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

This chapter covered all the base concepts of asynchronous programming and how they work in Python. You should now understand what it means to yield or await a coroutine and know the differences between blocking and non-blocking designs. Hopefully, the short history of asynchronous programming in Python and the examples of asynchronous programming with callback also helped you understand why Python is one of the few languages with best-in-class support of asynchronous programming.

Moreover, you should also be familiar enough with the AsyncIO APIs to write your own asynchronous applications. This chapter only covered the basic usage of AsyncIO, but the features presented here are the most-used ones. Other more advanced features will be introduced in this book, as they are needed in other examples.

One last word on this chapter: Do not be fooled by the simplicity of the...
