Mastering ServiceStack Mastering ServiceStack covers real-life problems that occur over the lifetime of a distributed system and how to solve them by deeply understanding the tools of ServiceStack. Distributed systems is the enterprise solution that provide flexibility, reliability, scaling, and performance. ServiceStack is an outstanding tool belt to create such a system in a frictionless manner, especially sophisticated designed and fun to use. The book starts with an introduction covering the essentials, but assumes you are just refreshing, are a very fast learner, or are an expert in building web services. Then, the book explains ServiceStack's data transfer object patterns and teach you how it differs from other methods of building web services with different protocols, such as SOAP and SOA.
Whilst adding this is not strictly necessary, it does go a long way to helping keep the code clean. If we fail to tell the UserStore which DbContext to use, it falls back to some default value. This code will help prevent you from tearing your hair out later wondering why you are getting the super-helpful error message shown above.
API Controller We need to expose some data to our client when we write it. The Seed method will pre-populate some books and reviews automatically for us.
Instead of dropping the code in directly for this class it is very long , please refer to the Configuration. This code gives us a little bit of starting data to play with, instead of having to add a bunch of data manually each time we make changes to our schema that require the database to be re-initialized not really in our case as we have an extremely simple data model, but in larger applications this is very useful.
NET framework; the introduction of async and await. Writing asynchronous code in this manner allows the thread to be released whilst data Books and Reviews is being retrieved from the database and converted to objects to be consumed by our code. When the asynchronous operation is complete, the code picks up where it was up to and continues executing. For this we will need a ReviewsController with the relevant Post and Delete methods.
Remove review ; await context. The first method, Post allows the user to add a new review. The second parameter is a view model that wraps around the Review entity itself.
So why bother? Also, it helps prevent unwanted information being sent to the client. With this approach we have to explicitly expose data to the client by adding properties to the view model. For this scenario, this approach is probably a bit overkill, but I highly recommend it keeping your application secure is important, as well as is the need to prevent leaking of potentially sensitive information.
I highly recommend checking out. Important note: In order to keep our API RESTful, we return the newly created entity or its view model representation back to the client for consumption, removing the need to re-fetch the entire data set. The Delete method is trivial. We accept the Id of the review we want to delete as a parameter, then fetch the entity and finally remove it from the collection. Calling SaveChangesAsync will make the change permanent. Meaningful response codes We want to return useful information back to the client as much as possible.
Notice that the Post method returns NotFound , which translates to a HTTP status code, if the corresponding Book for the given review cannot be found.
This is useful for client-side error handling. We will open up an OAuth endpoint to client credentials and return a token which describes the users claims.
For each of the users roles we will add a claim which could be used to control which views the user has access to on the client-side. Add a new class to the project called Startup. You could use a static helper class here, but the preferred method from the MSDN documentation seems to be leaning towards using partial classes specifically. Configuration; using BooksAPI.

The custom attribute here is QueryableResult, which uses the AutoQueryable library to handle paging, filtering, and sorting on the server side. Before ASP. NET Core, they were very similar. Both followed an MVC type pattern with controllers and actions. NET Core. You can include the NuGet package for Microsoft. The code is on GitHub if you are curious as to what it does. This will wire up the HttpResponseMessageOutputFormatter so that it knows how to properly serialize that response.
NET Core with the compatibility shim. Using the New ASP. From any controller, you can return a View or object and MVC will take care of serializing it for you.
