Graphql Subscription "graphql-ws" Support

[ranatallal09]

I have a quick question guys does this client supports subscription with latest "graphql-ws" protocol?

[rose-a]

yes it does, since v6.0.0

using GraphQL;
using GraphQL.Client.Http;
using GraphQL.Client.Serializer.Newtonsoft;

var graphQLClient = new GraphQLHttpClient ("ws://localhost:3000/graphql", new NewtonsoftJsonSerializer());

var userJoinedRequest = new GraphQLRequest {
    Query = @"
                subscription {
                    gameUpdates {
                        id
                        name
                    }
                }"
};

IObservable<GraphQLResponse<dynamic>> subscriptionStream
    = graphQLClient.CreateSubscriptionStream<dynamic>(userJoinedRequest);

var subscription = subscriptionStream.Subscribe(response => Console.WriteLine($"user '{response.Data }' joined"));

subscription.Dispose();



// See https://aka.ms/new-console-template for more information
Console.WriteLine("Hello, World!");

I am trying to connect the subscription but it just prints the hello world after some time and no log gets printed at server side regarding connection established.

@rose-a anything on this?

You're disposing the subscription immediately after creating it... put a blocking operation like Console.ReadLine() before subscription.Dispose() to actually allow the program to live and receive subscription values...

I also recommend to define your return object properly instead of using dynamic.

var subscriptionStream = graphQLClient.CreateSubscriptionStream(
    userJoinedRequest, 
    () => new { 
        gameUpdates = new { 
            id = string.Empty, 
            name = string.Empty 
        }
    });
var subscription = subscriptionStream.Subscribe(response => Console.WriteLine($"user '{response.Data.gameUpdates.name}' joined"));

Console.Write("Press enter to terminate...");
Console.ReadLine();
