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.

Reactive Streams for Remote Communication

This is the last chapter in which we'll increase your knowledge of ReactiveX. This chapter explains how observables can be extended outside a single application. The first part of this chapter explains what existing communication patterns there are and how they relate to observables. The second part details how multiplexing is designed and why all of its steps are necessary. The last part is an implementation of the publish/subscribe protocol.

The following topics will be covered in this chapter:

  • Communication patterns and observables
  • Observable multiplexing
  • Implementing publish/subscribe
