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 */ }
}
