Implementing a live directive

[eljenso]

I'm trying to implement a live directive, which keeps the caller of the query up-to-date.
This is my current code, which does just resolve() with the directive.

const typeDefs = /* GraphQL */ `
  directive @live on FIELD | FIELD_DEFINITION

  type Todo {
    text: String!
    completed: Boolean!
  }

  type Query {
    allTodos: [Todo]! @live
  }
`;

const resolvers = {
  Query: {
    allTodos() {
      return someTodoArray;
    }
  }
};

const executableSchema = makeExecutableSchema({
  typeDefs,
  resolvers
});

addDirectiveResolveFunctionsToSchema(executableSchema, {
  live(resolve) {
    return resolve();
  }
});

How would I push new results to the caller with this approach?
Is there a way to get a reference to the caller to push new results?
