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.

Offering an RSS feed

Tech blogs are often consumed by robots, in particular by feed readers. If we want to build a feed in Django, it’s really convenient. Django incorporates a framework called Syndication that automates tasks such as dynamic generation of XML, fields, and caching.

In app/website/, we add the following class that inherits from Feed:

from django.contrib.syndication.views import Feed
from django.urls import reverse
from .models import Post
class LatestEntriesFeed(Feed):
    title = "My blog"
    link = "/feed/"
    description = "Updates to posts."
    def items(self):
        return Post.objects.all()[:5]
    def item_title(self, item):
        return item.title
    def item_description(self, item):
