Linq2GraphQL generates C# classes from the GraphQL schema and and togheter with the nuget package Linq2GraphQL.Client it makes it possible to query the server using Linq expressions.
A simple query that will get the first 10 orders with the primitive properties of orders and the connected customer
var orders = await sampleClient
.Query
.Orders(first: 10)
.Include(e => e.Orders.Select(e => e.Customer))
.Select(e => e.Orders)
.ExecuteAsync();An example mutation where we add a new customer and return the Customer Id.
var customerId = await sampleClient
.Mutation
.AddCustomer(new CustomerInput
{
CustomerId = Guid.NewGuid(),
CustomerName = "New Customer",
Status = CustomerStatus.Active
})
.Select(e=> e.CustomerId)
.ExecuteAsync();Strawberry Shake removes the complexity of state management and lets you interact with local and remote data through GraphQL.
You can use Strawberry Shake to:
client.GetHero
.Watch(ExecutionStrategy.CacheFirst)
.Subscribe(result =>
{
Console.WriteLine(result.Data.Name);
})The ZeroQL is a high-performance C#-friendly GraphQL client. It supports Linq-like syntax, and doesn’t require Reflection.Emit or expressions. As a result, at runtime provides performance very close to a raw HTTP call.
You can use ZeroQL to:
var userId = 10;
var response = await qlClient.Query(q => q
.User(userId, o => new
{
o.Id,
o.FirstName,
o.LastName
}));// expose an existing data model with ASP.NET & EF Core
public class Startup {
public void ConfigureServices(IServiceCollection services)
{
services.AddDbContext<DemoContext>();
// Auto build a schema from DemoContext. Alternatively you can build one from scratch
services.AddGraphQLSchema<DemoContext>(options =>
{
// modify the schema (add/remove fields or types), add other services
});
}
public void Configure(IApplicationBuilder app, DemoContext db)
{
app.UseRouting();
app.UseEndpoints(endpoints =>
{
// defaults to /graphql endpoint
endpoints.MapGraphQL<DemoContext>();
});
}
}using System;
using System.Threading.Tasks;
using GraphQL;
using GraphQL.Types;
using GraphQL.SystemTextJson; // First add PackageReference to GraphQL.SystemTextJson
public class Program
{
public static async Task Main(string[] args)
{
var schema = Schema.For(@"
type Query {
hello: String
}
");
var json = await schema.ExecuteAsync(_ =>
{
_.Query = "{ hello }";
_.Root = new { Hello = "Hello World!" };
});
Console.WriteLine(json);
}
