Refitter 0.1.5-alpha

Refitter

Refitter is a CLI tool for generating a C# REST API Client using the Refit library.

Usage:

To generate code from an OpenAPI specifications file, run the following:

$ refitter [path to OpenAPI spec file]

This will generate a file called Output.cs which contains the Refit interface and contract classes generated using NSwag

Here's an example generated output from the Swagger Petstore example

using Refit;
using System.Threading.Tasks;
using System.Collections.Generic;

namespace GeneratedCode
{
    public interface ISwaggerPetstore
    {
        [Put("/pet")]
        Task<Pet> UpdatePet([Body]Pet body);

        [Post("/pet")]
        Task<Pet> AddPet([Body]Pet body);

        [Get("/pet/findByStatus")]
        Task<ICollection<Pet>> FindPetsByStatus();

        [Get("/pet/findByTags")]
        Task<ICollection<Pet>> FindPetsByTags();

        [Get("/pet/{petId}")]
        Task<Pet> GetPetById(long? petId);

        [Post("/pet/{petId}")]
        Task UpdatePetWithForm(long? petId);

        [Delete("/pet/{petId}")]
        Task DeletePet(long? petId);

        [Post("/pet/{petId}/uploadImage")]
        Task<ApiResponse> UploadFile(long? petId, [Body]FileParameter body);

        [Get("/store/inventory")]
        Task<IDictionary<string, int>> GetInventory();

        [Post("/store/order")]
        Task<Order> PlaceOrder([Body]Order body);

        [Get("/store/order/{orderId}")]
        Task<Order> GetOrderById(long? orderId);

        [Delete("/store/order/{orderId}")]
        Task DeleteOrder(long? orderId);

        [Post("/user")]
        Task CreateUser([Body]User body);

        [Post("/user/createWithList")]
        Task<User> CreateUsersWithListInput([Body]ICollection<User> body);

        [Get("/user/login")]
        Task<string> LoginUser();

        [Get("/user/logout")]
        Task LogoutUser();

        [Get("/user/{username}")]
        Task<User> GetUserByName(string username);

        [Put("/user/{username}")]
        Task UpdateUser(string username, [Body]User body);

        [Delete("/user/{username}")]
        Task DeleteUser(string username);
    }
}

Here's an example usage of the generated code above

using Refit;
using System;
using System.Threading.Tasks;

namespace GeneratedCode;

internal class Program
{
    private static async Task Main(string[] args)
    {
        var client = RestService.For<ISwaggerPetstore>("https://petstore3.swagger.io/api/v3");
        var pet = await client.GetPetById(2);

        Console.WriteLine($"Name: {pet.Name}");
        Console.WriteLine($"Category: {pet.Category.Name}");
        Console.WriteLine($"Status: {pet.Status}");
    }
}

The RestService class generates an implementation of ISwaggerPetstore that uses HttpClient to make its calls.

The code above when run will output something like this:

Name: Gatitotototo
Category: Chaucito
Status: Sold
