" from REST, and "action".

Answer 1

I call it a "query root field" and I likewise call Query the "query root type".

I don't recommend calling it a method, endpoint, resource, or action, because those are those conflate it with concepts from REST that are actually pretty different. Your whole GraphQL endpoint is the resource, effectively.
