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.

What is functional programming?

Functional programming is a programming paradigm that has gained a lot of popularity since 2010. In the last few years, many functional frameworks or libraries have appeared in many programming languages, and functional languages have seen a rise in interest. Functional programming is not a new programming paradigm, but getting into it from a theoretical perspective can be intimidating.

The world of functional programming is full of new terms (such as monoid, monad, currying, purity, and higher-order function) that can seem difficult to comprehend, and some of them come with different definitions depending on the source of the information. But functional programming has some very interesting benefits:

  • Functional code is deterministic, with behavior that can (at least in theory) be proven
  • Functional code can isolate side effects from the...
