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.

Chapter 1

Is event-driven programming only possible with some programming languages?

Event-driven programming and reactive programming can be used with virtually any programming language and any programming paradigm. However, not all programming languages are equal in their ability to write event-driven code. Usually, the more low-level the programming language, the most difficult it is to write event-driven code in it. The term low-level is used here to describe the functionalities supported by the programming languages, not the fact that it is designed for system programming rather than applicative programming. A language with no support for closures, anonymous functions, and generators will lead to event-driven code that's hard to write, read, and maintain.

What are the differences between reactive programming and reactive systems?

Reactive programming is a way to structure...
