How do I get a stream inside a resolver so that I may read a file that has been upload by a client?

Hi everyone! I was working on a graphql schema, and I would like to have a logout mutation. Is there a way to clear the context for future mutations/queries? Any help is appreciated, thank you 🙏

Hey there! Does anyone have an example how I would use

wrap

? I’m specifically trying to harness it for Authentication purposes but I can’t seem to figure it out.

Hi, I am using custom data class(Address) in mutation input an got this error:

Introspection must provide output type for fields, but received: Address!.

Used data classes:

data class Address(
    val label: String? = null,
    val street: String? = null,
    val city: String? = null,
)
data class ChangeAddress(
    val userid:Id,
    val address: Address,
)

Mutation is defined like this:

mutation("changeAddress") {
    resolver { input: ChangeAddress, context: Context ->
        // change the addresss.....            
    }
}

What could be the problem?

After a long break. I'm back and I'm looking for more maintainers to help me maintain the project and grow the KGraphQL community. People are welcome to write to me privately here on slack and we can discuss more about becoming a maintainer. https://github.com/aPureBase/KGraphQL/discussions/187

Hi, I am trying to figure out if the following case is supported by KGraphQL. I need to write an api where the input is something like the composite design patter.. For keeping the API general I want the input type to be the type of the base class. When I try to do it I get a

Failed to coerce

exception. So the input type would be:

sealed class Base {
    data class Leaf(val prop: Int): Base()
    data class Composite(val prop: List<Base>): Base()
}

I tried different kind of kotlinx.serialization annotations to make it work but it seems like behind the scenes it failed since Jackson is used. Also when I try to use the base as an

inputType

I get an error that it doesn't have any fields. I also tried to use the derived classes as

inputType

. Without success. Last, in the examples I can only see something which returns a unionType (not something the accepts a unionType).

Hi, earlier today I found out that this bug causes characters in Japanese to be garbled in our application which uses KGraphQL. There is a workaround proposed on this thread. Would it make sense if I send a PR to apply the proposed workaround on this line for the benefit of other KGraphQL users?

What do you propose to do if I need to support multiple graphql endpoints (public api and internal api for example). Looks like we can't call install twice. I also want a different schema per endpoint.

have been thinking about that myself, not sure of which route to go. But am thinking about going with this solution: https://github.com/aPureBase/KGraphQL/issues/190

then you could just call

graphql

multiple times, to create multiple graphql endpoints, or multiple for require authentication and not authentication

Another option is to make it possible to configure multiple endpoints in the plugin

And a separate schema for each

could be, but the current design for the ktor plugin is a bit ugly when used with authentication

but for now, if you just create a PR for solving the issue, it will be included in the next release 🙂 But some bigger change is coming when upgrading to ktor 2.0 or moving to a route extension structure. And when moving to ktor, I will make sure that we will still have 1.x support also, probably in two different packages.

You mean if I will solve it on top of my proposal?

no, I mean I will just take your solution to that encoding issue, along with whatever solution we will move into in the future

@itzik kasovitch With some small tweaks you could install the plugin twice. I have that approach in production and it works: https://github.com/aPureBase/KGraphQL/pull/193 Don't know if this is something that could come to aPureBase-Upstream until the Design of #190 is implemented @jeggy.

Hey I see that there is an introspection schema here and specified through the code. Is there a way to generate the json from this for use in other tools and clients?

Hey, is there an estimate on when KGraphQL 0.18.1 will be released?

Hi people, I'm new in KGraphQL and I have the same problem that Tomas Kormanak solved... My problem is that I can't understand how he solved it.

Is it possible to wrap errors in 200 OK responses (

wrapErrors

in

GraphQL.Configuration

) but also log them into the console at the same time (behaviour with

wrapErrors

set to false)?

👋 I am wondering how to get a request header in my resolver. I am assuming there is a way to grab it with the Context. However I can't seem to find an example and have been unable to figure it out on my end.

Hi people, I'm having a problem that I don't know if it is about kgraphql, but I don't know where to start. I can't use version

0.18.1

of kgraphql, I have to downgrade to

0.18.0

to use it.

Hey guys, I created a thread sharing my notes while studying the internals of the library, in case it helps anyone else looking to contribute https://github.com/aPureBase/KGraphQL/discussions/213 Feedback is appreciated 🙂 and many thanks for this awesome project :kotlin-intensifies:

Hi @jeggy, I want to propose significant changes in the library that would make it possible to fully support generic types. I'm proposing we rely only on java.lang.reflect.Type for associating to TypeDefs, and for all of the compilation logic. Basically we replace all uses of *KClass<*>* and KType with java.lang.reflect.Type, to avoid kotlin reflection limitations (Top reflection-based serialization libraries also rely exclusively on java.lang.reflect.Type under the hood: Jackson, Gson, Moshi). I've created a POF branch and this comment to describe the proposal in detail. Please let me know if this kind of change is something you agree with, in order to support the use case.

how can i add extensions in graphql response. my response is like this

data class GraphQLResponse(
    val data: String? = null,
    val errors: List<Error>? = null,
    val extensions: Map<String, Any>? = null
)

Hello! Is graphql-multipart supported?

Potential silly question here.. Is there a way to determine what fields a user is requesting for their response? I am thinking I should be able to optimize some database queries if I know they only want specific fields in the response.
