hotchoc - graphql - getting started

 

Create a dotnet core api project using cli. I am using dotnet 8.

dotnet new webapi -n app 

Then add the hotchoc packages 

dotnet add package HotChocolate.AspNetCore

Then you can add the necessary code to Program.cs 

using HotChocolate;

using HotChocolate.AspNetCore;

var builder = WebApplication.CreateBuilder(args);

builder.AddGraphQLServer()

    .AddQueryType<Query>();

var app = builder.Build();

app.MapGet("/", () => "Hello World!");

app.Run();

AddQueryType<Query> - this query is a class that contain simple code here.

namespace app.model

{

    public class Query

    {

        public Book GetBook() =>

        new Book

        {

            Title = "C# in depth.",

            Author = new Author

            {

                Name = "Jon Skeet"

            }

        };

    }

    public class Book

    {

        public string Title { get; set; }

        public Author Author { get; set; }

    }

    public class Author

    {

        public string Name { get; set; }

    }

}

Next you need to add 

app.MapGraphQL();

That's it. Run your project. In your browser, go to /graphql endpoint.

Simple sample code can be found here.
