Add a graphQL fragment to the schema and have it accessible to all queries

Question

The following is done correctly in the schedule

fragment BookGridFields on Book { _id title } { allBooks { ...BookGridFields } } 

---

My question is, can I specify a fragment directly in my scheme, right below where my type of book is defined, for example

 type Book { _id: String title: String pages: Int weight: Float authors: [Author] } fragment BookGridFields on Book { _id title } 

So I can just run queries like this

 { allBooks { ...BookGridFields } } 

without having to define a fragment as part of my request.

Currently the above errors with

Unknown fragment \ "BookGridFields \"
