Ability to cascade the GraphQL field resolvers in Springboot app

[dkveera16]

I am trying to build an aggregator function using GraphQL as the front , which invokes REST and GraphQL services.
I am able to get the list of request fields from DataFetchingEnvironment variable.
I am unable to cascade the list of fields and use it for the next call that I make to another GraphQl Service.
Is there way for this to be done?

If I understand your problem statement correctly, you could try setting the following config in your build configuration:
generateDataFetchingEnvironmentArgumentInApis=true

Hi, Thanks for the reply. It helped me get the arguments in the request . I then need to cascade thus to another GraphQL call that I make further down the line in the application. Is there a way for it to be done ? Thanks, Veera

Hi @kobylynskyi ,
Not sure if you had a chance to look at this?
My current Springboot app gets a list of fields that it needs to respond with, but when it calls another Graphql app, it is not able to inform what are the fields.

@dkveera16 can you please clarify a little bit more (perhaps with some examples) about what are you trying to achieve. Thanks.

Hi,
We have an aggregator APP (AGG) that collects information from various sources( B , C).
All three apps have graphql .
Lets take a simple schema
type BlogPost {
title: String
content: String
}

All three apps have the same schema. So if I call AGG app and say I need only title, I should be able to pass this to B and C and retrieve only title from B and C.
Currently I can see that AGG has full awareness that it needs only title. But there is no way to cascade that when we build B or C queries.
This means that we are always getting back title and content from b and c.
I am hoping there is a constructor that I can use when building queries in b an c where I can pass arguments that I received from datafetchers.

Hope this clarifies the question
