Inheritance for Angular Services
Most Microsoft developers understand the significance of inheritance, when writing their server-side code, but don’t really understand how to make this object oriented principal useful in the client-side code. The principal is the same on the client-side, and it gives you the same benefits. The Angular.Net Starter App has an Angular service which all other services are derived from. This is a TypeScript file called “baseServices.ts”. This class contains the logic for making the restful calls to the server. It contains a “Get”, “Put”, “Post” and “Delete” method. It also contains the logic to log any errors, and maintains caching objects in the local storage for the “Analytics”.
You do understand why you want to be able to reuse this kind of logic throughout your application’s services? And have it only in one place? You do. Don’t you?
