Chapter 1: The Power of the Reactive Paradigm
This book is based entirely on useful reactive patterns in Angular applications. Reactive patterns are reusable solutions to a commonly occurring problem using reactive programming. Behind all of these patterns, there is a new way of thinking, new architecture, new coding styles, and new tools.
I know you are impatient to write your first reactive pattern in Angular, but before doing that, and to help you take full advantage of all the RxJS patterns and leverage the reactive paradigm, we will start by explaining, in detail, all the fundamentals. Additionally, we will prepare the groundwork for the following chapters. First, let's start with a basic understanding of the reactive paradigm, its advantages, and the problems it solves. And best of all, let's get into the reactive mindset and start thinking reactively.
We will begin by highlighting the pillars and the advantages of the reactive paradigm. Then, we will describe the relationship between Angular and RxJS. Finally, we will explain the Marble diagram and why it is useful.
Giving an insight into the fundamentals of the reactive paradigm is incredibly important. This will ensure you get the basics right, help you understand the usefulness of the reactive approach, and consequently, help you determine which situation it is best to use it in.
In this chapter, we're going to cover the following topics:
- Exploring the pillars of reactive programming
- Using RxJS in Angular and its advantages
- Learning about the marble diagram – our secret weapon
