Strongly typed client for GraphQL in .NET

This project is currently work in progress and contains only very basic functionality. Usage in production is discouraged unless you know what you're doing.

A typesafe way how to request data from GraphQL API.

First, you generate a model

You can get this Visual Studio extension which automatically generates a cs file out of graphql schema file.

For example this IDL

type Query {
	a: Int
	b(x: Int!): Int!
}

will be translated into

namespace Schema
{
    using System;
    using System.Collections.Generic;
    using Telia.GraphQL.Client.Attributes;

    public class Query
    {
        [GraphQLField("a")]
        public Int32? A
        {
            get;
            set;
        }

        [GraphQLField("b")]
        public Int32 B(Int32 x)
        {
            throw new InvalidOperationException();
        }
    }
}

Create a client based on your schema

This part will be eventually automated with schema generation

public class MyClient : GraphQLCLient<Query>
{
    public Client(string endpoint) : base(endpoint)
    {
    }
}

Then request your data using the generated model

Create requests towards your GraphQL API while keeping full intellisense over the schema.

For example:

var client = new MyClient("<your_endpoint>");

var data = client.Query(e => new
{
    a = e.A,
    b = e.B(12)
});

Console.Write(data.a);
Console.Write(data.b);
