Hands-On Reactive Programming with Python

By: Romain Picard

Overview of this book

Reactive programming is central to many concurrent systems, but it’s famous for its steep learning curve, which makes most developers feel like they're hitting a wall. With this book, you will get to grips with reactive programming by steadily exploring various concepts This hands-on guide gets you started with Reactive Programming (RP) in Python. You will learn abouta the principles and benefits of using RP, which can be leveraged to build powerful concurrent applications. As you progress through the chapters, you will be introduced to the paradigm of Functional and Reactive Programming (FaRP), observables and observers, and concurrency and parallelism. The book will then take you through the implementation of an audio transcoding server and introduce you to a library that helps in the writing of FaRP code. You will understand how to use third-party services and dynamically reconfigure an application. By the end of the book, you will also have learned how to deploy and scale your applications with Docker and Traefik and explore the significant potential behind the reactive streams concept, and you'll have got to grips with a comprehensive set of best practices.

An Introduction to Reactive Programming

This first chapter covers the principles of reactive programming and ReactiveX. It is composed of three parts. The first part explains what reactive programming is and how it compares to other concepts and paradigms that are often used in event-driven programming. The second part explains the foundations of ReactiveX and RxPY, its Python implementation. This exploration of RxPY is explained with a simple example that allows us to understand the basics of ReactiveX. Finally, the last part is dedicated to the documentation of the ReactiveX project and the documentation of your projects. By the end of this chapter, you will be able to write some ReactiveX code and understand existing code.

The following topics will be covered in this chapter:

  • What is reactive programming?
  • An introduction to ReactiveX and RxPY
  • A reactive echo application
  • Marble diagrams
  • Flow diagrams
