Overview of this book

The HTML over WebSockets approach simplifies single-page application (SPA) development and lets you bypass learning a JavaScript rendering framework such as React, Vue, or Angular, moving the logic to Python. This web application development book provides you with all the Django tools you need to simplify your developments with real-time results. You’ll learn state-of-the-art WebSocket techniques to realize real-time applications with minimal reliance on JavaScript. This book will also show you how to create a project with Docker from the ground up, test it, and deploy it on a server. You’ll learn how to create a project, add Docker, and discover development libraries, Django channels, and bidirectional communication, and from then, on you’ll create real projects of all kinds using HTML over WebSockets as a chat app or a blog with real-time comments. In addition, you’ll modernize your development techniques by moving from using an SSR model to creating web pages using WebSockets over HTML. With Django, you’ll be able to create SPAs with professional real-time projects where the logic is in Python. By the end of this Django book, you’ll be able to build real-time applications, as well as gaining a solid understanding of WebSockets with Django.

In this chapter, we created a functional chat with private rooms and groups, like other software such as Slack or Teams, with very few lines of JavaScript (no comments, less than 35 lines). In addition, we have taken the first steps in an authentication system. We can now register and manage clients in different Channels, depending on our needs, and know who is connected or disconnected. The magic is over – we are now masters of Channels.

In the next chapter, Chapter 6, Creating SPAs on the Backends, we will deal with the last few elements that are necessary to dynamize a site, such as changing pages, deciding when we want to update a whole section or add a new HTML fragment, working with sessions so as not to depend so much on the database, and validating the origin of the data to avoid cross-site request forgery (CSRF) with WebSockets. With all the skills we will have acquired, we will develop a complete SPA by building a blog in Chapter 7, Creating a Real-Time...
