Simple Aggregation

For the sake of the following examples, let's consider a scenario where a table called Posts exists, having expected fields and relations like title, body, author, etc.

Using aggregators in queries

You can fetch aggregations on nodes using an aggregation query. Currently the available aggregation function is count.

Request

query {
  author(name: "Huxley") {
    name
    posts {
      count
      items {
        title
      }
    }
  }
}

Response

{
  "data": {
    "author": {
      "name": "Huxley",
      "posts": {
        "count": 2,
        "items": [
          { "title": "10 things you never knew about Possums" },
          { "title": "3 things you never wanted to know about Possums" }
        ]
      }
    }
  }
}
