How to limit the number of items of nested array?

[Damar225]

Hello, I Have a query like this

`
query {
  doctors @rest(type: "doctors", path: "/doctors/") {
	  Result {
		  Id
		  FirstName
		  LastName
                  Items (limit: 10) {
                      id
                      title
                  }
            }
}
`

I want to get only 10 items from the Items, but I get the full list!

Is This doable or not?

Thank you.

Short answer: no.

Your REST API always returns the full list, so the @rest annotation can’t magically change that. If it could, you’d still have a problem, because the backend would return the full list, let's say 10000 items, and then @rest would filter away 9990 items on the client side. Then you'd need some way to access the remaining items. @rest() is meant as a small escape hatch for a few APIs, or as a stepping stone while converting the Backend to GraphQL. It can't fix having the wrong backend API. Does that make sense?

Obviously, you can always filter the results before displaying them — if this is just a “the UI doesn’t need more that 10 items here” sort of situation.

Apollo-link-rest just can’t invent the “limit” feature (there’s infinite other hypothetical features we could add there).
