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.

Summary

In this chapter, we have added some very interesting new capabilities to our project: switching between pages, creating server-side rendering versions of each path, creating a dynamic page, modifying URLs, updating specific sections, working with sessions, and avoiding CSRF with WebSockets.

We now already have the basic skills to build a dynamic site with database access, group management, partial or full HTML rendering, event control that triggers backend actions, form creation, and some security measures. One question may be echoing in your head: was it worth all the effort? Just think that we can now create SPAs with minimal use of JavaScript, we don’t need to build an API to connect the frontend and the backend, and the time between requests and their responses is ridiculously low, avoiding the use of loading in many cases. The complexity of the projects also has decreased and we can avoid the installation of several frontend libraries. Judge for yourself. The...
