Indexing List Type field in a GraphQL type from within a Query

Say I have the following GraphQL Schema



query {
allAuthors: [Author]
}

type Author {
id: ID!
name: String!
books: [Book]
}

type Book {
id: ID!
name: String!
author: Author!
}


Now I can successfully run the following query to get all the authors and their associated books



query {
allAuthors {
name,
books {
name
}
}
}


However, if I only want to get the first three books for all authors, how would I go about doing something like that? Can we index the books field in the Author type from within a query? If so, how?



I tried something like this and it doesn't work



query {
allAuthors {
name,
books[3] {
name
}
}
}

          GraphQL doesn't have syntax for this.



          You can add a "limit" parameter to a field, and this is common enough:



          type Query {
          allAuthors(limit: Int, offset: Int): [Author!]!
          }
          type Author {
          id: ID!
          name: String!
          books(limit: Int, offset: Int): [Book!]!
          }


          If you add parameters like this to the schema, then the query you want (for all authors, get the first three books) could look like



          {
          allAuthors {
          name
          books(limit: 3) {
          name
          }
          }
          }
