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

We have acquired the skills to create a bidirectional communication tunnel between a backend and frontend using the WebSockets protocol. We can send plain text, JSON, or HTML—totally asynchronous and without waiting. We even know how to ask the backend to take care of rendering HTML fragments that we will inject without the visitor noticing a delay.

Despite everything we have learned, we still have some issues, such as the fact that the backend can only send information to individual clients, and not to groups. In addition, we still don’t know how to interact with the database, create sessions, or identify users. And without all these elements, we will be unable to make an application that facilitates communication between two visitors or manipulate the database. We need to go deeper.

In the next chapter, we will be introduced to database models and create a complete Browse-Read-Edit-Add-Delete (BREAD) with a completely new project.

BREAD Is an Evolution...
