In the previous article, we have learned about the GraphQL integration with the ASP.NET Core application. We have created our first GraphQL query and fetched some data from the server side application. But we won’t stop on just basic queries. In this article, we are going to learn how to write advanced GraphQL queries and while doing that, we are going to show you how to handle errors and how to cache data inside a query. Furthermore, we are going to learn how to enhance our query (from a client side) with the named queries, aliases, arguments, and fragments....

The Strategy design pattern is a behavioral design pattern which allows us to define different functionalities, put each functionality in a separate class and make their objects interchangeable. In other words, we have a main Context object that holds a reference towards a Strategy object and delegates it by executing its functionality. If we want to change the way the Context performs its work, we can just replace the current Strategy object with another one.

Posted by | Apr 1, 2019 | ,

The Command pattern is a behavioral design pattern that we can use to turn a request into an object which contains all the information about the request.

Furthermore, this possibility to keep track of our operations gives us the opportunity to undo them as well.
