For building the service layer in Angular 2 we have many options available. Should we build a service layer in a similar way to Angular 1, or are there better ways ? How do we use the new HTTP module ? Everything around this module revolves around the notion of Observable. What is an Observable?

The goal of this course is to answer these questions by introducing the fundamentals of RxJs and Functional Reactive Programming and see how these notions apply in practice to the Angular 2 HTTP module. We will learn how to use the HTTP module and Observables to build service layers in Angular 2.

Covering RxJs completely would be the subject or a very large course, but the good news is that if we we are planning to use RxJs mostly to do HTTP calls, then we can focus on only a small subset of operators.

The course structure is simple: we will introduce RxJs and Observables and give a couple of simple examples, and aply it directly by using it to build the service layer of an Angular 2 Application. We will then see how to do the most common HTTP operations that you will do the most often in practice. RxJs does not have to be hard, we can approach it gradually and a great way to jumpstart our understanding of it is to use it in a very concrete case: in the case of this course we will focus on the Angular 2 HTTP Module.
