We will begin by adding a very simple GraphQL server to a blank ASP.NET Core app. Modify Startup.cs to look like shown below.
./Startup.cs
using HotChocolate;
using HotChocolate.AspNetCore;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
namespace SlackClone
{
public class Query
{
public string Hello => "World";
}
public class Startup
{
// This method gets called by the runtime.
// Use this method to add services to the container.
// For more information on how to configure your application,
// visit https://go.microsoft.com/fwlink/?LinkID=398940
public void ConfigureServices(IServiceCollection services)
{
// Adds GraphQL Schema
services.AddGraphQL(services =>
SchemaBuilder.New()
.AddServices(services)
.AddQueryType<Query>()
.Create());
}
// This method gets called by the runtime.
// Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
// Adds GraphQL Service
app.UseGraphQL();
}
}
}
After Startup.cs has been modified, we can start the server by typing dotnet run . Once the server is running, open a command prompt/ terminal and type the following curl command. Verify if you are running a secure server or not you may need to update the url.
