Can graphql return aggregate counts?

Question

Graphql is great and I\'ve started using it in my app. I have a page that displays summary information and I need graphql to return aggregate counts? Can this be done?

Answer 1

This depends on whether you build the aggregator into your schema and are able to resolve the field.

Can you share what kind of GraphQL Server you're running? As different languages have different implementations, as well as different services (like Hasura, 8base, and Prisma).

Also, when you say "counts", I'm imagining a count of objects in a relation. Such as:

query {
  user(id: "1") {
    name
    summaries {
      count
    }
  }
}

// returns
{
  "data": {
    "user": {
      "name": "Steve",
      "summaries": {
        "count": 10
      }
    }
  }
}

8base provides the count aggregate by default on relational queries.
