• In schema.graphqls define the result we’ll get back from the query by defining the following type:

  Code Block
  type local_todo_items_result { items: [local_todo_item!]! }

  Notice here we’ve used ! in two places. This indicates the field is non-nullable. We’ve used this here to say that we always expect an array, by putting the exclamation mark on the outside of the array [...]!. We also used it to to say that the elements of the array cannot be null [my_type!].

• Now we have the result defined, let’s define the query. We do this by extending the type Query and adding our query into it. Let’s do this:

  Code Block
  extend type Query { local_todo_items: local_todo_items_result! }

  This defines that the query local_todo_items should return the local_todo_items_result type we defined earlier.
