Sciensoft.Hateoas 3.2.0

A library to help you achieve HATEOAS using a fluent language and lambda expression for configuring your ASP.NET Core RESTful/Web APIs. Based on the REST application architecture style, Uniform Interface, constraint Hypermedia As The Engine Of Application State (HATEOAS).

The good thing is, there is no need to inheritance or additional code in your models or addition of extra result filters to support its functionality. They all come beautifully out of the box with Sciensoft.Hateoas

Sciensoft.Hateoas threats lambda as first-class citizen, so your configuration starts with a lambda expression. This library DO NOT enforce REST constraints (https://rebrand.ly/restful-explained) or Richardson Maturity Level (https://rebrand.ly/richardson-maturity-model), and this has to be done by you, Sciensoft.Hateoas helps you only with the implementation of HATEOAS in your resource.

Get Started

Sciensoft.Hateoas gets installed using Nuget package manager.

Install-Package Sciensoft.Hateoas

Or dotnet CLI dotnet add package Sciensoft.Hateoas.

Configuration

Using a fluent language, allows you to easily configure by adding the service to .NET Core dependency injection pipeline.

public void ConfigureServices(IServiceCollection services)
{
  services
    .AddMvc()
    .AddLinks(policy =>
    {
      policy
        .AddPolicy<BookViewModel>(model =>
        {
          model
            .AddSelf(m => m.Id, "This is a GET self link.")
            .AddRoute(m => m.Id, BookController.UpdateBookById)
            .AddRoute(m => m.Id, BookController.DeleteBookById)
            .AddCustomPath(m => m.Id, "Edit", method: HttpMethods.Post, message: "Edits resource")
            .AddCustomPath(m => $"/change/resource/state/?id={m.Id}", "ChangeResourceState", method: HttpMethods.Post, message: "Any operation in your resource.")
            .AddExternalUri(m => m.Id, "https://my-domain.com/api/books/", "Custom Domain External Link")
            .AddExternalUri(m => $"/search?q={m.Title}", "https://google.com", "Google Search External Links", message: "This will do a search on Google engine.");
        });
    });
}

Here is how your controller looks like, no additional injection or attribute decoration is required. Please check our Sample Project out!

[Route("api/books")]
public class BookController : ControllerBase
{
    public const string UpdateBookById = nameof(UpdateBookById);
    public const string DeleteBookById = nameof(DeleteBookById);

    [HttpGet]
    public ActionResult<IEnumerable<BookViewModel>> Get()
    { /* Code omitted for simplicity */ }

    [HttpGet("{id:guid}")]
    public ActionResult<BookViewModel> Get(Guid id)
    { /* Code omitted for simplicity */ }

    [HttpPost]
    public IActionResult Post([FromBody] BookViewModel book)
    { /* Code omitted for simplicity */ }

    [HttpPut("{id:guid}", Name = UpdateBookById)]
    public IActionResult Put(Guid id, [FromBody] BookViewModel book)
    { /* Code omitted for simplicity */ }

    [HttpDelete("{id:guid}", Name = DeleteBookById)]
    public IActionResult Delte(Guid id)
    { /* Code omitted for simplicity */ }
