This Course in a Nutshell

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.

This course comes with a running Github repository with the the finished code, as well as starting points for different sections of the course in case that you want to code along, which we recommend as its the best way to learn.

This course answers the common question: how far can we go in Angular while using only plain RxJs and nothing more, without introducing any state management library?

It turns out that the simple set of techniques taught in this course are very well suited for a wide range of applications, especially in-house built enterprise applications

In this course, you will learn exactly how to use RxJs to design and develop both the service and the view layers of your application, and you will understand both the advantages and the pitfalls of the reactive approach

Particularly when it comes to state management, it turns out that we can already go very far by leveraging only plain Angular and RxJs techniques, without using an additional state management library like for example NgRx

These simplified state management techniques are adequate and sufficient for a large range of applications, and we believe that you should consider them first before thinking of adopting a full-blown state management solution

How far can you go with these techniques? That's what you will find out in this course.

Course Overview

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 aproach 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.
