Populate an object and pass it in a request parameter in GraphQL

Question

How can we populate an object and pass it in a request parameter in GraphQL. For example, i want to get rid of sequence of parameters here in the GraphQL request and want to create an object and pass it as a single parameter.

{
 allBooks(first:20, orderBy:"myRating"){
  isn
  title
  authors
  publisher
 }
}

Answer 1

You can use GraphQL Input Types.

In your schema definition you need to define the input into something like:

input BooksInput {
  first: Int
  orderBy: String
}

And require it as the args type in your query, then use it as:

{
 allBooks($input: {first:20, orderBy:"myRating"}){
  isn
  title
  authors
  publisher
 }
}
