Trikot.graphql

Multiplaform graphql query implementation.

• Use Kotlinx.serialization to deserialize objects
• No codegen for now

Sending a graphql request

1 - Create the models for your response

import kotlinx.serialization.Serializable

@Serializable
data class DataResponse<T>(val data: T)

@Serializable
data class FooResponse(val foo: Foo)

@Serializable
data class Foo(val __typename: String, val id: String)

2 - Create a graphql query

class FooQuery(fooId: String) :
    AbstractGraphqlQuery<DataResponse<FooResponse>>(DataResponse.serializer(FooResponse.serializer())) {

    override val variables: Map<String, Any>? =
        mutableMapOf<String, Any>("fooId" to fooId)

    override val query = """
    query(${'$'}fooId: String!) {
        foo(fooId: ${'$'}fooId) {
            id
            __typename
        }
    }
    """
}

3 - Execute your query

val query = GraphqlQueryPublisher(FooQuery("3"))
query.execute()
query.subscribe(cancellableManager) {
    print(it.data.foo.id) // 3
}

Using with Trikot.datasources

val myDataSource = GraphqlDataSource<DataResponse<FooResponse>>(GraphqlPublisherFactoryImpl())
val dataSourceState = myDataSource.read(GraphqlQueryDataSourceRequest(FooQuery("3"), "cachableId-3"))
