Getting Started

One of the most straightforward and common use-cases of GraphQL-Utils is checking if a query contains a certain path. We can do this using the hasFields() utility:

import { hasFields } from "@jenyus-org/graphql-utils";

const resolvers = {
  Query: {
    posts(_, __, ___, info) {
      const requestedAuthor = hasFields(info, "posts.author");
      console.log(requestedAuthor);
    },
  },
};

This will output true for the following query:

{
  posts {
    id
    title
    body
    author {
      id
      username
      firstName
      lastName
    }
  }
}
