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.

Exploring the containers used for building our app

Containers are processes isolated from your operating system. Docker allows us to modify them, add tools, execute scripts, and the like, all without leaving the memory space that Docker reserves for us while they are running. When we want to stop working with a container, we can stop it and any action we have performed will cease to exist. Of course, if we need to, we can save the changes in volumes. These are Docker virtual hard disks that can connect to any container that is mounted in folders; this is very useful in allowing the container to access project files or configurations.

We will use containers to create an environment that is easy to deploy, irrespective of the software or version of Python installed on the machine. In addition, we will be able to select the version for each software in a transparent way.

Let’s start by extending docker-compose.yaml by adding the following services:
