Easy.Endpoints

Aspnetcore endpoints without the controller.
Docs
Sample Project

Setup

Add Easy.Endpoint services

    services.AddRequestEndpoints();

Add Easy.Endpoint to the application builder

app.UseEndpoints(endpoints =>  
  {  
    endpoints.AddEasyEndpoints();  
  });

And it will grab all implementations of IEndpoint. IEndpoint is expected to implement a single public method named Handle or HandleAsync Can extract paramters from route, body, query parameters and from HttpContext

Sample

Simple endpoint that will be grouped in swagger under Greetings

[EndpointController("Greetings")]  
public class HelloWorldEndpoint : IEndpoint  
{  
    public string Handle()  => "Hello World";
}

GET: /Book Returns a list of books in json format

public class GetBookEndpointHandler : IEndpoint
{
    public Task<Book[]> HandleAsync() => Task.FromResult(Array.Empty<Book>());
}

POST: /Book Accepts a Book in the body as Json and returns a Command Result

public class PostBookEndpointHandler : IEndpoint
{
    public PostBookEndpointHandler()
    {            
    }

    public Task<CommandResult> HandleAsync(Book body)
    {
        return Task.FromResult(new CommandResult { Successful = true, Message = "Yay!" });
    }
}

POST: /TestOne Alternatively can declare route and Method

[Post("TestOne")]
public class PostTestResponseEndpoint : IEndpoint
{
    public Task HandleAsync(TestResponsePayload body)
    {
        return Task.CompletedTask;
    }
}

Generic handler

Can declare generic handlers that can build routes for types
POST: /Animal/Cow
POST: /Animal/Dog

[EndpointController("Animal")]
[KnownTypes("Cow", typeof(Cow))]
[KnownTypes("Dog", typeof(Dog))]
[Post("[controller]/[type]")]
public class AnimalEndpointHandler<TAnimal> : IEndpoint where TAnimal : IAnimal
{
    public Task<string> HandleAsync(TAnimal body, CancellationToken cancellationToken)
    {
        return Task.FromResult(body.Says());
    }
}

EndpointResults

Handlers can return IEndpointResult for when more control over the end result is required.

[ProducesResponseType(200,Type = typeof(People))]  
[ProducesResponseType(404, Type = typeof(void))]  
[Get("People/{id:int}")]  
public class GetPeopleByIdEndpointHandler : IEndpoint  
{   
    private readonly IPeopleService peopleService

    public GetPeopleByIdEndpointHandler(IPeopleService peopleService)
    {
        this.peopleService = peopleService
    }

    public Task<IEndpointResult> HandleAsync(int id, CancellationToken cancellationToken)  
    {  
        var person = peopleService.AllPeople().SingleOrDefault(p => p.Id == id);  
        if (person is null)  
            return Task.FromResult<IEndpointResult>(new NoContentResult(404));  
        return Task.FromResult<IEndpointResult>(new JsonContentResult<People>(person));  
    }  
}
