Apollo Notes

Resolver

fieldName: (parent, args, context, info) => data;

Lazy query in graphql

Sometimes we are not interested in getting all values of a node, we can do some tricks to prevent loading extra contents or generating infinite circular structure. Below example the users have many books, and each book have one owner, which is a user again. How can we query the user without returning the books, or reuse the node resolver if we want to return the books?
