Asp Web Api Breeze in layered application

Question

I currently have an ASP Web API project and the goal is to create a SPA.

I'm using EF Code first and have the following solution structure:

- BookClub.Entities
- BookClub.DataAccess (DbContext, generic Repository, ...)
- BookClub.BusinessLogic (UOW, Facade pattern)
- BookClub.Web (ASP Web Api (v2))

I would like to give Breeze a try but I don't really know what would fit where. All the examples use a Context or Repository in the ApiController. This should be avoided and per entity a BusinessLogic layer Facade should be used. But how would my Controller look like then?

Has anyone ever done this before?

Answer 1

Your controller just facilitates the conversion of your business logic entities for the views you define. If you have build up a business layer then simply use it in the controllers get/put methods. The code below would return a Book in json format.

[HttpGet]
[ValidateAntiForgeryToken]
[OutputCache(NoStore = true, Duration = 0)]
public ActionResult GetBook(int bookID)
{
    BookBL bookBL=new BookBL();
    Book model=bookBL.SelectOne(bookID);
    return Json(model, JsonRequestBehavior.AllowGet);
}

//Return a partial view instead 
[HttpGet]
[ValidateAntiForgeryToken]
[OutputCache(NoStore = true, Duration = 0)]
public ActionResult GetBookView(int bookID)
{
    BookBL bookBL=new BookBL();
    Book model=bookBL.SelectOne(bookID);
    return PartialView("Partials/BookView", model);
}
