Preface

HTML over WebSockets simplifies the creation of single-page applications (SPAs) by avoiding frontend rendering, giving real-time responses, and simplifying the logic by moving it to the backend. In this book, you won't learn how to use a JavaScript rendering framework such as React, Vue, or Angular, instead moving the logic to Python. This will simplify your developments, giving you real-time results with all the tools provided by Django.

Developers will learn state-of-the-art WebSockets techniques to realize real-time applications with minimal reliance on JavaScript. They will also learn, from the ground up, how to create a project with Docker, test it, and deploy it on a server.

You will follow the roadmap of a Django developer who wants to create SPAs with a good experience. You will create a project and add Docker, development libraries, Django channels, and bidirectional communication, and then you will create real projects of all kinds using HTML over WebSockets, such as a chat app or a blog with real-time comments. You will modernize your development techniques by moving from using an SSR model to creating web pages using HTML over WebSockets. With Django, you will create SPAs with professional real-time projects where the logic will be in Python.

By the end of the book, you will be able to make real-time applications and will have mastered WebSockets with Django.
