Abstractions for the Websocket transport used in GraphQL.Client
$ dotnet add package GraphQL.Client.Abstractions.WebsocketA GraphQL Client for .NET Standard over HTTP.
Provides the following packages:
| Package | Downloads | Nuget Latest |
|---|---|---|
| GraphQL.Client |  |  |
| GraphQL.Client.Abstractions |  |  |
| GraphQL.Client.Abstractions.Websocket |  |  |
| GraphQL.Client.LocalExecution |  |  |
| GraphQL.Client.Serializer.Newtonsoft |  |  |
| GraphQL.Client.Serializer.SystemTextJson |  |  |
| GraphQL.Primitives |  |  |
The Library will try to follow the following standards and documents:
// To use NewtonsoftJsonSerializer, add a reference to NuGet package GraphQL.Client.Serializer.Newtonsoft
var graphQLClient = new GraphQLHttpClient("https://api.example.com/graphql", new NewtonsoftJsonSerializer());var heroRequest = new GraphQLRequest {
Query = @"
{
hero {
name
}
}"
};var personAndFilmsRequest = new GraphQLRequest {
Query =@"
query PersonAndFilms($id: ID) {
person(id: $id) {
name
filmConnection {
films {
title
}
}
}
}",
OperationName = "PersonAndFilms",
Variables = new {
id = "cGVvcGxlOjE="
}
};Be careful when using byte[] in your variables object, as most JSON serializers will treat that as binary data! If you really need to send a list of bytes with a byte[] as a source, then convert it to a List<byte> first, which will tell the serializer to output a list of numbers instead of a base64-encoded string.
public class ResponseType
{
public PersonType Person { get; set; }
}
public class PersonType
{
public string Name { get; set; }
public FilmConnectionType FilmConnection { get; set; }
}
public class FilmConnectionType {
public List<FilmContentType> Films { get; set; }
}
public class FilmContentType {
public string Title { get; set; }
}
var graphQLResponse = await graphQLClient.SendQueryAsync<ResponseType>(personAndFilmsRequest);
var personName = graphQLResponse.Data.Person.Name;Using the extension method for anonymously typed responses (namespace GraphQL.Client.Abstractions) you could achieve the same result with the following code:
var graphQLResponse = await graphQLClient.SendQueryAsync(personAndFilmsRequest, () => new { person = new PersonType()} );
var personName = graphQLResponse.Data.person.Name;public class UserJoinedSubscriptionResult {
public ChatUser UserJoined { get; set; }
public class ChatUser {
public string DisplayName { get; set; }
public string Id { get; set; }
}
}var userJoinedRequest = new GraphQLRequest {
Query = @"
subscription {
userJoined{
displayName
id
}
}"
};
IObservable<GraphQLResponse<UserJoinedSubscriptionResult>> subscriptionStream
= client.CreateSubscriptionStream<UserJoinedSubscriptionResult>(userJoinedRequest);
var subscription = subscriptionStream.Subscribe(response =>
{
Console.WriteLine($"user '{response.Data.UserJoined.DisplayName}' joined")
});subscription.Dispose();Blazor WebAssembly differs from other platforms as it does not support all features of other .NET runtime implementations. For instance, the following WebSocket options properties are not supported and will not be set:
