How to use distinct in GraphQL query?

Question

Here is query where I try to use distinct in graphQl query:

query{
    contacts(take: 10, distinct: true) {
        firstName
        lastName
        title
         


        

Answer 1

GraphQL has no built-in sorting/filtering. It is up to the server to implement features like that, so if you're relying on a third party API and it doesn't support it then you will have to filter the response yourself.

Answer 2

Here is a example of distinct query.

query {
  contacts {
    distinct(field: title)
  }
}

Result will be.

{
  "data": {
    "contacts": {
      "distinct": [
        "This is my test post",
        "This is my test post1",
        "This is my test post2"
      ]
    }
  }
}

This query binds all titles and deduplicates.
