Why use arrays to represent singular values? Also, singular names for potentially plural results is bad form, however you want to sugar coat it. This might be cool for an API provider, but it looks like a nightmare to deal on the API consumer side of things. I like the basic GraphQL results better (still not sold on GraphQL as a whole, but alas). This offloads needless complexity onto the consumer.
Thanks for the feedback here. I modified the post a bit to not show the arrays because the library doesn't return arrays but rather aync generators. The power of this is that you have a single interface for interacting with all data no matter if there are zero or many results.
This is library is a proof of concept. In a perfect world, there would be a nice wrapper around this query result for interacting with the data.
queryResult.get('order').first()
With all of this said, it doesn't have to be this way. I'm exploring ideas here. The important concept is that GraphQL can be used to express the expectations of the client and a library like Graphable JSON can go find the needed data in the API. This gives the expressiveness of GraphQL with the benefits of REST. The sky is the limit. Thanks again for the feedback!
