Reactive Angular Course (with RxJs). Build Angular Applications in Reactive style with plain RxJs – Patterns, Anti-Patterns, Lightweight State Management

This course is a catalog of commonly used design patterns (and some anti-patterns) that every Angular developer should know. The goal of the course is to teach you how to comfortably design and develop applications in Angular in Reactive style using just plain RxJs, and nothing more.

We are going to start our course by taking a small Angular application that is written in imperative style, and we are going to talk about some of the problems of that approach. Then, we are going to refactor the application and explain step-by-step how to implement it in reactive style instead.

We will explain in detail every RxJs operator that we come across in this course, the first time that we need each operator.

We are going to start with a fully stateless solution first, but later we are going to improve the user experience by applying some simple RxJs-only state management techniques. We are going to use these patterns in order to handle some of the data of the application, as well as the user authentication profile.

The key element needed to implement lightweight state management is RxJs behavior subjects so we will cover those in detail in the course. We will also provide step-by-step reactive style solutions for common UI functionality like loading indicators or error messages.
