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.

Summary

Here we are; with approximately 80 ReactiveX operators covered, you should now have all the keys to implement a reactive application by creating, combining, filtering, or implementing any logic.

Being at ease with all these operators is one of the difficult parts of ReactiveX. The framework contains many operators, sometimes with confusing names, and sometimes with similar names but different behaviors. Moreover, the 80 operators covered here are only half of all the available operators in RxPY! However, most of the remaining ones are variants of the ones described here.

This chapter can be used as a quick reference to find the operator adapted to each use case. Hopefully, for each operator, the example provided with the description should also help you to clearly understand how and when to use the operator.

Some operators can be difficult to comprehend. They are usually...
