In GraphQL, can you change the structure of the output in an alias?

问题

Let's say I've got a GraphQL query that looks like this:

query {
  Todo {
    label
    is_completed
    id
  }
}

But the client that consumes the data from this query needs a data structure that's a bit different- e.g. a TypeScript interface like:

interface Todo {
  title: string  // "title" is just a different name for "label"
  data: {
    is_completed: boolean
    id: number
  }
}

It's easy enough to just use an alias to return label as title. But is there any way to make it return both is_completed and id under an alias called data?

There is no way to do that. Either change the schema to reflect the client's needs or transform the response after it is fetched on the client side.
